Genres and the Web - is the home page the first digital genre?Dillon, Andrew, Grushowski, Barbara 01 1900 (has links)
Genre conventions emerge across discourse communities over time to support the communication of ideas and information in socially and cognitively compatible forms. Digital genres frequently borrow heavily from the paper world even though the media are very different. This research sought to identify the existence and form of a truly digital genre. Preliminary results from a survey of user perceptions of the form and content of web home pages reveal a significant correlation between commonly found elements on such home pages and user preferences and expectations of type. Results suggest that the personal home page has rapidly evolved into a recognizable form with stable, user-preferred elements and thus can be considered the first truly digital genre.

User-Thesaurus Interaction on a Web-based Database: An Evaluation of Users' term Selection BehaviourShiri, Ali Asghar, Revie, Crawford January 2001 (has links)
A major challenge faced by users during the information search and retrieval process is the selection of search terms for query formulation and expansion. Thesauri are recognised as one source of search terms which can assist users in query construction and expansion. As the number of electronic thesauri attached to information retrieval systems has grown, a range of interface facilities and features have been developed to aid users in formulating their queries. The pilot study reported here aimed to explore and evaluate how a thesaurus-enhanced search interface assisted end-users in selecting search terms. Specifically, it focused on the evaluation of users' attitudes toward both the thesaurus and its interface as tools for facilitating search term selection for query expansion. Thesaurus-based searching and browsing behaviours adopted by users while interacting with a thesaurus-enhanced search interface were also examined

User acceptance of new information technology: theories and modelsDillon, Andrew, Morris, Michael G. January 1996 (has links)
This item is not the definitive copy. Please use the following citation when referencing
this material: Dillon, A. and Morris, M. (1996) User acceptance of new information
technology - theories and models. In: M. Williams (ed.) Annual Review of Information
Science and Technology, Vol. 31, Medford NJ: Information Today, 3-32. ABSTRACT:
Understanding the factors that influence user acceptance of information technology is of
interest both to researchers in a variety of fields as well as procurers of technology for
large organizations. The present chapter reviews literature which demonstrates the nature
of technological acceptance is mediated by distinct factor groups related to the
psychology of the users, the design process of information technology, and the quality of
the technology in user terms. It is concluded that current research offers insights that can
support the derivation of reliable predictions of user acceptance. However, potentially
overlapping theories seem to exist independently of each other and there exists scope for
a unifying framework to extend innovation diffusion concepts and systems design models
(particularly user-centered design) into a formal theory of user acceptance of information
technology.

How collaborative is collaborative writing? An Analysis of the production of two technical reportsDillon, Andrew January 1993 (has links)
Published in: M.Sharples (Ed) Computer Supported Collaborative Writing. (London: Springer-Verlag) 1993. pp 69-86. INTRODUCTION:
Psychologists have been taking an increasing interest in the writing process over the last
decade and models of human cognition and task behaviour during writing are emerging
(see e.g., Hayes and Flower 1980, Sharples et al 1989). Though we are far short of a
complete model of this process several basic components have been identified and most
theorists allude to these at some stage in their description. For example, it is reckoned (as
much from common sense as experimental analysis) that most writing proceeds through a
basic sequence of actions from a rough plan through a draft to a revision stage which may
occur cyclically until the writer believes the document is ready. Plans can be considered
as either detailed or vague, influenced by expectations of the readerâ s knowledge, the
typical form of the document being produced and so forth. The drafts may vary from the
extremely sketchy to the almost complete depending on the writerâ s experience,
knowledge of the subject, preferred writing style etc. and revisions include such acts as
minor spell checking, proofreading or complete re-writes.

Individual Differences in Personal Information ManagementGwizdka, Jacek, Chignell, Mark January 2007 (has links)
In an increasingly complex world where people routinely handle large amounts of information, individuals are constantly challenged to manage and effectively use the information that they are responsible for. While email is the canonical example of an information overloading application, other well known PIM applications and tasks cited in earlier chapters of this book include maintaining addresses and contacts, scheduling, and organizing the various documents and bookmarks that one is interested in. Not surprisingly, there are individual differences (ID) in how, and how well, people cope with the challenge of personal information management. This greatly complicates any scientific analysis of PIM behavior. Thus, in addition to the evaluation methods discussed in the previous chapter, researchers and designers need to consider when and how individual differences should be included within parsimonious interpretations and explanations of PIM behavior. In this chapter we propose an approach where differences between individuals are considered last, after the influences of the environment and the task context have first been considered, and after group difference (e.g., between job classifications) have been investigated. We believe that this is a logical way to proceed, since like observing an ant walking over sand-dunes (cf. Simon, 1996) we should not ascribe complexities to an individual if they can instead be explained as due to properties of the environment.
The goal of this chapter will be to review and synthesize some of the key findings in how PIM behavior differs between individuals. Some of the reasons why these differences occur and what can be done about them will also be discussed.

An exploratory study of human clustering of Web pagesKhoo, Christopher S.G., Ng, Karen, Ou, Shiyan January 2002 (has links)
This study seeks to find out how human beings cluster Web pages naturally. 20 Web pages retrieved by the Northern Light search engine for each of 10 queries were sorted by 3 subjects into categories that were natural or meaningful to them. It was found that different subjects clustered the same set of Web pages quite differently and created different categories. The average inter-subject similarity of the clusters created was a low 0.27. Subjects created an average of 5.4 clusters for each sorting. The categories constructed can be divided into 10 types. About 1/3 of the categories created were topical. Another 20% of the categories relate to the degree of relevance or usefulness. The rest of the categories were subject-independent categories such as format, purpose, authoritativeness and direction to other sources. The authors plan to develop automatic methods for categorizing Web pages using the common categories created by the subjects. It is hoped that the techniques developed can be used by Web search engines to automatically organize Web pages retrieved into categories that are natural to users.

An empirical comparison of the usability for novice and expert searchers of a textual and a graphic interface to an art-resource databaseDillon, Andrew, Song, Min January 1997 (has links)
This item is not the definitive copy. Please use the following
this material: Dillon, A. and Song M. (1997) An empirical
novice and expert searchers of a textual and a graphic
database, Journal of Digital Information, 1(1). Abstract: The present paper reports an experimental test of a prototype graphic and textual search interface for a university database on art-resource works. Novice and expert searchers were tested on both interfaces with performance assessed in terms of search speed and accuracy. Verbal protocols and navigation strategies were also examined. Experts performed significantly faster than novices though both user groups performed slightly (but not significantly) faster with the graphical interface. Furthermore, the graphical interface significantly reduced navigation effort. While there were no significant task accuracy differences, novices failed to complete more searches with the textual interface. Implications of these results for search interfaces to digital resources are briefly discussed.
