Abstract EN
The discordance between expressions interpretable by a natural language interface (NLI) system and those answerable by a knowledge base is a critical problem in the field of NLIs.
In order to solve this discordance problem, this paper proposes a method to translate natural language questions into formal queries that can be generated from a graph-based knowledge base.
The proposed method considers a subgraph of a knowledge base as a formal query.
Thus, all formal queries corresponding to a concept or a predicate in the knowledge base can be generated prior to query time and all possible natural language expressions corresponding to each formal query can also be collected in advance.
A natural language expression has a one-to-one mapping with a formal query.
Hence, a natural language question is translated into a formal query by matching the question with the most appropriate natural language expression.
If the confidence of this matching is not sufficiently high the proposed method rejects the question and does not answer it.
Multipredicate queries are processed by regarding them as a set of collected expressions.
The experimental results show that the proposed method thoroughly handles answerable questions from the knowledge base and rejects unanswerable ones effectively.
