When answering natural language questions over knowledge bases (KBs), different question components and KB aspects play different roles.
We investigate entity linking in the context of a question answering task and present a jointly optimized neural architecture for entity mention detection and entity disambiguation that models the surrounding context on different levels of granularity.

However, one critical problem is that current approaches only get high accuracy for questions whose relations have been seen in the training data.
In this paper, we propose a novel knowledge-aware dialogue generation model (called TransDG), which transfers question representation and knowledge matching abilities from knowledge base question answering (KBQA) task to facilitate the utterance understanding and factual knowledge selection for dialogue generation.
The paper presents RuBQ, the first Russian knowledge base question answering (KBQA) dataset.
