1.Introduction.

Every organization  accumulates huge volumes of data from  a variety of sources on a daily basis. Data Mining is an iterative process of creating predictive and descriptive models, by uncovering previously unknown trends and patterns in vast amounts of data from across the enterprise, in order to support decision making. Text mining applies the same analysis techniques to text-based documents. The knowledge gleaned from data and text mining can be used to fuel strategic decision making. During last decade a number of knowledge discovery systems were created which detect structure hidden in data in form of functional dependencies between attributes and formulate them as mathematical equations or other symbolic rules. One of most developed systems which can discover very complex and diverse equations, solves systematically problems of data error analysis and evaluates statistical significance of obtained results is designed to discovers empirical laws in data in form of functional programs constructed from standard and user-defined functional primitives. Although the systems which discover numerical dependencies in data use diverse knowledge representation formalisms and search methods they face the same set of difficulties inherent to their approach. Traditional document and text management tools are inadequate to meet the utilities. Document management systems work well with homogeneous collections of documents but not with the heterogeneous mix that knowledge workers face every day.

If you are not already using headings on your website, now it is the time to start using them. Why? They will help you improve your website ranking in the search engine. The heading tags are HTML tags that are used to hierarchically organize the design and the content of a web page. These “H” tags range from H1 to H6 (the short form of Heading 1 – most important, to Heading 6, the least important, and define text in header font and prominence. In established site, tags are used to give the page structure of “what” the the page is about. It suggests both to human visitors and search engines the ontology of the page and how important a page section is based on the section heading type, H1 or H6. By doing this, visitors can understand the pages in better manner and website can boost in search engines result.
There are six levels of heading tags in HTML: H1, H2, H3, H4, H5, H6. The H1 tag heading should contain the most important section of the site and often it is a good idea to match the page title tag (title of the website page). The H2 tag is next important tag which is used for subheading. This tag is lesser important than the H1 tag, but still of high importance for search engines. The H2 tag can support H1 tag by repeating the most important keyword in both H1 and H2. While the H3 tag is for titles of different sections in content, it is not recommend to be used as the title of page. The H4, H5, and H6 tags are used for sub-heading to the content section or the information in the footer.
The H1 tag is the most important of the six “H” tags in SEO strategy. It should be placed at the top of content so that visitors can easily understand what the content of the page is about.. This heading should accurately and briefly describes the content of the web page that follows and it should contain your main important keyword. Do not overuse it, meaning do not use the H1 more than once on the same web page The search engine robots will visits your website pages and analyze their content. While trying to determine the main theme (please read, “keyword”) of a specific web page, The robots will look for important tags such as the H1 and other heading tags that are present to find the content. If there is a semantic relationship between the page title, the H1 and H2 tags and the body text content, chances are that the robots will properly identify the main theme of the page and will give it a boost in search results related to that keyword.
Search engine robots are “crawling” as many web pages as they can find on your website, and for each page they will try to figure out which keywords and key phrases those pages are relevant for. To rank your website higher in search engines, it is helpful to consider place the most important keywords into various levels of header tags.

SEO or search engine optimization is one part of the growing search engine marketing (SEM) methods that purely involves the use of several techniques in order to gain traffic via achieving the highest ranking in any search engine, may it be Yahoo!, Google, or MSN. These techniques usually involves changes within the website (commonly called by consultants as On-Page SEO) as well as techniques used outside the website (or Off-Page SEO). One particular technique used in SEO, apparently categorized as an Off-Page SEO technique, makes use of web directories to achieve higher results in search engines. A web directory or link directory is a directory on the World Wide Web. It specializes in linking to other web sites and categorizing those links. Human-edited directories are often targeted by SEOs on the basis that links from reputable sources will improve rankings in the major search engines. According to SEO Philippines consultants, many human-edited directories, including the Open Directory Project (or DMOZ) and World Wide Web Virtual Library, are edited by volunteers, who are often experts in particular categories. Top web directories used by SEO specialists or consultants today include:

