Basics of Online Web Research, Web Mining & Data Extraction Services

The evolution of the World Wide Web and Search engines has brought the abundant and ever growing pile of data and information on our finger tips. It has now become a popular and important resource for doing information research and analysis.

Today, Web research services are becoming more and more complicated. It involves various factors such as business intelligence and web interaction to deliver desired results.

Web Researchers can retrieve web data using search engines (keyword queries) or browsing specific web resources. However, these methods are not effective. Keyword search gives a large chunk of irrelevant data. Since each webpage contains several outbound links it is difficult to extract data by browsing too.

Web mining is classified into web content mining, web usage mining and web structure mining. Content mining focuses on the search and retrieval of information from web. Usage mining extract and analyzes user behavior. Structure mining deals with the structure of hyperlinks.

Web mining services can be divided into three subtasks:

Information Retrieval (IR): The purpose of this subtask is to automatically find all relevant information and filter out irrelevant ones. It uses various Search engines such as Google, Yahoo, MSN, etc and other resources to find the required information.

Generalization: The goal of this subtask is to explore users' interest using data extraction methods such as clustering and association rules. Since web data are dynamic and inaccurate, it is difficult to apply traditional data mining techniques directly on the raw data.

Data Validation (DV): It tries to uncover knowledge from the data provided by former tasks. Researcher can test various models, simulate them and finally validate given web information for consistency.

Data Mining, Not Just a Method But a Technique

Web data mining is segregating probable clients out of huge information available on the Internet by performing various searches. It could be well organized and structured, or raw, depending on the use of the data. Web data mining could be done using a simple database program or investing money in a costly program.

Start collecting basic contact information of probable clients, such as: names, addresses, landline and cell phone numbers, email addresses and education or occupation if required.

CART and CHAID data mining

While collecting data you will find that tree-shaped structures that represent decisions. These derived decisions give rules for the classification of data collected. Precise decision tree methods include Classification and Regression Trees also know as CART data mining and Chi Square Automatic Interaction Detection also known as CHAID data mining. CART and CHAID data mining are decision tree techniques used for classification of data collected. They provide a set of rules that could be applied to unclassified data collected in prediction. CART segments a dataset creating two-way splits whereas CHAID segments using chi square tests creating multi-way splits. CART requires less data preparation compared to CHAID.

Understanding customer's actions

Keep a track of customer's actions like: what does he buy, when does he buy, why does he buy, what is the use of his buying, etc. Knowing such simple things about your customer will help you to understand needs of your customer better and thus process of data mining services will be easier and quality data would be mined. This will increase your personal relations with your customer which would finally result in a better professional relationship.

Following demography

Mine the data as per demography, dependent on geography as well as socio economic background of business location. You can use government statistics as the source of your data collection. Keeping it in mind you can go ahead with the understanding of the community existing and thus the data required.

Use your informal conversation in serving your clients better

Use minute details of your conversation and understanding with your customers to serve them. If essential, conduct surveys, send a professional gift or use some other object that helps you understand better in fulfilling customer needs. This will increase the bonding between you and your customer and you will be able to serve your customer better in providing data mining services.

Insert the collect information in a desktop database. More the information is collected you will find that you can prepare specific templates in feeding information. Using a desktop database, it is easier to make changes later on as and when required.

Maintaining privacy

While performing, it is essential to ensure that you or your team members are not violating privacy laws in gathering or providing the data information. Once trust is lost, you may also loose the customer, because trust is the base of any relationship, let it be a business relation.

Effectiveness of Web Data Mining Through Web Research

Web data mining is systematic approach to keyword based and hyperlink based web research for gaining business intelligence. It requires analytical skills to understand hyperlink structure of given website. Hyperlinks possess enormous amount of hidden human annotations that can help automatically understand the authority. If the webmaster provides a hyperlink pointing to another website or web page, this action is perceived as an endorsement to that webpage. Search engines highly focus on such endorsements to define the importance of the page and place them higher in organic search results.

