| 摘 要： | 基于本体的文本分类方法未考虑本体概念自身所含有的信息量及忽略本体推理功能。为此，以旅游领域为背景，提出一种基于领域本体的文本分类方法。该方法采用本体自身结构作为分类标准，通过计算特征项和本体概念间的语义关联度及结合本体的推理功能，将文本划分到合适的本体概念下作为概念的实例。实验结果证明，与传统方法相比，该方法的分类方法F1值至少提高8.7%。 |

| Abstract: | There are two shortcomings in the traditional Ontology-based Texts Classification(OTC) research,one is the Information Content(IC) that the concepts are not taken into account,the other is that they usually ignore the importance of the ontology reasoning abilities.This paper presents a tourism domain ontology based approach for texts classification,which solves the two problems mentioned above.This approach takes the structure of ontology as classification standard,which is realized by combining the semantic correlation degree of concepts and terms and the ontology reasoning abilities.The text is classified to the ontology concepts as the individuals.Experimental results show that this approach has at least 8.7% improvement over the traditional classification method on the measure of F1. |
| Keywords: | domain ontology text classification ontology concept Information Content(IC) reasoning semantic correlation |
