Data Mining - Retrieving Information From Data

Data mining definition is the process of retrieving information from data. It has become very important now days because data that is processed is usually kept for future reference and mainly for security purposes in a company. Data transforms is processed into information and it is mostly used in different ways depending on what information one is extracting and from where the person is extracting the information.

It is commonly used in marketing, scientific information and research work, fraud detection and surveillance and many more and most of this work is done using a computer. This definition can come in different terms data snooping, data fishing and data dredging all this refer to data mining but it depends in which department one is. One must know data mining definition so that he can be in a position to make data.

The method of data mining has been there for so many centuries and it is used up to date. There were early methods which were used to identify data mining there are mainly two: regression analysis and bayes theorem. These methods are never used now days because a lot of people have advanced and technology has really changed the entire system.

With the coming up or with the introduction of computers and technology, it becomes very fast and easy to save information. Computers have made work easier and one can be able to expand more knowledge about data crawling and learn on how data is stored and processed through computer science.

Computer science is a course that sharpens one skill and expands more about data crawling and the definition of what data mining means. By studying computer science one can be in a position to know: clustering, support vector machines and decision trees there are some of the units that are found on computer science.

It's all about all this and this knowledge must be applied here. Government institutions, small scale business and supermarkets use data.

The main reason most companies use data mining is because data assist in the collection of information and observations that a company goes through in their daily activity. Such information is very vital in any companies profile and needs to be checked and updated for future reference just in case something happens.

Businesses which use data crawling focus mainly on return of investments, and they are able to know whether they are making a profit or a loss within a very short period. If the company or the business is making a profit they can be in a position to give customers an offer on the product in which they are selling so that the business can be a position to make more profit in an organization, this is very vital in human resource departments it helps in identifying the character traits of a person in terms of job performance.

Most people who use this method believe that is ethically neutral. The way it is being used nowadays raises a lot of questions about security and privacy of its members. Data mining needs good data preparation which can be in a position to uncover different types of information especially those that require privacy.

A very common way in this occurs is through data aggregation.

Data aggregation is when information is retrieved from different sources and is usually put together so that one can be in a position to be analyze one by one and this helps information to be very secure. So if one is collecting data it is vital for one to know the following:

    How will one use the data that he is collecting?
    Who will mine the data and use the data.
    Is the data very secure when am out can someone come and access it.
    How can one update the data when information is needed
    If the computer crashes do I have any backup somewhere.

It is important for one to be very careful with documents which deal with company's personal information so that information cannot easily be manipulated.

Basics of Web Data Mining and Challenges in Web Data Mining Process

Today World Wide Web is flooded with billions of static and dynamic web pages created with programming languages such as HTML, PHP and ASP. Web is great source of information offering a lush playground for data mining. Since the data stored on web is in various formats and are dynamic in nature, it's a significant challenge to search, process and present the unstructured information available on the web.

Complexity of a Web page far exceeds the complexity of any conventional text document. Web pages on the internet lack uniformity and standardization while traditional books and text documents are much simpler in their consistency. Further, search engines with their limited capacity can not index all the web pages which makes data mining extremely inefficient.

Moreover, Internet is a highly dynamic knowledge resource and grows at a rapid pace. Sports, News, Finance and Corporate sites update their websites on hourly or daily basis. Today Web reaches to millions of users having different profiles, interests and usage purposes. Every one of these requires good information but don't know how to retrieve relevant data efficiently and with least efforts.

It is important to note that only a small section of the web possesses really useful information. There are three usual methods that a user adopts when accessing information stored on the internet:

• Random surfing i.e. following large numbers of hyperlinks available on the web page.
• Query based search on Search Engines - use Google or Yahoo to find relevant documents (entering specific keywords queries of interest in search box)
• Deep query searches i.e. fetching searchable database from eBay.com's product search engines or Business.com's service directory, etc.

To use the web as an effective resource and knowledge discovery researchers have developed efficient data mining techniques to extract relevant data easily, smoothly and cost-effectively.

Why Web Scraping Software Won't Help

How to get continuous stream of data from these websites without getting stopped? Scraping logic depends upon the HTML sent out by the web server on page requests, if anything changes in the output, its most likely going to break your scraper setup.

If you are running a website which depends upon getting continuous updated data from some websites, it can be dangerous to reply on just a software.

Some of the challenges you should think:

1. Web masters keep changing their websites to be more user friendly and look better, in turn it breaks the delicate scraper data extraction logic.

2. IP address block: If you continuously keep scraping from a website from your office, your IP is going to get blocked by the "security guards" one day.

