Thesaurusmanagement Quickstart Introduction

What are controlled vocabularies? organized arrangement of words and phrases used to index content and/or to retrieve content through browsing or searching include preferred and variant terms have defined scope or describe a specific domain

Thesaurus = a controlled vocabulary arranged in a known order and structured so that the various relationships among terms are displayed clearly and identified by standardized relationship indicators. Important: ISO is a standard for building thesauri SKOS is a W3C recommendation designed for representation of controlled vocabularies and is built upon RDF and RDFS. It allows publication of such vocabularies as linked data. 1 (September 19th, 2014)

ISO Part 1: Thesauri for information retrieval - published in developing a thesaurus (mono- and multilingual) - replaced previous standards ISO 2788/ includes data model and XML schema Part 2: Interoperability with other vocabularies - published in recommendations for the establishment and maintenance of mappings between multiple thesauri, or between thesauri and other types of vocabularies Data Model

SKOS Simple Knowledge Organization System SKOS provides a standard way to represent knowledge organization systems using the Resource Description Framework (RDF). Encoding this information in RDF allows it to be passed between computer applications in an interoperable way. Using RDF also allows knowledge organization systems to be used in distributed, decentralised metadata applications. Decentralised metadata is becoming a typical scenario, where service providers want to add value to metadata harvested from multiple sources.

Multilingual vocabulary issues (examples) structural problems: conceptual systems differ in the various languages equivalence problems: lexicalisation of concepts differs in different languages eg. bone – fish bone (en); Knochen – Gräten (de) [1] ; [1] intra- and inter-language problems; terms differ in meaning (homographs) given term can have more than one meaning in a language eg. Turkey (country) and turkey (animal) [1] 20 th August, 2014http://

Federated Model LoCloud vocabulary based on federated model having independent vocabularies for various languages in the same domain (no one language is dominant) alignment of vocabularies via concept identifiers, end-user can search in all linked indexing vocabularies AIT experimental application based on TemaTres Vocabulary Tool

TemaTres... supports distributed management models ensures consistency and integrity of data and relationships between terms has features specially designed to provide data traceability and quality control in the context of a controlled vocabulary supports the analysis and categorisation of terms for search enables vocabularies to be represented in a wide range of metadata standards relevant to knowledge management

TemaTres functionalities No limits to number of terms, alternative labels, levels of hierarchy, etc allows import/export of data in text or SKOS format multilingualism SPARQL endpoint relationships between terms notes user management Reports Additionally: meta-terms: define facets, collections or arrays of terms, expose vocabularies with powerful web services, search terms suggestion (did you mean...?), display terms in multiple deep levels in the same screen, user management, duplicate and free terms control, multilingual terminology mapping etc.

Why TemaTres? Fast to use Making vocabularies available as Webservice in the enrichment process Many vocabularies (like UNESCO, Gemet, PICO) have already been established with this tool and are usable in the LoCloud infrastructure ( 175 vocabularies available) Additionally own vocabularies can be created Best starting point: Skos-file for import
