Multi-Module System for Open Domain Chinese Question Answering over Knowledge BaseYiying Yang, Xiahui He, Kaijie Zhou et al.
For the task of open domain Knowledge Based Question Answering in CCKS2019, we propose a method combining information retrieval and semantic parsing. This multi-module system extracts the topic entity and the most related relation predicate from a question and transforms it into a Sparql query statement. Our method obtained the F1 score of 70.45% on the test data.
