Semantic Web in Applications

26.5.2009. Talk at Webinale 2009. Webinale is a yearly conference and meetup of major web industry players in Germany. My talk was about semantic web for corporations. Creating mashups is a tedious task: each company provides a separate API with custom data format. The W3C Semantic Web RDF data format covers representation in XML, HTML-embedded Microformats, and in the database. Case studies collected by W3C show how the technology was used on the web, intranet and desktop, opening the door to artificial intelligence and a global web of data.

The Semantic Desktop - a new hope for Personal Information Management, Trends in eCommerce

1.12.2008. Trends in eCommerce is a lecture series at the Technical University of Vienna, organized by the E-Commerce Group. Abstract: With today's operating systems it is possible to store a file to a folder, but not to a project or a person. Applications do not share concepts of persons or projects. In the Semantic Web effort, the W3C has proposed standards for the management of metadata. This talk is about a merge of Semantic Web and Personal Computers resulting in the Semantic Desktop. Existing data sources are adapted to RDF, enabling integration across applications. Different projects aim at implementing the new paradigm, in the talk the open source frameworks published by the NEPOMUK project are presented.

Semantic Desktop Solutions,

22.10.2008. The Web of Data Practitioners Days is a new application-oriented event for Semantic Web practitioners and interested newcomers. It is intended to communicate the results of the past years‘ semantic systems activities to a broader audience, especially to practitioners from industry and academia. In a cooperative effort, four major Austrian institutions, which have actively been conducting research in that area throughout the past years, will set the stage for this event.

Participants will have the opportunity to see how semantic technologies may improve and enhance existing Web-based software systems and how the Web of Data will provide a completely new paradigm of managing globally interlinked information. As a result, attendees will get a better idea about the practical benefits of semantic solutions and researchers obtain valuable feedback for further research directions aiming at productivity and applicability of the existing technology for real-world use cases.

Our session on Semantic Desktop was by Leo Sauermann and Brian Davis from DERI. Abstract: A large fraction of our daily lives deals with digitally represented information: we communicate via email, instant messaging, weblogs; we order products and services via the World Wide Web; we consume digital media like movies and music; we organize our last holiday's pictures on our computers, and much more information is managed digitally. However, users of typical computer systems face similar problems as found on the Web: large amounts of information are stored in unstructured ways, and data are scattered across different systems. The problem increased over the last years through the plummeting cost of disk space, allowing us to store more and more information. Desktop operating systems provide no application-independent organizing scheme, the filesystem folder hierarchy is separated from the e-mail folders or contact categories. Thus it is hard to organize and retrieve personal information, both in the private and in the business domain. The Semantic Desktop is an environment where personal data of different kinds is annotated and related with machine-interpretable information. Semantic Web technology, like RDF, ontologies, and reasoning, are used to create a seamless personal space of information (PSI) that covers as many aspects of our digital life as possible, in order to make the personal computer a true extension to our brain. The Semantic Desktop session within the WOD-PD will focus on recent progress in this area. It will discuss existing infrastructures for semantic desktop environments, and it will demonstrate how such components are integrated into existing operating systems and applications. It will show how ontologies, information fusion, and automatic classification can be applied in the domain of personal information management (PIM), and how they can help to convey the user's mental model into digital form. Finally it will analyze how semantics can be injected into the user's normal workflow, and how intuitive user interfaces for semantic technologies can be designed.

Semantic Desktop, Webinale 2007

23.5.2007, Vortrag über Semantic Desktop und Semantic Web. Im Rahmen der Webinale 07 Konferenz. Folien.
Web-2.0-Anwendungen zeichnen sich durch die Wiederverwendung von Daten aus. Das vom W3C vorgeschlagene Datenformat "Semantic Web" kann dies erleichtern. Für den Benutzer ist es wichtig, in allen Anwendungen die gleiche Sicht auf seine Daten zu bekommen, Kategorien (Tags) die in einer Anwendung erstellt wurden, sollen überall wiederverwendet werden. In dieser Session wird ein Überblick gegeben, was Semantic-Web-Technologien sind und wie sie zur Datenintegration im Web und am Desktop eingesetzt werden können, was als "Semantic Desktop" bezeichnet wird.

