Natural language interpretations for heterogeneous database access
Ho-Dong Lee, Jong Cheol Park · 2002
In order to query into diverse types of databases and to integrate the resulting information, dispersed throughout the network in a specific domain, we must address complex problems due primarily to heterogeneity of the involved databases. In this paper, we propose to model access to heterogeneous databases, by interpreting natural language queries into queries in formal languages such as SQL, OQL, and CPL by accounting for various language-specific constructions including join relations, path expressions, and object bindings with domain resources and a common lexicon, in a combinatory categorial grammar framework.
