The main focus is to add a new dimension to Internet-Searching and that is to apply semantic aspects towards it. An essential requirement of this work is one has to recognize the difference between what a user might say or do and what she or he actually meant or intended. In more simple words, “the search must be what user wish, not what he/she typesâ€. Quering the search engine for any particular topic would retrieve the results from the internet and presented to the web users. Since there are large number of web pages on the internet and thus result obtained are also vast. User gets more than enough web links as a result produced by search engine and wastes their precious time in navigating through unwanted links, searching the needed one. The main reason for this is that the Search Engine do the indexing of the pages on the basis of text entered by user. In order to overcome this shortcoming we need to implement a method that will allow the user to find the relevant words, starting from the few words that they may actually know [5].In other words, we need to focus on the semantic of words entered by user and for this purpose a new approach that is based on some algorithms which considers semantic aspects should be included. One of such technique for the semantic analysis is the Latent Semantic analysis and Probabilistic Latent Semantic Analysis.
