Web search users frequently modify their queries in hope of receiving better results. This process is referred to as ?Query Refor- mulation?. Previous research has mainly fo- cused on proposing query reformulations in the form of suggested queries for users. Some research has studied the problem of predicting whether the current query is a reformulation of the previous query or not. However, this work has been limited to bag-of-words models where the main signals being used are word overlap, character level edit distance and word level edit distance. In this work, we show that relying solely on surface level text sim- ilarity results in many false positives where queries with different intents yet similar top- ics are mistakenly predicted as query reformu- lations. We propose a new represe...
