The invention discloses
a domain knowledge base establishing method applied to a
discrete manufacturing industry production process. The
domain knowledge base establishing method comprises the following steps of S1,
text corpus management; S2, text preprocessing; S3, knowledge network retrieval; S4,
domain knowledge base construction. According to the method, the
domain knowledge base is established, and an effective
sorting algorithm is adopted, so that the retrieval results in the domain
knowledge base are sorted reasonably, and the retrieval results can be sorted according to relevancy, dates or sources and the like. When retrieval needs to be carried out by means of
empirical data such as a
word list, result arrangement is scientific and reasonable, and secondary retrieval can be carried out on retrieval results. And screening of multiple conditions is supported, and the average retrieval time is controlled within 0.5 second. Besides, the method supports retrieval of files of different formats such as PDF, word and excel, supports full-
text retrieval of resources, supports retrieval in a
word list and a
knowledge base, calls a
visualization tool and provides a
visualization display result.
