Musical Relevance: a Computational Approach.
In Proceedings of the 34th International Conference of the Cognitive
Science Society, pages 1248-1253, Sapporo, Japan, 2012. Cognitive
Science Society.
Abstract:
This study
is a first attempt at formalizing the concept of Musi- cal Relevance from a
cognitive and computational perspective. We elaborate on Sperber and Wilson's
Relevance Theory, and extend it to account for musical cognition, involving
both lis- tening and understanding. Our claim is that the application of the
concept of Cognitive Relevance to music would permit us to partially explain
hearers' behavior and composers' choices. A computational model of Musical
Relevance could also con- tribute to the formulation of a general
computational theory of musical cognition. In turn, formulating an algorithm
to com- pute Musical Relevance can shed light on the computational nature of
the broader cognitive principle of relevance. We pro- pose to unify Relevance
Theory with the Generative Theory of Tonal Music, in order to compute Musical
Relevance. We started implementing a system to test the proposed approach
over simple examples and report about the results in a prelim- inary
experimentation.

TULSI: an NLP System for Extracting Legal Modificatory Provisions.
Artificial Intelligence and Law, 12(4):1-34, 2012.
Abstract:
In this
work we present the TULSI system (so named after Turin University Legal
Semantic Interpreter), a system to produce automatic annotations of normative
documents through the extraction of modificatory provisions. TULSI relies on
a deep syntactic analysis and a shallow semantic interpreter that are
illustrated in detail. We report the results of an experimental evaluation of
the system and discuss them, also suggesting future directions for further
improvement.

Compiling Regular Expressions to Extract Legal Modifications.
In Burkhard Schafer, editor, Proceedings of the The 25th International
Conference on Legal Knowledge and Information Systems, Amsterdam,
Netherlands, 2012. IOS Press.
Abstract:
In this
paper we present a prototype for automatically identifying and classifying
types of modifications in Italian legal text. The prototype is part of the
Eunomos system, a legal knowledge management service that integrates and
makes available legislation from various sources, while finding definitions
and explanations of legal concepts in a given context. The design of the
prototype is grounded on the error analysis of a previous prototype. The
latter made use of dependency relations provided by the TUP parser, a
multi-purpose parser for Italian. Since those syntactic relations were
responsible of the majority of errors, we decided in the present tool to
ignore them, and to rewrite an ad-hoc shallow parsing, based on the
morphological analysis of the legal text (still provided by the TUP parser).
We obtained performances much greater than those of the initial prototype. In
particular, the level of precision of the classification in output is now
close to 100%.

A game theoretic approach to contracts in multiagent systems.
IEEE Transactions on Systems, Man, and Cybernetics, Part C,

Abstract:
In this
paper we address the problem of how autonomous agents acting on behalf of
their users reason about contracts inside virtual organizations. Contracts
are modelled as legal institutions: systems of legal rules which allow to
change the regulative and constitutive rules of an organization. The
methodology we use is to attribute to organizations mental attitudes, like
beliefs, desires and goals. Agents reason about the effect of contracts in
the interaction with other agents by means of game theoretic
techniques

An agent oriented ontology of social reality.
In Procs. of FOIS'04, pages 199-209, Amsterdam, 2004. IOS Press.
Abstract:
In this
paper we introduce an ontology based on the notion of agent to represent and
reason about social reality. We model social constructions as agents, for
example, groups, organizations, normative systems, and roles, and we
attribute mental attitudes to them. Roughly, we define obligations or
regulative norms as goals of the normative system, constitutive norms as
beliefs of the normative system, joint, shared, mutual and social beliefs,
desires and goal as beliefs, desires and goals of group, responsibilities of
an agent as goals of the role he plays, and the required expertise of an
agent as beliefs and actions of the role he plays. In this way, we achieve a
uniform framework for a large variety of concepts using a small vocabulary,
and, in particular, basing it on notions, like mental attitudes, which are
commonly used in agent theories. The proposed ontology is modelled using a
description logic.

