摘要 |
A method and system for improved query expansion in faceted search are provided. The method includes: receiving a search query; expanding the search query to obtain query expansion terms; and receiving a facet selection for the search query. A facet profile is retrieved in the form of collected important terms for the facet; and the query expansion terms are weighted by comparing them to the facet profile. The query expansion terms are re-ranked and the method includes executing the re-weighted query expansion terms whilst filtering for the facet.
