1Pang, N. ; Karanasios, S. ; Anwar, M.: Exploring the information worlds of older persons during disasters.
In: Journal of the Association for Information Science and Technology. 71(2020) no.6, S.619-631.
Abstract: While there is a growing body of research on information behavior during nonroutine events such as natural disasters, the research has largely neglected older persons as a specific group despite their identification as a demographic that suffers disproportionately during disasters. To address this gap, this article reports on the study of the information behavior and related activities of older persons during natural disasters. Based on a qualitative study, we draw on the theory of information worlds to study the key activities of preparing, responding, and recovering from disasters. The article contributes to the information behavior literature by developing a more informed understanding of both the interrelationship between the information worlds and activities of older persons, and how older persons seek and share information during disasters.

In: Journal of the Association for Information Science and Technology. 68(2017) no.6, S.1411-1428.
Abstract: The domain of cultural variations in interpersonal communication is becoming increasingly important in various areas, including human-human interaction (e.g., business settings) and human-computer interaction (e.g., during simulations, or with social robots). User-generated content (UGC) in social media can provide an invaluable source of culturally diverse viewpoints for supporting the understanding of cultural variations. However, discovering and organizing UGC is notoriously challenging and laborious for humans, especially in ill-defined domains such as culture. This calls for computational approaches to automate the UGC sensemaking process by using tagging, linking, and exploring. Semantic technologies allow automated structuring and qualitative analysis of UGC, but are dependent on the availability of an ontology representing the main concepts in a specific domain. For the domain of cultural variations in interpersonal communication, no ontological model exists. This paper presents the first such ontological model, called AMOn+, which defines cultural variations and enables tagging culture-related mentions in textual content. AMOn+ is designed based on a novel interdisciplinary approach that combines theoretical models of culture with crowdsourced knowledge (DBpedia). An evaluation of AMOn+ demonstrated its fitness-for-purpose regarding domain coverage for annotating culture-related concepts mentioned in text corpora. This ontology can underpin computational models for making sense of UGC.

In: Journal of the American Society for Information Science and Technology. 64(2013) no.12, S.2452-2467.
Abstract: Social web content such as blogs, videos, and other user-generated content present a vast source of rich "digital-traces" of individuals' experiences. The use of digital traces to provide insight into human behavior remains underdeveloped. Recently, ontological approaches have been exploited for tagging and linking digital traces, with progress made in ontology models for well-defined domains. However, the process of conceptualization for ill-defined domains remains challenging, requiring interdisciplinary efforts to understand the main aspects and capture them in a computer processable form. The primary contribution of this article is a theory-driven approach to ontology development that supports semantic augmentation of digital traces. Specifically, we argue that (a) activity theory can be used to develop more insightful conceptual models of ill-defined activities, which (b) can be used to inform the development of an ontology, and (c) that this ontology can be used to guide the semantic augmentation of digital traces for making sense of phenomena. A case study of interpersonal communication is chosen to illustrate the applicability of the proposed multidisciplinary approach. The benefits of the approach are illustrated through an example application, demonstrating how it may be used to assemble and make sense of digital traces.

Abstract: Over the last 7 years, the AIMTech Research Group in the University of Leeds has used cultural-historical activity theory (CHAT) to inform a range of research activities in the fields of information behavior and information systems. In this article, we identify certain openings and theoretical challenges in the field of information behavior, which sparked our initial interest in CHAT: context, technology, and the link between practice and policy. We demonstrate the relevance of CHAT in studying information behavior and addressing the identified openings and argue that by providing a framework and hierarchy of activity-action-operation and semantic tools, CHAT is able to overcome many of the uncertainties concerning information behavior research. In particular, CHAT provides researchers a theoretical lens to account for context and activity mediation and, by doing so, can increase the significance of information behavior research to practice. In undertaking this endeavour, we have relied on literature from the fields of information science and others where CHAT is employed. We provide a detailed description of how CHAT may be applied to information behavior and account for the concepts we see as relevant to its study.
