Research on the Development Method of the Semantic Web Application Based on AllegroGraph

With the continuous development of semantic web technology, semantic web applications are getting more and more attention. However, the research on semantic web applications at home and abroad is still in the theoretical stage, lacking the specific methods of semantic web application development. Moreover, there are few semantic web products for users. In response to this problem, the advantages of AllegroGraph in semantic data storage and query as well as in the semantic web application development are introduced. Then the development framework of the semantic web application based on AllegroGraph and its implementation method are given. Specifically, taking information retrieval as an example, the construction process of the data layer, the logic layer and the presentation layer are described in detail. The experimental results show that the information retrieval method based on semantic, compared with that based on keyword, has a significant improvement in the recall rate and precision rate, which lays a foundation for the application of semantic web products in enterprises to a certain extent.
