Fwd: content-wire : Human aspects and usability for next geration web technologies

Roberto and all
your workshop summary was posted to a newswire, see below-
should any of you be a subscriber to the service can pull the item up on
your
websites and intranets :-)

BTW, should anyone have cool stories they want publishes, please send them
to me for filing (I need them in some xml format, can send template)

Best

The adoption of Semantic Web technologies implies new challenges for user
interaction beyond those already posed by Web technologies and interactive
systems in general. The HSWI workshop held this summer in Madrid, explored
and evaluated good practices in interface design, with the aim to devise
possible recommendations for standardizing and consolidating knowledge and
good practices and produce a set of guidelines for semantic web developers,
to ensure the usability and promote reasonably functional user experiences
of the next generation of Semantic Web applications.

Although more and more semantic datasets are available, end-users have
difficulties to understand the data's paradigm and need appropriate tool
support to slice and dice the data to understandable parts or particular
resources.

At the workshop, (see link at the bottom of this story) researchers M.Voigt
et al proposed a novel approach to enable end-users to browse huge semantic
datasets, to detect, and to select interesting resources according to their
tasks. Their proposal includes two user studies adopting a web based
prototype that explore which visualisation and interaction techniques in
combination with automatic filters are well suited for novices.

J.M.Brunetti presented Visual Information-Seeking Mantra "Overview first,
zoom and filter, then details on demand" proposed by Shneiderman for lay
users to interact with semantic data. The first user task when dealing with
a dataset is to provide focussed overview so that the user can get an idea
about the overall structure of the dataset. Current semantic data
exploration tools provide little or no support for dataset overview. The
proposal is to reuse and adapt existing Information Architecture
components, well known to Web users, which are generated automatically from
semantic data. Navigation bars, site maps and site indexes are presented,
together with tree maps and other visualisation techniques for displaying
hierarchical data. Their work includes an evaluation with end-users.

J.Polowinski presented a way to model how to visualize data expressed as
RDF (resource description framework), the RDFS Visualization Language
(RVL), a declarative language for sharing visualization settings for RDF,
similar to CSS (cascading style sheets) for HTML. Unlike styling or
presentation languages for RDF or pure visualization languages, RVL
combines rich visual mapping capabilities with the direct awareness of
RDFS/OWL language constructs. The mapping definitions can be shared
together with the data to be visualized and can be also published as
uniform resource identifiers, which facilitates their extension and reuse.

B.H.Rodriguez and colleagues introduced Soa2mSituation, an ontology for
specifying multimodal interfaces, to facilitate the dynamic composition of
interactive features in multimodal systems in terms of roles, stereotypical
activities and perception. The ontology is based on the upper level
ontology DOLCE+DnS Lite. and it is based on the W3C's Multimodal
Interaction Architecture and Interfaces standard.

Task modeling is a core part of user centered requirements engineering,
something also relevant for semantic application modeling.To address the
gap in current tools which lack semantics based and user driven modeling
facilities and are not suitable for semantic mashup composition. V.Tietz,
presented a novel concept for a task modeling tool, supporting ontology
based requirements specification of enterprise mashups and presented a
prototype evaluated with users in a small study.

Visual representations are necessary for data analysis, especially for big
amounts of data. However, creating these visualizations is difficult for
end-users. A.Graves presented Visualbox, a web application that makes it
easier for non-programmers to create semantic data visualizations.
Visualbox has been tested with real users showing how the tool makes it
easier for users to create Linked Data-based visualizations, though users
still find it difficult to create the required SPARQL queries that retrieve
the data to be visualized.
