Graphingwiki enables the deepened analysis of the Wiki data by augmenting it with semantic data in a simple, practical and easy-to-use manner. Visualisation tools are used to clarify the resulting body of knowledge so that only the data essential for an usage scenario is displayed. Logic inference rules can be applied to the data to perform automated reasoning based on the data. Perceiving dependencies among network protocols presents an example use case of the framework. The use case was applied in practice in mapping effects of software vulnerabilities on critical infrastructures.Thu Jul 20 19:56:52 CEST 2006Proceedings of the First Workshop on Semantic Wikis -- From Wiki To SemanticsSemWiki2006-proceedingsJuneWorkshop on Semantic WikisSweetWiki : Semantic WEb Enabled Technologies in Wiki2006semwiki2006 swikig eswc2006 wiki semantic Wikis are social web sites enabling a potentially large number of participants to modify any page or create a new page using their web browser. As they grow, wikis suffer from a number of problems (anarchical structure, large number of pages, aging navigation paths, etc.). We believe that semantic wikis can improve navigation and search. In SweetWiki we investigate the use of semantic web technologies to support and ease the lifecycle of the wiki. The very model of wikis was declaratively described: an OWL schema captures concepts such as WikiWord, wiki page, forward and backward link, author, etc. This ontology is then exploited by an embedded semantic search engine (Corese). In addition, SweetWiki integrates a standard WYSIWYG editor (Kupu) that we extended to support semantic annotation following the "social tagging" approach made popular by web sites such as flickr.com. When editing a page, the user can freely enter some keywords in an AJAX-powered textfield and an auto-completion mechanism proposes existing keywords by issuing SPARQL queries to identify existing concepts with compatible labels. Thus tagging is both easy (keyword-like) and motivating (real time display of the number of related pages) and concepts are collected as in folksonomies. To maintain and reengineer the folksonomy, we reused a web-based editor available in the underlying semantic web server to edit semantic web ontologies and annotations. Unlike in other wikis, pages are stored directly in XHTML ready to be served and semantic annotations are embedded in the pages themselves using RDF/A. If someone sends or copy a page, the annotations follow it, and if an application crawls the wiki site it can extract the metadata and reuse them.Thu Jul 20 19:56:52 CEST 2006Proceedings of the First Workshop on Semantic Wikis -- From Wiki To SemanticsSemWiki2006-proceedingsJuneWorkshop on Semantic WikisFrom Wikipedia to Semantic Relationships: a Semi-automated Annotation Approach2006semwiki2006 swikig eswc2006 wiki semantic Thu Jul 20 19:56:52 CEST 2006Proceedings of the First Workshop on Semantic Wikis -- From Wiki To SemanticsSemWiki2006-proceedingsJuneWorkshop on Semantic WikisExtracting Semantics Relationships between Wikipedia Categories2006semwiki2006 swikig eswc2006 wiki semantic Wikipedia is the largest online collaborative knowledge sharing system, a free encyclopedia. Built upon traditional wiki architectures, its search capabilities are limited to title and full-text search. We suggest that semantic information can be extracted from Wikipedia by analyzing the links between categories. The results can be used for building a semantic schema for Wikipedia which could improve its search capabilities and provide contributors with meaningful suggestions for editing theWikipedia pages.We analyze relevant measures for inferring the semantic relationships between page categories of Wikipedia. Experimental results show that inlinks provide a better evidence of semantic connection in comparison to outlinks.Thu Jul 20 19:56:52 CEST 2006Proceedings of the First Workshop on Semantic Wikis -- From Wiki To SemanticsSemWiki2006-proceedingsJuneWorkshop on Semantic WikisA Collaborative Programming Environment for Web Interoperability2006semwiki2006 swikig eswc2006 wiki semantic We describe a new type of collaborative system that exhibits much of the simple, cooperative nature of a wiki, but allows dynamic sharing of functionality as well as of content. In contrast with traditional wikis, pages in this system are executable, and interoperate with each other by passing and returning data structures of known type, such as messages, URLs, or locations. This collaborative programming environment is well suited to retrieving and combining content available on the Web. Since code within pages can access any type of Web content, the environment provides a collaborative way to convert diverse, unstructured information into semantically annotated content that can be combined into new and useful services. We discuss how these ideas have been applied in WubHub, a prototype Web portal with a command-line interface.Thu Jul 20 19:56:52 CEST 2006Proceedings of the First Workshop on Semantic Wikis -- From Wiki To SemanticsSemWiki2006-proceedingsJuneWorkshop on Semantic WikisCreating and using Semantic Web information with Makna2006semwiki2006 swikig eswc2006 wiki semantic Thu Jul 20 19:56:52 CEST 2006Proceedings of the First Workshop on Semantic Wikis -- From Wiki To SemanticsSemWiki2006-proceedingsJuneWorkshop on Semantic WikisiMapping Wikis -- Towards a Graphical Environment for Semantic Knowledge Management2006semwiki2006 swikig eswc2006 wiki semantic iMapping is a visual technique for structuring information objects. It is based on research in the fields of visual mapping techniques, Information