Research On The Construction Of Knowledge Base Oriented To Aerospace Knowledge Management
PROCEEDINGS OF THE 18TH EUROPEAN CONFERENCE ON KNOWLEDGE MANAGEMENT (ECKM 2017), VOLS 1 AND 2(2017)
Abstract
Knowledge base can store, organize and process knowledge and also is the foundation to provide knowledge services. The construction and applications of knowledge base are essential for the knowledge-intensive enterprises to carry out knowledge management (KM), which can greatly boost the accumulation of knowledge assets and improve the innovation ability of researchers. Due to the difference in knowledge structure and actual demand, each enterprise has its own focus on the design of knowledge base. In consideration of the particularity of aerospace enterprises, this paper puts forward the thoughts of constructing knowledge base for aerospace enterprises from three levels: knowledge acquisition, knowledge processing and knowledge application. In order to achieve the effective acquisition and organization of the firsthand resources, different solutions are adopted to deal with the internal and external resources respectively. On the one hand, for the resources within enterprise, unified templates are used to extract the internal knowledge, which can promote the mutual conversion between tacit knowledge and explicit knowledge. On the other hand, to realize effective and accurate information collection, external resources are collected based on theme crawler. We further put forward the knowledge processing architecture, including text processing system and data processing system, to extract useful knowledge from the first-hand resources. The knowledge processing architecture is studied in this paper based on big data technologies, such as text similarity measure algorithm, word segmentation technology, feature engineering and machine learning, etc. Finally, this paper discusses the possible applications of knowledge base in the field of aerospace through the association mapping of text knowledge and data knowledge. This research may also provide a reference for other military enterprises to carry out the construction of knowledge base.
