Dear all,

I'm a post-doctoral researcher at the Artificial Intelligence Research Group
of the University of Rome Tor Vergata. My Phd thesis was on " Alignment and
Mediation of Distributed Information Sources in the Semantic Web" and based
on the hypothesis that shareability and integration should be supported from
the early development stage of ontologies, when "linguistically motivated"
conceptual resources can better explain themselves both for machines (more
linguistic anchors --> easier automatic matching/mapping) and humans
(informal lexical descriptions help to restrict the range of interpretations
given by humans even beyond those imposed by the formal restrictions).

I'm also consultant for the Food and Agriculture Organization (FAO) of the
United Nations, and actively working on:
1) porting to Linked Open Data of their vocabularies and thesauri (AGROVOC,
BIOTECH) and data, moving to RDF from their legacy models. The last SKOS-XL
incarnation of AGROVOC is currently on the LOD Cloud
2) supporting development of Collaborative (Multilingual) Thesauri Editing

In my research and work, I've "felt" need for more elaborated onto-lexica
standards and inadequateness of current standards from many perspectives. In
particular, to give one which has not always been underlined:
>From an engineering point, we need ways to easily reuse the many different
existing lexical resource models and to be able to cover them under a
unifying umbrella.
Ontology Developers should get tools capable of easily importing information
from arbitrary lexical resources and be able to link their resources to
these lexical entries, from mere words, which may "lose contact" with the
resource they come from, to other identifiers which may need to preserve
their original nature, such as synsets for wordnet. While the idea of using
wordnet-synsets (just an example) as an interlingua may be fool, surely two
ontologies explicitly linked through these identifiers may rely on a less
ambiguous common (sill linguistic) ground for communicating.
To avoid confusion: this does not cover the realization of a new lexicon
model (which, following [1], is out of the scope of this WG) but of a proper
onto-linguistic interface covering issues such as:
1) proper wrapping (least possible information loss) of existing resources
2) linking conceptual resources (OWL, SKOS ones) to them
and the standardization of vocabularies for making these wraps/links
Some of my works [2, inside that, pointers to previous ones] are related to
the above aspects.

The work with FAO can possibly provide test scenarios, and I would be
tempted to provide the first release of a widely known resource such as
AGROVOC by remodeling it according to the very last model for onto-lexica
integration and, most of all, to support development for this language
through FAO and TorVergata tools (see vocbench [3] and Semantic Turkey [4])
In our experience, SKOS (and in particular, the SKOS-XL extension foreseeing
reified labels) has satisfied many of our requirements, though I still feel
unsatisfied about a few aspects which still seem to diminish the linguistic
relevance in knowledge modeling (no details here, time for discussion in the
future :-) ).