However every hyperlink does not refer to the endorsement since the webmaster may have used it for other purposes, such as navigation or to render paid advertisements. It is important to note that authoritative pages rarely provide informative descriptions. For an instant, Google's homepage may not provide explicit self-description as "Web search engine."

These features of hyperlink systems have forced researchers to evaluate another important webpage category called hubs. A hub is a unique, informative webpage that offers collections of links to authorities. It may have only a few links pointing to other web pages but it links to a collection of prominent sites on a single topic. A hub directly awards authority status on sites that focus on a single topic. Typically, a quality hub points to many quality authorities, and, conversely, a web page that many such hubs link to can be deemed as a superior authority.

Such approach of identifying authoritative pages has resulted in the development of various popularity algorithms such as PageRank. Google uses PageRank algorithm to define authority of each webpage for a relevant search query. By analyzing hyperlink structures and web page content, these search engines can render better-quality search results than term-index engines such as Ask and topic directories such as DMOZ.

Building Your Profitable Content Website

Your website is an important part of your business. Not only for your online but also for many offline business. Your online presence means that you can tap into the huge and growing market of the Internet. Many people think that having your own website and setting it up is complicated and expensive but it is not necessarily so. Here are some tips to have you up and running with ease.

A. Planning your website

    Analyzing your desired visitors
    How to attract them and warm them to the sale
    Writing good content
    Your sales letter
    Your domain name
    Optimizing content

Before you build a website you will need to put some thought and planning into it. Your first step will be to decide who are your most wanted visitors. Analyze them carefully, who are they? What interests them? Where do they go? Make a thumbnail sketch and write it down for reference.

Then list all the ways you will attract them and make them stay at your site. What info content are they looking for? What sort of newsletter will interest them? Most important of all find out their needs and wants, so that you can build your product/service to fulfill these needs. List all these and keep record of them.

Make a list of all the info articles that will interest them and warm potential buyers for the sale. Put a couple on your website and keep the rest for future newsletter material.

Your sales letter: This is the heart of your business and should be done right. If you are an experienced copywriter then go ahead and write a warm persuasive personal sales letter. If you do not have experience then it is worth hiring a professional to write one for you. You can hire professional writers at Elanceor oDesk for a reasonable price. You should place your sales letter on your home page and have your info articles link into it.

Your domain name: Should have at least 1-2 keywords or even be made up of your key phrase for your business. This will help with Search engine placement and will help to brand your business in your visitors minds.

Ideally your content should be optimized so that you can be placed well with the search engines.

B. Choosing an HTML editor.

    Which one is right for you?
    How to get a free one with hosting
    Do it yourself VS having a website designed

There are 2 major HTML editors that are used commonly, Front Page and Dreamweaver. They can run you about $300-$400 but if you want to work on your site yourself will be worth it. Front page is a basic HTML editor but if your site requires PHP scripting is a little hard to work with. Dreamweaver does allow PHP scripts and is also easy to use. Do a comparison check and see which one will work for you.

If you have Yahoo hosting they provide a free HTML editor, which is quite easy to use.

If you have the funds you may want to have your site designed, especially if you have a service, where credibility is very important. Making your own website can be quite time consuming and although rewarding is not for everyone.

C. Designing your website

    Your content-Preselling points
    Free give a ways
    Layout/Presentation
    Use of graphics
    Forms instead of email
    Basic web promotion
    Newsletter

When you write your web content you can use a couple of your best articles about your subject. Visitors will enjoy this and see you as an expert in your field. This boosts your credibility, wins trust and warms your potential buyer for the sale.Product reviews are also good selling points. Landing pages for direct advertising is always good; these can and should be optimized for search engine traffic.

Free info can be offered in the form of reports and e-courses. These can be given as a bonus for subscribing to your newsletter.

