Research On ERP Component Retrieval Technologies Based On Faceted Classification Schema

In order to improve the efficiency of ERP system development, Shorten the ERP software development cycle, Reduce the cost of the corresponding, We have established the field of ERP professional ERP component library ERP. In the ERP component library, ERP components of the ERP component classification and retrieval is one of the most basic functions,Because the efficient and effective retrieval mechanism can significantly reduce the cost of ERP software, At present domestic and international classification systems based on facets of the ERP component retrieval method is the more common large software developers and adequate attention to the classification of search methods, Because the method can adapt to large-scale ERP components are managed, can fundamentally improve the retrieval efficiency, enabling users to quickly find what you want ERP components. With the moment of faceted classification retrieval method can retrieve all taking into account price, quality and complexity of the search, so that to achieve the best balance between the three results, Therefore, based on faceted classification-based component retrieval techniques can be software reuse community attaches great importance to and received unanimous praise.In this paper, a number of related ERP component retrieval concept is a simple introduction, and examples of domestic and foreign research institutions and academic research in this field the status quo, through the analysis of key technologies, pointed out that the existence of certain deficiencies in the current and proposed improvements, the final adoption of the feasibility of experimental verification.This paper is divided into three main parts, the first part of the first introduced some basic concepts, and related key technologies, and highlighted some of the concept of faceted classification and its main key technologies for the core part of the paper pave the wayThe second part of the paper, according to the ERP component retrieval has its own characteristics, with the thinking of the tree matching model combining the ERP components into a search tree model matching, relaxation matching based on the tree level introduced the six kinds of commonly used tree matching model, and then match these six kinds of cost and the corresponding algorithm is the focus of analysis and draw the relevant conclusions, Finally, several models to cover the above-mentioned algorithms and proposed improvements to the recall rate and precision rate of all have a great deal of improvement and has great practical value.The third part of the paper is also part of the paper is verified, in order to verify that the paper presents an algorithm that can be sexual, in the. NET development environment to achieve a retrieval system prototype, and highlights a number of core modules of the basic functions, while giving out the search page.
