Text mining is an instrumental technology that today’s organizations can employ to extract information and further evolve and create valuable knowledge for more effective knowledge management. It is also an important tool in the arena of information systems security (ISS). While a plethora of text mining research has been conducted in search of revamped technological developments, relatively limited attention has been paid to the applicable insights of text mining in ISS. In this chapter, we address a variety of technological applications of text mining in security issues. The techniques are categorized according to the types of knowledge to be discovered and the text formats to be analyzed. Privacy issues of text mining as well as future trends are also discussed.

Social media and the interactive Web have enabled human traffickers to lure victims and then sell them faster and in greater safety than ever before. However, these same tools have also enabled investigators in their search for victims and criminals. Authors used system development action research methodology to create and apply a prototype designed to identify victims of human sex trafficking by analyzing online ads. The prototype used a knowledge management approach of generating actionable intelligence by applying a set of strong filters based on an ontology to identify potential victims. Authors used the prototype to analyze a dataset generated from online ads from southern California and used the results of this process to generate a revised prototype that included the use of machine learning and text mining enhancements. An unexpected outcome of the second dataset was the discovery of the use of emojis in an expanded ontology.

This article reports on the development of a knowledge management (KM) dictionary and its application to automated content analysis to investigate topical foci of KM publications and provide an overview of the current research landscape. While automated content analysis gains importance, a problem prevails concerning the use and analysis of compound concepts (e.g., organizational learning). Using a self-developed dictionary of KM-related compound concepts, a sample of 4,290 publications from ten top-ranked KM journals and one KM conference was analyzed using text-mining software. Based on the dictionary approach, this study investigates core research themes of the KM discipline and compares key research interests throughout the IJKM community and those of other outlets. The investigation provides guidance to identify research opportunities in KM and provides useful implications concerning the application of dictionaries. Practitioners might adapt their organizations' approaches to KM accordingly, with regard to prevailing themes and trends in KM research.

Background and Objectives: Nowadays, due to the increasing publication of articles in various scientific fields, analysis of the topics published in specialized journals is interesting for researchers and practioners. For this purpose, this study has identified and analyzed the issues published in the Iranian library and medical librarianship articles. Material and Method: This study uses an exploratory and descriptive approach to analyze the library and information articles published in specialized journals in this field in Iran from 1997 to 2017 using text mining techniques. For this purpose, 982 articles on the library and medical librarianship have been selected from 16 journals. The TF-IDF weighting algorithm was used to identify the most important terms used in the articles and the LDA thematic modeling algorithm was used to determine the published topics. Python programming language has also been used to run text mining algorithms. Results: Results showed that the words of library (12.67), journal (12.47), information (12.23), hospital (9.90) and scientific (9.74) are the most important words based on their TF-IDF weight. The results of thematic modeling of these articles were based on the highest publication rates of scientometrics, information literacy, health information, knowledge management, webometrics, and the quality of the website and hospital information systems, respectively. Conclusion: The results of this study showed that the topics of scientometrics, information literacy and health information have had the highest publication in the last 5 years. Also, the publication of knowledge management, webometrics and quality of the website and hospital information system has been less published in the last 5 years than in the past.
