Summary: Web applications often need to present the user new information in the
context of their current activity. Designers rely on a range of UI elements and
visual techniques to present the new content to users, such as pop-ups, message
icons, and marquees. Web designers need to select which technique to use
depending on the centrality of the information and how quickly they need a
reaction. However, designers often rely on intuition and anecdotes rather than
empirical evidence to drive their decision-making as to which presentation
technique to use. This work represents an attempt to quantify these
presentation style decisions. We present a large (n=1505) user study that
compares 15 visual attention-grabbing techniques with respect to reaction time,
noticeability, annoyance, likability, and recall. We suggest glowing shadows
and message icons with badges, as well as more possibilities for future work.

Summary: Crowdsourcing platforms have been rapidly harnessed by organizations for
business uses, but enterprises continue to use traditional hierarchical forms
of work allocation within their own boundaries. Using crowd work models within
enterprises requires addressing enterprise-specific concerns such as how to
maintain focus on employees' primary work while providing the right incentives
to perform crowd work, how to promote wide employee participation while
preserving management oversight and control. We present a novel crowd work
system for the enterprise, the Market for Enterprise Tasks (MET), that
addresses these concerns via two novel features: an incentive system tied to
real-world dollars and multiple means of indirect control offered to the
management, especially the ability to limit the size of tasks performed in the
market. We have deployed MET in several groups within a large IT enterprise and
report on initial experiences.

Summary: Current location-based services (LBS) typically allow users to locate points
of interest (POI) in their vicinity but can detract from the user's emotional
experience of exploring a new location. In this paper, we examine how cues in
the form of popular music (musicons) can emotionally engage users and enhance
their experience of discovering nearby POIs serendipitously in unfamiliar
places. The primary contribution of this paper is a field study, in which we
evaluate the performance and emotional engagement of different types of
audio-based cues for directing users' attention to specific POIs. Musicons and
mixed-modality cues performed close to visual and speech cues, and
significantly better than auditory icons, for POI identification while creating
a much more pleasant and engaging user experience. We conclude that cues for
POI discovery need not always be as explicit as the baseline visual cues.
Indeed, the most challenging cues, auditory icons, led to a heightened sense of
autonomy.

Summary: We have designed and implemented Friendlee, a mobile social networking
application for close relationships. Friendlee analyzes the user's call and
messaging activity to form an intimate network of the user's closest social
contacts while providing ambient awareness of the user' social network in a
compelling, yet non-intrusive manner.

Summary: A growing number of websites are recognizing the value of personalization
based on a user's context and social network. As more websites become
personalized, the resulting experience for users can be rather fragmented. We
aim to facilitate a seamless Web personalization experience across websites by
enabling personalization to take place at the client and thus allowing personal
information about people to reside locally with people. If websites are to
script a personalization experience that draws on information held by the user,
it is imperative that this information be easily comprehensible by
heterogeneous websites. In this paper, we demonstrate how Semantic Web
technologies can be used to realize a vision of client-side Web
personalization. The contribution of this paper is an architecture that
demonstrates the feasibility of our approach and a prototype implementation
that establishes its viability.

Summary: A common perception is that there are two competing visions for the future
evolution of the Web: the Semantic Web and Web 2.0. A closer look, though,
reveals that the core technologies and concerns of these two approaches are
complementary and that each field can and must draw from the other's strengths.
We believe that future web applications will retain the Web 2.0 focus on
community and usability, while drawing on Semantic Web infrastructure to
facilitate mashup-like information sharing. However, there are several open
issues that must be addressed before such applications can become commonplace.
In this paper, we outline a semantic weblogs scenario that illustrates the
potential for combining Web 2.0 and Semantic Web technologies, while
highlighting the unresolved issues that impede its realization. Nevertheless,
we believe that the scenario can be realized in the short-term. We point to
recent progress made in resolving each of the issues as well as future research
directions for each of the communities.

Summary: A key challenge for dynamic Web service selection is that Web services are
typically highly configurable and service requesters often have dynamic
preferences on service configurations. Current approaches, such as
WS-Agreement, describe Web services by enumerating the various possible service
configurations, an inefficient approach when dealing with numerous service
attributes with large value spaces. We model Web service configurations and
associated prices and preferences more compactly using utility function
policies, which also allows us to draw from multi-attribute decision theory
methods to develop an algorithm for optimal service selection. In this paper,
we present an OWL ontology for the specification of configurable Web service
offers and requests, and a flexible and extensible framework for optimal
service selection that combines declarative logic-based matching rules with
optimization methods, such as linear programming. Assuming additive
price/preference functions, experimental results indicate that our algorithm
introduces an overhead of only around 2 sec.~compared to random service
selection, while giving optimal results. The overhead, as percentage of total
time, decreases as the number of offers and configurations increase.

Summary: The Web plays a critical role in hosting Web communities, their content and
interactions. A prime example is the open source software (OSS) community,
whose members, including software developers and users, interact almost
exclusively over the Web, constantly generating, sharing and refining content
in the form of software code through active interaction over the Web on code
design and bug resolution processes. The Semantic Web is an envisaged extension
of the current Web, in which content is given a well-defined meaning, through
the specification of metadata and ontologies, increasing the utility of the
content and enabling information from heterogeneous sources to be integrated.
We developed a prototype Semantic Web system for OSS communities, Dhruv. Dhruv
provides an enhanced semantic interface to bug resolution messages and
recommends related software objects and artifacts. Dhruv uses an integrated
model of the OpenACS community, the software, and the Web interactions, which
is semi-automatically populated from the existing artifacts of the community.