In Procs. of ICEC'04. IEEE Press, 2004.
Abstract:
In this
paper we address the problem of defining roles in organizations like e-trade
ones. The methodology we use is to model roles according to the agent
metaphor: we attribute to roles mental attitudes, like beliefs, desires and
goals, we relate them to the agents required expertise and responsibilities,
and we model role behavior in game theoretic terms. Analogously, the
organization is modelled as an agent which acts as a normative system: it
imposes obligations to roles and to the agents playing the
roles

Fulfilling or violating obligations in normative multiagent systems.
In Procs. of IAT'04, Beijing, 2004.
Abstract:
A theory
of rational decision making in normative multiagent systems has to
distinguish among the many reasons why agents fulfill or violate obligations.
We propose a classification of such reasons for single cognitive agent
decision making in a single normative system, based on the increasing
complexity of this agent. In the first class we only consider the agents
motivations, in the second class we consider also its abilities, in the third
class we consider also its beliefs, and finally we consider also sensing
actions to observe the environment. We sketch how the reasons can be
formalized in a normative multiagent system with increasingly complex
cognitive agents.

Game specification in normative multiagent system: the trias politica.
In Procs. of IAT'04, pages 504-508, Beijing, 2004. IEEE Press.
Abstract:
In this
paper we formalize the specification of games in the trias politica using Rao
and Georgeff's specification language BDICTL*. In particular, we generalize
Rao and Georgeff's specification of single agent decision trees to multiagent
games, for which we introduce observations and recursive modelling, in this
setting we formalize obligations, and we characterize four kinds of agents,
called legislators, judges, policemen and citizens. Legislators are
characterized by their power to create and revise obligations, judges are
characterized by their power to count behavior of citizens as violations, and
policemen are characterized by their ability to sanction
behavior.

Groups as agents with mental attitudes.
In Procs. of AAMAS'04, pages 964-971, New York, 2004.
Abstract:
We discuss
a model of cooperation among autonomous agents, based on the attribution of
mental attitudes to groups: these attitudes represent the shared beliefs and
objectives and the wish to reduce the costs for the members. When agents take
a decision they have to recursively model what their partners are expected to
do under the assumption that they are cooperative, and they have to adopt the
goals and desires attributed to the group: otherwise, the other members
consider them uncooperative and thus liable.

Normative multiagent systems.

Abstract:
We are
interested in the design of policies for virtual communities of agents based
on the grid infrastructure. In a virtual community agents can play both the
role of resource consumers and the role of resource providers, and they
remain in control of their resources. We argue that this requirement imposes
a distinction between the authorization to access a resource given by the
virtual community and the permission to do so issued by the resource
providers. Our model is based on a logical multiagent framework that
distinguishes the three roles of resource consumption, provision, and of
authorization.

Decision-theoretic deliberation under bounded resources.
In Procs. of LOFT'04, Leipzig, 2004.
Abstract:
Agent
theory proposes to model the behavior of complex software systems in terms of
mental attitudes like belief, desires, goals, intentions and obligations,
ranging from, e.g., the PRS system [7] to the more recent BOID architecture
[3]. Decision-theoretic deliberation captures concepts and reasoning
mechanisms from agent theory in standard decision-theoretic terms. This is an
ambitious enterprise, as it has the objective to bridge the worlds of
decision theory and agent theory. Thus far, several partial results on the
decision-theoretic characterization have been obtained. The relation between
beliefs (as well as defaults) and probabilistic techniques has been studied
for some time, there are characterizations of desires and goals in
decision-theoretic terms [6], there are various interpretations of
obligations and norms, for example as social laws [8], and there are
preliminary results on intention [1]. See our comparison paper [4] for an
overview. The most problematic issue in decision-theoretic deliberation is
the characterization of intention. Roughly, whereas beliefs have been related
to probabilities, desires to utilities, and obligations to social laws,
intentions do not seem to have an obvious counterpart in classical game and
decision theory. However, most discussions on the popular BDI model have
focussed on the role of intention in deliberation [2]. Consequently, we
believe that intention is the benchmark example of decision-theoretic
deliberation.

Persuasion strategies in dialogue.
In Procs. of CMNA Workshop at ECAI'04, Valencia, 2004.
Abstract:
In this
abstract we consider dialogues that have a normative aspect. A dialogue is
regulated by norms, but can also establish new norms. Certain utterances
count as a particular dialogue move in some dialogue game, which creates
obligations and permissions for the participants. But norms do not operate in
isolation; we study their relation to mental attitudes of participants, in
particular beliefs (information), desires, goals or intentions.

An abstraction from power to coalition structures.
In Procs. of ECAI'04, Valencia, 2004.
Abstract:
The
concept of power plays an important role in the social sciences and
Castelfranchi [2, 3] emphasizes the importance of this concept for multiagent
systems. In [1] we build upon this work by distinguishing four viewpoints on
multiagent systems: a mind structure, a power structure, a dependence
structure and a coalition structure. These viewpoints are increasingly
abstract conceptualizations of systems as collections of autonomous cognitive
agents. In this paper we formally define one kind of power and coalition
structures, and an abstraction from this power to its coalition
structure.

