Knowledge Extraction from Source Code Based on Hidden Markov Model: Application to EPICAM

Large software systems evolve rapidly and these evolutions are usually integrated directly into source code without updating the conceptual model. As a consequence, implementation platforms evolve faster than business logic. Thus, when extracting knowledge to enrich or build an ontology, business logic is not always a complete data source. To solve this problem, some authors have suggested to adopt an ontology learning approach in order to extract knowledge from the source code. In this paper, we show how to realize this task using Hidden Markov Models. experiments on EPICAM, a tuberculosis surveillance system shows the relevance of this approach.
