1 Fifty years of information management research: A conceptual structure analysis using structural topic modeling
پنجاه سال تحقیقات مدیریت اطلاعات: تجزیه و تحلیل ساختار مفهومی با استفاده از مدل سازی موضوع ساختاری-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 infor- mation. 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 infor- mation 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 in- formation 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.

2 Capturing distinctions while mining text data: Toward low-tech formalization for text analysis
گرفتن تمایزات در حین استخراج داده های متنی: به سوی رسمی سازی تکنولوژی کم برای تجزیه و تحلیل متن-2018
In this article we consider some low-tech approaches to text mining. Our goal is to articulate a RiCH (Reader in Control of Hermeneutics) style of text analysis that takes advantage of the digital affordances of modern reading practices and easily deployable computational tools while also preserving the primacy of the interpretive lens of the human reader. In the article we offer three analytical interventions that are suitable to the low-tech formalizations we propose: the first and most developed intervention tracks the (normally computationally ignored) “stop” words; the second identifies the use of strategic anxiety terms in the texts; and the third (less developed in this article) introduces the grammatical features of modality (including modalization statements of probability and usuality, and modulation statements regarding degrees of obligation and in clination). All three analytical interventions provide a productive tracking of various modes and degrees of strategic decisiveness, contradiction, uncertainty and indeterminacy in a corpus of recent U.S. National Security Strategy reports.

Turning user generated health-related content into actionable knowledge through text analytics services-2016
In the last years, the habit of discussing healthcare issues with family and friends, even with unknown people, in the context of social networks has increased and processing user generated content has become a new challenge. This can help in on-line crowd surveillance for different applications (pharmacovigilance and filtering health contents in blogs among others) as well as extracting knowledge from unstructured text sources. In this article, a system that monitors health social media streams is described. It is based on several text analytics processes supported, among others, by MeaningCloud, a commercial platform which provides meaning extraction from texts in a Software as a Service mode. In this architecture, several domain resources are integrated to detect drugs and drug effects such as CIMA (official information about authorized drugs in Spain maintained by the Spanish Agency of Medicines and Health Products), MedDRA (Medical Dictionary for Regulatory Activities) and the SpanishDrugEffectDB database that contains relations between drugs and effects. Different ways of visualizing data considering time lines and aggregated data have been implemented. In order to show performance, an evaluation has been carried out over Named Entities Recognition (NER) and Relation Extraction (RE) tasks.© 2015 Elsevier B.V. All rights reserved.