Open Directory Project (or DMOZ) World Wide Web Virtual Library Yahoo! Directory JoeAnt Best of the Web Directory
Open Directory Project or DMOZ
The Open Directory Project (ODP), also known as Dmoz (from directory.mozilla.org, its original domain name), is a multilingual open content directory of World Wide Web links owned by Netscape that is constructed and maintained by a community of volunteer editors. ODP uses a hierarchical ontology scheme for organizing site listings. Listings on a similar topic are grouped into categories, which can then include smaller categories. There are, however, several controversies surrounding the use of these websites. There have long been allegations that volunteer ODP editors give favorable treatment to their own websites while concomitantly thwarting the good faith efforts of their competition.
Such allegations are fielded by ODP’s staff and meta editors, who have the authority to take disciplinary action against volunteer editors who are suspected of engaging in abusive editing practices. In 2003, ODP introduced a new Public Abuse Report System that allows members of the general public to report and track allegations of abusive editor conduct using an online form.
World Wide Web Virtual Library The World Wide Web Virtual Library was the first index of content on the World Wide Web and still operates as a directory of e-texts and information sources on the web. It was started by Tim Berners-Lee, the creator of HTML and the Web itself, in 1991 at CERN in Geneva. Unlike commercial index sites, it is run by a loose confederation of volunteers, who compile pages of key links for particular areas in which they are expert. It is sometimes informally referred to as the “WWWVL”, the “Virtual Library” or just “the VL”. The central affairs of the Virtual Library are co-ordinated by an elected Council. A central index (the ‘Catalog’) is maintained and joint services provided by the Council on behalf of the association. Yahoo! Directory
The Yahoo! Directory is a web directory which rivals the Open Directory Project in size. The directory was Yahoo!’s first offering. When Yahoo! changed to crawler-based listings for its main results in October 2002, the human-edited directory’s significance dropped, but it is still being updated. The Yahoo! Directory offers two options for suggesting websites for possible listing: “Standard”, which is free, and a paid submission process that offers expedited review. Payment is required when suggesting a commercial site. JoeAnt JoeAnt is a human edited directory offering “to provide a directory of quality sites for Internet users”. Created by a group of a dozen former Go.com (Disney) volunteer Go Guides, JoeAnt was born of the desire to provide relevant results in a wide variety of topics, and seeks to work by forming a ‘community’ of editors where anyone interested can join in. Launched on May 24, 2001, JoeAnt has grown into a big directory with a large editor list.
The site was re-launched in August 2002 following an extensive site rebuild that recreated the back-end to enable the directory to be indexed by search engine spiders, while adding several new tools for editors, and improving the performance of the search engine. According to SEO Philippines consultants, additions can be made in two ways. Listings can be paid for by website owners, with no guarantee of being listed. Listings can also be added by volunteer editors. Volunteer editors are registered automatically and do not have to go through a review process. The sites they submit go to a higher-level editor regardless of topic. This allows the submitter to get a quick review of the site without the likelihood that the reviewer is a competitor. Best of the Web Directory Best of the Web Directory is a commercial web directory providing websites categorized topically and regionally. Headquartered in Uniondale, New York, BOTW also maintains offices in Orange, Texas, Rocklin, California, Studio City, California and Highland Beach, Florida. In 2002 BOTW transformed into a general web directory, aiming to provide users with a spam-free categorization of websites. The company employs a team of paid editors that search the web for sites with original content, whilst considering user-friendliness and web standards. BOTW offers listings for both commercial and non-commercial sites, and places each site that meet their editorial guidelines in its most relevant topical and/or regional category. Due to the manual editorial involved in the listing process, many search engines view listings in “quality directories” as a valued citation. According to SEO Philippines consultants, submitting their sites to directories can increase their search engine listings. For more information visit our website at http://www.myoptimind.com.
