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.
