Issue 533: How to disambiguate polysemous concepts used as ontological classes

Starting Date: 
Working Group: 

In the 49th CIDOC CRM and 42nd FRBR CRM sig meeting (virtual), upon resolving issue 368, the sig assigned AF to redraft the use case of unpacking the polysemous concept "inscripition" into semantically distinct classes, to form part of the Modelling Principles document (see issue 351).

Dear All,

Please find enclosed my HW for issue 533 (disambiguation of polysemous concepts used as ontological classes).

This document is also available in the related folder of the "Issues; Working Documents” shared drive (

I have reshaped the reasoning about “inscription” and its polysemic value as discussed during last SIG under issue 368.

The content can be freely condensed, integrated or adapted to be used as contribution to the Modelling Principles documentation (—> issue 351).

Dear All,

See Achille's and my homework for Issue 533, to be added to the modelling principles as real life example from CRM SIG discussions.

Current Proposal: 

In the 55th CIDOC CRM & 48th FRBR/LRMoo SIG Meeting, MD presented HW undertaken together with AF & FM, on polysemous concept disambiguation –through the definition of distinct ontological classes. The example is taken from epigraphy and involves the polysemous term “inscription”.

Proposal to incorporate current HW in the Principles for Modelling Ontologies (the collated version by EC) and to add some graphics to it (HW to AF, MD, PF)

Decision: As proposed. Retrofit this to issue 351.
HW: EC, MD (for 351); 
HW: AF, MD, PF (for the graphics)

In the 55th joint meeting of the CIDOC CRM and SO/TC46/SC4/WG9; 48th FRBR/LRMoo SIG meeting, the SIG reviewed and approved HW by MD, AF & FM on polysemoys  concept disambiguation through the definition of distinct ontological classes, based on examples from epigraphy (inscription). The proposal stems from work undertaken in the context of developing CRMtex. The HW will be incorporated in the 'Principles for Modelling Ontologies' document (the version collated by EC). 

HW: graphics to illustrate what aspect of inscription each class and associated properties highlight assigned to AF, MD, PF.

Dear all,

Our homework for Issue 533 can be found in the following shared folder: (issue folder for the 56th meeting)

It provides graphics to illustrate the different inscription aspects, using the Antikythera mechanism as an example. 

Best regards,

In the 56th joint meeting of the CIDOC CRM and ISO/TC46/SC4/WG9 &49th FRBR/LRMoo SIG, the SIG approved the proposal by AF & PF to incorporate the graphical example of the inscription borne by the Antikythera Mechanism in the document describing how to tease apart the various aspects of the concept "Inscription" (i.e., physical, symbolic, linguistic). 

HW: MD to add a paragraph where the method applied to differentiate among the various meanings. Connect it to the Modelling Principles document (should be appended to it). 
HW: AF to contact Mark Mudge regarding the imaging techniques used in the deciphering of the inscription “ΑΕΤΟΣ ΕΠΙΤΕΛΛΕΙ ΕΣΠΕΡΙΟΣ”. 

The figures can be found here
