Exploratory meeting

Berlin, October 2010


To explore the need of doing something within iso about the relations between lexicon and ontology

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

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

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 kong1

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

Some contributions

Some contributions

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

  • Thorsten – willing to contribute

  • Antonio Pareja – willing to contribute

  • Harry –

    Then we discuss ….

Some contributions in hk

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 ….
