Free Webinar on Enterprise Semantics

PoolParty Team gave a webinar on November 28, 2012. We talked about scenarios and applications using semantics in enterprises. Some of the use cases we have discussed were:

  • Semi-automatic tagging of content (SharePoint, Confluence, …)
  • Semantic enterprise search (Mindbreeze, FAST, Exalead, …)
  • Linked Enterprise Vocabularies
  • Enterprise linked data integration (queries across Oracle databases and unstructured text)

WATCH the VIDEO.

We showed the latest developments of PoolParty platform and we gave insights how structured data from relational databases can be mashed with unstructured text when using linked data alignment. We also showcased how we mashed a large text corpus with statistical financial data on top of PoolParty and UltraWrap.

Survey on “Perception and Relevance of Controlled Vocabulary Quality Issues”

The University of Vienna (Research Group Multimedia Information Systems) and the Semantic Web Company are conducting a survey on “Perception and Relevance of Controlled Vocabulary Quality Issues”.

The survey is aimed at practitioners who are using or who are planning to use controlled vocabularies in their organisation. We’d be happy if you take the time to fill in the questionnaire here.

The goal of this study is to find out how developers and users of controlled vocabularies deal with quality aspects of these vocabularies. More specifically, we want to answer these questions:

  • What does vocabulary quality mean for taxonomists?
  • Given a number of possible quality issues, what is their relevance in practical settings?
  • What vocabulary usage scenarios are affected by the quality issues?

The questionnaire can be answered anonymously. Similar to our preceding
survey from last year (Do Controlled Vocabularies Matter?) we will publish the results as a scientific contribution so the community can gain a better knowledge on how to
create and use controlled vocabularies.

Education Services Australia announces new release of Schools Online Thesaurus

Education Services Australia has recently announced the release of Schools Online Thesaurus (ScOT) v6.7.
ScOT and agreed standards for digital resources, technical infrastructure, metadata and rights management support a national operating environment for the digital resources and infrastructure.
As part of this infrastructure, the National Digital Learning Resources Network contains over 12,000 digital resources that are free for use in all Australian schools. The resources are made available to teachers through State and Territory portals or Scootle and to pre-service teachers through eContent.
Version 6.7 has made possible by a recent addition to the ScOT project team. Ben Chadwick has undertaken a Vocabulary Support role since January 2012 and his work with web-services, data mining and thesaurus editing has contributed to the delivery of a substantial body of work.

Significant steps have been taken in the area of non-English labels, especially the addition of Chinese, Indonesian, Japanese and Korean term translations. Other preliminary work, including development of language and character encoding support, facilitates translations in Arabic, Māori and other languages. A sample concept can be found at http://vocabulary.curriculum.edu.au/scot/976

This represents a substantial opportunity for ScOT to support users who are learning or who have a background in languages other than English. Online environments can be designed or adapted to take advantage of standardised language encoding and character support.
A number of new features and improvements have been developed in the ScOT website:
  • User generated reports – lists new, modified and deprecated terms
  • Cataloguing tool – quickly identifies hierarchical relationships within a group of terms
  • Linked Data API for querying ScOT database: SPARQL Endpoint
  • Tips and code examples for developing search tools and managing term changes
  • Revised license and simplified registration process
  • Auto-complete feature for searching ScOT
  • Web Content Accessibility Guidelines (WCAG 2.0) – range of issues identified and fixed
The associated report can be accessed from the ScOT website releases page http://scot.curriculum.edu.au/releases.asp.
ScOT is based on PoolParty technologies.

ADMS implemented in PoolParty Thesaurus Manager (PPT) 3.1.0 Release

ADMS – the Asset Description Metadata Schema of the European Commission Joinup Initiative, is a metadata vocabulary to describe semantic interoperability assets.

The Asset Description Metadata Schema (ADMS) is a common way to describe semantic interoperability assets making it possible for everyone to search and discover them once shared through the forthcoming federation of asset repositories.

 

One of the main objectives of ADMS is e.g. to foster cross-boarder services in Europe by the efficient re-use of semantic assets in e-Government.

 

Description of ADMS
ADMS will allow public administrations, businesses, standardisation bodies and academia to:
  • keep their own system for documenting and storing semantic assets;
  • improve indexing and visibility of their own assets;
  • describe semantic assets in a common way so that they can be seamlessly cross-queried and discovered by the community through a single access point (Joinup);
  • retrieve, compare and potentially link semantic assets to one another in cross-border and cross-sector settings;
  • identify assets to be reused avoiding duplication and expensive design work.

Outreach of ADMS
ADMS is the first step towards a federation of european assets repositories. From mid 2012, Joinup will make available a large number of semantic interoperability assets, described using ADMS, through a federation of asset repositories of Member States, standardisation bodies and other relevant stakeholders. Through this federation, semantic interoperability assets will become retrievable and available via a single point of access.

Please consult the ADMS brochure for further information.

 

ADMS implemented in PoolParty Thesaurus Manager (PPT) 3.1.0 Release

 

The current release 3.1.0 of the PoolParty Thesaurus Manager (PPT) of the Semantic Web Company provides now full ADMS capability!

Figure: PoolParty GUI for metadata management of controlled vocabularies – ADMS tab.

 

Therefore PoolParty Thesaurus Manager (PPT) now allows the content architect to fill in the full description of a controlled vocabulary (a SKOS Thesaurus) – means the meta data of a controlled vocabulary – following now also ADMS standards – these ADMS relevant meta data is automatically published with a controlled vocabulary using the ADMS RDF schema and thereby can be used to publish a vocabulary in the repository of Joinup or another relevant repository of semantic assets to ensure re-use of the controlled vocabulary and thereby interoperability for services et al.
