Abstract: Multitasking information behaviour is the human ability to handle the demands of multiple information tasks concurrently. When we multitask, we work on two or more tasks and switch between those tasks. Multitasking is the way most of us deal with the complex environment we all live in, and recent studies show that people often engage in multitasking information behaviours. Multitasking information behaviours are little understood, however, and an important area of research for information behaviour research. Our study investigated the multitasking information behaviours of public library users at the Brentwood and Wilkinsburg Public Libraries in Pittsburgh through diary questionnaires. Findings include that some 63.5 percent of library users engaged in multitasking information behaviours, with a mean of 2.5 topic changes and 2.8 topics per library visit. A major finding of our study is that many people in libraries are seeking information on multiple topics and are engaged in multitasking behaviours. The implications of our findings and further research are also discussed.

Abstract: Digital social media has, in many ways, transformed the way people create, maintain, and sustain their social information networks, and has also influenced their information-related behaviours such as searching, seeking, finding and use of information. This is especially true in technologically-mediated environments. In many ways, social media is the contemporary incarnation of the Internet itself. It is a complex information-and-communication environment, very much analogous to physical environments, but consisting of symbolic matter rather than physical matter. All social situations are information environments and social media is no different. This paper is an inter-disciplinary literature-review essay that examines the social media phenomenon using the lens of selected theories in information science and allied disciplines such as communication and media ecology with a specific focus toward its possible role in civil society using the conceptual framework of spatial metaphors drawn from the study of traditional physical environments.

Abstract: This paper reviews different types of conversational agents used in health care for chronic conditions, examining their underlying communication technology, evaluation measures, and AI methods. A systematic search was performed in February 2021 on PubMed Medline, EMBASE, PsycINFO, CINAHL, Web of Science, and ACM Digital Library. Studies were included if they focused on consumers, caregivers, or healthcare professionals in the prevention, treatment, or rehabilitation of chronic diseases, involved conversational agents, and tested the system with human users. The search retrieved 1087 articles. Twenty-six studies met the inclusion criteria. Out of 26 conversational agents (CAs), 16 were chatbots, seven were embodied conversational agents (ECA), one was a conversational agent in a robot, and another was a relational agent. One agent was not specified. Based on this review, the overall acceptance of CAs by users for the self-management of their chronic conditions is promising. Users’ feedback shows helpfulness, satisfaction, and ease of use in more than half of included studies. Although many users in the studies appear to feel more comfortable with CAs, there is still a lack of reliable and comparable evidence to determine the efficacy of AI-enabled CAs for chronic health conditions due to the insufficient reporting of technical implementation details.

Abstract: The rise in web and social media interactions has resulted in the efortless proliferation of offensive language and hate speech. Such online harassment, insults, and attacks are commonly termed cyberbullying. The sheer volume of user-generated content has made it challenging to identify such illicit content. Machine learning has wide applications in text classification, and researchers are shifting towards using deep neural networks in detecting cyberbullying due to the several advantages they have over traditional machine learning algorithms. This paper proposes a novel neural network framework with parameter optimization and an algorithmic comparative study of eleven classification methods: four traditional machine learning and seven shallow neural networks on two real world cyberbullying datasets. In addition, this paper also examines the effect of feature extraction and word-embedding-techniques-based natural language processing on algorithmic performance. Key observations from this study show that bidirectional neural networks and attention models provide high classification results. Logistic Regression was observed to be the best among the traditional machine learning classifiers used. Term Frequency-Inverse Document Frequency (TF-IDF) demonstrates consistently high accuracies with traditional machine learning techniques. Global Vectors (GloVe) perform better with neural network models. Bi-GRU and Bi-LSTM worked best amongst the neural networks used. The extensive experiments performed on the two datasets establish the importance of this work by comparing eleven classification methods and seven feature extraction techniques. Our proposed shallow neural networks outperform existing state-of-the-art approaches for cyberbullying detection, with accuracy and F1-scores as high as ~95% and ~98%, respectively.

