A Method for Acquiring Experiential Engineering Knowledge from Online Engineering Forums
Question and answer (Q&A) is the most primitive and common way of knowledge exchange. There is a lot of empirical knowledge accumulated in the Q&A record of online engineering forums. In order to acquire experiential engineering knowledge from the Q&A record, first an ontology of experiential engineering knowledge is constructed by referring to authoritative and structured domain text, whereby a formal conceptualization of a specific engineering field is obtained. In view of the relatively lower quality of empirical Q&A compared with authoritative knowledge source, the quality of online Q&A in the field of computer-aided engineering is evaluated by referring to the relevant methods in the quality evaluation of community Q&A. Finally, by selecting high-quality Q&A and express it as ontology concepts and attributes, the acquisition of experiential engineering knowledge is achieved.
