Query Expansion for Sentence Retrieval Using Pseudo Relevance Feedback and Word Embedding
CLEF, pp. 97-103, 2017.
This study investigates the use of query expansion (QE) methods in sentence retrieval for non-factoid queries to address the query-document term mismatch problem. Two alternative QE approaches: i) pseudo relevance feedback (PRF), using Robertson term selection, and ii) word embeddings (WE) of query words, are explored. Experiments are car...More
