Patsakorn Singto, Anirach Mingkhwan · Journal of Advanced Management Science · 2013
Nowadays, there are a lot of IT Careers (ITC) which are not stored in a hierarchical structure of ITC specification and matching search based on keyword have widely use search which cannot acquire satisfactory search results. The essential reason is that traditional ITC search lacks semantic. In this paper, we propose searching ITC concepts based on ontology which is associated specification with semantic annotation. IT Careers Ontology (ITCO) defined structure consists of three main parts: IT Career Category, IT Skill and IT Education which are described with announcing the recruitment on web jobs ads that are instances of a models. The experimental results show that semantic search ITC can overcome limitations of search by comparison with traditional keyword search mode, and achieve higher recall ration and precision ratio. Index Term—semantic search, ontology, OWL-QL, IT careers.