3. Websites are increasingly using better ways to send data, Ajax, client side web service calls etc. Making it increasingly harder to scrap data off from these websites. Unless you are an expert in programing, you will not be able to get the data out.

4. Think of a situation, where your newly setup website has started flourishing and suddenly the dream data feed that you used to get stops. In today's society of abundant resources, your users will switch to a service which is still serving them fresh data.

Getting over these challenges

Let experts help you, people who have been in this business for a long time and have been serving clients day in and out. They run their own servers which are there just to do one job, extract data. IP blocking is no issue for them as they can switch servers in minutes and get the scraping exercise back on track. Try this service and you will see what I mean here.

Data Mining Explained

Overview
Data mining is the crucial process of extracting implicit and possibly useful information from data. It uses analytical and visualization techniques to explore and present information in a format which is easily understandable by humans.

Data mining is widely used in a variety of profiling practices, such as fraud detection, marketing research, surveys and scientific discovery.

In this article I will briefly explain some of the fundamentals and its applications in the real world.

Herein I will not discuss related processes of any sorts, including Data Extraction and Data Structuring.

The Effort
Data Mining has found its application in various fields such as financial institutions, health-care & bio-informatics, business intelligence, social networks data research and many more.

Businesses use it to understand consumer behavior, analyze buying patterns of clients and expand its marketing efforts. Banks and financial institutions use it to detect credit card frauds by recognizing the patterns involved in fake transactions.

The Knack
There is definitely a knack to Data Mining, as there is with any other field of web research activities. That is why it is referred as a craft rather than a science. A craft is the skilled practicing of an occupation.

One point I would like to make here is that data mining solutions offers an analytical perspective into the performance of a company depending on the historical data but one need to consider unknown external events and deceitful activities. On the flip side it is more critical especially for Regulatory bodies to forecast such activities in advance and take necessary measures to prevent such events in future.

In Closing
There are many important niches of Web Data Research that this article has not covered. But I hope that this article will provide you a stage to drill down further into this subject, if you want to do so!

Should you have any queries, please feel free to mail me. I would be pleased to answer each of your queries in detail.

Has It Been Done Before? Optimize Your Patent Search Using Patent Scraping Technology

Has it been done before? Optimize your Patent Search using Patent Scraping Technology.

Since the US patent office opened in 1790, inventors across the United States have been submitting all sorts of great products and half-baked ideas to their database. Nowadays, many individuals get ideas for great products only to have the patent office do a patent search and tell them that their ideas have already been patented by someone else! Herin lies a question: How do I perform a patent search to find out if my invention has already been patented before I invest time and money into developing it?

The US patent office patent search database is available to anyone with internet access.

US Patent Search Homepage

Performing a patent search with the patent searching tools on the US Patent office webpage can prove to be a very time consuming process. For example, patent searching the database for "dog" and "food" yields 5745 patent search results. The straight-forward approach to investigating the patent search results for your particular idea is to go through all 5745 results one at a time looking for yours. Get some munchies and settle in, this could take a while! The patent search database sorts results by patent number instead of relevancy. This means that if your idea was recently patented, you will find it near the top but if it wasn't, you could be searching for quite a while. Also, most patent search results have images associated with them. Downloading and displaying these images over the internet can be very time consuming depending on you internet connection and the availability of the patent search database servers.

Because patent searches take such a long time, many companies and organizations are looking ways to improve the process. Some organizations and companies will hire employees for the sole purpose of performing patent searches for them. Others contract out the job to small business that specialize in patent searches. The latest technology for performing patent searches is called patent scraping.

Patent scraping is the process of writing computer automated scripts that analyze a website and copy only the content you are interested in into easily accessible databases or spreadsheets on your computer. Because it is a computerized script performing the patent search, you don't need a separate employee to get the data, you can let it run the patent scraping while you perform other important tasks! Patent scraping technology can also extract text content from images. By saving the images and textual content to your computer, you can then very efficiently search them for content and relevancy; thus saving you lots of time that could be better spent actually inventing something!

To put a real-world face on this, let us consider the pharmaceutical industry. Many different companies are competing for the patent on the next big drug. It has become an indispensible tactic of the industry for one company to perform patent searches for what patents the other companies are applying for, thus learning in which direction the research and development team of the other company is taking them. Using this information, the company can then choose to either pursue that direction heavily, or spin off in a different direction. It would quickly become very costly to maintain a team of researchers dedicated to only performing patent searches all day. Patent scraping technology is the means for figuring out what ideas and technologies are coming about before they make headline news. It is by utilizing patent scraping technology that the large companies stay up to date on the latest trends in technology.