Power and dependence in multiagent systems.
In Procs. of CEAS Workshop at ECAI'04, Valencia, 2004.
Abstract:
An
important aim in the field of Multiagent Systems is to study emergent social
structures, such as groups and collectives. The relevance of social
structures in Distributed Artificial Intelligence, Artificial Life, Sociology
necessitates a well motivated definition of their characteristics. The
research question of this paper is to formalize the results obtained by
Castelfranchi that try to bridge the gap between the BDI model and the
macro-level of Multiagent Systems. We presented in (AAMAS04)general social
viewpoints on Multiagent Systems and in (ECAI04) we have detailed a
derivation of coalition structures from power structures. In this paper we
continue the research, and we define power in terms of cognitive (or mind)
view, i.e., starting from the characteristics of the single agents as their
goals and skills. Properties of collectives, as mutual dependence or
cooperation, are also hierarchically defined by means of the definition of
power. It is shown that upper levels of this hierarchy need mental model of
the agents more and more complex.

our framework can be used to describe social and organizational structures as

reconsider the analysis of intentions proposed by Michael Bratman. Intentions
are defined as predominant desires that can be achieved; but identifying
which desire is the predominant one is a costly effort: the it information
produced during the planning phase is exploited when it meta-deliberating
about the reconsideration of the current intentions, giving them
stability.

Playing it safe: obligations for enforcing trust among agents.
In Procs. of RASTA 2002 workshop, 2002.
Abstract:
In some
strategic situations, which can be represented as 2x2 matrix games in the it
prisoner dilemma style, an agent prefers to enter the interaction only in
case he or the other player are subject to some obligations which incentives
them to stay it committed to a cooperative behavior. Obligations presuppose
the existence of a third agent who is in charge of sanctioning the
misbehaving agents and/or rewarding the agents who stick to their
commitments. In this paper, we propose a model of game situations where we
introduce an explicit it third party agent who has the role of enforcing
these obligations.

In D. Scott, editor, Artificial Intelligence: Methodology, Systems, and

Abstract:
We present
an algorithm for replanning in a reactive agent architecture which
incorporates decision-theoretic notions to drive the planning and
metadeliberation process. The deliberation component relies on a refinement
planner which produces plans with optimal expected utility. The replanning
algorithm we propose exploits the planner’s ability to provide an approximate
evaluation of partial plans: it starts from a fully refined plan and makes it
more partial until it finds a more partial plan which subsumes more promising
refinements; at that point, the planning process is restarted from the
current partial plan.

A game theoretic approach to norms.
Cognitive Science Quarterly, pages 492-512, 2002.
Abstract:
In recent
years, multi-agent systems have become one of the most promising approaches
for organizing software. However, the demand for capabilities of autonomous
decision making poses some requirements on agent architectures. It is
necessary, in fact, that the behavior of an agent be suitably constrained to
make it socially compatible with the community of agents. In this paper, we
propose a model for obligations and rules which is inspired to E. Goffman's
work in sociology, and which can be integrated in existing BDI (Belief,
Desire, Intention) agent architectures. We show that it Decision Theory and
it Anticipatory Coordination can be the basic building blocks for an agent
model where obligations are associated with sanctions (and with another
agent, the it normative agent, who takes care of making the obligation
respected). Anticipatory Coordination is required to foresee the normative
agent reactions, while Decision Theory enables an agent to choose in a
rational way the most promising line of action.

A plan
based agent architecture for interpreting natural language dialogue.
International Journal of Human-Computer Studies, (52):583-636,
2000.
Abstract:
This paper
describes a plan-based agent architecture for modeling NL cooperative
dialogue; in particular, the paper focuses on the interpretation dialogue and
explanation of its coherence by means of the recognition of the speakers'
underlying intentions. The approach we propose makes it possible to analyze
and explain in a uniform way several apparently unrelated linguistic
phenomena, which have been often studied separately and treated via ad-hoc
methods in the models of dialogue presented in the literature. Our model of
linguistic interaction is based on the idea that dialogue can be seen as any
other interaction among agents: therefore, domain-level and linguistic
actions are treated in a similar way. Our agent architecture is based on a
two-level representation of the knowledge about acting: at the metalevel, the
Agent Modeling plans describe the recipes for plan formation and execution
(they are a declarative representation of a reactive planner); at the object
level, the domain and communicative actions are defined. The Agent Modeling
plans are used to identify the goals underlying the actions performed by an
observed agent; the recognized plans constitute the dialogue context, where
the intentions of all participants are stored in a structured way, in order
to be used in the interpretation of the subsequent dialogue
turns.

