Semantic Parsing Using Construction Categorization

摘要

Semantic parsing which maps a natural language sentence into its meaning representation is considered in this paper. A novel approach which involves construction categorization is proposed. Constructions encode the correspondences of concept sequences and their meaning representations. They are categorized using the syntactic relations included in a predefined hierarchical concept base. The semantic parser construct the meaning representations for the input sentences based on these constructions. Evaluations on a benchmark dataset, Geo-Query, demonstrate that the proposed semantic parser provides favorable accuracy, as well as the generalization performance.
