A Survey on Effective Relevance Feedback Methods for Web Information Retrieval

In current scenario, information retrieval is the tedious process due to its vast collection of interconnected hyperlinked documents available in the web. In general, there are several tools and search engines are available to retrieve information’s from web repositories. According to the users query, the search engines are retrieving hundreds and thousands of web links. Several contents are not useful and irrelevant to the user query.

This leads to several information retrieval problems. In order to improve the retrieval efficiency, RF (Relevance Feedback) methods are introduced. The relevance feedbacks are categorized into three types, one is implicit, explicit and pseudo feedback.