computed by considering also the consequences of an agent's choice in terms

members of a group consider whether to adopt the goals of their partners: an
agent should adopt these goals only when the adoption results in an increase
of the group's benefit.

a model where dialog obligations arise from the interplay of social goals and

reaction of the requester and the cost of the actions needed to satisfy the
goals.

natural language researchers are currently turning their attention to
treebank development and trying to achieve accuracy and corpus data coverage
in their representation formats. This paper presents a data-driven annotation
schema developed for an Italian treebank ensuring data coverage and
consistency between annotation of linguistic phenomena. The schema is a
dependency-based format centered upon the notion of predicate-argument
structure augmented with traces to represent discontinuous constituents. The
treebank development involves an annotation process performed by a human
annotator helped by an interactive parsing tool that builds incrementally
syntactic representation of the sentence. To increase the syntactic knowledge
of this parser, a specific data-driven strategy has been applied. We describe
the cyclical development of the annotation schema highlighting the richness
and flexibility of the format, and we present some representational
issues.

The role of social goals in planning polite speech acts.
In Workshop on Attitude, Personality and Emotions in User-Adapted
Interaction at UM'99 Conference, pages 41-55, Banff, 1999.
Abstract:
In this
paper, we propose a logical description of the mechanisms which cause a
speech act to be impolite, and of how the indirect expressions may prevent
speakers from offending their partners. We specifically focus on conventional
indirect speech acts, providing a formal framework to recognize the beliefs
underlying them and the way how the possible offenses produced by
communicative actions may be blocked by using politeness
techniques.

Plan-based event representations for the analysis of tense and aspect.
In Proc. of 6th Congress of AI*IA, Submitted to conference review,
1999.
Abstract:
In this
paper, a representation formalism based on actions and hierarchical plans is
proposed to model the aspectual and temporal composition of sentences. Action
verbs are interpreted as instances of action schemata that include a plan
body; the other linguistic elements, like tense and adverbs, are evaluated by
means of rules that add constraints to event representations.

Beating a donkey: a mental model approach to complex anaphorical phenomena.
In Proc. of European Congress of Cognitive Science of ECCS'99,

Abstract:
In this
paper, we want to show that it mental models provide the adequate level for
explaining complex anaphoric phenomena, like donkey sentences. The key idea
is that anaphors can be more easily resolved by referring to an extensional
representation of the meaning of sentences, like the one provided by mental
models.

Abstract:
In this
paper, we suggest that AI techniques, especially the ones developed in the
field of agent modeling and intelligent interfaces, can be exploited both to
build systems for narrative understanding and to allow agents to describe
their own behavior in a narrative style. In particular, we will show how it
is possible to exploit a model of dialog interpretation for building a system
that understands stories and produces a representation of the characters'
plans and intentions.

Conversational cooperation: the leading role of intentions.
In Amstelogue'99 Workshop on Dialogue, Amsterdam, 1999.
Abstract:
We will
consider the role played by the notion of agent intentions in dialog and,
particularly, in explaining conversational cooperation. The decision to
cooperate towards the success of the communication accounts for grounding,
requests of repair, repairs to misunderstandings, and other related
phenomena. In the model, intentions arise from goals on the basis of two
factors: the relevance of a goal, and the cost of the actions needed to
achieve it. The adoption of the intention of cooperating at the
conversational level is motivated by the fact that the refusal to do low-cost
actions, in case they are supported by low-relevance goals, is usually
interpreted as an offense to the requester of the action.

An
agent model for nl dialog interfaces.
In Lecture Notes in Artificial Intelligence n. 1480: Artificial
Intelligence: Methodology, Systems and Applications, pages 14-27.
Springer Verlag, Berlin, 1998.
Abstract:
Agent
theories take as their paradigm human intentional behavior; however, as far
as agent interaction is concerned, they have not yet satisfactorily taken
into account the requirements raised by studies on human Natural Language
communication, the most developed means of interaction. The fundamental
missing point is the role of intention recognition, which is the basis of
human dialog interactions. In this paper, we describe a declarative agent
architecture for modeling social agent behavior, with particular attention to
Natural Language dialog. The architecture can be used both to recognize a
speaker's intentions and generate intention-driven behavior in agent
interactions; therefore, it is suited to interface agents for HCI, which
require a friendly interaction with users.

