Das Buch ist eine Einführung 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 eingeführt. Die logischen Hintergründe 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 Prädikatenlogik zur logischen Programmiersprache Prolog nachvollzogen. Den Schluß bilden Anwendungen aus den Gebieten wissensbasierte Systeme und Computerlinguistik.

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 firmlyrooted in mathematical logic, yet it is also immenselypractical, as a growing number of users in universities,research institutes, and industry are realizing. Logicprogramming languages, specifically Prolog, have turned outto be ideal as prototyping and application developmentlanguages.This volume presents the proceedings of the Second LogicProgramming Summer School, LPSS'92. The First LogicProgramming Summer School, LPSS '90, addressed thetheoretical foundations of logic programming. This volumefocuses onthe relationship between theory and practice, andon practical applications.The introduction to the volume is by R. Kowalski, one of thepioneers in the field. The following papers are organizedinto sections on constraint logic programming, deductivedatabases and expert systems, processing of natural andformal languages, software engineering, and education.

Controlled natural languages (CNLs) are subsets of natural languages, obtained by - stricting the grammar and vocabulary in order to reduce or eliminate ambiguity and complexity. Traditionally, controlled languagesfall into two major types: those that - prove readability for human readers, and those that enable reliable automatic semantic analysis of the language. [. . . ] The second type of languages has a formal logical basis, i. e. they have a formal syntax and semantics, and can be mapped to an existing formal language, such as ?rst-order logic. Thus, those languages can be used as knowledge representation languages, and writing of those languages is supported by fully au- matic consistency and redundancy checks, query answering, etc. Wikipedia Variouscontrollednatural languagesof the second type have been developedby a n- ber of organizations, and have been used in many different application domains, most recently within the Semantic Web. The workshop CNL 2009 was dedicated to discussing the similarities and the d- ferences of existing controlled natural languages of the second type, possible impro- ments to these languages, relations to other knowledge representation languages, tool support, existing and future applications, and further topics of interest.

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 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.
