Hidden Uncertainty in the Logical Representation of Desires
نویسندگان
چکیده
In this paper we introduce and study a logic of desires. The semantics of our logic is defined by means of two ordering relations representing preference and normality as in Boutilier’s logic QDT. However, the desires are interpreted in a different way: “in context A, I desire B” is interpreted as “the best among the most normal A∧B worlds are preferred to the most normal A ∧ ¬B worlds”. We study the formal properties of these desires, illustrate their expressive power on several classes of examples and position them with respect to previous work in qualitative decision theory.

متن کاملBalios - The Engine for Bayesian Logic Programs
Inductive Logic Programming (ILP) [4] combines techniques from machine learning with the representation of logic programming. It aims at inducing logical clauses, i.e, general rules from specific observations and background knowledge. Because of focusing on logical clauses, traditional ILP systems do not model uncertainty explicitly. On the other hand, state-of-the-art probabilistic models such...
متن کاملConsidering Uncertainty in Modeling Historical Knowledge
Simplifying and structuring qualitatively complex knowledge, quantifying it in a certain way to make it reusable and easily accessible are all aspects that are not new to historians. Computer science is currently approaching a solution to some of these problems, or at least making it easier to work with historical data. In this paper, we propose a historical knowledge representation model takin...