A
plan-based model of misunderstandings in cooperative dialogue.
International Journal of Human-Computer Studies, 48:649-679,
1998.
Abstract:
We
describe a plan-based agent architecture that models misunderstandings in
cooperative NL agent communication; it exploits a notion of coherence in
dialogue based on the idea that the explicit and implicit goals which can be
identified by interpreting a conversational turn can be related with the
previous explicit / implicit goals of the interactants. Misunderstandings are
hypothesized when the coherence of the interaction is lost (i.e. an unrelated
utterance comes). The processes of analysis (and treatment) of a
misunderstanding are modeled as rational behaviors caused by the acquisition
of a supplementary goal, when an incoherent turn comes: the agent detecting
the incoherence commits to restore the intersubjectivity in the dialogue; so,
he restructures his own contextual interpretation, or he induces the partner
to restructure his (according to who seems to have made the mistake). This
commitment leads him to produce a repair turn, which initiates a subdialogue
aimed at restoring the common interpretation ground. Since we model speech
acts uniformly with respect to the other actions (the domain level actions),
our model is general and covers misunderstandings occurring at the linguistic
level as well as at the underlying domain activities of the
interactants.

Automatic refinement of linguistic rules for tagging.
In Proc. 1rst International Conference on Language Resources and
Evaluation LREC'98, pages 923-930, Granada, 1998.
Abstract:
This paper
describes an approach to POS tagging based on the automatic refinement of
manually written linguistic tagging rules. The refinement was carried out by
means of a learning algorithm based on decision trees. The tagging rules work
on ambiguity classes: each input word undergoes a morphological analysis and
a set of possible tags is returned. The set of tags determines the ambiguity
class: the suitable subset of tagging rules is applied and a single tag is
returned. This method can be applied both with the original set of manual
rules and with the set of refined rules. The experiments have been performed
on the Italian language. The results show that the refined set reduces the
tagging error of about 17%. The noticeable feature of the approach is that
the original set of rules is not modified, so that they retain their
linguistic value, but new rules are added to handle problematic
cases.

Indirect speech acts and politeness: A computational approach.
In Proc. 17th Cognitive Science Conference, pages 316-321,
Pittsburgh, 1995.
Abstract:
This paper
describes a framework for the representation and interpretation of indirect
speech acts, relating them to the politeness phenomenon, with particular
attention to the case of requests. The speech acts are represented as actions
of a plan library and are activated on the basis of the presence of syntactic
and semantic information in the linguistic form of the input utterance. The
speech act analyzer receives in input the semantic representation of the
input sentence and uses the politeness indicators to climb up the
decomposition and generalization hierarchies of acts encoded in the library.
During this process, it eliminates the indicators and collects the negated
presuppositions (represented as effects of the indirect speech act) that
characterize the politeness forms. Some cyclic paths in the hierarchy allow
the system to cope with complex sentences including nested politeness
indicators. In the proper places of the hierarchy the semantic representation
of the input sentence is converted into a domain action in order to start-up,
when needed, the domain-level plan recognition process.

Evidence combination in expert systems.
International Journal of Man-Machine Studies, 22(3):307-326,

Abstract:
This paper
discusses some of the problems related to the representation of uncertain
knowledge and to the combination of evidence degrees in rule-based expert
systems. Some of the methods proposed in the literature are briefly analysed
with particular attention to the Subjective Bayesian Probability (used in
PROSPECTOR) and the Confirmation Theory adopted in MYCIN. The paper presents
an integrated approach based on Possibility Theory for evaluating the degree
of match between the set of conditions occurring in the antecedent of a
production rule and the input data, for combining the evidence degree of a
fact with the strength of implication of a rule and for combining evidence
degrees coming from different pieces of knowledge. The semantics of the
logical operators AND and OR in possibility theory and in our approach are
compared. Finally, the definitions of some quantifiers like AT LEAST n, AT
MOST n, EXACTLY n are introduced.

A text-to-speech translation system for italian.
International Journal of Man-Machine Studies, 10(5):569-591,
1978.
Abstract:
This paper
describes a text-to-speech translation system for the Italian language. It is
based on a formal translator which converts a graphemic text into the
corresponding phonemic representation and on a suprasegmental features
descriptor. The translator is implemented according to the formal techniques
developed for lexical and syntactical analysis of artificial languages. The
suprasegmental features descriptor determines pause positions, phoneme
durations and pitch contour on the sole basis of the punctuation marks and
the accent marks present in the text.
