Standards for language processingPrimary resources

(text, dialogues)Structural mark-upBasic annotations

[TEI, MPEG7, TMX(XHTML…), etc.]

NLP structures(annotations)POS tagging

Chunks (cf. Named Entities)Deep Syntactic structures

Co-references etc.[Eagles/ISLE,

CES, MATE,…]

Knowledge structuresHierarchies of types

Relations between concepts(subjects/topics etc.)

Links to primary resources[Topic Maps, OIL, RDF]

Lexical structures(Language models)

TerminologiesTransfer lexica

Context

ISO TC37 - Terminology and other language resources SC3 - Computer applications in terminology

ISO 12200 - Martif Latest version of TEI Terminology chapter

ISO 12620 - Data categories ISO CD (DIS: under ballot) 16642 - TMF

(Terminological Markup Framework) SC4 - Language resources

TC37/SC4 details

Scope: Platform for designing and implementing linguistic resource formats and processes Multi-layer annotation of linguistic resources Exchange of information between NLP modules

General strategy Involve a wide community from academia and industry

Identification of experts in the various work items Involvment through national standardizing bodies

Agenda Current: identification of possible work items and working groups Constituancy meeting and technical workshop at LREC (May

2002)

Organization

Secretary: Prof. Key-Sun Choi, Korea

Chair: Laurent Romary, France

International Advisory Committee Permanent Chair: Prof. Antonio Zampolli, Italy

Terminology of Language Resources Basic terminology of the various sub-fields of

language resources and general methodology Project leader: Klaus-Dirk Schmitz Sources:

annotation and representation [data architecture] Methods and principles for the design of an annotation

scheme Structural nodes and information units, Data category

specification Linking and pointing mechanisms, Feature Structures,

Meta-Markup « Stand-off » and « in-line » views - equivalences,

combining levels. Administrative data categories
