A Semi-automated generation of Entity-Relationship Diagram based on Morphosyntactic Tagging from the Requirements Written in a Serbian Natural Language

An Entity-Relationship (E-R) diagram is a graphical representation of interest in a specific domain of knowledge about any information system. It is a data modeling technique that can help defining business processes and plays a central role in software engineering process. Extracting conceptual models from natural language requirements can help identify dependencies, redundancies, and conflicts between requirements generated from lengthy textual specifications. The automatic generation of different software diagram from natural language requirements such as English is highly challenging, with advancements in artificial intelligence. In this paper, a semi-automated approach for the design of E-R model from the short requirements written in a Serbian natural language using morphological analysis is presented. Presented rules are heuristics and were founded suitable for conceptual model creation in the phase of requirements analysis. At the end, examples obtained by using basic learning resources are presented.
