- Abstract
- General sentiment analysis for the social web has become increasingly useful for shedding light on the role of emotion in online communication and offline events in both academic research and data journalism. Nevertheless, existing general-purpose social web sentiment analysis algorithms may not be optimal for texts focussed around specific topics. This article introduces 2 new methods, mood setting and lexicon extension, to improve the accuracy of topic-specific lexical sentiment strength detection for the social web. Mood setting allows the topic mood to determine the default polarity for ostensibly neutral expressive text. Topic-specific lexicon extension involves adding topic-specific words to the default general sentiment lexicon. Experiments with 8 data sets show that both methods can improve sentiment analysis performance in corpora and are recommended when the topic focus is tightest.

- Abstract
- Purpose - The purpose of this paper is to examine the question of whether modern digital information technologies damage their users' cognitive capacities in some way, and to speculate on how librarians should adapt their services as a consequence of the controversy surrounding this question. Design/methodology/approach - The paper reviews some recent literature on this subject, combined with an examination of the role played by technology, librarians and government in determining the nature of our society's response to problematic aspects of the use of digital, internet-based applications in education. Findings - The paper finds that highly differentiated and highly polemical attitudes to this subject mean that librarians have to acknowledge the existence of important challenges to the apparent consensus about the way information technologies should be used in education in Western societies. This has important consequences for the approach to collection building (the balance between digital versus print provision), for library building design, and for the value which should be placed on systematic information literacy teaching. The existence of such an important debate should also embolden information professionals to make their own insights into these issues more widely known. Research limitations/implications - Some of the findings in this paper are amenable to further development through practitioner-oriented research; however, the bulk of the content used for this paper is derived from the literature on this topic, so there is no original research data presented to back up the assertions made by the author. It is simply an account of a debate which has to be acknowledged by librarians. Practical implications - The implications of the issues under discussion in the paper are presented in clear practical terms, and the consequences for library management made explicit. Social implications - The clash between two different theories of learning and information provision is debated and the links with issues of government policy are explored. The social connections between education and wealth generation are brought into this debate. Originality/value - The paper provides a useful, up-to-date briefing on recent controversial issues in education, information management and socio-economic policy making.

- Abstract
- Online social networks (OSNs) have been built as platforms for information sharing, with their concomitant potential for misuse of information and unsafe sharing practices. The frontline of defense against such threats is the "privacy settings" controls provided by OSNs such as Facebook. However, the efficacy of these settings is often undermined by their poor design. The current design fatigues users with information overload and fails to provide them with a more integrative and global understanding of their information-sharing practices. In this article, we develop a more efficacious design for the display of OSNs' privacy settings by following recommendations for appropriate use of visualization techniques. The new "wheel" interface simplifies the presentation of privacy settings to reduce information overload. It also incorporates an additional layer of information, indicating the safety of users' settings. A within-subject experiment with 67 students suggests that this interface is more versatile than the current tabular interfaces typically used on OSNs. More important, it allows users to easily comprehend complex information and provides them with a more integrative, higher level understanding of their privacy settings. This research focuses on an important niche at the intersection of information representation, interface design, and OSN privacy.
