tailieunhanh - Automatic semantic annotation of sport news using knowledge base and extraction patterns

In this paper, we present a method for generating automatically semantic annotations of sport news items. It combines the results obtained through our continuous study of capturing different kinds of semantics which having from simple to more complex representation structure. | Journal of Science & Technology 128 (2018) 055-062 Automatic Semantic Annotation of Sport News Using Knowledge Base and Extraction Patterns Nguyen Quang Minh, Ngo Hong Son, Cao Tuan Dung Hanoi University of Science and Technology, No. 1, Dai Co Viet, Hai Ba Trung, Hanoi, Viet Nam Received: April 17, 2018; Accepted: June 29, 2018 Abstract The World Wide Web is currently one of the most popular platforms for publishing, disseminating and consuming news. However, the huge number of daily published news items brings new challenges for both readers and publishers of web news systems in the process of finding or arranging information. Aiming to change the representation of data in a machine-readable semantic annotation, the semantic web technology promise to address these obstacles. Therefore, finding the solution for creating annotation with valuable semantics is a key point in the development of our news aggregation system. In this paper, we present a method for generating automatically semantic annotations of sport news items. It combines the results obtained through our continuous study of capturing different kinds of semantics which having from simple to more complex representation structure. Our approach relies on the detection of named entities as the ontology instances using knowledge base on sport. The instances are matched with pre-defined patterns to extract semantics. Experiments on corpus of sport news validates the advantages of the proposed method and shows that semantic annotations are generated with high precision and coverage. Keywords: semantic annotation, semantic web, knowledge base, named entity recognition 1. Introduction and content management system with better accuracy when processing information [5]. * Thanks to the availability, accessibility, the Web is now one of the most popular platforms for publishing, disseminating and consuming news. It is a trend that news agencies and television channels use the Web as the main mean of .
