The described systems and methods are directed to ranking web sites or web pages or documents, on internet or intranet, when two or more search words are used to search for web sites or web pages or documents on internet or intranet. Rank of web sites or web pages or documents will be based on the positional correlation matrix created using paired positional correlation of the search words. In order to calculate paired positional correlation; search words will be indexed within a web site or web page or document based on the position of the sentences, in which they occur, and their position within the sentences. It is possible that contents of web sites or web pages or documents are in tabular form instead of textual/descriptive form, in that case, either columns or rows or any other order of table cells can be considered as equivalent to a sentence and can be used to index the search words. Positional correlation matrix can be a, but not limited to, two dimensional representation of the paired positional correlation of the search words. Rank of the web site or web page or document will be based on relevance score, which will, at least in part, be based on search words cumulative paired positional correlation taken from positional correlation matrix. Performance of the system can be improved by calculating positional correlation matrix for web sites or web pages or documents, in advance, based on the key words. Key words can be referred to as the words that web site or web page or document claims to be the best source of information. Relevance score, of the web site or web page or document, can then be readily calculated by picking the paired positional correlation of the search words from the positional correlation matrix of key words, calculated earlier. |
