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.

What Are Document Scanning Services Used For?

There are a whole host of companies and organisations that utilise document scanning services in the UK, and in this article we'll look at some of those types of organisation and what they use scanning services for.

The vast majority of document scanning services are able to scan images of various sizes - often from items as small as a receipt to huge A0 drawings. The storage of paper documents can take up a huge amount of space, and while people may not wish to scan their documents or drawings and then get rid of them - they will be able to store them in a more remote location, and be able to utilise more local space for other things.

Perhaps more importantly, once document scanning services have been used to scan documents/drawings etc., they are extremely easy to access and view by whoever needs to see them. When one considers that up to 5000 large documents can be archived onto a single CD ROM, then it becomes apparent just how much easier it is to store some documents this way, rather than having to sift through many real documents - saving time and money in terms of man hours.

In order to make the viewing process as easy as possible, many document scanning services convert documents to the popular PDF format file. These are considered a good option because they can be easily opened by anyone who needs to see it - the PDF reader is free to download too. As part of this file type, there is the PDF Searchable file, which as the name suggests allows the document to be searched. This is something that can save many businesses and organisations a great deal of time in the long run; it uses Optical Recognition Software which recognises the letters in a printed document and converts them to searchable words, letters and numbers.

There are a huge range of industries that use document scanning services, from financial and legal, through to construction and local authority. Paper documents continue to be a very important way of keeping track of all manner of events and plans, but the huge amount of space they take up means that the ability to scan documents has become invaluable in speeding up activities in all manner of organisations.

Scanning documents is not always a cost effective option for some organisations though, which is why some firms provide a scan-on-demand service, which means certain regularly used documents can be scanned and stored for retrieval.

Gino Hitshopi is highly experienced in the realm of document scanning services, having worked in the document scanning industry for many years.
