چکیده

This paper reports on the participation of the system namely “sJanta” at NII Testbeds and Community for Information Access Research Project 11 (NTCIR-11) Question Answering (QA)-Lab English sub-task. sJanta is a modular question answering system that can answer multiple choice questions given in English natural language. We use English Wikipedia as knowledge-base. At first we retrieved Wikipedia articles for the question. After finding the Wikipedia articles, we retrieved question specific passages. Then, we did dependency parsing, question context analysis and semantic similarity matching to score the answer choices. Finally, the best score-generating answer choice was picked as the answer. Although sJanta applied very simple technique in answering the questions, performance of the system is quite promising.
