Sure, by using Semantic MediaWiki or Wordpress’s SIOC plugin “I was already on the Semantic Web” – but a lot of data which is produced by such tools is not Linked Data but simple RDF. A closer look at all the datasets in the LOD cloud also reveals that none of them can be edited with an ease, except upcoming DBpedia Live which offers “real-time semantic web”.
Conclusio: So far most of the linked data in the LOD cloud was generated by DB2RDF mapping tools like D2R which can only be handled by semantic web experts and technicians. Don´t get me wrong – this is a very important basic layer for the LOD world.
All automatically generated datasets like DBpedia are kind of “highways” on the linked data map. Now it´s time to pave the side streets.
Just imagine, a teacher would like to publish his knowledge about Italian painters in a way it can be re-used as linked data. Should we tell him to “open an editor, to start typing RDF triples and to upload the file via FTP”?
When we started to design PoolParty in 2007 we had people in our minds who would like to contribute actively to producing data for the semantic web. People working for organizations with special domain knowledge are not only able to connect the dots from the linked data highways but also know how to customize such data for their own applications.
PoolParty 2.7 offers the following features and functionalities for such tasks:

From June 9 – 11, 2010 the EuroITV Conference discusses latest advances and research of media technology, HCI, media studies, and the content creation community. Tassilo Pellegrini talked to Lyndon Nixon, STI International, about the future role of semantic technologies in the television industry and how a Social Semantic Web might influence the traditional television experience.
NoTube is all about the future of television! We are seeing a significant shift in viewing patterns driven by the Web, which breaks the linear programming model and makes TV or video on demand a reality, whether it is being provided directly by the broadcasters or via a third party like Hulu or YouTube. The Web-based model taken up by viewers using their PC is being transferred back to the TV set in the lounge by IPTV applications running on Set Top Boxes or Internet TVs which come with Web access built into them. The strong interaction between the desires of users and technology has had its impact on the Web and as the gap between the Web and TV experience grows, we aim to translate features of the Web to TV, such as the personalised and community aspects. The NoTube European project puts the TV user back in the driver’s seat by generating user profiles from data the user creates on the Social Web, and in this way facilitating a personalised TV experience without an intrusive user profiling process.
With the hundreds of channels available via modern TV providers, content selection and dealing with the vast amount of TV-related information become significant challenges for users. TV metadata is created and distributed by a small group of people, as a result of the closed-source information exchange protocols that are the standard for providing electronic programme guide (EPG) data to users. Yet people often have several clusters of personal data on the Web, such as their profiles on social networks, or ratings of videos on YouTube and IMDB.
Analogously, there are many isolated clusters of broadcast data on the Web, such as broadcast data on EPGs and background information on Wikipedia. Within the NoTube vision context, we speculate that the conjunction of all these bits and pieces of data provide accurate information on someone’s interests, which is suitable for generating relevant recommendations on TV broadcasts. We see progress on opening up this data with open standards and APIs such as Google’s OpenSocial, Facebook’s OpenGraph, DBPedia, the BBC ontologies and FOAF. Further, we assume that Semantic Web technologies provide important building blocks for realizing this vision, as they enable the global identification mechanism of URIs and the means to define relations between data anywhere on the Web. By integrating these different pockets of data, we can provide TV viewers with personalised recommendations for their viewing.
Our primary focus is on open source and open standards, so for example we are extending the open source MythTV media centre to develop first scenarios of personalised EPGs. However, down the road there are clearly commercialisation opportunities.
Another scenario in the project looks at personalised advertising, which is clearly somewhere where there are revenue opportunities. However, we take user privacy very seriously, and one aspect we need to tackle in NoTube is the fine line between analysing user activity (in order to personalise their TV experience) and using that analysis commercially.
The third NoTube scenario involves pushing personalised news streams to TV viewers. Here, one could imagine that such a service could be packaged within a Pay TV offer, and used to give competitive advantage or justify a higher fee.
That’s true; in the traditional broadcasting sector the larger companies are extremely slow to adopt new technologies. However, I think Web video and TV has really shook up the sector – traditional broadcasters are seeing that they lose viewer share to Web-based offers and have been quick to take their video material to the Web. There is a clear demand for this, look at the viewing numbers for BBC’s iPlayer in the UK for example.
IPTV also means that new applications and services can be built on top of traditional TV. I think once the broadcasters see the added value of offering applications and services tied into the content of their programming – such as through semantic analysis of the program metadata, which NoTube is doing – they will be encouraged to support better these efforts. The BBC is really taking a lead in this, publishing a lot of their data already in RDF.
The NoTube workshop on Future Television: integrating the Social and
Semantic Web will take place at the EuroITV 2010 conference in Tampere, Finland on June 9, 2010.

Well, in the previous section we mentioned in passing that our technology was based on a synergistic approach, combining syntax, semantics and pragmatics. In this final part of the survey, we’ll explain just how we do this, and why our system yields unparalleled results. In doing so we’ll do our best to abstract away from the underlying mathematics and details of the machine-learning algorithms, and instead present the linguistic principles by which our algorithms work using examples. To wrap things up, we’ll end this review with a snapshot of what Digital Trowel’s Sentiment Analysis looks like in action.
Our technological approach begins with the observation that sentiment is conveyed on three interacting levels of increasing structural complexity. Namely the lexical, phrasal and semantic-event level of structure. We’ll explain.

We recently heard that Oracle 11G loaded RDF faster than we did. Now, we never thought the speed of loading a database was as important as the speed of query results, but since this is the sole area where they have reportedly been tested as faster, we decided it was time loading was addressed. Indeed, without Oracle to challenge us on query performance, we would not be half as good as we are. So, spurred on by the Oracular influence, we did something about our RDF loading.

PoolParty Team has released a Worpress plugin which imports SKOS thesauri and automatically generates a glossary for any given blog. This works as follows:
Please, take a look to the glossary of this blog as an example for this software.
Download Wordpress-Plugin: PoolParty Thesaurus for Wordpress 1.0 (or go to Wordpress plugin dircetory)
Thanks to Benjamin Nowack: The thesaurus is imported and into the system and is queried via ARC2.
Thanks to rduffy. His ‘Glossary’ Plugin inpired us, and we were able to develop this plugin on top of his ideas.
Works with PHP 5, MySQL 5 und ARC2

Frequently Asked Questions
Does my main PoolParty Thesaurus page need to be titled “Thesaurus”?
No. It can be called however you like. Just make sure to enter the page’s id into the plugin’s settings dashboard.
Does my child page need to be titled “Item”?
No. It can be called however you like.
How do I add a thesaurus item?
Therefore you need a SKOS thesaurus management tool like PoolParty. The glossary is generated automatically from the imported thesaurus.
How can I update the glossary?
Simply load the updated thesaurus again (admin area – settings -> PoolParty Thesaurus). The old thesaurus will be overwritten. New or updated concepts will be recognized immediately by the link generator.
