Reasoning with Multilevel Contexts in Semantic Metanetworks

2000

It is generally accepted that knowledge has a contextual component. Acquisition, representation, and exploitation of knowledge in context would have a major contribution in knowledge representation, knowledge acquisition, and explanation, as Brezillon and Abu-Hakima supposed in [Brezillon and Abu-Hakima, 1995]. Among the advantages of the use of contexts in knowledge representation and reasoning Akman and Surav [Akman and Surav, 1996] mentioned the following: economy of representation, more competent reasoning, allowance for inconsistent knowledge bases, resolving of lexical ambiguity and flexible entailment. Brezillon and Cases noticed however in [Brezillon and Cases, 1995] that knowledge-…

Icone gay: tra processi di normalizzazione e di resistenza. Ricostruire la semantica degli hashtag

2018

The mediatization of emotions emerges as an affordance of social media, the study of which involves paying attention to digital practices and the formation of the sense of public affection, of connected audiences expressing their participation through expressions of sentiment. This happens both for the great events and for the daily demonstrations of support or of its negation. Here we choose to analyze the tweets in which the fans express their opinions on the participation in the reality shows of their “icons”: Vladimir Luxuria and Cristiano Malgioglio. To reconstruct the hashtag semantics we use: the NodeXL software for network analysis and Iramuteq for the extraction of lexical worlds.

A Geometric Approach to Automatic Description of Iconic Scenes

2005

It is proposed a step towards the automatic description of scenes with a geometric approach. The scenes considered are composed by a set of elements that can be geometric forms or iconic representation of objects. Every icon is characterized by a set of attributes like shape, colour, position, orientation. Each scene is related to a set of sentences describing its content. The proposed approach builds a data driven vector semantic space where the scenes and the sentences are mapped. Sentences and scene with the same meaning are mapped in near vectors and distance criteria allow retrieving semantic relations.

Convergence of Web 2.0 and Semantic Web: A Semantic Tagging and Searching System for Creating and Searching Blogs

2007

The work presented in this paper aims to combine Latent Semantic Analysis methodology, common sense and traditional knowledge representation in order to improve the dialogue capabilities of a conversational agent. In our approach the agent brain is characterized by two areas: a "rational area", composed by a structured, rule-based knowledge base, and an "associative area", obtained through a data- driven semantic space. Concepts are mapped in this space and their mutual geometric distance is related to their conceptual similarity. The geometric distance between concepts implicitly defines a sub-symbolic relationship net, which can be seen as a new "sub- symbolic semantic layer" automaticall…

Joint Drafting of Legal Provisions in Multilingual Systems: an Analysis of the Swiss COVID-19 Regulations from a Legal Linguistic and Translational P…

2020

International audience; Legal language is known for its various technicalities and subtleties that often insulate legal translation from other specialized fields. In addition to the mere linguistic transfer of the text, along with the lexical, syntactical and pragmatic features specifically inherent in a Language for Legal Purpose (cf. Cao 2007), a comparison of two different legal systems becomes imperative in most cases (cf. Sandrini 1999). Even in light of the current pandemic that has forced governments to quickly lay down measures aimed at containing the spread of the virus, fundamental legal principles continue to apply.One might argue that a rapidly spreading virus can affect legisla…

Frame-Semantics meets Multilingual Legal Terminology. Theoretical Principles Based on a German-French Case Study

2021

International audience; Terminology aims primarily at elaborating standardized notions for the various complex concepts within specialized fields, intending to separate clearly defined technical terms from general lexical units that are used in every-day situations, with yet a wide range of vocabulary, that is specialized to some extent but cannot be delimited by terminological standards, emerging in between (ten Hacken 2010, 2015). For legal experts, for instance, the elaboration of precisely determined legal terms contributes to an overall specific understanding of legal concepts regardless of the possible ambiguities the same term may have in a general setting. At the same time, a variet…

Il volume raccoglie dei contributi che hanno come comune denominatore le categorie semantiche dello spazio e del tempo rilevate da termini che permettono di costruire l'oggetto di un sapere attraverso la descrizione degli spostamenti semantici o delle contaminazioni e interferenze fra i due concetti.

Predicting Word Maturity from Frequency and Semantic Diversity: A Computational Study

2016

Semantic word representation changes over different ages of childhood until it reaches its adult form. One method to formally model this change is the word maturity paradigm. This method uses a text sample for each age, including adult age, and transforms the samples into a semantic space by means of Latent Semantic Analysis. The representation of a word at every age is then compared with its adult representation via computational maturity indices. The present study used this paradigm to explore to the impact of word frequency and semantic diversity on maturation indices. To do this, word maturity indices were extracted from a Spanish incremental corpus and validated, using correlation scor…

Evaluative meaning

2012

Linguistic evaluation has become an important area of inquiry in recent years. In the traditions of, e.g., lexical semantics, phraseology, corpus linguistics, and interactional linguistics, a large inventory of linguistic means have been identified by which speakers can express evaluative meanings. However, the class of German sentential idioms, e.g., Das kannst du dir in die Haare schmieren (lit. ‘You can smear that into your hair’, fig. ‘That is useless’), has not gained much attention. This paper explores how the evaluative meaning of German sentential idioms is constructed syntactically, semantically, and pragmatically. In particular, it is investigated how the meaning of these idioms i…
