Web2DB :  Web Data Extraction Service
Extract data from target websites, Save web content to your database(Access/Excel/CSV)Using the Web2DB Service, it has now become possible for you to instantly extract many key information fields from a great number of web pages that are usually read only by man, and converse them into your own topic databases such as the databases of your potential customer, company’s information, human talent, commodity, project requirement, pictures, news, gene, books and publication, treatise etc., and many, many more. In a word, you can collect all message you are interest in, and change them into your own property, thus to fully support your various objectives such as marketing promotion, business expansion, website construction, content integration, knowledge acquirement, as well as technological research etc.

Without extraction tools Tools are needed to manage all available information including the Web, subscription services, and internal data stores. Without an extraction tool (a product specifically designed to find, organize, and output the data you want), you have very poor choices for getting information. Your choices are:

Use search engines Search engines help find some Web information, but they do not pinpoint information, cannot fill out web forms they encounter to get you the information you need, are perpetually behind in indexing content, and at best, can only go two or three levels deep into a Web site. And they cannot search file directories on your network.

Create custom programming Custom programming is costly, can be buggy, requires maintenance, and takes time to develop. Plus the programs must be constantly updated as the location of information frequently changes.

Inefficient methods means the information analyst spends time finding, collecting, and aggregating data instead of analyzing data and gaining the competitive edge. This also affects the application programmer who has to spend time developing extraction tools instead of developing tools for the core business.
New solutions improve productivity
Extraction tools using a concise notation to define precise navigation and extraction rules greatly reduce the time spent on systematic collection efforts. Tools that support a variety of format options provide a single development platform for all collection needs regardless of electronic information source.Early attempts at software tools for “Web harvesting” and unstructured data mining emerged, and started to get the attention of information professionals. These products did a reasonable job of finding and extracting Web information for intelligence gathering purposes. But this was not enough. Organizations needed to reach the “deep Web” and other electronic information sources, capabilities beyond simplistic Web content clipping.

A new generation of information extraction tools is markedly improving productivity for information analysts and application developers.
Uses for extraction tools
The most popular applications for information extraction tools remain competitive intelligence gathering and market research, but there are some new applications emerging as organizations learn how to better use the functionality in the new generation of tools.Deep Web price gathering The explosion of e-tailing, e-business, and e-government makes a plethora of competitive pricing information available on Web sites and government information portals. Unfortunately, price lists are difficult to extract without selecting product categories or filling out Web forms. Also, some prices are buried deep in .pdf documents. Automated forms completion and automated downloading are necessary features to retrieve prices from the deep Web.

Primary research Message boards, e-pinion sites, and other Web forums provide a wealth of public opinion and user experience information on consumer products, air travel, test drives, experimental drugs, etc. While much of Data Mining this information can be found with a search engine, features like simultaneous board crawling, selective content extraction, task scheduling, and custom output reformatting are only available with extraction tools.

Content aggregation for information portals Content is exploding and available from Web and non-Web sources. Extraction tools can crawl the Web, internal information sources, and subscription services to automatically populate portals with pertinent content such as competitive information, news, and financial data.

Supporting CRM systems The Web is a valuable source of external data to selectively populate a data warehouse or a CRM database. To date most organizations focus on aggregating internal data for their data warehouses and CRM systems. Now, however, some organizations are realizing the value of adding external data as well. In the book Web Farming for the Data Warehouse from Morgan Kaufman Publishers, Dr. Richard Hackathorn writes, “It is the synergism of external market information with internal customer data that creates the greatest business benefit.”

Business activity monitoring Extraction tools can continuously monitor dynamically changing information sources to provide real time alerts and to populate information portals and dashboards.

Wrappers are specialised program routines that automatically extract data from Internet websites and convert the information into a structured format. More specifically, wrappers have three main functions. Firstly, they must be able to download HTML pages from a website. Secondly, search for, recognise and extract specified data. Thirdly, save this data in a suitably structured format to enable further manipulation . The data can then be imported into other applications for additional processing. According to [20], over 80% of the published information on the WWW is based on databases running in the background. When compiling this data into HTML documents the structure of the underlying databases is completely lost. Wrappers try to reverse this process by restoring the information to a structured format . With the right programs, it is even possible to use the WWW as a large database. By using several wrappers to extract data from the various information sources of the WWW, the retrieved data can be made available in an appropriately structured format .

As a rule, a specially developed wrapper is required for each individual data source, because of the different and unique structures of websites. The WWW is also extremely dynamic and continually evolving, which results in frequent changes in the structures of websites. Consequently, it is often necessary to constantly update or even completely rewrite existing wrappers, in order to maintain the desired data extraction capabilities . The Extensible Markup Language (XML) has the potential to alleviate such problems. Whereas HTML is presentation oriented, XML keeps the data structure separate from the presentation. However, it may take some time before all data is provided in the XML format, and it remains to be seen whether XML can establish itself in all areas of electronic information processing . Taking into consideration that XML documents are based on varying Document Type Definitions (DTD) or XML-Schemas, the current problems regarding data extraction from HTML documents can be reduced, but not completely resolved. Wrappers will, therefore, retain an important role in the integration of data from WWW sources for some time to come.

Wrapper-Generating Toolkits
Every wrapper can be manually developed from scratch, for example, in an established programming language using regular expressions. For smaller applications, this can prove to be a sensible approach. However, if the use of a larger number of wrappers is required, this inevitably leads to the use of so-called toolkits, which can generate a complete wrapper based on user defined parameters for a given data source. One of the most important features of generated wrappers is the format in which the extracted data can be exported. If, for example, the extracted data is converted into an XML format, then it can be imported and processed by a large number

of software applications. Toolkits for generating wrappers can be differentiated in a number of ways. They can be categorised by their output methods, interface type, Web crawling capability, use of a graphical user interface (GUI) and several other characteristics. Laender et al.
[12] categorise a number of toolkits based on the methods used for generating wrappers. These methods include specially designed wrapper development languages and algorithms based on HTML-awareness, induction, modelling, ontology and natural language processing. However, a detailed presentation of such technical details is beyond the scope of this survey paper Data Feed Extraction . Therefore, the toolkits are simply divided into two basic categories based on commercial and non-commercial availability.

The wrapper generating programs within both of these categories offer several different means of user interaction. Some toolkits are solely based on command lines and require routines developed in a pre-determined unique scripting language, in order to generate an appropriate wrapper for a specified data source. These wrapper development scripting languages are used in standard text editors and can be seen as application specific alternatives to general-purpose languages such as Perl and Java. A large number of toolkits offer a GUI, whereby the relevant data within an HTML document is highlighted with a mouse, and the program then generates a wrapper based on the specified information. Several toolkits combine both of the features described above. Initially, Data Capture Service the relevant data is highlighted with a mouse and the program generates a wrapper from this input. If the automatically generated result does not meet the specified requirements, the user has the additional possibility of implementing changes via an editor integrated within the toolkit. Whether frequent corrections are necessary or not depends, largely, on the underlying algorithms and the functional maturity of the toolkit.