Your layout is important. Navigation should be simple and easy for your visitors, usually on the left hand side. Keep your layout professional and businesslike with normal font (Times Roman, Ariel or Veranda in normal size font). Black on white background is good for a business site. Try to use just 2 colors at the most to keep it looking businesslike. A simple template looks good for a business website. Try to find one that matches your topic.

Use graphics sparingly. Business websites should always look sober and professional. Small graphics are good to emphasize a point and book covers help to sell e-books and software.

Use forms instead of email addresses on your website for the contact us and about us section. This will cut down Spammers harvesting your email address.

Basic web promotion includes search engine submission, Pay-per-clicks, Google ad campaigns, and linking to related sites. Article distribution is also a powerful way to get targeted traffic to your site.

A free newsletter is a must for capturing visitors email addresses and building your business list.

Building your website can be a fun and rewarding task. However it does take time and good planning. With these few points you will be able to build a profit pulling website, that will continue to make you money for years to come.

Data Destruction Service

Data destruction is a term that refers to the removal or eradication of magnetic or optical computer storage media. The method of destruction varies, dependent upon the medium and method used in the process. The aim of data destruction is to physically destroy the data so as to remove the possibility of recovery.

Computer storage media requires some form of sanitization at the end of it's working life, particularly when it holds sensitive information that could inadvertently be read by third parties. This is extremely relevant to businesses and corporations, where data may contain information pertaining to the general public or third parties, such as clients. Similarly, confidential corporate information, including patent designs, business strategies and other sensitive data could easily be accessed by third parties if the data is not removed.

As I said at the outset, methods of destruction vary, depending upon storage medium. For each storage medium, a variety of destruction techniques also exist.

Optical media, such as cd roms, DVDs can be destroyed by granulating the plastics into 5mm chips. This method does not remove the data, but makes recovery near impossible. However, removal of the thin film that coats the top side of the disk, by scraping, scouring or sanding will physically destroy the data. By contrast, the use of microwave ovens, a less conventional technique, is highly effective due to the static charge and consequent arcing across the thin film storage layer of the disk.

Typical modern magnetic media constitutes tape backup units and Hard Disk drives. Unfortunately, tape backup units are very hard to destroy, due to the length of the tape, upon which a film of iron oxide layer retains the magnetic media. Shredding of such media is possible, but requires significant financial investment in plant capable of handling such devices. Acids, in particular, Nitric acid, at 50% concentration, will react violently with the iron oxide layer, destroying it completely within minutes. However, this process requires the removal of the outer plastic case to adequately expose the internal media storage tape. In some circumstances, incineration of the storage media may be an option. However, this may inadvertently expose the operator to carenogens and may be prohibited in certain countries.

The variety of Hard Disk drives available, method of connectivity (SATA, IDA, ATA, SCA, SCSI) means that data destruction software has had to be intelligent enough to differentiate between these different interfaces. Software driven destruction of hard drives is a highly efficient eradication technique that has been shrouded in urban myths, masking the true ease with which data can be permanently removed. In many instances, a single pass binary wipe (writing random zeros and ones to the drive) will permanently remove all data from the storage device. However, international standards exist, which all require more significant wiping processes, most of which will inadvertently result in complete failure of the hard drive due to the high temperatures generated.

Hard drive destruction may also be undertaken via other means, including the granulating of the drive to 5mm particulate level, use of a furnace to destroy and ultimately recover the Aluminium and use of corrosive materials such as Acids to remove the recording surfaces from the disk.

All the above methods are quantifiable, in that the destruction of the data can be confirmed, etheri via visual inspection of the drive storage device or by a software interface. However, the final data destruction technique, that known as degaussing, whereby a strong electromagnet is used to remove the magnetically stored data has no method of validation. It is for this reason that this has technique has been left until last. It is for this reason that the US government and military require the use of a deguasser that has been approved by the NSA.

