Using the open source software prototype Gnowsis, we evaluated the approach in a two month case study in 2006 with eight participants. Two participants continued using the prototype and were interviewed after two years in 2008 to show their long-term usage patterns. This allows us to analyse how the system was used for PIM. Contextual interviews gave insights on behaviour, while questionnaires and event logging did not. We discovered that in the personal environment, simple has-Part and is-related relations are sufficient for users to file and re-find information, and that the personal semantic wiki was used creatively to note information.

documents
based on Semantic Web ontologies and Web 2.0 services. We designed
and implemented
a process to normalize documents to RDF format, extract document topics
using Web 2.0 services and finally match extracted topics to a Semantic
Web ontology.
Due to ConTag we are able to show that the information provided by
Web 2.0 services
in combination with a Semantic Web ontology enables the generation
of relevant semantic
tag recommendations for documents. The main contribution of this work
is a
semantic tag recommendation process based on a choreography of Web
2.0 services.

standard and reference implementation for the Social Semantic Desktop.
We outline
the requirements and functionalities that were identified for a useful
Semantic Desktop
system and present an architecture that fulfills these requirements
which was acquired
by incremental refinement of the architecture of existing Semantic
Desktop prototypes.
The NEPOMUK project is primarily motivated by three real-life industrial
use-cases,
we briefly outline these and the processes used to extract required
functionalities from
the people working in these areas today, and we present a selection
of typical tasks
where the Semantic Desktop could be of benefit. ER - TY - CONF AU - Nadeem, Danish AU - Sauermann, Leo A2 - Pellegrini, Tassilo A2 - Schaffert, Sebastian T1 - From Philosophy and Mental-Models to Semantic Desktop research: Theoretical

Cognitive Science and Mental Models. The paper provides a philosophical
grounding
for the researchers in Personal Information Management (PIM). An overview
is given on
various philosophical aspects of computer-based activities. Discussions
on the theories
relevant to understand the goals for the Semantic Desktop community
are elicited.
Philosophical theories are not immediately transparent to the programmers,
but the
ideas discussed here are intended to emphasize a theoretical foundation,
with respect to
Semantic Desktop long term goals. The goal of this paper is to examine
the theories of
Philosophy and to provide a conceptual idea to design user-intuitive
Semantic Desktops.
The paper tries to induce scientific curiosity among the Semantic
Desktop researchers
as well as to develop the future Semantic Desktops to realize Weak
AI.

As a prerequisite for applying Semantic Web technologies to a certian domain of knowledge an ontological model of the domain is required. In the Gnowsis Semantic Desktop, the PIMO (Personal Information Model Ontology) addresses this problem by providing a generic lightweight ontology whose classes model the mian concepts involved in the daily activities of a person: places, organizations, persons, etc. But in order to be fully useful for a certain user, this generic model needs to be personalized and populated, adding more classes and concrete instances of the existent classes. As the process of manual population could be tedious and time consuming, in this paper we propose an alternative which tries to exploit the information that the user provides while performing Web searches. Apart from populating the PIMO, our approach is useful in resource annotation.

It supports the full range from informal note taking over semi-structured personal information management to formal knowledge models. With iMaps, users can easily go from overview to fine-grained structures while browsing, editing or refining the knowledge base in one comprehensive view. An iMap is comparable to a large white-board where information items can be positioned like post-its but also nested into each other. Spatial browsing and zooming as well as graphical editing facilities make it easy to structure content in an intuitive way. iMapping builds on a zooming user interface approach to facilitate navigation and to help users maintain an overview in the knowledge space. While a first implementation is being developed, iMapping is still in a conceptual stage. In this paper we describe the iMapping approach and how it tries to combine and extend the advantages of other approaches.

Existing ontology languages like RDF/S, OWL, SKOS and Topic Maps are very well suited for certain application areas, but do not fulfill some of the requirements given on the Semantic Desktop. In this report, a new ontology language, extending RDF/S, is proposed, the PIMO ontology language, which addresses the requirements of the Semantic Desktop and uses existing solutions as an inspiration to build a suitable solution. The language contains a core upper ontology, defining basic classes for things, concepts, resources, persons, etc. and also stops at these basic entities. Extending the ontology definitions of classes and relations is possible by PIMO-domain ontologies. The core application area of the PIMO-language is to allow individual persons to express their own mental models in a structured way, the different mental models can then be integrated based on matching algorithms or on domain ontologies. Based on the core upper ontology elements, each user can extend his personal mental model in an open manner.
Accompanying to the description of the ontology is a RDF/S version of the ontology language, created using the popular Protégé tool. An example of the mental model of a user is given, the fictional user "Paul" is further described. With the gnowsis-beta open source software, an implementation based on the PIMO language exists, that allows validating ontology files. A web-service for that will be provided soon. The ontology language, this document, the open-source reference implementation and the example documents can provide a stable basis for discussions on this topic and allow you to extend your own work.

On desktop computers, semantic software has to provide stable services and has to reflect the personal view of the user. Our approach to ontologies, the Personal Information Model PIMO allows to create tagging services like del.icio.us on the desktop. A semantic wiki allows further annotations. Continuous evaluations of the system helped to improve it. These results were created in the EPOS research project and are available in the open source projects Aperture, kaukoluwiki, and gnowsis and will be continued in the Nepomuk project. By using these components, other developers can create new desktop applications the web 2.0 way. ER -
