This book constitutes the refereed proceedings of the 10th European Conference on Logics in Artificial Intelligence, JELIA 2006. The 34 revised full papers and 12 revised tool description papers presented together with 3 invited talks were carefully reviewed and selected from 96 submissions. The papers cover a range of topics within the remit of the Conference, such as logic programming, description logics, non-monotonic reasoning, agent theories, automated reasoning, and machine learning.

This volume presents the thoroughly revised proceedings of the IJCAI '93 Workshop on Executable Modal and Temporal Logics held in Chambery, France in August 1993.
The direct execution of logical statements, through languages such as PROLOG, has proved remarkably successful within CS and AI. In recent years a variety of nonclassical logics have been introduced and several executable forms of these logics have been applied to programming.
This volume addresses a range of approaches to executable modal and temporal logics, not only from a logical point of view, but also from programming...
