  abstract = {Organizational models often rely on two assumptions: openness and heterogeneity. This is, for instance, 
the case with organizations consisting of individuals whose behaviour is unpredictable, whose internal 
structure is unknown, and who do not necessarily share common goals, desires, or intentions. This 
fact has motivated the adoption of social-based approaches to modelling interaction in organizational 
models. The idea of social semantics is to abstract away from the agent internals and provide a social 
meaning to agent message exchanges. In this chapter, we present and discuss two declarative, social 
models interaction in terms of commitments. The second one adopts a rule-oriented perspective, and 
models interaction in terms of logical formulae expressing expectations about agent interaction. We use 
a simple interaction protocol taken from the e-commerce domain to present the functioning and features 
of the commitment- and expectation-based approaches, and to discuss various forms of reasoning and 
verification that they accommodate, and how organizational modelling can benefit from them},

  abstract = {In Semantic Web technologies, searching for a service means to identify
components that can potentially satisfy the user
needs in terms of outputs and effects (discovery), and that, when invoked
by the customer, can fruitfully interact with her (contracting).
In this paper, we present an application framework that encompasses both the
discovery and the contracting steps, in a unified search process.
In particular, we accommodate service discovery by
ontology-based reasoning, and contracting by reasoning about policies published in a formal
language. To this purpose, we consider a formal approach grounded on Computational Logic,
and Abductive Logic Programming in particular. We propose a framework,
called SCIFF Reasoning Engine,
able to establish, by ontological and abductive reasoning,  if a semantic web service  and a requester can
fruitfully inter-operate, taking as input the behavioural interfaces
of both the participants, and producing as output a
sort of a contract.},

  abstract = {Abductive Logic Programming (ALP) and Constraint Logic Programming (CLP) share
the feature to constrain the set of possible solutions to a program via integrity or CLP constraints.
These two frameworks have been merged in works by various authors, which developed efficient abductive proof-procedures empowered with constraint satisfaction techniques.
However, while almost all CLP languages provide algorithms for finding an optimal solution with respect to some objective function (and not just {\em any} solution), the issue has received little attention in ALP.

In this paper we show how optimisation meta-predicates can be included in  abductive proof-pro\-ce\-dures, achieving in this way a significant improvement to research and practical applications of abductive reasoning.

In the paper, we give the declarative and operational semantics of an abductive proof-procedure that encloses constraint optimization meta-predicates, and we prove soundness in the three-valued completion semantics.
In the proof-procedure, the abductive logic program can invoke optimisation meta-predicates, which can invoke abductive predicates, in a recursive way.},

  title = {Exploiting Semantic Technology in Computational Logic-based Service Contracting},
  abstract = {Dynamic composition of web services requires an automated step of
  contracting, i.e., the computation of a possibly fruitful
  interaction between two (or more) services, based on their policies
  and goals. In previous work, the SCIFF abductive logic language
  was used to represent the services' policies, and the associated
  proof procedure to perform the contracting.

  In this paper, we build on that work in order to exploit the results
  of the Description Logics research area to represent domain specific
  knowledge, either by importing the knowledge encoded in an ontology
  into a SCIFF knowledge base, or by interfacing the SCIFF proof
  procedure to an existing ontological reasoner.},
