The Joint Ontology WOrkshops (JOWO, https://www.iaoa.org/jowo/2019/) is a venue of workshops that, together, address a wide spectrum of topics related to ontology research, ranging from Cognitive Science to Knowledge Representation, Natural Language Processing, Artificial Intelligence, Logic, Philosophy, and Linguistics.


### SCOPE
CREOL aims at gathering together researchers from different communities (Applied Ontology, NLP, AI, Semantic Web) to investigate the relationship between the semantic representation of objects and events and their context, from an ontological and linguistic perspective.

Dealing with context is a key factor in the conceptualisation of human experience, and thus a major issue for understanding natural language. It is well known that some properties of objects and events may be activated according to their context of occurrence, and thus determine selective access to salient aspects.

Current ontologies and lexicons (e.g. DOLCE [1], Unified Verb Index [2])) offer limited (meaning) representations of events and objects that then may find different realisations in text. Additionally, the growing interest towards multimodal information systems requires devising approaches and resources aimed at representing context by considering different sources (e.g., textual description, image, video) as a whole.

Contextual access to objects and events needs to be investigated at its interface with language and visual scene, as well. Recently, several advanced approaches have been proposed to model meaning representations of lexical items in their context (e.g., Deep contextualised word representations [3]). Likewise, approaches and resources have been designed to represent and make explicit the relations intervening between objects in scenes depicting events (e.g., Visual Genome [4]). Moreover, established theories of meaning representation allow for the representation of context to varying extent (e.g., Abstract Meaning Representation [5], Discourse Representation Theory [6]).

The goal of this workshop is to promote and discuss the design of ontologies, linguistic resources, and computational methods that treat context as a primary focus of interest.
