    [BibTeX] [Abstract]

    Following up on work presented at IESD 2012 introducing the paradigm of multifocal exploration of semantic data, the present paper reports on two user studies of prototypes that instantiate parallel faceted browsing—a generalization of faceted browsing that enables multiple interrelated queries and their results to be displayed at the same time. In the first study, with the “World Design Capital Helsinki” demonstrator, 100 participants remotely tested the prototype for a few minutes each, performing simple tasks without explicit instructions about how to operate the system. The majority of participants were able to understand the system after engaging in trial and error, but even the successful ones found it rather unfamiliar-looking at first; and a feeling of unfamiliarity appears to have discouraged the less successful subjects from exploring the interface in the first place—a result that indicates a need to provide explicit explanation and motivation for the benefit of users who are less inclined to engage in trial and error. The participants spontaneously noticed a variety of benefits of parallel faceted browsing relative to existing interaction paradigms. In the second study, which involved a different instantiation of parallel faceted browsing in the domain of food and recipes, results concerning learnability and perceived benefits were generally consistent with those of the first study. Subjective ratings revealed mostly positive evaluations of the demonstrator, though a minority of participants stopped working with it before they perceived its benefits.

    The widely used paradigm of faceted browsing is limited by the fact that only one query and result set are displayed at a time. This demonstrator introduces an interaction design for parallel faceted browsing that makes it easy for a user to construct and view the results of multiple interrelated queries. The paradigm offers general benefits for a variety of application areas.

    [BibTeX] [Abstract] [Download PDF]

    The data exploration paradigm of faceted browsing has been applied successfully in many systems that provide access to either semantic data or more conventional databases. A general limitation is that the user can examine the results for only one query i.e., one combination of facet value constraints at a time. But there are many everyday tasks for which it is desirable to be able to compare the results for two or more queries or to refine several queries incrementally in parallel. In this paper, we introduce parallel faceted browsing which enables the user to construct a tree of queries and associated results whose structure captures the commonalities among the queries. The entities represented in this demonstrator are events associated with Helsinki’s role as the 2012 World Design Capital, as well as related events from other data sources that took place in Finland during the same period. Semantic Web technologies are used in the back-end for representing and reconciling those heterogeneous data sources. Several types of task have been identified in which parallel faceted browsing offers added value. Careful attention has been paid to interaction design with the goal of making this inherently more complex paradigm as intuitively understandable as normal faceted browsing. Readers are encouraged to try the EventMAP demonstrator itself at http://eventmap-ui.appspot.com/.

    [BibTeX] [Abstract] [Download PDF]

    Research in the semantic web community has given rise to some powerful methods for visualizing events and related media—mostly in terms of interactive timelines—and for enabling users to interact with these visualizations. The present paper aims to advance this line of research in two ways: a by developing interactive visualizations of event hierarchies of essentially arbitrary depth and size, which are more natural than timelines in the case of complex events that comprise subevents at various levels; and b by supporting forms of interaction that go beyond the usual activities of browsing and searching for events and related media, supporting additionally the sharing and annotation of media and the provision of interactive illustrations of narrative texts.

    Even the most sophisticated automatic recognition of events must often be paired with an appropriate design of the users’ interaction with those events. This paper presents three presumably typical use cases and associated interaction design proposals, which illustrate (a) how untrained users can benefit from the organization of media in terms of complex events; (b) how they can have their own media categorized in this way without having to invest much effort; and (c) how they can even create complex event instances with novel structures, without having to think explicitly about event structures.

    Recent years have seen an explosion in the number of on-line communities; a person looking for a community for some purpose may have hundreds to choose from. Helping users make such choices therefore constitutes an interesting appli- cation area for recommender systems, which has so far been explored only sporadically. To facilitate further exploration of this area, we discuss the following questions: What goals can a user be pursuing when looking for a community? What sorts of information about communities can be available that could be used by a recommender system? The answers to the second question are based on a systematic examination of a sample of 15 communities on three web-based platforms.
