基于CRF的藏文地名识别技术研究
Research on Tibetan location Name Recognition Technology Under CRF
摘要
Abstract
Tibetan location name recognition is a problem that must be solved in Tibetan named entity recognition. By ana-lyzing the characteristics and recognition difficulties of Tibetan location names, this paper expounds that the characteris-tics of syllables, trigger words, location name follow-up words and case auxiliary words of Tibetan location names are applicable to location name recognition based on CRF model. Through experiments, the effectiveness of the six character-istics of this paper on Tibetan location name recognition is verified. The experimental results show that the accuracy rate, recall rate and F value of Tibetan location name recognition by this method reach 96.12%, 81.92% and 88.45%, respec-tively. Compared with the existing systems, the experimental results have achieved better results.关键词
