This book constitutes the refereed proceedings of the Third International Workshop on Controlled Natural Language, CNL 2012, held in Zurich, Switzerland, in August 2012. The 12 revised papers presented in this volume were carefully reviewed and selected from numerous submissions. The papers are organized in topical sections on CNL for knowledge representation, CNL for interactive systems, CNL applications, CNL grammars and lexica, CNL in the context of the Semantic Web and Linked Open Data and CNL use cases.

This book constitutes the refereed proceedings of the Second International Workshop on Controlled Natural Language, CNL 2010, held in Marettimo Island, Italy, in September 2010. The 9 revised papers presented in this volume, together with 1 tutorial, were carefully reviewed and selected from 17 initial submissions. They broadly cover the field of controlled natural language, stressing theoretical and practical aspects of CNLs, relations to other knowledge representation languages, tool support, and applications.

This volume contains the papers from the Seventh International Workshop on Logic Program Synthesis and Transformation, LOPSTR '97, that took place in Leuven, Belgium, on July 10-12, 1997, 'back to back' with the Fourteenth International Conference on Logic Programming, ICLP '97. Both ICLP and LOPSTR were organised by the K.U. Leuven Department of Computer Science. LOPSTR '97 was sponsored by Compulog Net and by the Flanders Research Network on Declarative Methods in Computer Science. LOPSTR '97 had 39 participants from 13 countries. There were two invited talks by Wolfgang Bibel (Darmstadt) on 'A multi level approach to program synthesis', and by Henning Christiansen (Roskilde) on 'Implicit program synthesis by a reversible metainterpreter'. Extended versions of both talks appear in this volume. There were 19 technical papers accepted for presentation at LOPSTR '97, out of 33 submissions. Of these, 15 appear in extended versions in this volume. Their topics range over the fields of program synthesis, program transformation, program analysis, tabling, metaprogramming, and inductive logic programming.

Logic programming enjoys a privileged position. It is firmly rooted in mathematical logic, yet it is also immensely practical, as a growing number of users in universities, research institutes, and industry are realizing. Logic programming languages, specifically Prolog, have turned out to be ideal as prototyping and application development languages. This volume presents the proceedings of the Second Logic Programming Summer School, LPSS'92. The First Logic Programming Summer School, LPSS '90, addressed the theoretical foundations of logic programming. This volume focuses onthe relationship between theory and practice, and on practical applications. The introduction to the volume is by R. Kowalski, one of the pioneers in the field. The following papers are organized into sections on constraint logic programming, deductive databases and expert systems, processing of natural and formal languages, software engineering, and education.

Das Buch ist eine Einfuhrung in die logische Programmierung in der Form eines Kurses, in dem die Grundlagen der logischen Programmierung, die logische Programmiersprache Prolog und ihre Programmierpraxis, sowie einige Anwendungen vorgestellt werden. Nach einer kurzen Begriffsbestimmung der logischen Programmierung wird das sogenannte reine Prolog als Programmiersprache anhand von Beispielen eingefuhrt. Die logischen Hintergrunde werden dabei nur angedeutet. Anschliessend werden die Erweiterungen vorgestellt, die Prolog zur vollen Programmiersprache machen. Es folgen etablierte Programmiertechniken, die Prolog wie jede andere Programmiersprache besitzt. Mit diesen Vorkenntnissen ist es nun leichter, die theoretischen Grundlagen der logischen Programmierung zu verstehen. Es wird gezeigt, wie Logik zur Wissensdarstellung und zur Ableitung von weiterem Wissen verwendet werden kann. Ferner wird der Weg von der Pradikatenlogik zur logischen Programmiersprache Prolog nachvollzogen. Den Schluss bilden Anwendungen aus den Gebieten wissensbasierte Systeme und Computerlinguistik."
