Towards Seamless Human-Robot Dialogue through a Robot Action Ontology
No full textThis research paper introduces a novel methodology enabling the Zora humanoid robot to effectively engage in dynamic interactions by responding to user queries and complementing its responses with appropriate gestures. Notably, these inquiries may extend beyond mere questions to encompass action commands articulated by the user, which the robot proficiently recognizes and executes. The integration of a Large Language Model enhances the system's capabilities, particularly in the domain of questionanswering. To bolster the recognition and execution of action commands, we have employed a robot action ontology established in previous research endeavors. This ontology defines relevant classes and individuals, forming the basis for a nuanced understanding of user-inputted action commands. Further refinement involves the generation of succinct three-word strings for each action, ensuring semantic alignment with the user's verbal instructions. Importantly, our system operates in two distinctive modes: STATELESS and STATEFUL. In STATEFUL mode, the robot possesses awareness of its present posture, allowing it to execute action commands only when they align with its current state. This adaptive feature enhances the overall effectiveness of the system, catering to the dynamic nature of human-robot interactions and promoting a seamless and contextually aware dialogue between the NAO humanoid robot and its users
Paesaggi della complessità. La trama delle cose e gli intrecci tra natura e cultura
No full textIl libro propone riflessioni sul tema della complessità in generale e sulla questione della complessità ambientale in particolare, a partire da un approccio dinamico e sistemico. Piuttosto che affrontarla in termini formali e generici, gli autori dei saggi riconducono la complessità alle questioni cruciali del paesaggio (inteso come concetto paradigmatico), della biodiversità e della sostenibilità ambientale. Le prospettive teoriche sondano i fondali comuni delle conoscenze. Le proposte concrete affrontano le questioni del degrado della Biosfera e dell’esaurimento di molte risorse energetiche e alimentari primarie. La teoria della complessità costituisce indubbiamente una delle più grandi trasformazioni che hanno investito il pensiero scientifico durante gli ultimi decenni del secolo scorso. Interdisciplinarietà e trasversalità sono fra gli aspetti più interessanti della complessità. Basta guardarsi intorno per scoprire che i sistemi complessi esistono dappertutto e a tutti i livelli della realtà. Essi intervengono in ogni campo della ricerca scientifica, così come nella vita quotidiana. La teoria della complessità rappresenta oggi il linguaggio più ricco e adatto per studiare e capire il funzionamento e i comportamenti di oggetti e fenomeni solo in apparenza molto disparati, quali alberi, nuvole, dune, battiti del cuore, stormi d’uccelli e branchi di pesci, ma anche fenomeni catastrofici come terremoti, epidemie, lingue che spariscono e tumori che si diffondono nel corpo. La complessità evidenzia la creatività della natura e dell’uomo, e permette di congiungere scienza e arte, offrendo una chiave di lettura comune che soverchi la contrapposizione tra cultura scientifica e cultura umanistica. Il presente volume — in cui convergono dialogando fisica, chimica, ecologia, epistemologia, filosofia, storia, geografia, arti, teoria dell’informazione, biologia — si colloca già al di là di questa inutile e dannosa separazione, e si offre come possibile luogo di un confronto ormai necessario

Patico venir al mondo: linguaggio e arte alla prova del dolore tra Colli e Masullo
Full text linkObiettivo del presente saggio è far dialogare le proposte filosofiche di due autori che, per quanto innegabilmente diversi per formazione e interessi specifici, hanno affrontato in modo consonante il problema del dolore. Si tratta di Giorgio Colli (1917-1979) e di Aldo Masullo (1923-2020). Entrambi hanno posto al centro della loro speculazione il vissuto emozionale, accentuando la coloritura patica del logos. Quest’ultimo, in quanto elemento vitale, non viene da loro pensato come neutro o autonomo, ma incarnato e affettivamente collocato. Da una simile impostazione filosofica deriva, quindi, necessariamente l’attenzione al problema del dolore, inteso in entrambi i casi come fenomeno che delimita l’esperienza vissuta, ossia che mostra un altro rispetto alla coscienza individuata, rispetto al nostro dire “io”
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
