Since their inception, entity relationship models have played a central role in systems speci�cation, analysis and development. They have become an important part of several development methodologies and standards such as SSADM. Obtaining entity relationship models, can however, be a lengthy and time consuming task for all but the very smallest of speci�cations. This paper describes a semi-automatic approach for obtaining entity relationship models from natural language speci�cations. The approach begins by using natural language analysis techniques to translate sentences to a meaning representation language called logical form language. The logical forms of the sentences are used as a basis for identifying the entities and relationships. Heuristics are then used to suggest suitable degrees for the identi�ed relationships. This paper describes and illustrates the main phases of the approach and presents a summary of the results obtained when it is applied to a case study.