While some companies choose to hire their own programming team to do their patent scraping scripts for them, it is much more cost effective to contract out the job to a qualified team of programmers dedicated to performing such services.

Top 10 Small Business Ideas for 2012

Starting a small business takes a lot of planning and the ability to execute your business plans. Though it doesn't require a big capital for a small business however you cannot lose your capital as this will cause a serious trouble on the financial front at the same time your future expansion plans. If you have knowledge about how to run a business successfully, you won't be able to take a wrong move that can affect your business plans. Before we go on further to the small business ideas, refer to the tips for running a small business.

• Can it sustain your everyday expenses and can it profit you.

• Can it raise enough funds to get it running for a long time and can become a profitable venture.

• Is it something that is needed everyday and does it has an appeal to sell on a steady basis?

• Is it something that you know how to do and can you do it well?

• Is it something that you like to do and doesn't mind you at all doing it over and over again?

Now that we know our objective in putting up a small business let's go forward and see what are the best idea for small business this 2012.

1. Online business - this may include article writing/blogging, virtual assistant, translator, copy writer or bookkeeper, data entry, etc. This is one of the ideal business ideas for beginners would be to take advantage of various online business opportunities. By doing online data entry and online paid survey jobs, you can earn money per hour for your work. The more accuracy and consistency you show in your job, the more work you will get.

2. Mobile apps development - almost all people nowadays possesses a mobile phone and included on the mobile phone is application that people always uses. Calendars, Alarm Clocks, notepads are some example of applications that are commonly downloaded. Whether this is a businessman, a politician, an artist or just an ordinary person has a lot or even tons of mobile application.

3. Make-up artist or hair salons - Providing either makeup artist services or hair salons is yet another interesting small business idea. Makeup artists are in great demand in the fashion and entertainment industry. If you have the required makeup skills and talent, you can start your own company and do the makeup of television and movie stars. By providing good service, you can get long-term contracts which will increase your revenues greatly. The great thing about hair salons is that they are a sure thing. No matter how dismal the economic climate, women will still scrape together the money to get their hair done, even if they have to let their nails go. So hair salons with talented stylists and well-priced services will still be real money makers.

4. Cleaning services (pool, yard, garage etc.) - A cleaning service is a good business proposition for a person who relishes the idea of cleaning apartments, homes and commercial establishments. Housekeeping is an art and people are typically deterred by the prospect of getting grease, tough stains and odors out of carpets, keeping their bathroom clean and eliminating odors from their refrigerator. Hence, a cleaning service can be a steady source of income assuming that there are no immediate competitors. Otherwise, one would have to spend money on advertising and this may eat into one's profits. Cleaning services can operate round the clock since residential apartments are generally cleaned during the day while commercial buildings are cleaned after office-hours. Considering that cleaning services earn popularity and goodwill through word of mouth, a job that is well done will rarely go unnoticed.

5. Elder assistant or baby sitting - being a babysitter doesn't require you to have a license, with more parents needing to work and offering a home based child care can be a great way of starting your own business while taking care of your own kids too. The growing numbers of senior baby boomers also provide growing business opportunities for senior care. In-home care and senior residences are the obvious ones, but don't forget all the related opportunities such as driving, delivery, catering and cleaning services for seniors who want to stay in their homes. You can certainly develop your own business providing care for seniors.

6. Recycler - the best thing of being a recycler is that you're not just earning your own money and you're also helping the environment. Average homeowner doesn't always know where or how to recycle the stuff they've got. A pickup truck are all you'd need to start buying or simply offering to remove scrap metal, old computers, electronics, ink cartridges and other recyclable materials.

7. Event management/party planner - Event management or party planning can also be a good option for a small business. Event planners have to organize a particular event by taking into consideration the suggestions given by their clients. This job requires creativity, patience and ability to get work done from people on time. It can help you be a successful event planner if have a good team of creative professional that can help you organize the event under you.

8. Online selling - whether this is a pre-loved or brand-new stuff you can still earn big bucks. This is being popularized by e-bay. There are still some people who have a whole lot of money and are willing to spend it on the name products that matter. Luxury handbags, scarves, and shoes for women are still selling well, for instance.

9. Social media consultants - With the ever rising of the social media era and the giant social networking sites, such as Facebook, Twitter, and You tube, businesses have been taking advantage of this to gain more exposure for their brands and products. With more than 800 million active users in Facebook alone, business promotion in this top social networking site is now a priority for business owners and marketers. If you have the social media marketing skills that can outsource likes and follows for your client's business, then this business can help you earn cold cash on the Internet.

