Linked Data at the BBC: Connecting Content around the Things that matter to Audiences

cache_23146737This year SEMANTiCS conference presents some brilliant speakers. As there is Sofia Angeletou with her keynote on the 2nd generation Linked Data Strategy at the BBC.

Quote: “The vision of semantic publishing in the BBC has shifted from supporting high profile events to connecting the BBC’s content around things that matter to the audience. To this end, we have increased the application of linked data to domains other than sports such as news, education and music with the intention that the content we produce can be reused and discovered through a multitude of channels.”

In her keynote, Sofia will outline the technological and cultural factors that have influenced the BBC’s adoption of linked data. A talk reflecting the early assumptions BBC made their effects on the development of the platform and they way BBC are addressing them now.
A talk people who are working in the media and publishing industry should not miss and one of several highlights the completely re-brushed SEMANTiCS conference will provide to you.

Register for SEMANTiCS 2014 in Leipzig / Germany.

Online checker for SKOS vocabularies now available

Create better SKOS vocabularies
quality_check_finishedPoolParty team likes to announce the availability of the new online vocabulary quality checker for SKOS vocabularies. It finds over 20 kinds of potential quality problems in controlled vocabularies that are expressed using SKOS. The service is based on the qSKOS open-source tool.
The main features of the service are:
  • No need for registration – you can log in with your existing accounts at Google, Xing, LinkedIn or Twitter
  • Upload and check as many vocabularies you like (100MB maximum size for each vocabulary)
  • Access reports of the quality checks for all uploaded vocabularies
  • Quality reports can also be sent to you by email, if you wish
PoolParty team asks for feedback and suggestions on the service!

PoolParty PowerTagging – bringing semantics to enterprises

PoolParty PowerTagging (PPP) is on its way: By extending Confluence´s label management, new application scenarios which make use of content recommendation and semantic indexing will be supported soon. PPP will be published at this year´s Atlassian Summit and at SemTechBiz in San Francisco at the beginning of June.

The Problem: weak semantics

Tagging is still not a very popular task, especially in corporate environments. Many users don´t see the benefit of creating metadata to describe the actual content. A typical counter-argument to social tagging is that there are too many words for the same thing. “Even if I am tagging very hard my colleagues won´t find necessarily my pages  because they will use different words to search for the content. I don´t have enough time to insert ‘New York City’, ‘NYC’, ‘Big Apple’ etc. as labels”.

The result: Tagging facilities of enterprise software platforms like Confluence are rarely used and don´t help to index content at all. Search is mostly based on classical full-text indexing. Semantic search as seen more and more on the WWW has still not entered the enterprise realm.

The Solution: thesaurus based indexing

W3C´s Semantic Web technology stack provides means to define controlled vocabularies like thesauri which results into more and more tools and data which make use of standards like SKOS. Tagging based on thesauri means that concepts are attached to pages & documents rather than putting labels on them. Labels like ‘New York City’, ‘NYC’ and ‘Big Apple’ refer to the same concept, thus it should be sufficient if one of the various terms is used for labeling, all the other names of this certain concept should be attached automatically.

PoolParty PowerTagging is able to analyse each Confluence page and to insert concepts from a thesaurus and all of their names automatically. Users can curate all suggested tags or they can also index their spaces automically resulting in a semantic index which makes search more comfortable than ever before.

Usage: enhanced collaboration with enterprise knowledge models

There are two main application scenarios which can be realised on top of Confluence and its PowerTagging extension:

  • Semantic Search: Fully integrated with Confluence´s built-in Lucene based search facility, users no longer have to type in search phrases literally: Even if only ‘New York City’ is mentioned on a page on a word-by-word basis, it´s sufficient to search for ‘Big Apple’ or ‘NYC’ and results will be generated. This feature is especially interesting for domains in which a lot of technical terms or abbreviations are commonly used or for enterprises in multi-lingual environments.
  • Content recommendation: Identifying similar and semantically matching contents especially in larger Confluence instances is a crucial task: Imagine you´re working for a recruiting company and you would like to match a new open position with all people in your applicant database. Or: Imagine you´re working on technical documentation and you can provide your customers automatically with further readings. Or: Imagine you´re working on a slidedeck and you´ll see instantly if some of your colleagues have worked on similar issues recently.

Don´t re-invent the wheel again and again. Save time and money. PPP will help to fulfill these tasks when creating rich contents more efficiently than ever before. You can link similar contents within Confluence automatically and you can fetch further readings even from the WWW like from Wikipedia.

If you are interested in trying out PowerTagging, please drop us a note and we will be happy to support you!

Which kind of controlled vocabularies matter?

Looking at intermediate results of the Controlled Vocabularies Survey an interesting finding concerns the question which types of knowledge models are currently best fit for actual use in applications.

So far 143 people whose organization already make use of controlled vocabularies answered the question “Which kind of controlled vocabulary do you use or plan to use in your applications?”.
The results so far show that lightweight models like taxonomies and thesauri are somewhat preferred over ontologies:

Taxonomies are the favorite, as 73.6% of participants use or plan to use them, followed by thesauri (62%) and ontologies (61.2%), while simple glossaries lag considerably behind with a usage of 31.4%.

This survey will close in about a week, so please take this chance to make your opinions on this topic count! You can find the questions here, it will take 5-10 minutes to answer them.

All participants will gain access to a report with the results within the following month. The most interesting results will be made public on this blog.
