Specific simulation field-based simulation information automatic-sequencing method

Abstract

The invention relates to a specific simulation field-based simulation information automatic-sequencing method, which comprises the following steps of: 1) defining a simulation factor Wf of a simulation field based on the characteristics of simulation resources, and defining important factors of a file and division based on the Wf; 2) adding a proper noun dictionary in the simulation field on the basis of a universal Chinese dictionary, and dividing documents to be sequenced into a plurality of related terms related to the sequencing according to the two dictionaries; 3) computing the relevance of each document to be sequenced; and 4) realizing the simulation field-based sequencing according to relevance computing results. The method of the invention has the characteristics of capacity of accurately retrieving information related to simulation application, simplicity and high efficiency, and is easy to operate and very suitable for currently-widespread distributed simulation application.

Description

technical field [0001] The invention relates to a method for sorting search information, in particular to a method for automatically sorting simulation information based on a specific field of simulation, and belongs to the field of computer modeling and simulation. Background technique [0002] The DoD of the US Department of Defense proposed the MSRR (Modeling & Simulation Resource Repository) plan when formulating the modeling and simulation master plan MSMP. Its purpose is to provide resource management, access , Browsing and retrieval tools, improve the reusability and sharing of modeling and simulation resources, and improve the efficiency and reliability of system development. The existing MSRR system in the United States is composed of nodes of 7 related agencies including DMSO, the Joint C4ISR Decision Support Center, the US Army, and the US Air Force, with models and simulation application resources as the core.

Problems solved by technology

[0003] For simulation resource users, they usually care about simulation information, documents, etc. related to the simulation field, but the general retrieval or sorting methods in search engines do not take into account the characteristics of their application fields. The general lexicon is used to realize word segmentation in the sorting process. It lacks proper nouns in the simulation field, and these nouns will be divided into common words, which do not meet the needs of the simulation field; on the other hand, the current sorting process The correlation with the simulation application is not considered, and the results returned to the user are mostly information that has nothing to do with the simulation field, which brings a lot of trouble to the simulation resource users

In addition, the vector space model (VSM) and the Boolean model in the correlation calculation method used in general sorting, first, require independence between words, and the related operations of vectors lack theoretical verification, and most of them are empirical formulas; It is difficult to establish a query expression method, the query results are out of order, and it is impossible to judge the relevance of related documents

It can be seen that, as a specific simulation application field, due to the variety of data storage methods, there are unique correlations such as levels and associations between resources, which are stored in distributed resource libraries in various forms such as files; and , with the development of simulation applications, the number and quantity of simulation resources are increasing, and the distributed environment of storage is becoming wider and wider. When the amount of information is large to a certain extent, the overall performance of the system has a significant decline. Simulation applications that increasingly emphasize response speed are extremely inconsistent, and it is difficult to meet the application requirements of simulation applications
