Ontology Construction And Semantic Retrieval Based On Online Medical Comment Data

With the development of Internet and the popularization of network facilities,it has become a common thing to enjoy information services and comment online.Network platforms are springing up,and a large number of online comment are accumulated on various information platforms.Mining online comment has always been the research focus in various fields.Aiming at the online comment texts on these platforms,many scholars in the field have introduced ontology-related theories and methods for mining,and have achieved many research results.However,how to use these information effectively,and how to search online comment information in deep semantic level is another big problem at present.There are has two main meanings using ontology to retrieve online medical comment at semantic level.On the one hand,the potential users of the online medical service platform can understand the quality of the platform through semantic retrieval of the online comment text,even understand the attributes of the corresponding doctors and hospitals,as the information reference of whether they choose the platform,as well as the Reference standards about the decision of whether they enjoy the service of the platform or the resident doctors of the platform.On the other hand,mining online medical comment at semantic level can provide the platform operators with structured data sources,provide data reference for platform improvement and development strategy formulation,and also serve as one of the indicators for online medical service platforms to assess and evaluate their resident medical doctors.Firstly,the paper introduces the distribution of online comment on the Internet,the introduction of ontology into online comment and the application in biomedical field,and then makes a review on the research of online comment mining and ontology based semantic retrieval at home and abroad.Secondly,this paper introduces the relevant theories,construction methods,construction tools and description language of ontology,as well as the related theories of semantics retrieval technology and semantic retrieval system are explained.Thirdly,the paper also considerates several domestic online medical service platforms,selects the two main platforms to crawl the relevant online comment texts,and processes the original texts of online comment crawled,such as sorting and framework semantic annotation,and stores them in the database.Then,the paper constructs the ontology model of Online medical comment,relates the database to map concepts,and completes the integration and filling of ontology.What's more,this paper designs a semantic retrieval system based on the ontology of online medical comment by using relevant tools and development languages,and demonstrates the retrieval function and evaluates the retrieval function.Lastly,summarizing the work done in the paper,analyzing the shortcomings of the paper,and putting forward the next improvement focus and research direction.
