ABSTRACT
Document recommendation system is useful to find the right results immediately without adding filters manually or clicking through multiple navigation menus. This paper first surveys various just in time retrieval agent and then reports several term weighting scheme. Just in time retrieval agent proactively provides valuable information without any explicit search. Term weighting enriches the retrieval efficiency. Previously recommendation was based on the word frequency, but to make the recommendation relevant, coverage of main topic becomes important. The comparative study among them will help in selecting the appropriate method.