Visualisation and cognitive psychology. iMapping uses a Zooming User Interface to facilitate navigation and to help users maintain an overview in the knowledge space. An iMap is comparable to a large whiteboard where wiki-pages can be positioned like post-its but also nested into each other. Augmenting Wikis by providing spatial browsing and zooming facilities makes it easier to structure content in an intuitive way. Especially semantic wikis, which typically contain more fine-grained content, and stress the structure between information items, can benefit from a graphical approach like iMapping, that allows to display multiple such items and multiple wiki-pages in one view. This paper describes the iMapping approach in general, and briefly how it will be applied as a rich client front-end to the SemWiki engine.Thu Jul 20 19:56:52 CEST 2006Proceedings of the First Workshop on Semantic Wikis -- From Wiki To SemanticsSemWiki2006-proceedingsJuneWorkshop on Semantic WikisHarvesting Wiki Consensus - Using Wikipedia Entries as Ontology Elements2006semwiki2006 swikig eswc2006 wiki semantic One major obstacle towards adding machine-readable annotation to existing Web content is the lack of domain ontologies. While FOAF and Dublin Core are popular means for expressing relationships between Web resources and between Web resources and literal values, we widely lack unique identifiers for common concepts and instances. Also, most available ontologies have a very weak community grounding in the sense that they are designed by single individuals or small groups of individuals, while the majority of potential users is not involved in the process of proposing new ontology elements or achieving consensus. This is in sharp contrast to natural language where the evolution of the vocabulary is under the control of the user community. At the same time, we can observe that, within Wiki communities, especially Wikipedia, a large number of users is able to create comprehensive domain representations in the sense of unique, machine-feasible, identifiers and concept definitions which are sufficient for humans to grasp the intension of the concepts. The English version of Wikipedia contains now more than one million entries and thus the same amount of URIs plus a human-readable description. While this collection is on the lower end of ontology expressiveness, it is likely the largest living ontology that is available today. In this paper, we (1) show that standard Wiki technology can be easily used as an ontology development environment for named classes, reducing entry barriers for the participation of users in the creation and maintenance of lightweight ontologies, (2) prove that the URIs of Wikipedia entries are surprisingly reliable identifiers for ontology concepts, and (3) demonstrate the applicability of our approach in a use case.Thu Jul 20 19:56:52 CEST 2006Proceedings of the First Workshop on Semantic Wikis -- From Wiki To SemanticsSemWiki2006-proceedingsJuneWorkshop on Semantic WikisKaukolu: Hub of the Semantic Corporate Intranet2006semwiki2006 swikig eswc2006 wiki semantic Due to their low entry barrier, easy deployment, and simple yet powerful features, wikis have gained popularity for agile knowledge management in communities of almost all sizes. Semantic wikis strive to give entered information more structure in order to allow automatic processing of the wiki’s contents. This facilitates enhanced navigation and search in the wiki itself as well as simple reuse of information in external applications or for generating different views on the same information. This makes semantic wikis especially interesting for corporate intranet deployment, implementing the Semantic Intranet. In this paper, we will have a look at Kaukolu, an open source semantic wiki prototype, being deployed in a corporate intranet. External applications use information authored in Kaukolu, effectively forming a cluster of applications interacting and sharing data.Thu Jul 20 19:56:52 CEST 2006Proceedings of the First Workshop on Semantic Wikis -- From Wiki To SemanticsSemWiki2006-proceedingsJuneWorkshop on Semantic WikisA Semantic Wiki for Mathematical Knowledge Management2006semwiki2006 swikig eswc2006 wiki semantic Thu Jul 20 19:56:52 CEST 2006Proceedings of the First Workshop on Semantic Wikis -- From Wiki To SemanticsSemWiki2006-proceedingsJuneWorkshop on Semantic WikisTowards a Semantic Wiki-Based Japanese Biodictionary2006semwiki2006 swikig eswc2006 wiki semantic Thu Jul 20 19:56:52 CEST 2006Proceedings of the First Workshop on Semantic Wikis -- From Wiki To SemanticsSemWiki2006-proceedingsJuneWorkshop on Semantic WikisAnnotation and Navigation in Semantic Wikis2006semwiki2006 swikig eswc2006 wiki semantic Semantic Wikis allow users to semantically annotate their Wiki content. The particular annotations can differ in expressive power, simplicity, and meaning. We present an elaborate conceptual model for semantic annotations, introduce a unique and rich Wiki syntax for these annotations, and discuss how to best formally represent the augmented Wiki content. We improve existing navigation techniques to automatically construct faceted browsing for semistructured data. By utilising the Wiki annotations we provide greatly enhanced information retrieval. Further we report on our ongoing development of these techniques in our prototype SemperWiki.Thu Jul 20 19:56:52 CEST 2006Proceedings of the First Workshop on Semantic Wikis -- From Wiki To SemanticsSemWiki2006-proceedingsJuneWorkshop on Semantic WikisYlvi - Multimedia-izing the Semantic Wiki2006semwiki2006 swikig eswc2006 wiki semantic Thu Jul 20 19:56:52 CEST 2006Proceedings