    KiWi - a platform for Semantic Social Software KiWi - a platform for Semantic Social Software Presentation Transcript

    • KiWi – A platform for semantic social software 4th Semantic Wiki Workshop at ESWC09 Heraklion, June 2009 Dr. Sebastian Schaffert Salzburg Research Forschungsgesellschaft sebastian.schaffert@salzburgresearch.at http://www.kiwi-project.euhttp://planet.kiwi-project.eu
    • KiWi Vision 12/03/08 Joint KiWi Workpackage Meeting, © 2008,Sebastian Schaffert, Salzburg Research
    • “Some people say information is power. Baloney. Information sharing is power!” - Vint Cerf, Google
    • The Wiki Philosophy | core wiki principles: | anyone can edit and contribute | easy to use, low technological barrier | content is easy to link (and thus related) | versioning (information does not disappear) | support for all kinds of media | these principles are not restricted to wikis as in “wiki engine”, they apply to most social software systems!
    • Breaking System Boundaries | the KiWi system offers the core fuctionalities required by social software systems: | representation of many different content formats | easy linking between content items | versioning and change tracking of content items | annotation of content with meta-data | rating and commenting of content by users | user management, user profiles, social networking | personalisation and context adaptation | searching and querying … and more to come (information extraction, reasoning, ...)!
    • Breaking Information Boundaries | integration of different kinds of content beyond linking | same content shared and exchanged between many different applications and even systems
    • Putting the User in the Centre | tailor presentation and functionality to information needs of the user | different ways of accessing information, depending on context and personal preferences | personalisation based on user model (previous activities, …) | use information extraction and user tracking for calculating recommendations | allow users to modify the user interface by adding new widgets, custom layouts, semantic forms
    • KiWi System: a platform following these principles | social media applications build on top of this platform and can benefit from | sharing content between different kinds of applications (Wiki page can be displayed in TagIT, …) | sharing functionality between different kinds of applications (editing, versioning, tagging, …) | interoperability with other systems due to semantic web data formats
    • KiWi Applications 12/03/08 Joint KiWi Workpackage Meeting, © 2008,Sebastian Schaffert, Salzburg Research
    • KiWi Applications: Wiki
    • KiWi Applications: TagIT
    • KiWi Applications: Dashboard
    • The KiWi System 12/03/08 Joint KiWi Workpackage Meeting, © 2008,Sebastian Schaffert, Salzburg Research
    • KiWi Architecture
    • Content Item | central entity in the data model, used for representing wiki pages, images, comments, blog posts, locations, … | represents human readable content (text, media) as well as associated metadata (RDF triples) | semi-structured RDF used to represent all relevant structured data of a content item and relations to other items, e.g. geo information, EXIF data, authorship, replies, …
    • Model Layer: KiWiEntityManager + KiWi Façades | central component to access all KiWi data | offers transactions, revisions, and storing data in relational database, triple store, and search index | allows to create KiWi Façades around content items | KiWi Façades: | dynamic, application-specific Java views on content + metadata | one content item shared between many different applications | implemented as Java interfaces with annotations
    • KiWi Services | offer core functionalities of the KiWi platform | ContentItemService: loading, updating, storing content items | TaggingService: adding / removing (semantic) tags | SolrService: facetted (semantic) searching | OntologyService: maintaining ontologies | SKOSService: maintaining SKOS thesauruses | … | implemented as EJB 3.0 stateless beans (mostly) or Seam application-scoped components | some of the functionality also exposed as RESTful web service
    • KiWi Actions | backing components for user interface functionality: | ViewAction, EditAction, TaggingAction in Wiki | StreamOfActivitiesAction in Dashboard | ExplorerAction and TaggerAction in TagIT | mostly implemented as Seam stateful components scoped to conversation, page or event
    • Conclusion & Perspectives 12/03/08 Joint KiWi Workpackage Meeting, © 2008,Sebastian Schaffert, Salzburg Research
    • Conclusion | knowledge management + wiki philosophy + semantic web = KiWi | KiWi system – a platform for building flexible semantic social media applications following the “wiki principles” | provides all the core functionalities | allows sharing of content between applications | allows to realise the KiWi knowledge management idea | several applications exist to demonstrate the feasibility: | (Semantic) Wiki – collaborative creation of content | TagIT – geolocating content | Dashboard – personal startpage
    • Perspectives | more functionalities: | inclusion of Sun’s “community equity” system | sophisticated personalisation features (recommendations, user interface personalisation) | sophisticated information extraction: automatic extraction of metadata, suggestion of tags and related content | rule-based reasoning: users will be able to write their own rules that influence how the system behaves | more applications: | KiWi Blog | Social Networking Platform | …
