An Insight Into Relevance FeedbackAn Insight Into Relevance Feedback
Relevance Feedback is found to be one of the most powerful methods for improving Information Retrieval Systems
What are Search Engines?- But this is not efficient and effective enough.
So how does Relevance Feedback fit into search engines?
The Relevance Feedback is usually presented as a cycle of activity, know as an iteration relevance feedback.

The Techniques Behind Relevance The Techniques Behind Relevance FeedbackFeedback
Technique 1 – Traditional Relevance Feedback (RF)
Allows the user to express the information requirements
Technique 2 – Probabilistic Relevance Feedback (PRF)
Is one of the most advance Relevance Feedback techniques.

The Pros And Cons Of Relevance The Pros And Cons Of Relevance FeedbackFeedback
What kind of information is used for Relevance Feedback? - Usually it is a set of selected terms. But in any case it is never a whole document.
How this Information is selected from the documents?- Long documents usually cover several topics. It is very important to refine queries with the right information in order to get better results.
How Relevance Feedback information is used?- Relevance Feedback judgments are usually used to calculate a new refined query based on original query.

The Pros And Cons Of Relevance The Pros And Cons Of Relevance FeedbackFeedback
Disadvantages– Relevance Feedback requires terms and queries.– Has the right technique been selected for Relevance
Feedback?– Sometimes Relevance Feedback requires more input from the
user.
Advantages– The main strength of Relevance Feedback?– Users can focus on required relevant information.– Relevance Feedback is a good technique of specifying an
information need.– Users participate more in the search query.– Relevance Feedback is not limited to text and full text retrieval.

User Modeling
- the system seeks to adopt the behavior to individual needs.
- the system has a clear understanding of the users needs.
