Aims and Scope
PRUV 2018 is the Second Workshop on Logics for Reasoning about Preferences, Uncertainty, and Vagueness. This workshop follows a successful first edition (PRUV 2014), which culminated in a Special Issue of the IfCoLog Journal of Logics and their Applications.
Originally, managing preferences, uncertainty, and vagueness has in particular been explored in Artificial Intelligence. During the recent years, especially with the availability of massive amounts of data in different repositories and the possibility of integrating and exploiting these data, technologies for managing preferences, uncertainty, and vagueness have started to play a key role in other areas, such as databases and the (Social or Semantic) Web. These application areas have sparked another wave of strong interest into logics for dealing with preferences, uncertainty, and vagueness. Important examples are fuzzy and probabilistic approaches for description logics or rule systems for handling vagueness and uncertainty in the Semantic Web, or formalisms for handling user preferences in the context of ontological knowledge in the Social Semantic Web.
The aim of PRUV is to bring together people from different communities (such as the Artificial Intelligence and the Semantic Web community, among others), including theorists and practitioners, working on logics for reasoning about preferences, uncertainty, and vagueness.
Making researchers aware of and fruitfully discuss the most recent application areas, new challenges and the existing body of work on logics for reasoning about preferences, uncertainty, and vagueness, respectively is the main goal of this meeting.
PRUV welcomes submissions relating logic with preferences, uncertainty and vagueness. Some logics of interest are:
- first order logic,
- propositional logic,
- logic programming,
- answer set programming,
- description logics,
- modal logic,
- dynamic logic,
- temporal logics,
- agent logics.
Formalisms for handling preferences, uncertainty and vagueness include, but are not limited to
- probability measures,
- Bayesian networks,
- possibility measures,
- preference networks,
- rough sets,
- fuzzy set theory,
- similarity measures.
All accepted papers will be made available electronically at the CEUR Workshop Proceedings website (http://www.CEUR-ws.org/).
Double Submission Policy
The aim of the workshop is to bring together experts from a wide spectrum of research areas. Thus, we accept submissions of papers and results previously published in other major conferences and journals.

There are three submission formats:
- Full papers (up to 15 pages)
- Technical Communications (up to 8 pages)
- System Descriptions (up to 8 pages)

Title: Quantitative Logic Reasoning – Combining logical reasoning with probabilities and counting
Speaker: Marcelo Finger, University of Sao Paulo, Brazil
Abstract: We present a research program which investigates the intersection of deductive reasoning with explicit quantitative capabilities. These capabilities encompass probabilistic reasoning, counting and counting quantifiers, and similar systems. The need to have a combined reasoning system that enables a unified way of reasoning with quantities has always been recognized in modern logic, as proposals of probabilistic logic reasoning are present since the work of Boole . Equally ubiquitous is the need to deal with cardinality restrictions on finite sets. More recently, a well-founded probabilistic theory has been developed for non-classical settings as well, such as probabilistic reasoning over Lukasiewicz infinitely-valued logic.
We show that there is a common way to deal with these several deductive quantitative capabilities, involving a framework based on Linear Algebra and Linear Programming. The distinction between classical and non-classical reasoning on the one hand, and probabilistic and cardinality reasoning on the other hand, comes from the different family of algebras employed. The quantitative logic systems also allow for the introduction of inconsistency measurements, which quantify the degree of inconsistency of a given quantitative logic theory, following some basic principles of inconsistency measurements.
On the practical level, we aim at exploring quantitative logic systems in which the complexity of reasoning is “only NP-complete”. We provide open-source implementations for solvers operating over those systems and study some notable empirical properties, such as the present of a phase transition.
