ISO SC 4/WG 4 Lexicon-Ontology relationsPWI 24622

NicolettaCalzolari

Exploratory meeting

Berlin, October 2010


To explore the need of doing something within ISO about the relations between Lexicon and Ontology

Do we/ISO need to address another (lexical) layer?

  • How lexicons and ontologies are linked and information mapped from one to the other

  • The ontological layer in a/connected to a lexicon

    Possible issues/questions:

  • Is LMF enough to represent Ontological links?

  • How to connect work being done in ISO Lexical group and ISO Ontology groups?

  • Lexicon and Ontologies: separation? or lexicalised ontologies? or ontologised lexicons?

  • Lexicon, Ontologies and Domains

  • On a very different dimension: Ontology of lexical/semantic/conceptual categories? Standardised semantic categories, ontology labels?

  • Relation to multilinguality

  • ...

Complex picture!Is there anything we need to do for Interoperability?

Work within ISO:

  • LMF: abstract meta-model for lexical representation

  • Ontology Group or more Groups?

  • Language Resource Ontologies: ontology of data categories

  • Real life:

  • Lexicons (e.g. WordNets) that are called Ontologies

  • Lexicons linked to Ontologies: to be used in applications, in multilingual systems, domains, …

  • Work on “ontologising” Lexicons: to allow exploiting various relations, to make inferences, …

  • Semantic Lexicons, with many types of relations among semantic units: these are often of “conceptual/world-knowledge” nature. Do we want DCs for these?

  • ...

Sparse issues, from Hong Kong

  • Relations linking L & O: designates, denotes, …

  • Relation between Ling. Objects, Terms and Concepts of O classes

  • O classes are related to the LE in different languages. Represent somewhere a relation betwlexentry & O

  • Multilinguality associated to an O

  • Linguistic annotation of O labels

  • Template based Ontologies

  • Semantic relations complementary to O relations

  • IE relations: how to express these?

  • Pragmatic properties of lexical units

  • OntologyMetaProperties Where?

  • Define relations with TMX, XLIFF, LMF, …

  • Hierarchy in the O

  • Use OMetadata Vocabulary to express O

  • ...

Sparse issues, from Hong Kong

  • Many issues & different dimensions/viewpoints

  • Many initiatives are going on, BUT in partially different, individual, specific directions. Even if sometimes small differences. Should avoid that

  • There is work on which to base the analysis of current state-of-art. Start from real experiences and try to generalise may be a fruitful methodology

  • Analyse which are the basic issues/components/principles/relations of the L/O relation

    • E.g. Principle of economy of an O

    • While the L is larger: A lot of linguistic/lexical info

  • Multilinguality is another relevant issue

  • Analysis of LMF: has to be touched?

  • How to relate with O groups in ISO?

  • Worthwhile to do some work on this

  • But need someone willing to contribute, also to write the draft proposal

Berlin, October 2010


Some contributions

  • Laurent – help identifying a scope for a future project. Compile summarising slides

  • Thierry – with slides from Monnet & other ideas

  • Thorsten – willing to contribute

  • Antonio Pareja – willing to contribute

  • Harry –

    Then we discuss ….

Some contributions in HK

  • Key-Sun –Present my work about this issue

  • Thierry - A model for the relation between Ling. Objects, Terms and Concepts of Ontology classes. We build for this also on LexInfom (Paul et al) and OTR (Nathalie Aussenac-Gilles et al). The ISO relevant aspects are the DatCats

  • Piek–

  • Eric –Project about (helping) building ontologies from language. The focus is not on lexical ontology relations (on the application side) but this is something pertinent from a more linguistic point of view (for instance, about using thematic roles in relations)

  • Marc –A tool called VICOS which allows users to create informal ontologies anchored in (parts of) lexical entries. LMF interchange formats together: the issue of representing relations is also of interest there, even though these are not necessarily ontological ones

  • Samuel –Experience in the multilingual domain

  • Nasredine–Building semantic lexicons from ontologies and their applications in cross-language information retrieval and machine translation

  • Laurent –Ontolgy slides …

  • Kara –

    Then we discuss ….