of the First Workshop on Semantic Wikis -- From Wiki To SemanticsSemWiki2006-proceedingsJuneWorkshop on Semantic WikisA Wiki as an Extensible RDF Presentation Engine2006semwiki2006 swikig eswc2006 wiki semantic Semantic wikis [1] establish the role of wikis as integrators of structured and semi-structured data. In this paper, we present Wikked, which is a semantic wiki turned inside out: it is a wiki engine that is embedded in the generic RDF editor Hyena. That is, Hyena edits (structured) RDF and leaves it to Wikked to display (semi-structured) wiki pages stored in RDF nodes. Wiki text has a clearly defined core syntax, while traditional wiki syntax is regarded as syntactic sugar. It is thus easy to convert Wikked pages to various output formats such as HTML and LaTeX. Wikked’s built-in functions for presenting RDF data and for invoking Hyena functionality endow it with the ability to define simple custom user interfaces to RDF data.Thu Jul 20 19:56:52 CEST 2006Proceedings of the First Workshop on Semantic Wikis -- From Wiki To SemanticsSemWiki2006-proceedingsJuneWorkshop on Semantic WikisWiki and Semantics: Panacea, Contradiction in Terms, Pressure for Innovation? - Some experiments and tracks towards Intelligence Amplifiers2006semwiki2006 swikig eswc2006 wiki semantic This paper examines the relative characteristics of wiki principles and of semantic systems. It first stresses some oppositions between these two approaches, and exposes the challenge of their reconciliation. We then make a detailed description of Ideliance, a "pure" semantic tool, and we set criteria to compare several existing semantic wiki systems. After a critical look at some of their features, we propose precise directions for cross-fertilisation of semantics and wikis, advocating for solid, long-term foundations.Thu Jul 20 19:56:52 CEST 2006Proceedings of the First Workshop on Semantic Wikis -- From Wiki To SemanticsSemWiki2006-proceedingsJuneWorkshop on Semantic WikisBringing the "Wiki-Way" to the Semantic Web with Rhizome2006semwiki2006 swikig eswc2006 wiki semantic Thu Jul 20 19:56:52 CEST 2006Proceedings of the First Workshop on Semantic Wikis -- From Wiki To SemanticsSemWiki2006-proceedingsJuneWorkshop on Semantic WikisTowards a Wiki Interchange Format (WIF) - Opening Semantic Wiki Content and Metadata2006semwiki2006 swikig eswc2006 wiki semantic Wikis are increasingly being used in world-wide, intranet and even in personal settings. Unfortunately, current wikis are data islands: people can read and edit them, but machines can only send around text strings without structure. Wiki migration, publishing from one wiki to another one and free choice of syntax hold back broader wiki usage. We define a wiki interchange format (WIF) that allows data exchange between wikis and between related tools. Different from other approaches, we also tackle page content and semantic annotations. The linking from formal annotations to parts of a structured text is analysed and described.Thu Jul 20 19:56:52 CEST 2006Proceedings of the First Workshop on Semantic Wikis -- From Wiki To SemanticsSemWiki2006-proceedingsJuneWorkshop on Semantic WikisReusing Ontological Background Knowledge in Semantic Wikis2006semwiki2006 swikig eswc2006 wiki semantic A number of approaches have been developed for combining wikis with semantic technologies. Many semantic wikis focus on enabling users to specify properties and relationships of individual elements. Complex schema information is typically not edited by the wiki user. Nevertheless, semantic wikis could benefit from taking existing schema information into account, and to allow users to specify additional information based on this schema. In this paper, we introduce an extension of Semantic MediaWiki that incorporates schema information from existing OWL ontologies. Based on the imported ontology, the system offers automatic classification of articles and aims at supporting the user in editing the wiki knowledge base in a logically consistent manner. We present our prototype implementation which uses the KAON2 ontology management system to integrate reasoning services into our wiki.Thu Jul 20 19:56:52 CEST 2006Proceedings of the First Workshop on Semantic Wikis -- From Wiki To SemanticsSemWiki2006-proceedingsJuneWorkshop on Semantic WikisThe ABCDE Format Enabling Semantic Conference Proceedings2006semwiki2006 swikig eswc2006 wiki semantic -We believe that the best way to present a narrative to a computer is to let the author explicitly create a rich semantic structure for the article during writing. – We propose an open-standard, widely (re)useable format, the ABCDE format for proceedings and workshop contributions that can be easily mined, integrated and consumed by semantic browsers and wikis. – There need not be an abstract in an ABCDE document - instead, the author denotes core sentences within the B,C and D sections, which are compiled through a macro to form a structured abstract. – We believe a LATEX stylesheet provides a suitable input format for providing authors with a semantic structure to work from. – We provide the abcde.sty LATEX file as an appendix to this paper. – Macros are provided to specify Dublin Core Elements, and to print a list of those that are specified. – Our section division into Background, Contribution, and Discussion is backed by a number of emperical studies. – We aim to work on different incarnations of this format and open it up to modification and development.Thu Jul 20 19:56:52 CEST 2006JuneWorkshop on Semantic WikisProceedings of the First Workshop on Semantic Wikis -- From Wiki To Semantics2006semwiki2006 swikig eswc2006 wiki semantic
