【摘要】：相關性作為情報學基本問題與信息檢索領域的核心概念這一觀點已經得到國內外學界的普遍認可,其理論成果和實證成果都頗為豐碩。近年來,合作信息查尋與檢索正逐漸成為圖書情報領域的研究熱點,其研究范圍與內容都取得了長足的發(fā)展,但是對相關性這一基本問題的研究卻很少涉及。鑒于此,本研究采取自然主義的方法探究合作信息查尋與檢索中群體用戶合作相關性判斷影響因素,并基于此構建合作信息查尋與檢索的相關性模型。本研究的主要內容和成果如下：(1)識別合作信息查尋與檢索相關性判斷的影響因素集。以4個具有真實信息需求的合作群體用戶為研究對象,利用觀察、出聲思維法、訪談等多種形式收集他們合作信息查尋與檢索的相關性判斷過程數(shù)據,通過扎根理論的三級編碼方式對案例進行分析,最終歸納出5個合作信息查尋與檢索相關性判斷影響因素范疇,分別為語境、主體特質、需求與目標、信息交流、分工與角色。(2)編制合作信息查尋與檢索相關性判斷影響因素量表。根據前述合作相關性判斷影響因素范疇下的具體編碼并結合文獻中的研究成果,編制合作信息查尋與檢索相關性判斷影響因素量表,并通過項目分析、探索性因素分析等方法分析預調研數(shù)據,檢驗篩選量表項目,形成合作信息查尋與檢索相關性判斷影響因素正式量表。(3)構建合作信息查尋與檢索相關性判斷的影響因素模型。根據扎根理論編碼結果和前人研究結果構建合作信息查尋與檢索的相關性判斷影響因素初始模型,利用上述量表收集問卷523份,其中有效問卷501份,利用結構方程模型對初始模型進行分析與驗證。(4)構建合作信息查尋與檢索相關性模型�；贛izarro四維模型和群體決策判斷模型構建合作信息查尋與檢索相關性模型,闡釋了合作相關性就是用戶的群體信息需求集合與信息資源集合在信息交流和用戶心理作用下在個體和群體間達成共識的匹配關系。
[Abstract]:Relevance as the basic problem of information science and the core concept in the field of information retrieval has been widely accepted by scholars both at home and abroad, and its theoretical and empirical results are very rich in recent years. Cooperative information search and retrieval is gradually becoming the research hotspot in the field of library and information. Its research scope and content have made great progress, but the research on the basic issue of correlation is rarely involved. In view of this. This study adopts a naturalistic approach to explore the impact factors of cooperative information search and retrieval in the judgment of cooperative relevance of group users. Based on this model, the correlation model of cooperative information search and retrieval is constructed. The main contents and results of this study are as follows: 1). Identification of cooperative information search and retrieval relevance of the set of influencing factors. Four groups of users with real information needs as the research object. Using observation, voice thinking, interviews and other forms to collect their cooperative information search and retrieval of correlation judgment process data, through rooted theory of three-level coding method to analyze the case. Finally, five categories of cooperative information search and retrieval relevance judgment are concluded, which are context, subject characteristics, needs and objectives, and information exchange. Division of labor and role. 2) compiling the scale of factors influencing the judgment of correlation between search and retrieval of cooperative information. According to the above cooperativeness judgment, the specific codes under the category of influencing factors and the research results in the literature are combined. To compile the cooperative information search and retrieval correlation judgment factors scale, and through item analysis, exploratory factor analysis and other methods to analyze the pre-survey data, test and screen the items of the scale. Formal scale of factors influencing the judgment of correlation between Cooperative Information search and Retrieval. Based on the coding results of rooted theory and previous research results, the initial model of influencing factors of cooperative information search and retrieval is constructed. 523 questionnaires were collected with the scale mentioned above, among which 501 valid questionnaires were collected. Using structural equation model to analyze and verify the initial model. The correlation model of cooperative information search and retrieval is constructed, and the correlation model of cooperative information search and retrieval is constructed based on Mizarro four-dimensional model and group decision judgment model. It is explained that cooperative relevance is the matching relationship between user's group information demand set and information resource set under the action of information exchange and user psychology, which can reach a consensus between individual and group under the influence of information exchange and user psychology.
