Building query graphs from natural language questions is an important step in
complex question answering over knowledge graph (Complex KGQA). In general, a
question can be correctly answered if its query graph is built correctly and
the right answer is then retrieved by issuing the query graph against the KG.
Therefore, this paper focuses on query graph generation from natural language
questions. Existing approaches for query graph generation ignore the semantic
structure of a question, resulting in a large number …
