Development of an Engineering Knowledge Extraction Framework

摘要

In this paper, an engineering knowledge extraction framework was developed based on the ontology technologies. The engineering knowledge could be extracted from unstructured engineering documents. The ontology models of the target engineering knowledge are constructed by domain experts or automatic constructed with formal concept analysis in the first stage. The engineering document is then processed to mark the relevant semantic annotations with natural language process tool and domain dictionary. These annotations will be used to populate the ontology models with the concepts and properties in the ontology models. The populated ontology models can be then used for reasoning or other tasks requiring engineering knowledge.
