Research on accessing databases using natural language
usually utilizes an intermediate logical form for the
mapping process from natural languages to database query
languages. However, there are still efforts to be
accomplished to bridge the gap between natural language
constructs and database schemas. In this paper, we present
a translation scheme for transforming natural language
queries into relational algebra through ORM (Object Role
Modeling) representations. This approach employs a
logical form to represent the natural language queries. The
logical form has the merits that it can be mapped from
natural language constructs by referring to the conceptual
schema modeled by ORM.
