ABSTRACT
We propose a simple yet effective approach to context sensitive synonym discovery for Web search queries based on co-click analysis; i.e., analyzing queries leading to clicking same documents. In addition to deriving word based synonyms, we also derive concept based synonyms with the help of query segmentation. Evaluation results show that this approach dramatically outperforms the thesaurus based synonym replacement method in keeping search intent, from accuracy of 40% to above 80%.

The Effect of Synonym Substitution on Search Results
HT '16: Proceedings of the 27th ACM Conference on Hypertext and Social MediaSynonyms or other semantic associations can be used in web search in query substitution to improve or augment the query to retrieve more relevant search results. The value of substitution depends on how well the synonyms preserve semantic meaning, as ...
Graded relevance ranking for synonym discovery
WWW '13 Companion: Proceedings of the 22nd International Conference on World Wide WebInterest in domain-specific search is steadfastly increasing, yielding a growing need for domain-specific synonym discovery. Existing synonym discovery methods perform poorly when faced with the realistic task of identifying a target term's synonyms ...
Synthesizing high utility suggestions for rare web search queries
SIGIR '11: Proceedings of the 34th international ACM SIGIR conference on Research and development in Information RetrievalSearch engines are continuously looking into methods to alleviate users' effort in finding desired information. For this, all major search engines employ query suggestions methods to facilitate effective query formulation and reformulation. Providing ...
