中文数据库(CNKI、维普等)中,尚未出现以"学科知识集成"为关键词的文献。因此,尝试类比企业知识集成的名称、定义对学科知识集成进行定性研究,并归纳出学科知识集成的三大特性:宏观性、动态性、累积性。对比分析知识管理、文献计量学、社会网络分析、科学知识图谱四者与学科知识集成间的关系,进而对学科知识集成定义、性质进行补充。  相似文献

[目的/意义]鉴于全信息是通过自然语言来对事物的形式、内容和价值进行"三位一体"的描述,为了在知识构建(KA)中基于自然语言理解实现对全信息的有效获取和综合利用,使之为用户的知行能力的提升提供显隐智能生成的保障和生长的动力,为KA能力形成建立和谐的知识生态系统结构。[方法/过程]在KA的全信息获取和利用时,应该根据其生成机制及在用户智能活动中的综合作用,采取基于Web 2.0的"人主机辅"和"知行交互"的策略来综合集成规则方法与统计方法,以实现对自然语言的深度理解;并具体采用基于物联网综合集成智能系统的方法来对自然语言结构进行词类识别和关联挖掘。[结果/结论]针对语义Web在全信息表示、知识提炼和智能激活中的先天不足,KA的全信息获取可通过自然语言处理来对其进行分析、提取、表示;KA的全信息利用应采取基于Web 2.0群体智能与物联网综合集成相融合的方式来构建全信息Web(CI-Web)并加以综合利用。  相似文献

College students are at great risk of obesity and overweight, and campaigns encouraging exercise may mitigate associated health risks. Although some factors influential in college student exercise behavior have been reported, important in communication targeting, few have studied differences between overweight and normal weight students. Body mass index influences exercise behavior; thus, cognitive factors may be different in these subpopulations, necessitating different messaging approaches. This study aims to address this gap through theory-based qualitative elicitation work. Results indicate that overweight and normal weight college students differ in their perceived facilitators to regular exercise. Implications for exercise messages are discussed.  相似文献

Research in the social sciences has shown that there are gender differences in the selection of research methods, with women often opting for qualitative methods while men prefer quantitative methods. However, it is important to consider that research methods are generally chosen based on the research topic. To figure out the influence of gender on research method selection, a study was conducted in the field of library and information science, using a more fine-grained method classification system and an automatic classification model called CogFT, which is based on full-text cognition. The findings showed that women tend to use interviews while men prefer theoretical approaches, across a range of topics. Insights into the specific research design processes that contribute to gender differences in method selection are offered and ways to promote gender inclusivity and equality in academia by considering research method use and guidance are suggested.  相似文献

The discipline of communication is marked by an increasing number of means of understanding. Given the recent research explosion, specialization has accordingly become a major way of dealing with research and methodological diversity. Within this context, this analysis is predominantly definitional, seeking to isolate the unique features of qualitative research. This analysis first provides a survey of six major definitions of and approaches to qualitative research. Second, commonly shared characteristics of qualitative research are outlined, including the role that natural setting plays in the research design, the role of the researcher as both observer and participant, how subjects influence the content of a communication study, the influence of subject intentionality on the research report, and the pragmatic uses of qualitative research. Third, it is suggested that qualitative research is theoretically unique, satisfying the requirements for grounded theory. Finally, it is concluded that qualitative research is increasingly finding its own identity when viewed in terms of the goals and procedures of quantitative and critical approaches to communication.  相似文献

模糊综合评判法在图书评标中的应用研究   总被引:4,自引:1,他引:3  
相对于综合评分法而言,模糊综合评判法更适用于评价定性指标,可以将招标中用模糊语言描述的定性属性或信息定量化,较好地克服信息的模糊性,减少招标中的不确定性问题。其模型更为科学严谨,并在一定程度上限制了主观因素对评标的影响,在图书评标中运用模糊综合评判法则更能使评标结果趋于客观、准确、合理。本文结合案例详细介绍了在图书评标中应用模糊综合评判法进行系统评价的建模方法和步骤。  相似文献

Abstract

Newspaper readership is usually measured by a single variable such as frequency of use, amount of use, etc. This article argues that readership cannot be fully described by a single measure and suggests treating it as a latent variable reflecting the time, frequency, and completeness of readership on both Sundays and weekdays. This study uses data from 101 newspaper markets in the US. The latent variable can be either quantitative or qualitative. Factor analysis is used to define the quantitative variable and latent class analysis, the qualitative variable. The relationship between the approaches is studied with principal components analysis, profiling, and hierarchical linear models. The two approaches are shown to produce complementary conclusions when relating readership to demographics and content interests. Media consumption studies can examine both qualitative and quantitative latent variables and thereby enhance the interpretability and the scope of the results.  相似文献

The defining nature and characteristics of qualitative research are surveyed in this article, which identifies key distinctions between method and methodology. The authors note that qualitative research is primarily concerned understanding human beings' experiences in a humanistic, interpretive approach. Issues of research design differences between quantitative and qualitative research are traced with an emphasis on identifying diverse methodologies, including those focusing on analysis of text, and diverse forms of data collection along with criteria for evaluating qualitative research.  相似文献

Preparing library and information science (LIS) professionals for the changing contexts in which they work requires them to understand qualitative research methods. Finding appropriate theories and approaches to teaching qualitative research methods is essential to develop librarians and other graduate students as qualitative researchers. The purpose of this article is to examine and discuss these and other learning theories as well as additional strategies and methods for teaching qualitative research methodology to librarians and novice researchers.  相似文献

Qualitative communication research approaches vary from grounded theory and participant-observation to Q-sort, content analysis, and ethnographic inquiry—to name but a few. What often rests outside the qualitative rubric is the hermeneutic tradition of interpretive scholarship. This essay unites interpretive inquiry and qualitative research in summary fashion by outlining a macro understanding of qualitative communication inquiry, an interpretive approach to communication scholarship within a philosophical tradition entitled philosophical hermeneutics, and finally a public roadmap of how to understand and engage interpretive inquiry as a form of qualitative research in communication. This essay advocates interpretive inquiry as an additional contributor to the ongoing tradition of qualitative research in communication.  相似文献
