A Methodology for Graphical Modeling of Business Rules
2011
This work proposes a novel methodology based on the Business Process Modeling Notation (BPMN) standard capable of graphically modeling business rules. A set of new representation patterns allows business analysts to map processes described through BPMN into conditions and actions of business rules. Our approach exploits Domain Specific Language techniques in order to make the methodology independent from the programming language supported by the specific rule engine. Moreover, this work proposes a web graphical editor, instantiated on a specific sample scenario, where the selected rule engine is Drools, one of the most used open source products. The developed editor allows business analysts…
An Approach to Enhance Chatbot Semantic Power and Maintainability: Experiences within the FRASI Project
2012
The paper illustrates the implementation and semantic enhancement of a domain-oriented Question-Answering system based on a pattern-matching chat bot technology, developed within an industrial project, named FRASI. The main difficulty in building a KB for a chat bot is to handwrite all possible question-answer pairs that constitute the KB. The proposed approach simplifies the chat bot realization thanks to two solutions. The first one uses an ontology, which is exploited in a twofold manner: to construct dynamic answers as a result of an inference process about the domain, and to automatically populate, off-line, the chat bot KB with sentences that can be derived from the ontology, describi…

Representation
2020
Representation is a primitive notion of many philosophical theories and of cognitive science. It is assumed as an intuitively understandable label assigned to the functions by which a biological or an artificial agent takes part in the world in an epistemological or a behavioral manner. It is employed to define the conditions for the semantic individuation of the states of the agent. The notion of representation was introduced systematically in the Scholastics’ view of cognition. In modern philosophy, the term is often used as a verb. Representation becomes the function of a class of mental states. In contemporary philosophy, the debate over the semantic individuation of states is intertwin…
The impact of deep dysgraphia on graphemic output buffer disorders
2004
This article describes an investigation into the residual writing skills of a severely dysgraphic patient (DA). We found that they were powerfully influenced by a number of lexical variables (lexicality, frequency, imageability, length and geminates). His error pattern was characterized by semantic, lexical, substitution, deletion errors and fragment responses that preserved the first letter. Thus, DA's written spelling was characterized by both deep dysgraphic and graphemic output buffer effects. It is proposed that this pattern of performance represents a new "putative functional syndrome."
Interazione tra diversi codici attenzionali: spazio e semantica
2010
The asymmetric distribution of human spatial attention has been repeatedly documented in both patients and healthy controls. Biases in the distribution of attention and/or in the mental representation of space may also affect some aspects of language processing. The present talk will be focused whether biases in attention and/or mental representation of space affect semantic representations. In particular, we investigated whether semantic judgments could be modulated by the location in space where the semantic information was presented and the role of the left and right parietal cortices in this task. Findings suggest the existence of an attentional and/or mental representational bias in se…
Quasi conjunction and p-entailment in nonmonotonic reasoning
2010
We study, in the setting of coherence, the extension of a probability assessment defined on n conditional events to their quasi conjunction. We consider, in particular, two special cases of logical dependencies; moreover, we examine the relationship between the notion of p-entailment of Adams and the inclusion relation of Goodman and Nguyen. We also study the probabilistic semantics of the QAND rule of Dubois and Prade; then, we give a theoretical result on p-entailment.
Extending the semiotics of embodied interaction to blended spaces.
2015
In this paper, we develop a new way of understanding interactions in blended spaces. We do this by developing ideas about embodied semiotics and then apply these ideas to the analysis of interaction in mixed-reality blended spaces (where the physical world and digital world are blended deliberately to provide new forms of interaction). We discuss how blended spaces provide a new medium within which people have experiences. The semiotic analysis reveals how blended spaces are constructed across the physical and the digital, highlighting the ontology, topology, volatility, and agency present within them. It shows how people move between the physical and digital spaces through the objects and …
An Ontology Architecture for Standards Integration and Conformance in Manufacturing
2007
Standards reflect consensus on the semantics of terms. When used to communicate, whether between people or software systems, standards ensure the communication is correct. Different standards have different semantics for the same terms and express common concepts using different terms and in different ways. Communication between software systems based on different standards is sometimes difficult to achieve. Standards integration concerns the explicit representation of the overlapping sets of concepts in standards and the differences in their semantics to ensure that these standards are used consistently together. This in turn enables software that is based on integrated standards to intero…