10. Pet related services such as pet sitter, pet cleaning and grooming services - Most Canadians and Americans loves pet especially dogs and feeding, caring for them and pampering their pooches a spending priority. Kennels, doggie daycare, dog treat bakeries and dog resorts are few of the things that you may want to venture in.

These are not necessarily ideas for businesses that anyone can start however you can get some idea on the list above. But in my opinion, these are business opportunities that are going to provide real chances to make money in 2012 and beyond. Business that is done right, in the right place and for the right people may be profitable enterprises for years to come. If you've been considering a sale in 2012, take your time and do it right. Plan ahead, research your market and stand out from the competition. Knowing the sales process is half the battle. With proper preparation, you can ensure a stress free transition and a financially successful exit from your business.

Featured: Flixster [dot] Com

Flixster.com is an online database of information about films and actors. It includes social features such as the ability for individual users to review and rate films and to compare their ratings with invited friends to assess compatibility in film tastes.

I tried flixster for the first time a few weeks ago and was quite surprised with the easy navigation error free environment, one thing I’m not a big fan of is the automatically email everyone in your address book trick, but I guess they have to get the initial traffic somehow, one thing I really liked is how they encourage you to customize your profile right after sign up, offering a choice of hundreds of film and movie-star inspired backgrounds.

You can also choose a movie star to be your avatar, or upload a photo of yourself. Next up, they ask you to rate 50 films to ascertain your preferences: in short, they quickly grab a bunch of data about the users and meld them in to the community. A couple of cool features I liked were, how they allow you to post the results of your MCT (Movie Compatibility Test) to all your friends through MySpace bulletin and offer to post all your movie reviews to the “Movies” section on your MySpace profile.


Unlike other social network sites, flixster concentrates on what it should, the content. Not only can you continue rating movies, but you can take quizzes (and make them), explore new movies this week, watch trailers and clips, find photos and posters, write and browse reviews and find new profile skins in the skin gallery.If you don’t like the skins they offer and have an artistic vein, you can create your own and submit them to the skin gallery.

There’s tons of things more that you will find along the way, I just blew 3 hours browsing actors profiles, rating movies and reviewing them.The thing that attracted me to Flixster wasn’t actually the whole social network thing but the feature of allowing users to make their own unlimited movie lists (unlike RottenTomatoes), the adding friends and comparing movie tastes is just a bonus. I think Flixster has all the necessary potential of a successful site and look forward to seeing great things from them.

Three Common Methods For Web Data Extraction

Probably the most common technique used traditionally to extract data from web pages this is to cook up some regular expressions that match the pieces you want (e.g., URL's and link titles). Our screen-scraper software actually started out as an application written in Perl for this very reason. In addition to regular expressions, you might also use some code written in something like Java or Active Server Pages to parse out larger chunks of text. Using raw regular expressions to pull out the data can be a little intimidating to the uninitiated, and can get a bit messy when a script contains a lot of them. At the same time, if you're already familiar with regular expressions, and your scraping project is relatively small, they can be a great solution.

Other techniques for getting the data out can get very sophisticated as algorithms that make use of artificial intelligence and such are applied to the page. Some programs will actually analyze the semantic content of an HTML page, then intelligently pull out the pieces that are of interest. Still other approaches deal with developing "ontologies", or hierarchical vocabularies intended to represent the content domain.

There are a number of companies (including our own) that offer commercial applications specifically intended to do screen-scraping. The applications vary quite a bit, but for medium to large-sized projects they're often a good solution. Each one will have its own learning curve, so you should plan on taking time to learn the ins and outs of a new application. Especially if you plan on doing a fair amount of screen-scraping it's probably a good idea to at least shop around for a screen-scraping application, as it will likely save you time and money in the long run.

So what's the best approach to data extraction? It really depends on what your needs are, and what resources you have at your disposal. Here are some of the pros and cons of the various approaches, as well as suggestions on when you might use each one:

Raw regular expressions and code

Advantages:

- If you're already familiar with regular expressions and at least one programming language, this can be a quick solution.

- Regular expressions allow for a fair amount of "fuzziness" in the matching such that minor changes to the content won't break them.

- You likely don't need to learn any new languages or tools (again, assuming you're already familiar with regular expressions and a programming language).

- Regular expressions are supported in almost all modern programming languages. Heck, even VBScript has a regular expression engine. It's also nice because the various regular expression implementations don't vary too significantly in their syntax.

