Title: An experience using context in translation from system's requirements to conceptual model.

 Abstract:
In this paper we use context to simplify the translation from system's requirements expressed in natural language to conceptual model (Entity-Relationship Model). This translation is made by a tool called Designer Assistant. The goal of the system is to identify entities, attributes and relationships in natural language (Portuguese Language in our case). For example, post-graduation evaluation has several entities as notes, student, discipline, etc. The entity student has attributes as Department. However, in another application as university's organization, Department is an entity, because in this context it is a relevant information, i.e., the same object can be an attribute or an entity depending of the context. In our system, we distinguish the nature of such an attribute (contextual and contextualized knowledge respectively in the example above) in an application. The contextual information are stored in dictionaries with the words of Portuguese language.
