Visualising knowledge from chat debates in argument diagrams

2010

This study investigates whether combining chat discussion and construction of an argument diagram stimulates students to formulate new ideas in practising argumentation. In this study, 16 secondary school students discussed vivisection and gender equality in pairs using both free and structured chat tools. In structured chat, the students selected and completed partial sentences provided by the computer. After the discussion, they jointly constructed either argument diagrams freely based on the previous discussions with an Internet tool or modified a diagram the computer had constructed automatically during the structured chat. The freely constructed diagrams contained more of the students'…

Comparing ranking-based collaborative filtering algorithms to a rating-based alternative in recommender systems context

2017

Suuri sisältövalikoima eri internet palveluissa, kuten verkkokaupoissa, voi aiheuttaa liian suurta informaatiomäärää, mikä heikentää asiakaskokemusta. Suosittelujärjestelmät ovat teknologioita, jotka tukevat asiakkaan päätöksentekoa tarjoamalla ennustettuja suosituksia. On yleistä, että asiakkaalle näytetään lista tuotteista, joista asiakas voisi pitää, esimerkiksi top-10 lista elokuvista. Perinteisesti nämä listat ovat tuotettu käyttäen perinteistä arvosanapohjaista menetelmää, missä tuntemattomille tuotteille ennustetaan arvosana ja järjestetty lista muodostetaan arvosanojen perusteella. Sijoitusperusteinen lähestyminen laskee käyttäjien väliset samankaltaisuudet ja ennustaa järjestetyn l…

An Agents and Artifacts Approach to Distributed Data Mining

2013

This paper proposes a novel Distributed Data Mining (DDM) approach based on the Agents and Artifacts paradigm, as implemented in CArtAgO [9], where artifacts encapsulate data mining tools, inherited from Weka, that agents can use while engaged in collaborative, distributed learning processes. Target hypothesis are currently constrained to decision trees built with J48, but the approach is flexible enough to allow different kinds of learning models. The twofold contribution of this work includes: i) JaCA-DDM: an extensible tool implemented in the agent oriented programming language Jason [2] and CArtAgO [10,9] to experiment DDM agent-based approaches on different, well known training sets. A…

A Sentiment Enhanced Deep Collaborative Filtering Recommender System

2021

Recommender systems use advanced analytic and learning techniques to select relevant information from massive data and inform users’ smart decision-making on their daily needs. Numerous works exploiting user’s sentiments on products to enhance recommendations have been introduced. However, there has been relatively less work exploring higher-order user-item features interactions for sentiment enhanced recommender system. In this paper, a novel Sentiment Enhanced Deep Collaborative Filtering Recommender System (SE-DCF) is developed. The architecture is based on a Neural Attention network component aggregated with the output predictions of a Convolution Neural Network (CNN) recommender. Speci…

Comparative International Communication Projects: Overcoming the Challenges

2007

Over the last 10-20 years, comparative research in the feld of communication has almost become fashionable. Many factors are responsible for this, for example: an increased awareness of globalisation as a communication-driven process; an awareness of increased transnational conglomerization of media organizations; and the increasing use of the Internet which facilitates easier access to information around the world. But the big question is how to organize collaborative international communication research efectively? Which models of cooperation are available to us, and what are their advantages and disadvantages? In this article, I analyze fve ways of doing collaborative researches and thei…

TEACHER TEAMS AND SCHOOLS BECOME LEADERS TO DISSEMINATE INNOVATIVE PRACTICE

2016

We will introduce a study about teachers taking part in networking for personal development and becoming teacher leaders. In 2011 a multilevel national joint collaboration network of schools with innovative experience was created to foster dissemination of new teaching and learning experiences among teachers. In order to organize learning for teachers, a lesson based collaborative continuous teacher professional learning model was implemented. The research shows that conducting and analyzing lessons has helped participants become more competent professionals and develop skills that are crucial for a good leader. Categories characterizing teacher leaders and lead schools were identified. Fac…

Co-produzione di valore nei servizi museali e performance multidimensionali: un approccio dinamico a supporto del management culturale

2021

Contesto della ricerca: nei piccoli centri urbani la co-produzione di servizi museali può essere una leva per la generazione di valore pubblico. Obiettivi del paper: lo scritto mira ad illustrare come un approccio multidimensionale di performance governance sia in grado di offrire una prospettiva sistemica per l’identificazione degli outcome gestionali, organizzativi e di comunità nonché di evidenziare leve per il miglioramento dei processi di generazione di valore nei musei e a beneficio della comunità. Metodologia: dapprima si è proceduto alla revisione della letteratura sul tema della co-produzione di servizi pubblici. Per analizzare le performance di tali contesti collaborativi si è cos…

Critical Assessment of European Agenda for the Collaborative Economy, on behalf of European Parliament. In-Depth Analysis for the IMCO Committee

2017

The research paper describes the main legal challenges for regulating the collaborative economy and evaluates the definition of, and elucidates how the existing body of EU law applies to collaborative economy business models. In the last part, the paper elaborates on how a regulatory framework for non- professional provision of services and prosumers should look like and makes a few concrete proposals for future policies. This paper was commissioned by the Policy Department A for Economic, Scientific and Quality of Life Policies upon request of the European Parliament ́s Committee on the Internal Market and Consumer Protection.
