FLL: Local Alignments based Approach for NTCIR-10 RITE-2.

要旨

This paper describes the textual entailment system of FLL for RITE-2 task in NTCIR-10. Our system is based on a set of local alignments conducted on different linguistic units, such as word, Japanese base phrase, numerical expression, Named Entity, and sentence. Our system uses features obtained from local alignments’ results. We applied our system to Japanese BC task and Japanese MC task at formal run, and Japanese UnitTest task at unofficial run. The performance of our system for BC task and MC task outperformed baseline, and the result of UnitTest achieved the best performance.
