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.