Disadvantages:

- They can be complex for those that don't have a lot of experience with them. Learning regular expressions isn't like going from Perl to Java. It's more like going from Perl to XSLT, where you have to wrap your mind around a completely different way of viewing the problem.

- They're often confusing to analyze. Take a look through some of the regular expressions people have created to match something as simple as an email address and you'll see what I mean.

- If the content you're trying to match changes (e.g., they change the web page by adding a new "font" tag) you'll likely need to update your regular expressions to account for the change.

- The data discovery portion of the process (traversing various web pages to get to the page containing the data you want) will still need to be handled, and can get fairly complex if you need to deal with cookies and such.

When to use this approach: You'll most likely use straight regular expressions in screen-scraping when you have a small job you want to get done quickly. Especially if you already know regular expressions, there's no sense in getting into other tools if all you need to do is pull some news headlines off of a site.

Ontologies and artificial intelligence

Advantages:

- You create it once and it can more or less extract the data from any page within the content domain you're targeting.

- The data model is generally built in. For example, if you're extracting data about cars from web sites the extraction engine already knows what the make, model, and price are, so it can easily map them to existing data structures (e.g., insert the data into the correct locations in your database).

- There is relatively little long-term maintenance required. As web sites change you likely will need to do very little to your extraction engine in order to account for the changes.

Disadvantages:

- It's relatively complex to create and work with such an engine. The level of expertise required to even understand an extraction engine that uses artificial intelligence and ontologies is much higher than what is required to deal with regular expressions.

- These types of engines are expensive to build. There are commercial offerings that will give you the basis for doing this type of data extraction, but you still need to configure them to work with the specific content domain you're targeting.

- You still have to deal with the data discovery portion of the process, which may not fit as well with this approach (meaning you may have to create an entirely separate engine to handle data discovery). Data discovery is the process of crawling web sites such that you arrive at the pages where you want to extract data.

When to use this approach: Typically you'll only get into ontologies and artificial intelligence when you're planning on extracting information from a very large number of sources. It also makes sense to do this when the data you're trying to extract is in a very unstructured format (e.g., newspaper classified ads). In cases where the data is very structured (meaning there are clear labels identifying the various data fields), it may make more sense to go with regular expressions or a screen-scraping application.

Screen-scraping software

Advantages:

- Abstracts most of the complicated stuff away. You can do some pretty sophisticated things in most screen-scraping applications without knowing anything about regular expressions, HTTP, or cookies.

- Dramatically reduces the amount of time required to set up a site to be scraped. Once you learn a particular screen-scraping application the amount of time it requires to scrape sites vs. other methods is significantly lowered.

- Support from a commercial company. If you run into trouble while using a commercial screen-scraping application, chances are there are support forums and help lines where you can get assistance.

Disadvantages:

- The learning curve. Each screen-scraping application has its own way of going about things. This may imply learning a new scripting language in addition to familiarizing yourself with how the core application works.

- A potential cost. Most ready-to-go screen-scraping applications are commercial, so you'll likely be paying in dollars as well as time for this solution.

- A proprietary approach. Any time you use a proprietary application to solve a computing problem (and proprietary is obviously a matter of degree) you're locking yourself into using that approach. This may or may not be a big deal, but you should at least consider how well the application you're using will integrate with other software applications you currently have. For example, once the screen-scraping application has extracted the data how easy is it for you to get to that data from your own code?

When to use this approach: Screen-scraping applications vary widely in their ease-of-use, price, and suitability to tackle a broad range of scenarios. Chances are, though, that if you don't mind paying a bit, you can save yourself a significant amount of time by using one. If you're doing a quick scrape of a single page you can use just about any language with regular expressions. If you want to extract data from hundreds of web sites that are all formatted differently you're probably better off investing in a complex system that uses ontologies and/or artificial intelligence. For just about everything else, though, you may want to consider investing in an application specifically designed for screen-scraping.

As an aside, I thought I should also mention a recent project we've been involved with that has actually required a hybrid approach of two of the aforementioned methods. We're currently working on a project that deals with extracting newspaper classified ads. The data in classifieds is about as unstructured as you can get. For example, in a real estate ad the term "number of bedrooms" can be written about 25 different ways. The data extraction portion of the process is one that lends itself well to an ontologies-based approach, which is what we've done. However, we still had to handle the data discovery portion. We decided to use screen-scraper for that, and it's handling it just great. The basic process is that screen-scraper traverses the various pages of the site, pulling out raw chunks of data that constitute the classified ads. These ads then get passed to code we've written that uses ontologies in order to extract out the individual pieces we're after. Once the data has been extracted we then insert it into a database.
