KBQA: Learning Question Answering over QA Corpora and Knowledge Bases
Table 11: Results of hybrid systems on QALD-3 over DBpedia.
['System', 'R', 'R*', 'P', 'P*']
Results for hybrid systems Even for a dataset that the BFQ is not a majority (e.g. WEBQUESTIONS, QALD-3), KBQA contributes by being an excellent component for hybrid QA systems. We build the hybrid system by: first, the user question is first fed into KBQA. If KBQA gives no reply, which means the question is very likely to be a non-BFQ, we fed the question into the baseline system. The performances of all baseline systems significantly improve when working with KBQA. The results verify the effectiveness of KBQA for a dataset that the BFQ is not a majority.
