1 Harmonisation of terminological resources future perspectives CLARA Terminology course Gisle Andersen, 17. September

2 Utfordringer og målsettinger Challenges å utvikle nye norske termar som får brei aksept i dei respektive fagmiljøa, og å gjere eksisterande og nye termar tilgjengelige på ein slik måte at dei også blir tekne i bruk i alle aktuelle samanhengar Elektroniske termbankar er suverene som medium for å utvikla, lagra og spreia terminologi. (Mål og meining, s. 104) Dei terminologiske metodane varierte mykje, ofte gjekk arbeidet føre seg utan dokumenterte retningslinjer, og terminologien vart ofte ikkje gjord tilgjengeleg eksternt. Dei mange ulike dataformata som var i bruk, hemma effektiv søking og nettbasert presentasjon Fragmentation: Many different terminology resources, different methods, technical solutions and availability Need for coordination at national level, a common interface national terminological infrastructure: a term portal 11. mai 2010 Gisle Andersen, gisle.andersen@nhh.no 2

3 Harmonisation future perspectives Integration/merging of terminological resources Harmonisation methods: autonomous bases with common interface/search system vs. integrate into one termbase hybrid system Harmonisation levels terms concepts classification/subjects (granularity) subdomains/domains standards technology methods (e.g. for handling multiple entries) workflow, best practise A topical issue; Research needed Fornavn Etternavn, navn@nhh.no 3

5 Aims of CLARA 4A For professional and technical language resources, the harmonisation of language resources across Europe poses problems at both conceptual and technological levels. Although there are a large number of terminological resources in Europe, those resources are fragmented, located in different institutions and in different formats. We propose to develop language-independent methods and tools for constructing and consolidating multilingual termbases and ontologies, for corpus-based term extraction and for ontologybased domain recognition of text. Moreover, we propose to investigate the degree of compatibility of different term bases at the top level of domain classification, at the mid-level of sub-domain, and at the lowest conceptual level, i.e. the concept itself and its hierarchical relations to neighbouring concepts within the sub-domain. The project aims to develop new, innovative approaches to cross-termbase integration Fornavn Etternavn, navn@nhh.no 5

12 Terminological entries The knowledge base terminologies are intended to cover a broad range of central concepts within each domain and to be based on consensus between subject specialists in the relevant domains. Entries in the termbases contain substantive multi-layered conceptual information and metadata descriptions that enable users to access data via any conceptual representation, including terms, definitions, concept relations, other semiotic representations, usage examples and potentially also a domainspecific text corpus, dependent on availability. Individual entries will minimally have an officially recognised term in Norwegian bokmål and/or nynorsk and a definition, but typically the entry will also contain at least the corresponding English term. 11. mai 2010 Gisle Andersen, gisle.andersen@nhh.no 12

13 Functionality The conceptual data will be both browseable and searchable. Domain and subdomain relations will be accessible to the user, who may search unrestrictedly, in multiple domains, or in a specific domain (including or excluding its subdomains) by ticking off relevant boxes. Linking and navigation between concepts is done via metadata representations of the semantic relations synonymy, superordinate, subordinate and coordinate concepts. The system will offer graphic representations of ontological structure and concept hierarchies, and visual semantic networks will be generated on-the-fly. Termbase entries will also include possible non-preferred synonymous terms (with a user warning). 11. mai 2010 Gisle Andersen, gisle.andersen@nhh.no 13