The upcoming Social Semantic Desktop Platform, SRI, CA

07.09.2006, Talk about the upcoming Social Semantic Desktop Platform as a AI/SRI International's seminar, Palo Alto. Different research institutes are working on a vision titled "Semantic Desktop", a semantically enhanced desktop computer that allows us to access semantic web data and desktop data in a uniform way. The European Union Integrated Project NEPOMUK ( started in 2006 and intends to realize and deploy a comprehensive solution – methods, data structures, and a set of tools – for extending the personal computer into a collaborative environment, which improves the state of art in online collaboration and personal data management and augments the intellect of people by providing and organizing information created by single or group efforts. NEPOMUK brings together researchers, industrial software developers, and representative industrial users. In this talk you will get an introduction on the theory behind the Semantic Desktop, ontologies, databases, user interfaces and projects that work on this topic. Details about the current open-source implementations are presented and a demo is given. The lecture will finish with a discussion, where similarities and differences to the OpenIRIS project by SRI will be an important question.

Gnowsis Adapter Framework: Treating Structured Data Sources as Virtual RDF Graphs

10.11.2005, Galway, Ireland. Talk at the industry track of the 4th International Semantic Web Conference.

The integration of heterogenous data sources is a crucial step for the upcoming semantic web -- if existing information is not integrated, where will the data come from that the semantic web builds on? In this paper we present the gnowsis adapter framework, an implementation of an RDF graph system that can be used to integrate structured data sources, together with a set of already implemented adapters that can be used in own applications or extended for new situations. We will give an overview of the architecture and implementation details together with a description of the common problems in this field and our solutions, leading to an outlook on the future developments we expect. Using our presented results, researchers can generate test data for experiments and practitioners can access their desktop data sources as RDF graph.

World Usability Day - Bridges over the knowledge swamp

29.6.2005, Kaiserslautern. Invited talk at the World Usability Day. "Brücken über den Wissenssumpf - Wissensorientiertes Arbeiten durch den Semantic Desktop"

Increasing usability of current desktop computers by introducing Semantic view on files, e-mails, people and other items of daily life.

Betriebssysteme und moderne Desktop Anwendungen geben sich als Insellösungen. Die Tatsache, dass Menschen Computer verwenden um Ziele zu erreichen, Projekte zu organisieren oder mit anderen Menschen zu kommunizieren ist ist uns allen klar, nur nicht dem Betriebssytem - es kennt keine Ideen sondern nur Datei-Ordner. Durch aktuelle Entwicklungen im Web wird es möglich, Dateien und vieles mehr zu "taggen", zu Kategorisieren und zu vernetzen. Durch diese "semantische" Sicht ist es auch möglich, Desktop-Computer und Anwendungen näher an den Gedanken der Nutzer auszurichten. Diese semantischen Anwendungen sind auf integration ausgerichtet, auf kooperation untereinander und mit dem User. Gezeigt werden Beispielhafte Anwendungen und Designrichtlinien, die semantische Integration ermöglichen.

I-Know Conference: The Semantic Desktop – a Basis for Personal Knowledge Management

29.6.2005, Graz. Knowledge Management software is software that integrates. Existing Data sources, process flows, application features from office appliances have to be brought together. There are different standards, consisting of data formats and communication protocols, that address this issue. The WWW and Semantic Web are designed to work on a worldwide scale and define those standards. We transfer the web standards to the desktop szenario, a vision we call Semantic Desktop – a Semantic Web enhanced desktop environment. Central is the idea of taking know-how from the SemanticWeb to tackle personal information management. Existing desktop applications (email client,browser, office applications) are integrated, the semantic glue between them expressed using ontologies. We also present the open source project by the DFKI that realizes parts of this vision. It is based on a Semantic Web Server running as desktop service. It was used in experiments and research projects and allows others to experiment. Knowledge management applications can be built on top of it, reducing the implementation cost.

XML Clearinghouse - XML Kolloquium

24.4.2005, Berlin. Talk about The Gnowsis Semantic Desktop at the XML Kolloquium of the XML-Clearinghouse.

Tim Berners-Lee asked the Semantic Web community several times to "Build what is possible". We think that in anticipation of a world-wide Semantic Web, we have to use the technology on a single PC. Modern operating systems provide stone-age support for Personal Information Management. Linking the photo of a person to the address book entry of the same person is not possible as the system does not know the concept of persons, needless to say that one file cannot be placed in two folders. A categorization scheme (created in the file structure) cannot be used to organize bookmarks or emails - we always have to recreate our mental models again and again. This talk is about a radical merge of Semantic Web and Personal Computers resulting in the Semantic Desktop. It enables users to build and maintain a network of semantic links between resources, cross-application and cross-media. Existing data sources are converted into the Resource Description Framework and what today is known as a file or an email is tomorrow a resource represented in RDF and described through an ontology. The presentation will include our approach to on-the-fly data extraction and integration, based on RDF-Schemas and a Jena based framework. The architecture is implemented in the "" open source project and can be used as a basis for your own work and your information management needs.
