Open AccessAnalysis of news sentiments using natural language processing and deep learning
This paper investigates if and to what point it is possible to trade on news sentiment and if deep learning (DL), given the current hype on the topic, would be a good tool to do so. DL is built explicitly for ...

Facilitating Agent Development in Open Distributed Systems
One of the main reasons behind the success of the Web is that many “regular users” are able to create Web pages that, using hyperlinks, incrementally extend both the size and the complexity of the Web itself. ...

Crash failure detection in asynchronous agent communication languages
Agent Communication Languages (ACLs) have been developed to provide a way for agents to communicate with each other supporting cooperation in Multi-Agent Systems (MAS). In the past few years many ACLs have bee...

Performative Patterns for Designing Verifiable ACLs
When people hear two actors reciting a conversation in a poem, they become attuned to the kinds of sounds that they are producing, which may not be apparent in the printed text of the poem. This result depends...

An Actor Algebra for Specifying Distributed Systems: The Hurried Philosophers Case Study
In this paper, we introduce an actor language following a “process algebra” notation. The idea is to define a formalism based on a standard process algebraic approach which provides basic object-oriented featu...

An Algebra of Actors
We introduce an object-oriented language following a “process algebra” style. The idea is to define a formalism that enjoys a clean formal definition allowing the reuse of the rich algebraic theory typical of ...
