| Part 1 (Mohand-Said Hacid) : Formalisms for knowledge representation
The aim is to explore existing formalisms for knowledge representation and then to concentrate on description logics. We present syntaxes, semantics, reasonings and possible applications.
-
Objects
-
Logics
-
Object logics (e.g. : LIFE, F-Logic, …)
-
Description logics :
-
Syntax
-
Semantics
-
Reasoning (subsumption, satisfiability, LCS, Matching, …)
-
Algorithms
-
Applications : in databases, information systems, software engineering …
Part 2 (Emmanuel Coquery) : Constraints : Semantics, Algorithms and Techniques
This part aims to formally introduce the notion of constraint, especially through constraint logic programming, as well as to provide some algorithms and techniques used in constraint programming. The following points will be looked at:
Language:
-
Constraint domains
-
Constraint programming, semantics of constraint logic programs
-
Examples of constraint domains: finite domains, real and rationnals, types, calendars.
Algorithmics and resolution techniques:
-
Propagation algorithms: bound consistency, arc consistency
-
Constructive disjunction
-
Global constraints
-
Branch and bound
-
Enumeration heuristics (choice of variables and values).
Skills
This course allow students to acquire fundamentals in models, knowledge representation and reasoning. These are important prerequisite for tackling numerous research problems.
Methodological skills:
-
Being able to define problems requiring advanced techniques in knowloedge representation and data modelling.
-
Being able to identify appropriate algorithmic approaches that will serve as a base for proposing solutions to specific problems.
Technical skills:
