Software tools Data/ontology resources Events and contacts People


LD activities in government (UEP-driven)

Czech instance of CKAN - http://cz.ckan.net/– currently with 145 catalogued resources – tagging by IPSV codes

A complex of methodologies covering different phases of the LGD lifecycle is under development

An experiment in ‘overspecialized contracts detection’ planned for Autumn 2011– use case: renewable energy– 200+ students will annotate data and

collaboratively build product parameter ontologies Agreement with Czech Statistical Office

– codes triplification and linking

LD activities in government (CU-driven)

http://OpenData.cz – Initiative for transparent data infrastructure– primarily contacts with municipalities

Public Contracts ontology– (largely) compliant with TED schema

Triplified public contracts data – from ISVZUS system and registries

CU is running a LD infrastructure– currently Sesame-based– own library of scrapers and cleaners

Ontological engineering and ontology matching

PatOMat: OWL ontology ‘modelling style’ transformation services– based on transformation patterns– includes pattern editor and XDTools Java version

Taxonomy debugging based on naming patterns

To be integrated with ORE

Expertise in schema matching - OAEI Initial research on ‘unfolding’ LD schema elements

to more complex semantic patterns

Data mining

Sewebar – system for post-processing the results of descriptive data mining– Deals with source data, mining settings, output

hypotheses (all in complience with the PMML standard), and background knowledge

– Currently restricted to the GUHA data mining method

– Extension to concept learning in DL possibly in LOD2

Experience with organization of data mining challenges at ECML/PKDD– Linked Data Mining Challenge

envisaged in LOD2, for LGD

Text and multimedia mining

SCM&THD: tool suite for hypernym discovery based on Wikipedia and Wordnet

Also heavier-weighted tools– Ex: information extraction tool for

irregularly structured websites, based on ontology-like data models

The currently starting FP7 IP LinkedTV will make use of LD resources in multimedia annotation
