Abstract:
Information retrieval is concerned with
organizing and retrieving relevant documents
from a set of unstructured collections of
documents.In most collections, the same concept
may be referred to using different word.This issue
is known as synonymy which has an impact on the
recall of most information retrieval systems.The
problem can be eliminated by means of relevance
feedback where user judges the result of the initial
query, and system refines the query vector to
improve the recall.But in normal relevance
feedback, users have to give manual feedback
which is inflexible, so the proposed system uses
pseudo relevance feedback where top-k retrieved
documents are assumed to be relevance and query
is rewrite using Rocchio algorithm.Finally the
system analyzes with precision and recall of
information retrieval results
