Abstract:Based on the query logs and news data provided by Sogou Lab, this paper studies judging queries involving implicit temporal intent and recognizing the implicit temporal attribute of these queries,and it also constructs the retrieval model of implicit temporal intent of queries.The experiment results show that the precision of temporal attributes recognition is 85% and the retrieval model can improve the effectiveness of ranking results.
Key wordsImplicit temporal intent query    Implicit temporal intent    Temporal attribute    Retrieval model
