Abstract
Methods and apparatus determine equivalent descriptions for an information need. In one implementation, if adjacent entries in a query log contain common terms, the uncommon terms are identified as a candidate pair. The candidate pairs are assigned a score based on their frequency of occurrence, and pairs having a score exceeding a defined threshold are determined to be synonyms.
