“…This remark is valid in general, independently from the type of formalization used see, to give only an example, the story trees of Mani and Pustejovsky (2004). A recent paper dealing in detail with the NKRL approach to the formalization of the connectivity phenomena, the syntax and semantics of the associations of elementary events, the binding operators and related topics is Zarri (2014a). An example of formalization of a scenario including several elementary events can be found in Zarri (2014b) 5 .…”

We describe in this paper a formalization of the notion of "role" that involves a clear separation between two very different sorts of roles. Semantic roles, like student or customer, are seen as (pre-defined) transitory properties that can be associated with (usually animate) entities. From a formal point of view, they can be represented as standard concepts to be placed into a specific branch of a particular ontology; they formalize the static and classificatory aspects of the notion of role. Functional roles must be used, instead, to model those pervasive and dynamic situations corresponding to events, activities, circumstances etc. that are characterized by spatio-temporal references; see, e.g., "John is now acting as a student". They denote the specific function with respect to the global meaning of an event/situation/activity… that is performed by the entities involved in this event/situation... and formalize the dynamic and relational aspects of the notion of role. A functional role of the subject/agent/actor/protagonist… type is used to associate "John" with the notion of student or customer (semantic roles) during a specific time interval. Formally, functional roles are expressed as primitive symbols like subject, object, source, beneficiary. Semantic and functional roles interact smoothly when they are used to deal with challenging knowledge representation problems like the so-called "counting problem", or when we need to set-up powerful inference rules whose atoms can directly denote complex situations. In this paper, the differentiation between semantic and functional roles will be illustrated from an NKRL point of view. NKRL (Narrative Knowledge Representation Language) is a high-level conceptual tool used for the computer-usable representation and management of the inner meaning of syntactically complex and semantically rich multimedia information. But, as we will see, the importance of this distinction goes well beyond its usefulness in a specific NKRL context. In particular, the use of functional roles is of paramount importance for the set-up of those evolved n-ary forms of knowledge representation that allow us to get rid from the limitations in expressiveness proper to the standard (binary) solutions.

“…In a semantic annotation context, the trend is to move from a simple "keyword" approach to a "metadata" approach. Metadata can be defined in general as machine-readable structured collections of lexical items to be used to express statements about the organization and content of some sets of digital or non-digital documents (ZARRI, 2014). Thus, to perform the semantic analysis of the keyword in an ambiguous search, from a word that has more than one meaning, inserted by users, an ontological knowledge base built on refined metadata is required to provide accurate search results (LEE et al, 2018).…”

Semantic portals, such as socio-technical artifacts, involve different actors that are aligned to offer communication and information search services more quickly and accurately. The objective of this study is to describe the network of actors involved in the construction of semantic portals and their interrelationships. The precepts of the Actor-Network Theory were used as a methodology to design a network of semantic portals from selected studies in the literature. The results indicated that the design of the network of semantic portals points to actions of human actors: portal administrators, portal developers and end users, but also of non-human actors, which are made up mainly of technologies. Each actor has his or her interest contemplated as the other actors fulfill their roles towards a common goal - information of high added value. It can be concluded that the study of the features of the portal actors' network can guide changes in current standards, focusing on the quality of research results and the informational needs of the user community.

“…In the last decade, the emerging technologies for media indexing and retrieval, mainly geared to multimedia contents, have addressed the markup of narrative texts, thus prompting a number of initiatives that leverage structured semantic representations. In particular, the pioneering Narrative Knowledge Representation Language (NKRL) project combines the use of markup for the encoding of the narrative content of text with the use of frames to represent the narrated story incidents (Zarri, 1997(Zarri, , 2014. As part of the more general trend of constructing resources for the automation of language processing, Elson introduced a template-based language for describing the content of narrative texts, with the goal of creating a corpus of annotated stories, called DramaBank (Elson, 2012).…”

The ontology of drama

In this paper, we describe the ontology of drama called Drammar. Pervasive in old and new media, and relevant from a multi-disciplinary perspective that ranges from literary criticism and semiotics to aesthetics and psychology, the manifestations of drama are ubiquitous in today's culture, overcoming the boundaries of genres and formats. Drawing from an extensive survey of the literature on drama, Drammar formalizes the elements of drama in a media-and task-independent way. Drammar is encoded in OWL2 to provide an interoperable formal model for representing and studying drama in a variety of systems. Issued by a research initiative carried out in an interdisciplinary way over a decade, Drammar abstracts from the media and languages by which drama is conveyed, providing a formal systematization of the core notions about drama that leverages the theories and models of agency in the tradition of Artificial Intelligence. In this paper, we illustrate the ontology, describing its design and motivations through examples and use cases.
