Bi-gram based Query Expansion Technique for Amharic Information Retrieval System

Abey Bruck, Tulu Tilahun
2015 International Journal of Information Engineering and Electronic Business  
Bi-gram technique uses the underling theory of expanding a query; using terms that appear adjacent to a query term frequently.  ...  Query expansion methods outperform in differentiating the various meanings of a polysemous term and find synonymous terms for reformulating users' query.  ...  Local automatic analysis can also be referred as relevance feedback, because it considers documents retrieved using users' original query as relevant.  ...
