【摘要】：相關(guān)性作為情報(bào)學(xué)基本問(wèn)題與信息檢索領(lǐng)域的核心概念這一觀點(diǎn)已經(jīng)得到國(guó)內(nèi)外學(xué)界的普遍認(rèn)可,其理論成果和實(shí)證成果都頗為豐碩。近年來(lái),合作信息查尋與檢索正逐漸成為圖書(shū)情報(bào)領(lǐng)域的研究熱點(diǎn),其研究范圍與內(nèi)容都取得了長(zhǎng)足的發(fā)展,但是對(duì)相關(guān)性這一基本問(wèn)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(hù)合作相關(guān)性判斷影響因素,并基于此構(gòu)建合作信息查尋與檢索的相關(guān)性模型。本研究的主要內(nèi)容和成果如下：(1)識(shí)別合作信息查尋與檢索相關(guān)性判斷的影響因素集。以4個(gè)具有真實(shí)信息需求的合作群體用戶(hù)為研究對(duì)象,利用觀察、出聲思維法、訪(fǎng)談等多種形式收集他們合作信息查尋與檢索的相關(guān)性判斷過(guò)程數(shù)據(jù),通過(guò)扎根理論的三級(jí)編碼方式對(duì)案例進(jìn)行分析,最終歸納出5個(gè)合作信息查尋與檢索相關(guān)性判斷影響因素范疇,分別為語(yǔ)境、主體特質(zhì)、需求與目標(biāo)、信息交流、分工與角色。(2)編制合作信息查尋與檢索相關(guān)性判斷影響因素量表。根據(jù)前述合作相關(guān)性判斷影響因素范疇下的具體編碼并結(jié)合文獻(xiàn)中的研究成果,編制合作信息查尋與檢索相關(guān)性判斷影響因素量表,并通過(guò)項(xiàng)目分析、探索性因素分析等方法分析預(yù)調(diào)研數(shù)據(jù),檢驗(yàn)篩選量表項(xiàng)目,形成合作信息查尋與檢索相關(guān)性判斷影響因素正式量表。(3)構(gòu)建合作信息查尋與檢索相關(guān)性判斷的影響因素模型。根據(jù)扎根理論編碼結(jié)果和前人研究結(jié)果構(gòu)建合作信息查尋與檢索的相關(guān)性判斷影響因素初始模型,利用上述量表收集問(wèn)卷523份,其中有效問(wèn)卷501份,利用結(jié)構(gòu)方程模型對(duì)初始模型進(jìn)行分析與驗(yàn)證。(4)構(gòu)建合作信息查尋與檢索相關(guān)性模型�；贛izarro四維模型和群體決策判斷模型構(gòu)建合作信息查尋與檢索相關(guān)性模型,闡釋了合作相關(guān)性就是用戶(hù)的群體信息需求集合與信息資源集合在信息交流和用戶(hù)心理作用下在個(gè)體和群體間達(dá)成共識(shí)的匹配關(guān)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.
