SINA: Semantically INterpreting user query towards question-Answering

  • screenshot

Knowledge bases published on the Web of Data can be used to answer challenging questions about a wide range of topics. They usually offer a SPARQL endpoint, which can be queried by the user. However, a novice user needs to acquire both knowledge about the underlying ontology and proficiency in formulating SPARQL queries in order to actually formulate a SPARQL query. In this project, we are working on constructing SPARQL queries based on user-supplied keywords. As a result ordinary users are empowered to formulate relatively expressive queries without knowledge of SPARQL and the underlying ontology structure.

Here is a screencast explaining the functionality and usage of SINA.
