【摘要】： 隨著INTERNET和信息技術(shù)的飛速發(fā)展,以及科研工作者對信息流通快速、高效的要求越來越強烈,電子資源開始成為圖書館文獻(xiàn)資源的重要組成部分。高校圖書館每年花費大量的經(jīng)費購置電子資源,因此迫切需要對電子資源進(jìn)行科學(xué)客觀的評價,從而調(diào)整購置決策,在有限的經(jīng)費條件下,合理配置資源,實現(xiàn)電子資源的最優(yōu)化配置。電子期刊數(shù)據(jù)庫作為電子資源的重中之重,由于其自身的特點以及讀者對其要求的特殊性,使得電子期刊數(shù)據(jù)庫的評價成為高校圖書館迫切需要解決的問題。 本文采用模糊綜合評價方法,對電子期刊數(shù)據(jù)庫進(jìn)行評價,并通過實證研究,探求一個科學(xué)合理的電子期刊數(shù)據(jù)庫評價體系。 本文主要從以下幾個方面進(jìn)行研究: (1)將復(fù)雜的電子期刊數(shù)據(jù)庫評價問題劃分為包含5個一級指標(biāo),30個二級指標(biāo)的評價體系,指標(biāo)既概括又全面,同時易于獲得,從而將復(fù)雜問題簡單化。 (2)采用層次分析方法賦予各指標(biāo)權(quán)重。在權(quán)重分析過程中,考慮專家的權(quán)重合理分配問題,采用直接賦權(quán)法確定專家先驗權(quán)重,采用系統(tǒng)聚類方法確定后驗權(quán)重,采用凸組合獲得較為客觀的專家綜合權(quán)重。并運用群組決策方法,對多專家判斷按照加權(quán)綜合向量排序法整合,得出最終的各因素綜合排序向量。 (3)采用模糊綜合評價方法,將評價體系的定性定量指標(biāo)統(tǒng)一規(guī)劃,解決了電子期刊數(shù)據(jù)庫評價體系指標(biāo)邊界模糊、類型、量綱不同的問題。通過評價電子期刊數(shù)據(jù)庫的整體等級,及各個準(zhǔn)則層指標(biāo)的等級,各方案層二級指標(biāo)的等級,確定電子期刊數(shù)據(jù)庫的購置決策。其中評價因素權(quán)向量即通過上述群組AHP獲得的綜合排序向量。同時,采用加權(quán)平均的方法分析評價結(jié)果,使評價結(jié)論更加科學(xué)合理。 (4)利用實證研究,驗證本文的評價體系的合理性和可行性。 最后,對本文電子期刊數(shù)據(jù)庫評價體系的研究進(jìn)行了總結(jié),并對下一步的工作進(jìn)行了展望。
[Abstract]:With the rapid development of INTERNET and information technology, the demand of researchers for rapid and efficient information flow is becoming stronger and stronger. Electronic resources began to become an important part of library literature resources. College libraries spend a lot of money to purchase electronic resources every year, so it is urgent to carry out scientific and objective evaluation of electronic resources. In order to adjust the purchasing decision and allocate the resources reasonably under the condition of limited funds, the electronic periodical database is the most important of the electronic resources to realize the optimal allocation of electronic resources. Because of its own characteristics and the particularity of readers' request, the evaluation of electronic periodical database has become an urgent problem to be solved in university libraries. In this paper, the fuzzy comprehensive evaluation method is used to evaluate the electronic journal database, and through empirical research, a scientific and reasonable evaluation system of electronic periodical database is explored. This article mainly carries on the research from the following several aspects: 1) the evaluation problem of the complex electronic periodical database is divided into an evaluation system which includes 5 first-grade indexes and 30 second-level indexes. The indicators are both general and comprehensive, and easy to obtain at the same time. In order to simplify the complex problem. In the process of weight analysis, the expert's prior weight is determined by the direct weighting method considering the rational distribution of the expert's weight. The system clustering method is used to determine the posterior weight, the convex combination is used to obtain the objective expert comprehensive weight, and the group decision method is used to integrate the multi-expert judgment according to the weighted synthetic vector ranking method. Finally, the comprehensive sorting vector of each factor is obtained. The fuzzy comprehensive evaluation method is adopted, the qualitative and quantitative indexes of the evaluation system are unified, and the fuzzy boundary and type of the index of the evaluation system of the electronic periodical database are solved. Through the evaluation of the overall level of electronic journal database, and the index level of each criterion layer, the second level index grade of each program level. This paper determines the purchasing decision of electronic periodical database. The weight vector of evaluation factor is the comprehensive sorting vector obtained by the group AHP. At the same time, the method of weighted average is used to analyze the evaluation results. The conclusion of evaluation is more scientific and reasonable. 4) using empirical research to verify the rationality and feasibility of the evaluation system. Finally, the research on the evaluation system of electronic journal database is summarized, and the future work is prospected.
