a linked data driven web page rendered by OntoWiki site extension
The semantic data wiki OntoWiki can be used as a Content Management System to render and manage content of certain types. According to 'eat you own dog food', the aksw.org web page is an example for this approach.
{{toc tag="ul" depth="3"}} # Big-Picture This web page consists of linked data enabled resources. Each resource has a specific HTML5 representation (besides its RDF representation). This HTML representation is rendered by using a template and fill its variable parts with the content from these sources: * values (Literals) of specific attributes from the resource * output of helper markup (see below) * content rendered from sub-templates # Resources and Properties The following attributes and classes are used by the templates. ## Classes Currently, there are templates for the following classes of resources: * foaf:Document: a basic web page without specific lists and queries * aiiso:ResearchGroup: a (sub) research group with lists of member, research areas and projects * foaf:Person: a person with lists of projects and research areas * foaf:Project: an AKSW project. Can be a funded, a community or an open-source project. ## Properties These properties can be applied to all resources: * rdfs:label: This is the overall headline, name or title of a resource. * site:menuLabel: If the resource title is too long for the menu, use this property in addition to rdfs:label. * site:content: The main content property. The literal value should be of datatype sysont:Markdown. * dcterms:abstract: This is a plain text attribute (no markup). The content of this attribute is used in extended lists and build the header of the resource as a first summary paragraph. * aksw:hookline: This a less than 100 character description of the resource. Hooklines are especially important for projects to advertise them in lists and on top of the project page. * sioc:feed: Use this object property to relate a RSS or Atom feed to this resource. The content of this feed is shown in the right side content column. In addition to the general properties, these class specific properties can be used: * for Projects: foaf:homepage * for Groups: aksw:researchAreas, foaf:member * for Person: foaf:name, foaf:currentProject, foaf:pastProject, foaf:mbox, aksw:room, aksw:publicationTag (for the publication list) # Main Content The suggested markup language to write pages is [Markdown](http://daringfireball.net/projects/markdown/). Markdown is a text-to-HTML conversion language for web writers. Markdown is intended to be as easy-to-read and easy-to-write as is feasible. All details on Markdown syntax are available on the [syntax page](http://daringfireball.net/projects/markdown/syntax). Besides its readability, one main advantage of Markdown is its integration with HTML. Wherever you need HTML markup, you can use it without any quote or special syntax as [inline HTML](http://daringfireball.net/projects/markdown/syntax#html). Have a look at the sources of this document to copy/paste specific style elements which you want to reuse, or add new stuff and share it. The main content of each resource is saved as a Literal object with the attribute site:content. See the description of this property for details about its usage. In general: All attributes and classes have a proper documentation, so you just need to click on them inside of OntoWiki for more details. ## Helper Markup Helper markup is used in the same way as wiki actions. The general syntax of a helper tag is: `{{tagname p1="value1" ... "pX"="valueX"}}`. The following helper exists so far. ### Table of Content helper The `toc` helper creates an javascript generated table of contents at the position where the helper tag was written. The following options can be used * `tag`: the toc type can be `ol`, `ul` or `div`, default is `ol` * `startlevel`: which heading level to start? default is `1` * `depth`: how many TOC levels you want? default is `2` Examples (use a single `=` instead of `==`): * `{{toc depth=="2"}}` ### link helper The `link` helper creates an internal page link to a specific resource. If you need to link to an aksw.org resource, you should use this helper instead of using plain HTML-links or Markdown link syntax. Possible parameters are: * `literal`: search for this literal and link to its resource (the first found). * short form: `l` * 'uri': instead of searching for a resource, use the given qname or uri string * short form: `r` * `property`: search only for literals of the given property. * short form: `p` * `text`: instead of using the resource title, use the given string as link text. * short form: `t` Examples (use a single `=` instead of `==`): * `{{link uri=="http://aksw.org/About"}}` * result: {{link uri="http://aksw.org/About"}} * `{{link r=="foaf:Person"}}` * result: {{link r="foaf:Person"}} * comment: use qnames where possible, use short values * `{{link literal=="Projects"}}` * result: {{link literal="Projects"}} * `{{link text=="our projects" literal="Projects"}}` * result: {{link text="our projects" literal="Projects"}} * `{{link property=="site:menuLabel" literal="About"}}` * result: {{link property="site:menuLabel" literal="About"}} * `{{link literal=="MyPage"}}` * result: {{link literal="MyPage"}} * comment: no links to non existing resources * `{{link uri=="no/uri"}}` * result: {{link uri="no/uri"}} * comment: wrong usage is indicated in this way, a mouseover tooltip over the error gives you more information about the problem * `{{link p=="foaf:nick" l="Seebi" t="my page"}}` * result: {{link p="foaf:nick" l="Seebi" t="my page"}} * comment: Example with short parameters, qname and given link text ## Style Elements There are specific style elements as two column sections or tables which you can add to your documents by using HTML markup. ### Multi Columns first columns ... ... second column ... ... ### Tables Use standard HTML tables with table head and cell tags to achieve a look like this Tabelle Head Tabelle Head Development methods, tools and applications applications adaptive Knowledge Engineering # Navigation Structures Menus are rdf:Seq resources of type aksw:Navigation. The rdf properties `rdf:_1` till `rdf:_x` are used to arrange an ordererd list of resources which a used to render a navigation menu. Currently, we have these navigation resources: * {{link literal="Main Navigation"}} * {{link literal="Top Navigation"}}
This example page demonstrates some features of this linked data enabled web page including features from the OntoWiki site extension, the AKSW site-specific additions as well as Markdown and helper markup in general.

