Implicit Measures of Lostness and Success in Web Navigation

In two studies, we investigated the ability of a variety of structural and temporal measures computed from a web navigation path to predict lostness and task success. The user’s task was to find requested target information on specified websites. The web navigation measures were based on counts of visits to web pages and other statistical properties of the web usage graph (such as compactness, stratum, and similarity to the optimal path). Subjective lostness was best predicted by similarity to the optimal path and time on task. The best overall predictor of success on individual tasks was similarity to the optimal path, but other predictors were sometimes superior depending on the particular web navigation task. These measures can be used to diagnose user navigational problems and to help identify problems in website design

To Archive or Not to Archive: The Resistant Potential of Digital Poetry

This essay addresses the much discussed problem of archiving digital poetry. Digital media are labile, and several writers of digital poetry are incorporating the media’s ephemerality into their poetics. Rather than rehash arguments that have been taking place within the field of digital media and digital poetics for years, I turn to the field of contemporary art curation and preservation, a field in which curators and archivists are struggling with the very immediate concerns, ethical and otherwise, related to archiving works that are made from ephemeral media. One particular digital poem that has recently broken, has recently become unreadable, is Talan Memmott’s Lexia to Perplexia. Memmott composed the poem in 2000, and he incorporated the poem’s inevitable obsolescence into the text of the poem itself. He has since refused to “fix” or “update” the poem, because he contends that that would make it something other than what it was intended to be. Rather, he is choosing to let the poem die because that is what the poem is supposed to do. This essay concludes with a discussion of the political implications of acknowledging the ephemerality of digital media, the resistant potential of the poem when its ephemerality is embraced, and some ways in which archivists can preserve the memory of the poem without necessarily preserving the poem itself

Hunter gatherer: within-web-page collection making

Hunter Gatherer is a tool that lets Web users carry out three main tasks: (1) collect components from within Web pages; (2) represent those components in a collection; and (3) edit those collections. We report on the design and evaluation of the tool and contextualize tool use in terms of our research goals to investigate possible shifts in information interaction practices resulting from tool use

Textual Space and Metafiction in Mark Z Danielewski's House of Leaves

The thesis presents an argument that through employing metafictional techniques, experimentation with textual and graphic space and allusions to hypertextual devices, Mark Z. Danielewski's House of Leaves seeks to remind the reader of the presence of the book in print fiction. Danielewski dispenses with traditional textual formats in order to provoke the reader to realise the presence of the physical book in their hands. This is mirrored in the narrative as two of the main characters both obtain a copy of the very same book that the reader is holding. The author employs metafictional characteristics such as characters that acknowledge their fictional status whilst writing a book within a book. The first chapter of the thesis examines the potential of metatexts and criticism in the twenty-first century and a questioning of its continued relevance. Danielewski challenges textual space that potentially distances the reader from the narrative. There is an overwhelming amount of blank space in the text where there could have been narrative. The reader is told on several occasions that parts of the narrative are missing. Chapter Two is concerned with references to the book and the unconventional page aesthetics that encourage the reader to initially look at the page before actually 'looking through the page'. The final chapter compares House of Leaves with the hypertext fictions that it so often mirrors. The two forms of literature, whilst initially seeming quite different are actually very similar in narrative and form. House of Leaves appears to draw on some of the conventions associated with hypertext fiction in order to provide the reader a more active role in the reading of the text, whilst allowing them to understand the conventions of the writing. The experimentation with conventional textual space, metatextual techniques and references to electronic literature in House of Leaves challenge the nature of the physical book and its presence in contemporary prose fiction

After the education disciplines: teaching theory on-line.

Like all social theorising, the academic study of education is 'reflexive'- complicated by the fact of our immersion in it. This paper discusses an on-line version of an undergraduate teacher-education course, 'Social Issues in New Zealand Education,' that is designed to teach its students how to do such 'situated' educational theorising. Consistent with this theme, the paper is written as a stream-of-consciousness narrative. In an attempt to fix in print the 'counterpoint' of pedagicical theorising in general, as well as more specifically in an on-line setting, it is episodic in structure - more like the lateral leaps of hypertext than the disciplined hierarchies of headings characteristic of the linearity of conventional academic argument. It falls into three parts. The first introduces the online virtual classroom environment in which the teaching takes place. Part two locates the course within more general epistemological issues confronting designers of education (foundations) courses in pre-service teaching degrees in the twenty-first century. In Part three, the syllabus of the course is outlined. The paper concludes with examples of students doing 'situated' educational theorising as they engage with course readings and assignments. Through this multi-layered account, I raise for discussion some broad questions about pedagogy in educational foundations courses in today's environment

The live social semantics application: A platform for integrating face-to-face presence with on-line social networking

We describe a novel application that integrates real-world data on the face-to-face proximity of individuals with their identities and contacts in on-line social networks. This application was successfully deployed at two conference gatherings, ESWC09 and HT2009, and actively used by hundreds of people. Personal profiles of the participants were automatically generated using several Web 2.0 systems and semantic data sources, and integrated in real-time with face-to-face proximity relations detected using RFID-enabled badges. The integration of these heterogeneous data sources enables various services that enhance the experience of conference attendees, allowing them to explore their social neighbourhood and to connect with other participants. This paper describes the architecture of the application, the services we provided, and the results we achieved in these deployments
