The Research Of Information Retrieval Algorithm In Two Tickets Expert System

With the rapid development of social informatization, the sudden growth in volume of information resources, information resources heterogeneity and dynamic make full and effective use of these howhi geography information resources become more and more difficult, at the same time if you want to fully use the network resources and information knowledge, must with the aid of all kinds of information retrieval tools, makes the information retrieval become the key to the development of modern society informatization.In the implementation of the new institutionalism is working ticket, operation training and assessment of power plant, because of the power plant working ticket, the operation ticket management system is the guarantee of the electric power enterprise safety production run. This topic through according to the relevant theoretical knowledge of expert system, realized the working ticket security measures, operation operation project intellisense function of "two tickets" expert system. Through the application of expert system technology to improve the efficient learning and accurate operation of the plant personnel professional ability and skill.Through the analysis of work tasks and safety measures in power plant, operating tasks and operation program, the relation between correlation index method is proposed based on keywords. In the process of the establishment, the index by using safety measures or operation project, in accordance with the rules of "equipment + verb +status" index, task from the working ticket contains the keyword and its safety measures included in the associated relationship between keywords, the operation of the operating tasks included in the key words in the keyword and its operating projects to build relationship.In the process of indexing bidirectional maximum matching algorithm is adopted to improve the segmentation, the Lucene index technology and xml-based knowledge representation method, realized the working ticket, the operation ticket experts intellisense functionality, efficient display with the current task or operation taskcorresponding safety measures or action items such as content, effectively improve the efficiency of the electric power enterprise two votes training management work.
