O'Brien, Maeve and Keane, Mark T. (2007): Modeling user behavior using a search-engine. In: Proceedings of the 2007 International Conference on Intelligent User Interfaces 2007. pp. 357-360. Available online
“A model of user-search-engine interaction is developed using the ACT-R cognitive architecture. We test, using an empirical evaluation, the model across different result orderings and relevance distributions, demonstrating that across a number of trials, the model approximates the characteristics of large numbers of users interacting with search-engines. These results are discussed in terms of their practical implications for search interfaces and ranking algorithms.”

Halvey, Martin J. and Keane, Mark T. (2007): Exploring social dynamics in online media sharing. In: Proceedings of the 2007 International Conference on the World Wide Web 2007. pp. 1273-1274. Available online
“It is now feasible to view media at home as easily as text-based pages were viewed when the World Wide Web (WWW) first emerged. This development has supported media sharing and search services providing hosting, indexing and access to large, online media repositories. Many of these sharing services also have a social aspect to them. This paper provides an initial analysis of the social interactions on a video sharing and search service (www.youtube.com). Results show that many users do not form social networks in the online community and a very small number do not appear to contribute to the wider community. However, it does seem those people who do use the available tools have much a greater tendency to form social connections.”

Halvey, Martin J. and Keane, Mark T. (2007): An assessment of tag presentation techniques. In: Proceedings of the 2007 International Conference on the World Wide Web 2007. pp. 1313-1314. Available online
“With the growth of social bookmarking a new approach for metadata creation called tagging has emerged. In this paper we evaluate the use of tag presentation techniques. The main goal of our evaluation is to investigate the effect of some of the different properties that can be utilized in presenting tags e.g. alphabetization, using larger fonts etc. We show that a number of these factors can affect the ease with which users can find tags and use the tools for presenting tags to users.”

Halvey, Martin J. and Keane, Mark T. (2007): Analysis of online video search and sharing. In: Proceedings of the Eighteenth ACM Conference on Hypertext and Hypermedia 2007. pp. 217-226. Available online
“It is now feasible to view video at home as easily as text-based pages were viewed when the Web first appeared. This development has led to the emergence of video search engines providing hosting, indexing and access to large, online video repositories. A key question in this new context is whether users search for media in the same way that they search for text. This paper presents a first step towards answering this question by providing novel analyses of people's linking and search behavior using a leading video search engine. Initial results show that page views in the video context deviate from the typical power-law relationships seen on the Web. However, more positively, there are clear indications that tagging and textual descriptions play a key role in making some video-pages more popular than others. This shows that many techniques based on text analysis could apply in the video context.”

Halvey, Martin, Keane, Mark T. and Smyth, Barry (2006): Time based patterns in mobile-internet surfing. In: Proceedings of ACM CHI 2006 Conference on Human Factors in Computing Systems 2006. pp. 31-34. Available online
“In this paper we investigate environmental factors that can result in users having different preferences and behaviors at different times of the day. An analysis is carried out of a large sample of user data for Wireless Application Protocol (WAP) browsing to determine whether user surfing patterns vary depending on time. We examine traffic on an hourly and daily basis, and show that accesses to particular categories of pages vary relative to time. We also build Markov models, which are temporal; to predict user navigation, and illustrate those predictive models are more accurate and beneficial to mobile Internet users than traditional methods. This analysis provides insight into improving the effectiveness and efficiency of navigation prediction.”

Halvey, Martin, Keane, Mark T. and Smyth, Barry (2006): Temporal rules for mobile web personalization. In: Proceedings of the 2006 International Conference on the World Wide Web 2006. pp. 839-840. Available online
“Many systems use past behavior, preferences and environmental factors to attempt to predict user navigation on the Internet. However we believe that many of these models have shortcomings, in that they do not take into account that users may have many different sets of preferences. Here we investigate an environmental factor, namely time, in making predictions about user navigation. We present methods for creating temporal rules that describe user navigation patterns. We also show the benefit of using these rules to predict user navigation and also show the benefits of these models over traditional methods. An analysis is carried out on a sample of usage logs for Wireless Application Protocol (WAP) browsing, and the results of this analysis verify our hypothesis.”

“Search engine results are usually presented in some form of text summary (e.g., document title, some snippets of the page's content, a URL, etc). Based on the information contained within these summaries users make relevance judgments about what links best suit their information needs. Current research suggests that these relevance judgments are in the service of some search strategy. In this paper, we model two different search strategies (the comparison and threshold strategies) and determine how well they fit data gathered from an experiment on user search within a simulated Google environment.”

“A predictive analysis of user navigation in the Internet is presented that exploits time-of-the-week data. Specifically, we investigate time as an environmental factor in making predictions about user navigation. An analysis is carried out of a large sample of user, navigation data (over 3.7 million sessions from 0.5 million users) in a mobile-Internet context to determine whether user surfing patterns vary depending on the time of the week on which they occur. We find that the use of time improves the predictive accuracy of navigation models.”

“While previous research into task analysis techniques has gone some way towards characterising techniques which allow one to move from a set of tasks in the world to some generalised model of these tasks, much more work needs to be done on this topic. The present paper puts forward a technique which attempts to deal with a number of issues which arise at this early stage of the design process. The proposed technique, called Preliminary Analysis for Design (PAD), characterises the process of forming a special type of generalised task model (GTM) in terms of three stages: (i) classifying the task world, (ii) generalising and organizing tasks and their elements to form a GTM and (iii) designing the GTM for representation in a subsequent system. It is also argued that this technique should be of some help in evaluating systems at an early stage in the design process.”
