Query expansion strategies for laypeople-centred health information retrieval
This thesis proposes several query expansion methods using different sources and methodologies to identify which terms will be added to the original query, and proposes the MTI approach, proving that medical concepts related to the query are good terms for the query expansion. Expand

Term frequency with average term occurrences for textual information retrieval
A new TWS is proposed that is based on computing the average term occurrences of terms in documents and it also uses a discriminative approach based on the document centroid vector to remove less significant weights from the documents. Expand
