An Empirical Study On The Construction Method Of Chinese Consumer Health Vocabularies

In the pase decades, medical informatics developed rapidly.At the very beginning, the accomplishment of these researches is the establishment of some system which meets the information needs of Medical researchers and makes full use of medical information.At the present time, with the alteration from "Doctor-centered" pattern to "Patient-centered" pattern,the attention of people is also transformed to Consumers of medical services'information demand.Majority of these consumers of medical information are non-medical professionals.American researcher found that it is the key element, which are the differences between the words that lay person used and professional medical terms, that leads the result of retrieve failed. It's just under the background as this make the Consumer Health Informatics work out. At present in USA, it has been considered as one important embranchment of Medical Informatics, which has been researched emphasis on the related problems that in usage of medical information in unprofessional consumers. Consumer Health Informatics, which is the bridge between unprofessional medical consumer words and professional medical terms, has been thought highly of by authorities. As a result of this, Consumer Health Informatics has been a new hot spot. English Consumer Health vocabulary has become some scale and participated in many web sites.It is later in our country to research Consumer Health Informatics. In 2006, it is the first time that academicians in our country translated it into Consumer Sanitation Informatics. Nowadays, we focus on the estimation and control of quality, which is information that we support to the unprofessional medical consumers under the internet situation. As a result of this, we do not put our attention to advance the result of retrieving medical information.The form of Chinese Consumer Health Vocabulary, on one side, can raise the speed and usage affiance of retrieving by unprofessional medical consumer; On the other side, it can support some theories and practice basis of medical information retrieve service and the development of consumer health informatics in some degree. At the same time, it also makes an passive impact on the side that improve the part of library information consultation which is the central part to consumer health informatics.In this issue, we regard the behavior of unprofessional medical consumers as the research view, the difference between the unprofessional medical consumer retrieve words and medical terms as the research origin, the theory of information retrieve as the research basis, combine the foundation principle of Only-search Vocabulary and English consumer health vocabulary, regard the related result of chinese language segmentation as the technical support, based on the semantic mapping between unprofessional medical consumer words and professional medical terms,constituting the Chinese consumer health vocabulary, researching the resolve method of effective ways of unprofessional medical consumer retrieving unprofessional words. On the same time, we also put forward the forming project of Chinese consumer health vocabulary. Through practicing the feasibility of it, supporting reference basis of advancing the retrieve result and the affiance of utilizing medical information. It preserve crucial purport of theory and practice.In this paper, the main research contents are as follows:1.Design the Construction Method of chinese consumer health vocabulariesIn this paper,combined with Theory,Establishment of the principle and correlation technique of Only-search Vocabulary ,reference CHVs design projects of Harvard University and U.S. National Library of Medicine,the Construction Method of chinese consumer health vocabularies was proposed.2. Form Non-professional medical dictionaryThe effect of Chinese word-cutting is a essential element of the quality of weaving chinese consumer health vocabularies。Especially, medical concepts of oral expression of lay persons are very exuberance, which is the bark for distinguishing the unprofessional medical words of chinese language segmentation system. For satisfied individual need of customers better, ICTCLAS chinese language segmentation system supports the function that import the dictionary that customer needed to chinese language segmentation system。In our research, in order to ameliorate the efficiency of chinese language segmentation systemof distinguishing the lay person expression, we collect the word which are mincing by chinese language segmentation system。By reorganizing and distinguishing, we sort out those words, which preserve explicit medical concept, into dictionary. Thus, we named this dictionary Non-professional medical dictionary.We optimize the effect of chinese language segmentation by import the Non-professional medical dictionary into chinese language segmentation, which can amend the situation that non- professional user medical terms are cut falsely.3. Empirical Study on the Construction Method of chinese consumer health vocabularies and Non-professional medical dictionaryTake baidu for instance, which is the maximal search engines with Chinese in the whole world. We capture it based on the"ask and answer"interactive sharing flat roof-questions of lay person of the plate of"medical treatment/disease", which is the resource we used to constitute the corpus of the lay persons. We did research and approve to the forming project, which is exactly the fundamental part we want to enhance the service for the Chinese Medical Information Retrieval for the lay persons.After studying,we can arrive at the following conclusions:1.There is definitely exist discrepancies between the non- professional user medical terms and professional medical terms. Those discrepancies produce many barks for lay persons when they want to search for medical information, understand medical concept and communicate with professional workers. consumer health vocabularies are exactly right for this problem.2.The foundation of English and Chinese consumer health vocabularies is taking sharp. The vocabulary and application fields are continuously enlarging. Through our research we found that there is feasibility for forming the chinese consumer health vocabularies。Nevertheless, it takes more research to make this system more symmetrical, precise and perfect based on theory and practice.3.The differences between the English and Chinese is essential element for chinese language segmentation technology to be the fundamental one for instituting the chinese consumer health vocabularies. At the present time, it's very numbered for distinguishing unprofessional medical word in chinese language segmentation system, which is one of the reason that will affect the sophistication of chinese consumer health vocabularies. As we proved that it is one way to advance the effect of language segmentation by induce the unprofessional medical related dictionary into chinese language segmentation system.