Convert a natural language expression to a SPARQL query
The underlying idea is to convert a natural language expression to a SPARQL query, which can then retrieve the answer of a question from a given triple store.
Most knowledge sources in the Web of Data were extracted from either structured or semi-structured data. Although they are an invaluable resource for structured knowledge, they consist of less than 20% of the information available on the Web. The idea behind BOA is to use the knowledge available in Linked Data Web to extract even more information from the Web. The potential of the approach is immense, as it could promote the Linked Data Web to the lingua franca for a large number of applications including machine translation, named entity recognition and speech generation.

An Android-based social web client as well as a contacts provider, which integrates your distributed FOAF/WebID social network into your mobile phone.
a light-weight methodology for low-cost knowledge engineering by a massive user base
Although structured data is becoming widely available, no other methodology – to the best of our knowledge – is currently able to scale up and provide light-weight knowledge engineering for a massive user base. Using NKE, data providers can publish flat data on the Web without extensively engineering structure upfront, but rather observe how structure is created on the fly by interested users, who navigate the knowledge base and at the same time also benefit from using it. The vision of NKE is to produce ontologies as a result of users navigating through a system. This way, NKE reduces the costs for creating expressive knowledge by disguising it as navigation.
NLP2RDF is a LOD2 Community project that is developing the NLP Interchange Format (NIF) .

Use JavaScript RDFa Widgets for Model/View Separation inside Read/Write Websites
As more and more websites start to embed RDFa content in their web application view, the need arises to provide a more extensive way for viewing and editing this semantic content independently from the remainder of the application. We present a JavaScript API that allows the independent creation of editing widgets for embedded RDFa, which adds a new edge to Web development in the context of the Semantic Web. As an addition, the API also provides sound update methods that allow on-the-spot model synchronization between client and server.
RDFaCE is an RDFa Content Editor based on TinyMCE. It supports different views for semantic content authoring and uses existing Semantic Web APIs to facilitate the annotation and editing of RDFa contents.
is an editing solution for distributed and syndicated structured content on the World Wide Web
The system is able to extract structured information from RDFa-enhanced websites and to create an edit form based on this data. To this end, we make use of semantics-aware editing widgets that hide most of the RDF data model from the user, thus allowing more people to author semantic content. If the embedded data does not suffice to create a rich user-supporting editing view, the underlying Semantic Web infrastructure is used to retrieve additional schema-related information about the elements used.
Using the Web of Data for Evaluating the Research-Disease Disparity
The ReDD-Observatory is a project to evaluate the disparity between active areas of biomedical research and the global burden of disease using Linked Data and data-driven discovery.
* Partners: Punk.Netservices GmbH (A), OpenLink Software Ltd. (UK), Netresearch GmbH & Co. KG (D), Digital Trowel Inc. (IL) * Duration: 2010–2012 * Funding Programme: Eurostars
SCMS aims at combining automatic knowledge discovery and participative, end-user-driven knowledge curation and extension techniques through Social Semantic Web approaches so as to create novel applications in Enterprise Knowledge Management and real-time News Mining.
Semantically INterpreting user query towards question-Answering
Knowledge bases published on the Web of Data can be used to answer challenging questions about a wide range of topics. They usually offer a SPARQL endpoint, which can be queried by the user. However, a novice user needs to acquire both knowledge about the underlying ontology and proficiency in formulating SPARQL queries in order to actually formulate a SPARQL query. In this project, we are working on constructing SPARQL queries based on user-supplied keywords. As a result ordinary users are empowered to formulate relatively expressive queries without knowledge of SPARQL and the underlying ontology structure.
Adding a social dimension to the Linked Data Web
The Semantic Pingback mechanism is an extension of the well-known Pingback method, a technological cornerstone of the blogosphere, thus supporting the interlinking within the Data Web.