The Need for Specialised Data Mining Techniques for Web 2.0

Web 2.0 is not exactly a new version of the Web, but rather a way to describe a new generation of interactive websites centred on the user. These are websites that offer

interactive information sharing, as well as collaboration - a case in point being wikis and blogs - and is now expanding to other areas as well. These new sites are the result of new technologies and new ideas and are on the cutting edge of Web development. Due to their novelty, they create a rather interesting challenge for data mining.

Data mining is simply a process of finding patterns in masses of data. There is such a vast plethora of information out there on the Web that it is necessary to use data mining tools to make sense of it. Traditional data mining techniques are not very effective when used on these new Web 2.0 sites because the user interface is so varied. Since Web 2.0 sites are created largely by user-supplied content, there is even more data to mine for valuable information. Having said that, the additional freedom in the format ensures that it is much more difficult to sift through the content to find what is usable.The data available is very valuable, so where there is a new platform, there must be new techniques developed for mining the data. The trick is that the data mining methods must themselves be flexible as the sites they are targeting are flexible. In the initial days of the World Wide Web, which was referred to as Web 1.0, data mining programs knew where to look for the desired information. Web 2.0 sites lack structure, meaning there is no single spot for the mining program to target. It must be able to scan and sift through all of the user-generated content to find what is needed. The upside is that there is a lot more data out there, which means more and more accurate results if the data can be properly utilized. The downside is that with all that data, if the selection criteria are not specific enough, the results will be meaningless. Too much of a good thing is definitely a bad thing. Wikis and blogs have been around long enough now that enough research has been carried out to understand them better. This research can now be used, in turn, to devise the best possible data mining methods. New algorithms are being developed that will allow data mining applications to analyse this data and return useful. Another problem is that there are many cul-de-sacs on the internet now, where groups of people share information freely, but only behind walls/barriers that keep it away from the genera results.

The main challenge in developing these algorithms does not lie with finding the data, because there is too much of it. The challenge is filtering out irrelevant data to get to the meaningful one. At this point none of the techniques are perfected. This makes Web 2.0 data mining an exciting and frustrating field, and yet another challenge in the never ending series of technological hurdles that have stemmed from the internet. There are numerous problems to overcome. One is the inability to rely on keywords, which used to be the best method to search. This does not allow for an understanding of context or sentiment associated with the keywords which can drastically vary the meaning of the keyword population. Social networking sites are a good example of this, where you can share information with everyone you know, but it is more difficult for that information to proliferate outside of those circles. This is good in terms of protecting privacy, but it does not add to the collective knowledge base and it can lead to a skewed understanding of public sentiment based on what social structures you have entry into. Attempts to use artificial intelligence have been less than successful because it is not adequately focused in its methodology. Data mining depends on the collection of data and sorting the results to create reports on the individual metrics that are the focus of interest. The size of the data sets are simply too large for traditional computational techniques to be able to tackle them. That is why a new answer needs to be found. Data mining is an important necessity for managing the backhaul of the internet. As Web 2.0 grows exponentially, it is increasingly hard to keep track of everything that is out there and summarize and synthesize it in a useful way. Data mining is necessary for companies to be able to really understand what customers like and want so that they can create products to meet these needs. In the increasingly aggressive global market, companies also need the reports resulting from data mining to remain competitive. If they are unable to keep track of the market and stay abreast of popular trends, they will not survive. The solution has to come from open source with options to scale databases depending on needs. There are companies that are now working on these ideas and are sharing the results with others to further improve them. So, just as open source and collective information sharing of Web 2.0 created these new data mining challenges, it will be the collective effort that solves the problems as well.

It is important to view this as a process of constant improvement, not one where an answer will be absolute for all time. Since its advent, the internet has changed quite significantly as well as the way users interact with it. Data mining will always be a critical part of corporate internet usage and its methods will continue to evolve just as the Web and its content does.

There is a huge incentive for creating better data mining solutions to tackle the complexities of Web 2.0. For this reason, several companies exist just for the purpose of analysing and creating solutions to the data mining problem. They find eager buyers for their applications in companies which are desperate for information on markets and potential customers.