Abstract: Conversational bots, otherwise known as chatbots, operate within the fourth industrial revolution as a client facing form of AI. They are communicative interfaces that mimic human conversation to deliver information in a highly personalised way. The user experience of chatbots can change the way in iduals, groups and organisations define themselves online (Whitley, Gal & Kjaergaard, 2014). This paper discusses the opportunities in building an online identity via chatbots, with emphasis on harnessing the properties of chatbots to develop trust with users. Currently, organisations are limited to the properties and affordances of web browsers, search engines and social media to communicate a “shared symbolic representation” (Gioia, 1998). This paper focuses on organisational identities on the Internet, and details both opportunities and vulnerabilities in establishing trust with users through chatbots.

Abstract: How are information and inspiration connected? Answering this question can help information professionals facilitate the pathways to inspiration. Inspiration has previously been conceptualized as a goal or mode of information seeking, but this says little about the nature of inspiration or how it is experienced. In this study, we explore the connection between information and inspiration through a qualitative approach, using the museum as our setting specifically, the researchers’ own visits to three separate museums. We use collaborative auto-hermeneutics, a methodology specifically suited to such a reflexive exploration, to document and analyze three in idual museum visits. The following research questions were the main driver for this exploratory study: What is inspiration, and How are inspiration and information related? In answer, we present an inductive definition of inspiration as a kind of information, and we discuss how this definition fits in with the information science literature as well as offer some practical applications.

Abstract: The purpose of this paper is to investigate the use of wearable health and fitness trackers in everyday life, and users’ motivations and their understanding and use of the data derived from devices, and understand the results using the lens of information behaviours. The study used a qualitative, constructionist approach, based on 21 interviews with users of a range of wearable activity trackers used for health and fitness. Findings show that the lifelogging devices have become companion tools that enable users to take information from their bodily indicators and make some decisions about their health and fitness, and also track the results when they act on it, thus giving them a sense of gratification and a sense of control over their own health. The findings have implications on how health professionals can talk to their lifelogging patients about how to deal with and understand the information provided by their activity-tracking devices. Some participants in the study already discuss these data regularly with their health professionals. As the self-tracking practices attract wide range research interests from human–computer interaction, information systems, digital sociology, health informatics and marketing among others. This study provides important everyday information-seeking perspective that contributes to the understanding of the practices of how people make sense of the data, how the data improves their wellbeing, i.e. physical health improvement or fitness, and implications to users health behaviour. Additionally the study adds to the lifelogging literature through a constructionist, qualitative approach rather than a technological deterministic approach.

Abstract: This article based on an empirical study of Australian authors argues that, despite the OwnVoices movement gathering momentum in Australia, there are still barriers and limitations for authors from marginalised communities within the Australian publishing industry. This is due to power imbalances in publishing spaces which silence marginalised writers, limiting the availability of their books to teenage readers.

Abstract: The privacy construct is an important aspect of internet of things (IoT) technologies as it is projected that over 20 billion IoT devices will be in use by 2022. Among other things, IoT produces big data and many industries are leveraging this data for predictive analytics to aid decision making in health, education, business, and other areas. Despite benefits in some areas, privacy issues have persisted in relation to the use of the data produced by many consumer products. The practices surrounding IoT and Big Data by service providers and third parties are associated with a negative impact to in iduals. To protect consumers' privacy, a wide range of approaches to informational privacy protections exist. However, in iduals are increasingly required to actively respond to control and manage their informational privacy rather than rely on any protection mechanisms. This chapter highlights privacy issues across consumers' use of IoT and identifies existing responses to enhance privacy awareness as a way of enabling IoT users to protect their privacy.

