UbisLabel & UnderscoreEncoding: a new Approach for Label-Encoding in the Multilingual World Wide Web
Dominikus Heckmann, Matthias Loskyll
Internet/WWW 2009 (submitted)
show abstract
Internationalization of identification names, for cities for instance, bears two major problems: which
language to choose for the label and which character set to choose for those characters that are not covered
by the ASCII character set. UbisLabel is a new approach to combine ideas for internationalizing the labels for
identifiers on the Semantic Web and the Web in general. We introduce an inline syntax to put several, possibly
multilingual labels into one string. UderscoreEncoding is able to represent the full Unicode code points shorter
than any existing UTF representation. It has been developed in order to represent special characters in an efficient
manner without using any characters apart from alphanumerical letters plus the underscore only. The idea is that
such encoded labels can be attached directly to the identifiers (like URIs) without the need to be further encoded
anywhere else in the Internet.
Visualization of Spatial Knowledge with Ontology Trees and Adaptable Search Result Grids in the Era of Web 3.0
Matthias Loskyll, Dominikus Heckmann, Christian Glahn
9th International Conference on Knowledge Management and Knowledge Technologies
show abstract
With the emerging trend ofWeb 3.0 and the resulting huge amount of usergenerated
semantically-enriched data, improved ways of knowledge visualization and
human computer interaction are needed. We present several techniques of visualizing
particularly spatial knowledge in largely scalable, clear structured ontology trees on
the web. In addition, we describe the representation of search results with a combined
approach consisting of Ajax-based grids and Google Maps.
UbisEditor 3.0: Collaborative Ontology Development on the Web
Matthias Loskyll, Dominikus Heckmann, Ichiro Kobayashi
Web 3.0: Merging Semantic Web and Social Web, Workshop at Hypertext 2009
show abstract
Ontologies continuously become larger and more complex,
and therefore more and more dicult to maintain, to edit
and to develop by one single person or a small group of
experts. The basic principle of Web 2.0, on the other hand,
is to use the willingness and knowledge of a huge community
of users to create rich user-generated content. The obvious
idea that comes to mind is to combine the technologies of the
Semantic Web with the trend of the Web 2.0. We present
UbisEditor 3.0, an easy-to-use web tool for the creation and
manipulation of structured collective knowledge represented
as ontologies. This web ontology editor is realized as part of
the UbisWorld project and already supports ontology editing
techniques like adding new concepts, renaming and deleting,
but also the creation of personalized ontology views.
Ideas for Collaborative Ontology Development on the Upcoming Web 3.0 Era

Towards Collaborative Ontology Development in the Upcoming Web 3.0 Era with UbisEditor
Matthias Loskyll, Dominikus Heckmann
11th Intl. Protégé Conference
show abstract
Collaborative ontology development combines the community approach of Web 2.0 with one of the key
technologies of the Semantic Web; therefore, this idea perfectly ts to the de nition of Web 3.0 by Wahlster
and Dengel [4]. In this demo description we present UbisEditor, an easy-to-use web tool for the creation and
manipulation of structured collective knowledge represented as ontologies, similar to the idea of WebProtege
[3]. This web ontology editor is realized as part of the UbisWorld project (http://www.ubisworld.org)
and already supports ontology editing techniques like adding new concepts, renaming, deleting, multilingual
label editing, but also the creation of personalized ontology views.
UbisWorld 3.0: a Semantic Tool Set for Ubiquitous User Modeling
Dominikus Heckmann, Matthias Loskyll, Rafael Math,

Demonstration description in online proceedings of First International Conference on User Modeling, Adaptation, and Personalization (UMAP 2009)
[ DOWNLOAD NOTE ]
show abstract
Ubiquitous User Modeling looks at personalization within
smart environments, tries to resolve problems of diversity of user modeling
techniques and representations by mediation of user models, and
bases on semantic standardization of user modeling enabling user modeling
data exchange and sharing by using a common user modeling ontology
and language. This paper describes the initial work done in the
UbisWorld 3.0 project, a tool set of semantic web and Web 2.0-like services
with the distributed management of scrutable user models, as well
as the foundations for a distributed user model ontology development.
This demonstration description previews only selected aspects of the new
data types, implementation issues and the user interfaces. The complete
system can be tested online as registered user at www.ubisworld.org.
