Sentence Induced Transformations in Conceptual Spaces
2008
The proposed work illustrates how "primitive concepts" can be automatically induced from a text corpus. The primitive concepts are identified by the orthonormal axis of a "conceptual" space induced by a methodology inspired to the latent semantic analysis approach. The methodology represents a natural language sentence by means of a set of rotations of an orthonormal basis in the "conceptual"space. The rotations, triggered by the sequence of words composing the sentence and realized by means of geometric algebra rotors, allow to highlight "conceptual" relations that can arise among the primitive concepts.
Combining textual and visual cues for content-based image retrieval on the World Wide Web
2002
A system is proposed that combines textual and visual statistics in a single index vector for content-based search of a WWW image database. Textual statistics are captured in vector form using latent semantic indexing (LSI) based on text in the containing HTML document. Visual statistics are captured in vector form using color and orientation histograms. By using an integrated approach, it becomes possible to take advantage of possible statistical couplings between the content of the document (latent semantic content) and the contents of images (visual statistics). The combined approach allows improved performance in conducting content-based search. Search performance experiments are report…
Automatic Illustration of Short Texts via Web Images
2015
In this paper we propose a totally unsupervised and automatic illustration method, which aims to find onto the Web a set of images to illustrate the content of an input short text. The text is modelled as a semantic space and a set of relevant keywords is extracted. We compare and discuss different methods to create semantic representations by keyword extraction. Keywords are used to query Google Image Search engine for a list of relevant images. We also extract information from the Web pages that include the retrieved images, to create an Image Semantic Space, which is compared to the Text Semantic Space in order to rank the list of retrieved images. Tests showed that our method achieves v…
An architecture with a mobile phone interface for the interaction of a human with a humanoid robot expressing emotions and personality
2011
In this paper is illustrated the cognitive architecture of a humanoid robot based on the proposed paradigm of Latent Semantic Analysis (LSA). This paradigm is a step towards the simulation of an emotional behavior of a robot interacting with humans. The LSA approach allows the creation and the use of a data driven high-dimensional conceptual space. We developed an architecture based on three main areas: Sub-conceptual, Emotional and Behavioral. The first area analyzes perceptual data coming from the sensors. The second area builds the sub-symbolic representation of emotions in a conceptual space of emotional states. The last area triggers a latent semantic behavior which is related to the h…
Automatic concept maps generation in support of educational processes
2014
A VLE is a system where three main actors can be devised: the teacher in the role of instructional designer, the tutor, and the stu- dent. Instructional designers need easy interaction for specifying the course domain structure to the system, and for controlling how well the learning materials agree to such a structure. Tutors need tools for having a holistic perception of the evolution of single students and/or groups in the VLE during the learning process. Finally, students need self regulation in terms of controlling their learning rate, reflect on their learning strategies, and comparing with other people in the class. In this work we claim that sharing an implicit representation of the…

Reverse Modelling Process to support of a Flemish Wooden Altarpiece Physical Restoration
2021
This study focuses on digital Computer Aided Restoration procedures to guide the complex physical restoration of an artwork, innovating and implementing traditional survey methods. As a case study some results are presented of a complex and articulated conservative restoration project on a sculpted and painted wing altar, preserved in the Regional Gallery of Sicily in Palazzo Abatellis, Palermo. The application of non-invasive and high information density 3D survey methodologies allowed to record and integrate into a unique digital platform (designed within the UnReal Engine) a wide quantity of heterogeneous data which document the work's state (diagnostic analyses, graphical annotation, hi…
Il Web Semantico e gli argenti di Pietro di Spagna nell'Abbazia di San Martino delle Scale
2011
Il saggio prende in esame le possibilità offerte dal web semantico alla comunicazione ed alla valorizzazione dell'opera d'arte e delle collezioni. Viene preso in esame a questo proposito come case study il corpus delle opere di Pietro di Spagna custodite presso l'Abbazia di San Martino delle Scale.
“In quelle montagne lì parlano dialetto”. Deissi e funzioni deittiche nei discorsi sulla differenza linguistica: i dati dell’atlante linguistico dell…
2020
Tema del contributo, che si articola in tre sezioni, è la deissi nel corpus dell’Atlante Linguistico della Sicilia (ALS). nella prima sezione, dopo un breve resoconto sui precedenti studi ALS sulla deissi, viene descritta la rete dei centri d’inchiesta (“rete pilota”) e vengono illustrate domande-input del questionario e composizione del corpus dati. La seconda sezione è dedicata all’illustrazione degli strumenti teorici mutuati dalla linguistica cognitiva e, in particolare, dalla semantica della concettualizzazione, per definire sia il quadro teorico della deissi nei discorsi metalinguistici, sia l’apparato metodologico utile all’analisi e all’interpretazione. I dati costituiscono il focus…
Dilalogo con le ragazze cinesi, con Milo De Angelis
2017
L'articolo tratta, in forma di conversazione con il grande poeta, i temi più decisi della poesia e del linguaggio poetico di Milo De Angelis, tra i quali: vaghezza semantica; ossimoro; arte e società; ecc. Una parte è dedicata a Pasolini e Luzi e ci si sofferma sul rapporto tra espressione linguistica, indefinito e infinito in Giacomo Leopardi. Il testo rientra in un progetto di studio sulla poesia di Milo De Angelis che si prefigge anche la diffusione in Cina dell'opera di uno dei più importanti poeti viventi.
