Description

In this project, the need for answer clustering and fusion in a user-interactive question answering (QA) system is identified and its user interface and enabling technology are presented. This function aims to help a user to efficiently browse all the answers and find the correct answer to a specific question by clustering answers into groups and providing a representative (fused) answer for each group. The clustering approach proposed includes a measurement of semantic similarity between answers and an incremental soft-moVMF algorithm. An answer fusion method is proposed, which uses concept vector and authority of data sources to extract the summary for the answers in each cluster.
