Query expansion by inflection and decompounding (English)
Abstract [en]

The purpose of this thesis is to examine the performance of queries that are expanded by 1 inflections, 2 compound splitting and 3 inflections and compound splitting combined. For compound splitting, the morphological analyser SWETWOL was used. Queries were executed in the Query Performance Analyser, QPA, containing the InQuery system. Query terms were selected from 29 topics, all of whom containing at least one compound word. Both the queries and the documents were in Swedish. The results of the study indicates that the use of inflections have more impact on the retrieval performance than compound splitting. Overall, we found that the query expansion by inflection and compound splitting are useful strategies.
