Disposizioni di agenti in spazi geometrici arbitrari: un approccio basato sulla computazione evolutiva

2015

In many different social contexts, communication allows a collective intelligence to emerge. However, a correct way of exchanging information usually requires determined topological conigurations of the agents involved in the process. Such a coniguration should take into account several parameters, e.g. agents positioning, their proximity, time eficiency of communication. Our aim is to present an algorithm, based on evolutionary programming, which optimizes agents placement on arbitrarily shaped areas. In order to show its ability to deal with arbitrary bi-dimensional topologies, this algorithm has been tested on a set of differently shaped areas that present concavities, convexities and ob…

L'obiezione di una Lady ed il computer che vince ai telequiz. Come la flessibilità ha consentito all'Intelligenza Artificiale di superare un limite i…

2014

Col passare degli anni abbiamo imparato a non stupirci più delle meraviglie che una macchina può realizzare. Oggi un computer è capace di riconoscere la scrittu- ra e la voce umana, di interpretarla, di riprodurla; può prendere decisioni impor- tanti e tempestive (come succede, ad esempio, in ambiti molto delicati come quel- lo medico) (Seising, Tabacchi, 2013, pp. 3-8), effettuare difficili previsioni ma an- che, e soprattutto, gestire dinamicamente la complessità derivante dal mondo esterno, riuscendo addirittura a riconoscere e correggere i propri errori. Per rende- re possibile tutto questo, l’uomo ha dovuto compiere nell’ultimo secolo un mira- bile sforzo intellettuale che lo ha portat…

Computational Intelligence and Citizen Communication in the Smart City

2016

Information and communication are at the core of the intelligent city of tomorrow, and the key components of a smart city cannot prescind from data exchanges and interconnectedness. Citizen communication is an integral part of the smart city’s development plans: freedom of information and involvement in collective decisions, e-democracy and decision-making feedback can be greatly enhanced in an intelligent city, and, among other smart city components, foster a new era of participation and wise decisions. In this contribution we describe the methodologies that can be implemented in order to correctly develop automatic recognition systems for citizen communication, paying special attention to…

Agents Displacement in Arbitrary Geometrical Spaces: An Evolutionary Computation based Approach

2015

In many different social contexts, communication allows a collective intelligence to emerge. However, a correct way of exchanging information usually requires determined topological configurations of the agents involved in the process. Such a configuration should take into account several parameters, e.g. agents positioning, their proximity and time efficiency of communication. Our aim is to present an algorithm, based on evolutionary programming, which optimizes agents placement on arbitrarily shaped areas. In order to show its ability to deal with arbitrary bi-dimensional topologies, this algorithm has been tested on a set of differently shaped areas that present concavities, convexities …

Early usage of Pokémon Go and its personality correlates

2017

Pokmon Go is a popular augmented reality mobile game. Players find imaginary creatures by wandering into the real world, which can then be collected and used in combat. In this paper an assessment of Pokmon Go early usage in the Italian community and of its correlates with the Big Five personality traits is given. The resulting profile of early PG player is one of a more Introverted, close person with high agreeability and conscientiousness. Extraversion and Stability are positively correlated with the collection part of the game, while Agreeableness is a negative predictor thereof. Openness is correlated to the level of proficiency. Display Omitted We assess Pokmon Go early usage and its c…

An automatic system for helping health consumers to understand medical texts

2015

Medical texts (reports, articles, etc.) are usually written by professionals (physicians, medical researchers, etc.) who use their own language and communication style. On the other hand, these texts are often read by health consumers (as in the case of medical reports) who do not have the same skills and vocabularies of the experts and can have difficulties in text comprehension. To help a health consumer in understanding a medical text, it would be desirable to have an automatic system that, given a text written with medical (technical) terms, translates them in simple or plain language and provides additional information with the same kind of language. We have designed such a system. It …

Towards the Improvement of Citizen Communication Through Computational Intelligence

2016

When dealing with problems that arise from collective sharing of resources in metropolitan areas (i.e., energy, pollution, traffic, health) most of the interaction between citizens and local governance is usually carried out through the use of natural languages. Digital technologies allows smart cities residents to communicate with a broad range of experts (e.g. bureaucrats, legislators, urbanists, etc.) that routinely use technical terminology seldom accessible to the layperson, or linguistic styles that are not immediately understandable. Although information technology should encourage citizen participation in governance at many levels, the different levels of knowledge possessed by the …

Towards a fuzzy-linguistic based social network sentiment-expression system

2015

Liking allows users of Social Networks, blogs and online magazines to express their support of posts and artifacts by a simple click. Such function is very popular but lacks semantic power, and some platforms have augmented it by allowing to choose a pictographic depiction corresponding to a feeling. What is gained in depth is lost in simplicity, and the wide acceptance liking has enjoyed did not carried to the sentiment version. We outline a sentiment-expression hybrid system based on textual analysis and linguistic fuzzy Markov chains overcoming the intrinsic limitations of liking without burdening the user with complex choices.

Technology and human sciences: A dialogue to be constructed or a common tread to be rediscovered?

2013

In this contribution we begin to discuss the thesis that an analysis of the similarities and differences of typical methodologies of human sciences, technology and hard sciences show some unforeseen but strong similarities between human sciences and technologies. In this context fuzzy sets ideas provide useful tools which help to render the analysis more quantitative but without loosing the connection with a purely descriptive analysis. These kinds of considerations would have been hardly conceivable in the setting of XIX Century conception of science. It is the development of Information sciences that has allowed these problems to emerge. In this paper we shall then briefly outline the gen…

A fuzzy methodology to alleviate information overload in elearning

2013

Some aspects of eLearning experience can be en- hanced in a very natural way by using the basic tools offered by fuzzy logic. As a matter of exam- ple, consider the uncontrolled growth of informa- tion produced in a collaborative-oriented context, in which each participant (e.g. students, teachers) is able to insert and share new contents (e.g. com- ments, texts) concerning a university course. All the incrementally added pieces of information can be evaluated in several ways: by the intervention of a “dictator” (e.g. the teacher), using a rating form, or even according to the frequency of access. As contents rapidly become unusable for the effects of information overload, basic tools of fu…

Can you feel it will you tell me. Encouraging sentiment expression on the web

2015

In a recent trend in web communication, news outlets and blog platforms allow readers to express opinions about what they have read by choosing an associated feeling, or sentiment ex- pression. This emerging trend, fitting between liking and full text comments, has not still found the popularity it should. The thesis of this paper is that this is also due to the way the sen- timent choice is presented to the user. In order to test this hy- pothesis we have devised a pilot experiment; results confirm that a simpler way of choice increases sentiment expression and yields result that are more aligned with ground truth.

Creazione di collegamenti a scambio di informazione nei social network. Una simulazione agent-based con metodologia soft computing.

2015

La robustezza di una rete sociale dipende da caratteristiche intrinseche della  sua  topologia,  quali  ad  esempio  l’invarianza  di  scala,  la  presenza  di   nodi denominati hub (i nodi più popolari del network, Barabási e Albert 1999), una distribuzione di probabilità esponenziale, come quella illustrata in Figura 1, nel grado dei vertici P(x) =x^(-α)  con  fattore α  compreso  tra 2  e 3,  (come  quella  descritta  da  Albert  e  Barabási  2002);  ma  l’origine  di  queste  caratteristiche va ricercata come emergente dal comportamento dei singoli componenti della rete, e non necessariamente nel suo complesso (in tal senso è emblematico il caso del World Wide Web, come descritto in Alb…
