RESEARCH ON AUTOMATIC COMPUTATIONAL MODEL OF TECHNOLOGY LIFE CYCLE BASED ON DOMAIN ONTOLOGY

摘要

With low-level automation and inexact technical classification, traditional technology life cycle computational model cannot generate dynamic technology life cycle. After summarizing the existing technology life cycle construction methods, this paper proposes a new evaluation model of technology life cycle based on domain ontology. First, this model constructs a domain ontology with domain vocabularies and natural language processing methods which could effectively define and extract technical words. Next, through article data, a three-layer ontology structure can be built. Then, the technical words of each article are labeled by semantic tagging, and the relationship between technical words has also been redefined. By this means, we can conveniently evaluate technology life cycle by statistics and analysis of the development trend of articles. At last, this paper achieves an automatic computational model of dynamic technology life cycle. The empirical study on AI and graphene fields shows the effectiveness of the model.
