Abstract
- Keyword search is a user-friendly way to query XML data,such that users do not need to understand the complex syntax of structured query languages and the complex structural information of the underlying XML data.However,existing semantics suffer from limited expressiveness, thus users cannot obtain desired information in many cases.We propose an entity-based semantics,namely ELCEA,to capture users'search intension by supporting additionally the semantics of "NOT".We verified the effectiveness of ELCEA by conducting rich experiment according to different metrics.
