This volume contains the lecture notes of the 9th Reasoning Web Summer School 2013, held in Mannheim, Germany, in July/August 2013. The 2013 summer school program covered diverse aspects of Web reasoning, ranging from scalable lightweight formalisms such as RDF to more expressive ontology languages based on description logics. It also featured foundational reasoning techniques used in answer set programming and ontology-based data access as well as emerging topics like geo-spatial information handling and reasoning-driven information extraction and integration.

The contributions are organized in topical sections named: foundations of computer science; software and Web engineering; cryptography, security, and verification; and artificial intelligence.

The topic of logic programming and databases. has gained in creasing interest in recent years. Several events have marked the rapid evolution of this field: the selection, by the Japanese Fifth Generation Project, of Prolog and of the relational data model as the basis for the development of new machine archi tectures; the focusing of research in database theory on logic queries and on recursive query processing; and the pragmatic, application-oriented development of expert database systems and of knowledge-base systems. As a result, an enormous amount of work has been produced in the recent literature, coupled with the spontaneous growth of several advanced projects in this area. The goal of this book is to present a systematic overview of a rapidly evolving discipline, which is presently not described with the same approach in other books. We intend to introduce stu dents and researchers to this new discipline; thus we use a plain, tutorial style, and complement the description of algorithms with examples and exercises. We attempt to achieve a balance be tween theoretical foundations and technological issues; thus we present a careful introduction to the new language Datalog, but we also focus on the efficient interfacing of logic programming formalisms (such as Prolog and Datalog) with large databases.

The 1998Annual Conference of the EuropeanAssociation for Computer Science Logic, CSL'98, was held in Brno, Czech Republic, during August 24-28, 1998. CSL'98wasthe12thinaseriesofworkshopsandthe7thtobeheldasthe Annual Conference of the EACSL. The conference was organized at Masaryk University in Brno by the Faculty of Informatics in cooperation with universities in Aaachen, Caen, Haagen, Linz, Metz, Pisa, Szeged, Vienna, and other institutions. CSL'98 formed one part of a federated conferences event, the other part being MFCS'98, the 23rd Int- national Symposium on the Mathematical Foundations of Computer Science. This federated conferences event consisted of common plenary sessions, invited talks, several parallel technical programme tracks, a dozen satellite workshops organized in parallel, and tutorials. The Federated CSL/MFCS'98 Conferences event included 19 invited talks, four of them joint CSL/MFCS'98 talks (D. Harel, W. Maass, Y. Matiyasevic, and M. Yannakakis), four for CSL (P. Hajek, J. Mitchell, Th. Schwentick, and J. Tiuryn), and eleven for MFCS. Last but not least, two tutorials were organized by CSL on the day preceding the symposium on "Inference Rules in Fragments of Arithmetic" by Lev Beklemishev and on "Proofs, Types, and Safe Mobile Code" by Greg Morrisett. A total of 345 persons attended the Federated CSL/MFCS'98 Conference which was a great success. The program committee of CSL'98 selected 27 of 74 papers submitted for the conference.From the 27 papers selected for presentation,25 havebeen accepted, following the standard refereeeing procedure, for publication in the present p- ceedings. Three invited speakers submitted papers, that were likewise refereeed and accepted.

This book constitutes the refereed proceedings of the 5th Kurt G del Colloquium on Computational Logic and Proof Theory, KGC '97, held in Vienna, Austria, in August 1997.
The volume presents 20 revised full papers selected from 38 submitted papers. Also included are seven invited contributions by leading experts in the area. The book documents interdisciplinary work done in the area of computer science and mathematical logics by combining research on provability, analysis of proofs, proof search, and complexity.

This volume presents the proceedings of the 1995 International Conference on Database Theory, ICDT '95, held in Prague in January 1995.
Besides two full invited papers and the abstracts of two tutorials, the book includes the revised full versions of 29 technical contributions selected from a total of 116 submissions. The papers address all current aspects of database theory; they are organized in sections on optimization, nonmonotonic semantics, query languages, concurrency control, advanced models, probabilistic methods, constraints and dependencies, and Datalog analysis.

The Third Kurt G-del Symposium, KGC'93, held in Brno, Czech Republic, August1993, is the third in a series of biennial symposia on logic, theoretical computer science, and philosophy of mathematics. The aim of this meeting wasto bring together researchers working in the fields of computational logic and proof theory. While proof theory traditionally is a discipline of mathematical logic, the central activity in computational logic can be foundin computer science. In both disciplines methods were invented which arecrucial to one another. This volume contains the proceedings of the symposium. It contains contributions by 36 authors from 10 different countries. In addition to 10 invited papers there are 26 contributed papers selected from over 50 submissions.

These are the proceedings of the third International conference on ExtendingDatabase Technology (EDBT) held in Vienna in March 1992. The success of the 1988 and 1990 conferences held in Venice suggested that there is room for a major international database conference in Europe every two years, to serve as a forum for presentation of new results in research, developmentand applications extending the state of the art in database technology. The 1992 EDBT conference has attracted a lot of interest. This volume contains 33 papers selected from 220 papers submitted by authors from more than 30 countries, including invited papers by F. Bancilhon and R. Reiter. The volume is organized into sections on: visual interfaces and multimedia techniques, deductive databases, schema updatability, object-oriented databases, updating in deductive databases and knowledge bases, indexing techniques, parallel processing, distributed databases, knowledge bases, transaction processing, and query processing.

The goal of the International Workshop on Expert Systems in Engineering is to stimulate the flow of information between researchers working on theoretical and applied research topics in this area. It puts special emphasis on new technologies relevant to industrial engineering expert systems, such as model-based diagnosis, qualitative reasoning, planning, and design, and to the conditions in which they operate, in real time, with database support. The workshop is especially relevant for engineering environments like CIM (computer integrated manufacturing) and process automation.
