The semantic mapping of words and co-words in contexts     

Loet Leydesdorff  Kasper Welbers 《Journal of Informetrics》2011,5(3):469-475

Meaning can be generated when information is related at a systemic level. Such a system can be an observer, but also a discourse, for example, operationalized as a set of documents. The measurement of semantics as similarity in patterns (correlations) and latent variables (factor analysis) has been enhanced by computer techniques and the use of statistics; for example, in “latent semantic analysis”. This communication provides an introduction, an example, pointers to relevant software, and summarizes the choices that can be made by the analyst. Visualization (“semantic mapping”) is thus made more accessible.  相似文献   

The dynamic effect of interactivity on customer engagement behavior through tie strength: Evidence from live streaming commerce platforms     

《International Journal of Information Management》2021

Interactivity, which is a key characteristic of the live streaming commerce environment, fosters users’ active attitudes and behaviors in communications and transactions. However, the literature on live streaming commerce, is scarce, and few studies examine how interactivity influences customers’ non-transactional behaviors from a dynamic perspective. In this setting, based on the stimulus-organism-response (S-O-R) framework, we developed a research model using real-time data to investigate the dynamic effect of interactivity on customer engagement behavior through tie strength in live streaming commerce, which is a relatively new derivative of social commerce. This study developed a text mining method to quantify constructs using a large-scale sample of 3,500,445 online review texts. Our empirical study found that interactivity has a curvilinear relationship with customer engagement behavior. Besides, tie strength plays an intermediary role between interactivity and customer engagement behavior. It was further observed that both tenure of membership and popularity have an important moderating relationship between interactivity and tie strength. The study enriches the relationship marketing theory and live streaming commerce literature. Moreover, this study is one of the first studies to use real-time online data for live streaming commerce research.  相似文献   

Fifty years of information management research: A conceptual structure analysis using structural topic modeling     

《International Journal of Information Management》2021

Information management is the management of organizational processes, technologies, and people which collectively create, acquire, integrate, organize, process, store, disseminate, access, and dispose of the information. Information management is a vast, multi-disciplinary domain that syndicates various subdomains and perfectly intermingles with other domains. This study aims to provide a comprehensive overview of the information management domain from 1970 to 2019. Drawing upon the methodology from statistical text analysis research, this study summarizes the evolution of knowledge in this domain by examining the publication trends as per authors, institutions, countries, etc. Further, this study proposes a probabilistic generative model based on structural topic modeling to understand and extract the latent themes from the research articles related to information management. Furthermore, this study graphically visualizes the variations in the topic prevalences over the period of 1970 to 2019. The results highlight that the most common themes are data management, knowledge management, environmental management, project management, service management, and mobile and web management. The findings also identify themes such as knowledge management, environmental management, project management, and social communication as academic hotspots for future research.  相似文献

A Bayesian feature selection paradigm for text classification     

Guozhong Feng  Jianhua Guo  Bing-Yi Jing  Lizhu Hao 《Information processing & management》2012

The automated classification of texts into predefined categories has witnessed a booming interest, due to the increased availability of documents in digital form and the ensuing need to organize them. An important problem for text classification is feature selection, whose goals are to improve classification effectiveness, computational efficiency, or both. Due to categorization unbalancedness and feature sparsity in social text collection, filter methods may work poorly. In this paper, we perform feature selection in the training process, automatically selecting the best feature subset by learning, from a set of preclassified documents, the characteristics of the categories. We propose a generative probabilistic model, describing categories by distributions, handling the feature selection problem by introducing a binary exclusion/inclusion latent vector, which is updated via an efficient Metropolis search. Real-life examples illustrate the effectiveness of the approach.  相似文献

播客的社会文本意义解读   总被引：4，自引：0，他引：4  

黄桂萍  吴文虎 《国际新闻界》2006,(8)

本文从符号学和传播学的视角,对国内外迅速兴起的“播客”现象进行较为深入的文本意义解读。笔者认为,作为社会文本的播客,其意义是:在播客特定的语境下,人们借助不同的符号系统,使“自我实现”得到最大的满足并正逐步融入社会。从编码者的角度看,这种“自我的实现”的特点是,话语权力的获得和“超符号”的自由交流。而译码者的“自我实现”的特点,则是通过解释权的回归,使可读的文本和可写的文本得以沟通。  相似文献   

浅论苏轼“以才学为诗”     

张国荣 《乐山师范学院学报》2013,28(3):10-16

宋代诗人喜欢"以才学为诗"。苏轼尤甚。苏轼之所以喜好"以才学为诗",自有其不便言说的独特的创伤初衷,这就是:(1)要抒胸中"忧愁不平气",(2)作家(诗人)与学者兼于一身特殊身份所使然,(3)强烈开宗立派意识所驱使。由此形成了苏轼独特的文本类型,即:(1)用典使事型,(2)多次韵型,(3)艺术鉴赏型,(4)因物寓理型。同时,苏轼在"以才学为诗"的实际操作中,自有其一套与之相适应的审美特征:一是经史百家学问穿插互用;二是以才学寓托诗人心志和寻求精神之"适";三是凭才学拓展诗歌题材。此外,苏轼"以才学为诗"具有极其重要的创作意义。  相似文献
