Gwizdka, Jacek and Bakelaar, Philip (2009): Tag trails: navigation with context and history. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 4579-4584. Available online

We describe a technique for preserving and presenting context and history while navigating web resources described by keywords. We use tagging and tag clouds as an application area for our technique. The technique is illustrated by employing it in a prototype that interfaces data from a social tagging website used to bookmark academic articles. The prototype displays a "tag trail" which can reveal contextual connections between web resources and the associated tags. We argue that the user's understanding of web resources is aided by making such connections explicit.

Cole, Michael J. and Gwizdka, Jacek (2008): Tagging semantics: investigations with WordNet. In: JCDL08 Proceedings of the 8th ACM/IEEE-CS Joint Conference on Digital Libraries 2008. p. 446. Available online

The content of a tag sequence references both a user's concepts and the user's conceptualization of an information object. The tagging history of 823 users of the Delicious social tagging service is analyzed using WordNet. Three semantic measures of the tagging content are developed: the level of category references, the changes in category level for each noun as the tagging sequence unfolds, and the scope of concept coverage as the compactness of the WordNet subgraph for the noun senses. Observed patterns of concept reference as a function of sequence position hint at dynamic properties of the tag production process by marking a trace of cognitive activity. If tagging is object categorization, these measures provide a view of the personal categorization behavior of non-professionals and illuminate biases in the production of 'folksonomies' due to tag production processes.

Gwizdka, Jacek and Spence, Ian (2007): Implicit measures of lostness and success in web navigation. In Interacting with Computers, 19 (3) pp. 357-369

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.

Gwizdka, Jacek and Spence, Ian (2005): Indirect assessment of web navigation success. In: Proceedings of ACM CHI 2005 Conference on Human Factors in Computing Systems 2005. pp. 1427-1430. Available online

Despite much research on hypertext and web navigation, relatively little is known about the relationship between web navigation strategies and success. We present two exploratory studies designed to explore the relationships between several web navigation metrics that are based on similarity to an optimal path to predict task success. The data suggest that the relationships between these measures depend on the particular web navigation task.

Gwizdka, Jacek and Spence, Ian (2005): Predicting outcomes of web navigation. In: Proceedings of the 2005 International Conference on the World Wide Web 2005. pp. 892-893. Available online

Two exploratory studies examined the relationships among web navigation metrics, measures of lostness, and success on web navigation tasks. The web metrics were based on counts of visits to web pages, properties of the web usage graph, and similarity to an optimal path. Metrics based on similarity to an optimal path were good predictors of lostness and task success.

Gwizdka, Jacek and Chignell, Mark (2004): Individual differences and task-based user interface evaluation: a case study of pending tasks in email. In Interacting with Computers, 16 (4) pp. 769-797

This paper addresses issues raised by the ever-expanding role of email as a multi-faceted application that combines communication, collaboration, and task management. Individual differences analysis was used to contrast two email user interfaces in terms of their demands on users. The results of this analysis were then interpreted in terms of their implications for designing more inclusive interfaces that meet the needs of users with widely ranging abilities. The specific target of this research is the development of a new type of email message representation that makes pending tasks more visible. We describe a study that compared a new way of representing tasks in an email inbox, with a more standard representation (the Microsoft Outlook inbox). The study consisted of an experiment that examined how people with different levels of three specific cognitive capabilities (flexibility of closure, visual memory, and working memory) perform when using these representations. We then identified combinations of representation and task that are disadvantageous for people with low levels of the measured capabilities.

FotoFile is an experimental system for multimedia organization and retrieval, based upon the design goal of making multimedia content accessible to non-expert users. Search and retrieval are done in terms that are natural to the task. The system blends human and automatic annotation methods. It extends textual search, browsing, and retrieval technologies to support multimedia data types.

I'm an enemy of what I call 'computer theology.' There's a class conflict out there. There's a techno-elite that lives in a different world.