Abstract: Social media, specifically a microblogging service such as Twitter, constitute a public space that has changed how we interact with, exchange, and respond to information in a civil society. They also have the potential to give public voice to minority narratives that are under-represented in the mainstream media, just as grassroots graffiti in public spaces have done over human history. Using a specific case study around an issue in the Australian national discourse around Australia Day, this study contributes new insights towards an understanding of how alternate narratives are expressed and erased in cyberspace, just as graffiti are erased from public view by the authorities. Widely promoted by official sources as a day of festivity and celebration, the Australia Day Your Way initiative actively promotes the use of the hashtag #AustraliaDay to metatag tweets for capture to an annual time capsule stored by the National Museum of Australia. For Australia’s indigenous minority though, Australia Day is symbolic of an entirely different narrative, expressed online through the hashtags #InvasionDay and #SurvivalDay. We studied all three hashtags and their intersections on Twitter and also compared this data to what was showcased in the official time capsule. We found that although the alternative voices existed on Twitter, they were excluded from the official time capsule. This has implications both for archives and for future historians studying contemporary events.

Abstract: Twitter acts as an information gateway as it provides a place where professionals network and share their knowledge. Twitter has increasingly influenced the way people use and share information. However, limited research demonstrates IT professionals’ information experience on Twitter impacts the way they use it for professional purposes. The study aimed to understand how such information experiences impact on the way IT professionals use Twitter for professional purposes. Eleven IT professionals were recruited for this study to understand the participants’ information experience through their own in idual perspective, with the data analysed using constructive grounded theory. This study revealed that IT professionals’ information experience plays a vital role in creating professional networking and knowledge sharing in online spaces. These lived experiences influence the way IT professionals use Twitter for professional purposes. Thus, the findings of this study contribute to theoretical perspectives in the understanding of information experience perspectives within Twitter, along with a foundational understanding of the ways in which microblogging is used for professional purposes. The findings can help organisations understand and provide for this emerging channel of professional information sharing for its staff and stakeholders.

Abstract: Cultural Heritage Properties (CHPs) around the world have been altered or destroyed due to various unforeseen factors, both natural and human-made. Consequently, as a preparedness approach around such disasters, documenting the CHPs are crucial to any efforts to repair, rebuild or relocate them. With advancements in digital technologies, integrating them into our documentation to improve heritage preservation has become a common approach. Here the main concern is on Spatial and Temporal (ST) information and the paper proposes that with recent developments in the field of Geospatial technologies, heritage preservation can be enhanced and improved by documenting ST information parallel to the other information resources. The study area of this research is the CHPs in Sri Lanka. The paper investigates the present condition of the ST information in the heritage arena and the challenges associated with the same. Finally, the paper suggests a metadata standard to acquire primary level ST information as the initial ST documentation strategy. This can be extended further as a complete standard of good practice for CHP documentation in Sri Lanka.

Abstract: This chapter discusses people’s everyday encounters with information and the difficulties they face in finding information within both personal and professional contexts, with a specific focus on information-organisation-related behaviours in everyday-life, and based on a diary study where participants maintained an information journal. The discussion is based on the literature along with selected findings from a larger empirical study of human information behaviours, which found that information-organisation-related behaviours (including the lack of it) in everyday life is a problematic area due to various factors. The factors include problems with knowledge representation and inter-subjectivity, along with spatiotemporal dimensions that give rise to intra-subjectivity in our minds. These factors have implications on the findability of information and also on personal information management.

Abstract: This paper examines issues relating to the perceptions and adoption of open access (OA) and institutional repositories. Using a survey research design, we collected data from academics and other researchers in the humanities, arts and social sciences (HASS) at a university in Australia. We looked at factors influencing choice of publishers and journal outlets, as well as the use of social media and nontraditional channels for scholarly communication. We used an online questionnaire to collect data and used descriptive statistics to analyse the data. Our findings suggest that researchers are highly influenced by traditional measures of quality, such as journal impact factor, and are less concerned with making their work more findable and promoting it through social media. This highlights a disconnect between researchers’ desired outcomes and the efforts that they put in toward the same. Our findings also suggest that institutional policies have the potential to increase OA awareness and adoption. This study contributes to the growing literature on scholarly communication by offering evidence from the HASS field, where limited studies have been conducted. Based on the findings, we recommend that academic librarians engage with faculty through outreach and workshops to change perceptions of OA and the institutional repository.
