These days, every business is trying to achieve its competitive goals. In other words, if one business uses the most modern analytical technologies optimally, it will certainly boost its success level at an exponential rate. The Islamic Republic News Agency (IRNA) is one such mass media industry that, according to its need, uses the benefits information technology (IT) provides it with. News flows, surveys, human resource management, warehouse management, software are key parts of the agency’s news penetration criteria. There is little software that focuses on analytical solutions for running the business optimally. This paper, among available text mining methods, intends to present the most important keywords of news texts based on weighing of words and their correlations, news classification, news sentiments, news trends in order to provide insights and patterns for future scholars and practitioners in the field. This approach will help news agencies maintain their competitive edge as well as predict and react to the market of news search and provision in a timely context-based manner. [ABSTRACT FROM AUTHOR]

Full-text articles are mostly provided in electronic formats, but it still remains a challenge to find deeply related works beyond the keywords and abstract contexts. Identification of related scientific articles based on keywords and abstracts help researchers to find desired and informative content, but it requires the utilization of variety of text analytics (mining) methods to address the need. This study investigates information systems (IS) articles to cluster and evaluate the domain of knowledge of recent Information Systems publications using text clustering methods and then to predict the exact clusters of knowledge of new articles using classification methods. This categorization and predictive learning approach help the scholars and practitioners to find the most relevant articles for their researches and practical endeavors through an automated mechanism. Articles have been collected from the Scopus repository. The dataset has been narrowed to specific areas of recent information systems research. Different text analytics methods such as text normalization, natural language processing (NLP) and clustering algorithms have been applied and the results for each cluster are evaluated by extensive analysis of identified clusters based on their terms frequency and key phrases. Afterwards, different classification algorithms are applied to learn the current clustering and to predict the major subject focus of a newly published article based on the abstract approximation to the previously learned domains of information systems knowledge. The prediction approach helps the scholars identifying the usability of many articles for further research. [ABSTRACT FROM AUTHOR]
