- KonferenzbeitragAlternative Searching Services: Seven Theses on the Importance of "Social Bookmarking"(The Social Semantic Web 2007 – Proceedings of the 1st Conference on Social Semantic Web (CSSW), 2007) Graefe, Gernot; Maaß, Christian; Heß, AndreasIn recent years social bookmark systems like del.icio.us Furl have become increasingly popular. These systems sometimes are regarded as alternatives to algorithmic search engines like Google. In this paper we develop seven theses on the potential of these systems in order to establish a conceptual basis for future research in this area. Thereby it becomes clear that social bookmarking systems complement rather than threaten algorithmic search engines.
- KonferenzbeitragCollaborative Metadata for Geographic Information(The Social Semantic Web 2007 – Proceedings of the 1st Conference on Social Semantic Web (CSSW), 2007) Maué, PatrickRetrieval of web-based geographic information (GI) for spatial decision- making processes can benefit from emerging semantic technologies. Ontology-supported metadata, collaboratively created by a social network of spatially-aware users, ensures efficient and precise discovery of maps published with the help of catalogs. The creation and maintenance of the metadata is driven by two forces: on the one hand experienced catalogers who ensure consistency and quality, on the other hand catalog users who continuously adapt and extend the metadata. We discuss the requirements for a catalog for GI which is able to capture the semantics emerging within a community and apply the results to the registered metadata.
- KonferenzbeitragCollaborative Web-Publishing with a Semantic Wiki(The Social Semantic Web 2007 – Proceedings of the 1st Conference on Social Semantic Web (CSSW), 2007) Landefeld, Rico; Sack, HaraldSemantic wikis have been introduced for collaborative authoring of ontologies as well as for annotating wiki content with semantic meta data. In this paper, we introduce a different approach for a semantic wiki based on an ontology meta model customized especially for the deployment within a wiki. For optimal usability client- side technologies have been combined with a simple semantic query language. Text fragments of a wiki page can be annotated in an interactive and rather intuitive way to minimize the additional effort that is necessary for adding semantic annotation. Thus, the productivity and efficiency of a semantic wiki system will open up for non expert users as well.
- KonferenzbeitragDiscovering Unknown Connections – the DBpedia Relationship Finder(The Social Semantic Web 2007 – Proceedings of the 1st Conference on Social Semantic Web (CSSW), 2007) Lehmann, Jens; Schüppel, Jörg; Auer, SörenThe Relationship Finder is a tool for exploring connections between objects in a Semantic Web knowledge base. It offers a new way to get insights about ele- ments in an ontology, in particular for large amounts of instance data. For this reason, we applied the idea to the DBpedia data set, which contains an enormous amount of knowledge extracted from Wikipedia. We describe the workings of the Relationship Finder algorithm and present some interesting statistical discoveries about DBpedia and Wikipedia.
- KonferenzbeitragExploring the Netherlands on a "Semantic Path"(The Social Semantic Web 2007 – Proceedings of the 1st Conference on Social Semantic Web (CSSW), 2007) Martin, MichaelThis poster gives an overview about the web application "vakantieland.nl", a Dutch Internet portal in the tourism domain. The core functionality is to provide information about holiday destinations, accommodation and other tourism related points-of-interest as well as a corresponding visualization with a mapping service. Because of the underlying semantic data structures and alternatively generated RFD output, vakantieland.nl can be considered to be a Semantic Web application. Its realization and functionalities, social aspects and furthermore an outlook about future development work constitute the main part of the poster.
- KonferenzbeitragGalaxy: IBM Ontological Network Miner(The Social Semantic Web 2007 – Proceedings of the 1st Conference on Social Semantic Web (CSSW), 2007) Judge, John; Sogrin, Mikhail; Troussov, AlexanderMany applications of the semantic web and Web 2.0 aim to empower the knowledge worker. These applications however, do not allow the user to combine all of his/her social and semantic information into a single resource which allows data to be processed, managed and enhanced automatically. In our demo we will present a number of demo applications based on Galaxy, IBM’s ontological network miner, which was designed to work with such resources to enhance the capabilities of a number of applications in social semantic computing. Galaxy is a highly efficient, scalable system which can be easily built into an application and can be optimised to suit a user’s preferences or to take into account the needs of a particular task or application.
- KonferenzbeitragHello Data Web - Exposing the Data Web(The Social Semantic Web 2007 – Proceedings of the 1st Conference on Social Semantic Web (CSSW), 2007) Idehen, Kingsley
- KonferenzbeitragIMAGENOTION - Collaborative Semantic Annotation of Images and Image Parts and Work Integrated Creation of Abstract: Ontologies(The Social Semantic Web 2007 – Proceedings of the 1st Conference on Social Semantic Web (CSSW), 2007) Walter, Andreas; Nagypal, GaborIn this paper, we present the ImageNotion tool that allows for the semantic annotation of images and image parts together with the maturing of ontologies in a work integrated environment. The tool uses our ImageNotion methodology for ontology development.
- KonferenzbeitragImplementing SPARQL Support for Relational Databases and Possible Enhancements(The Social Semantic Web 2007 – Proceedings of the 1st Conference on Social Semantic Web (CSSW), 2007) Weiske, Christian; Auer, SörenIn order to make the Semantic Web real we need the infrastructure to store, query and update information adhering to the RDF paradigm. Such infrastructure can be developed from scratch or benefit from developments and experiences made in other science & technology realms such as within the database domain. For querying RDF data the World Wide Web Consortium released a Working Draft for the SPARQL query language. A large portion of the Web is meanwhile driven by server-side Web applications. PHP is the scripting language most widely used for Web applications. In this paper we present our PHP implementation of the SPARQL standard directly interacting with an underlying database system. The approach is based on the rationale of pushing as much work into the RDBMS as possible in order to profit most from the query optimization techniques developed for relational database systems. The article includes an evaluation of the performance and standard compliance, surveys limitations we discovered when using SPARQL for the implementation of real-life Semantic Web applications and suggests extensions to the SPARQL standard in order to solve these obstacles.
- KonferenzbeitragMapping Cognitive Models to Social Semantic Spaces – Collaborative Development of Project Ontologies(The Social Semantic Web 2007 – Proceedings of the 1st Conference on Social Semantic Web (CSSW), 2007) Riechert, Thomas; Lohmann, SteffenIn this paper, we present an approach that applies concepts from the areas of Social Software and Semantic Web to application development. We start with a short introduction into Semantic Based Requirements Engineering. Then, we present an ontology for capturing requirements and related information. Based on this ontology, we describe how stakeholders are enabled to directly participate in requirements elicitation and to collaboratively create a project ontology. Finally, we report about the application of the presented approach in a use case from the e-government domain.
