A Semantic Retrieval Framework for Engineering Domain Knowledge
In this paper, we propose a knowledge retrieval framework based on semantically annotated engineering ontology generated from domain documents. Particularly, we propose a scheme for build relations between ontology and domain documents. First, we build anthologies in engineering domain. Next, we transform the keywords into domain ontology concepts, and then find the synonyms of these keywords which are used as real queries to directly input into the query system. The semantic-based knowledge search and retrieval is then performed by ontology mapping and comparison. Using the semantic network of ontology, this system not only can conduct keyword-based retrieval, but also can understand the queries and answer questions by fuzzy inference based on domain ontology.
