Description logics are embodied in several knowledge-based systems and are used to develop various real-life applications. Now in paperback, The Description Logic Handbook provides a thorough account of the subject, covering all aspects of research in this field, namely: theory, implementation, and applications. Its appeal will be broad, ranging from more theoretically oriented readers, to those with more practically oriented interests who need a sound and modern understanding of knowledge representation systems based on description logics. As well as general revision throughout the book, this new edition presents a new chapter on ontology languages for the semantic web, an area of great importance for the future development of the web. In sum, the book will serve as a unique resource for the subject, and can also be used for self-study or as a reference for knowledge representation and artificial intelligence courses.

This book constitutes the proceedings of the International Joint Conference on Rules and Reasoning, RuleML+RR 2019, held in Bolzano, Italy, during September 2019. This is the third conference of a new series, joining the efforts of two existing conference series, namely “RuleML” (International Web Rule Symposium) and “RR” (Web Reasoning and Rule Systems).The 10 full research papers presented together with 5 short technical communications papers were carefully reviewed and selected from 26 submissions.

This three-volume set, LNCS 13421, 13422 and 13423, constitutes the thoroughly refereed proceedings of the 6th International Joint Conference, APWeb-WAIM 2022, held in Nanjing, China, in August 2022.The 75 full papers presented together with 45 short papers, and 5 demonstration papers were carefully reviewed and selected from 297 submissions.

This book constitutes the thoroughly refereed proceedings of the 11th Italian Research Conference on Digital Libraries, IRCDL 2015, held in Bozen-Bolzano, Italy, in January 2015.The 13 full papers, 4 short papers and 2 invited poster papers presented were carefully selected from 19 submissions. They are organized under the following five categories: semantic modeling; projects; models and applications; content analysis; and digital libraries infrastructures. The papers deal with numerous multidisciplinary aspects ranging from computer science to humanities in the broader sense, including research areas such as archival and library information sciences; information management systems; semantic technologies; information retrieval; new knowledge environments; new organizational/business models.

This volume contains some lecture notes of the 12th Reasoning Web Summer School (RW 2016), held in Aberdeen, UK, in September 2016.In 2016, the theme of the school was “Logical Foundation of Knowledge Graph Construction and Query Answering”. The notion of knowledge graph has become popular since Google started to use it to improve its search engine in 2012. Inspired by the success of Google, knowledge graphs are gaining momentum in the World Wide Web arena. Recent years have witnessed increasing industrial take-ups by other Internet giants, including Facebook's Open Graph and Microsoft's Satori. The aim of the lecture note is to provide a logical foundation for constructing and querying knowledge graphs. Our journey starts from the introduction of Knowledge Graph as well as its history, and the construction of knowledge graphs by considering both explicit and implicit author intentions. The book will then cover various topics, including how to revise and reuseontologies (schema of knowledge graphs) in a safe way, how to combine navigational queries with basic pattern matching queries for knowledge graph, how to setup a environment to do experiments on knowledge graphs, how to deal with inconsistencies and fuzziness in ontologies and knowledge graphs, and how to combine machine learning and machine reasoning for knowledge graphs.

This volume collects the papers presented at ICDT 2003, the 9th International ConferenceonDatabaseTheory,heldfrom8to10January2003intheRettorato dell'Universit' a di Siena, Siena, Italy. ICDT (http://alpha.luc.ac.be/"lucp1080/icdt/) has now a long t- dition of international conferences, providing a biennial scienti?c forum for the communicationofhigh-qualityresearchresultsontheoreticalaspectsofallforms of database systems and database technology. ICDT is traditionally held in - storic European locations: Rome in 1986, Bruges in 1988, Paris in 1990, Berlin in 1992, Prague in 1995, Delphi in 1997, Jerusalem in 1999, and London in 2001. ICDThasmergedwiththeSymposiumonMathematicalFundamentalsofDa- base Systems (MFDBS), initiated in Dresden in 1987, and continued in Visegrad in 1989 and Rostock in 1991. This volume contains 26 papers selected from 92 submissions, plus three invited papers by Hector Garcia-Molina, Yannis Ioannidis, and Limsoon Wong. We wish to thank all the authors who submitted papers, the members of the program committee for their e?orts in reviewing and selecting the papers, the external referees, the organizing committee, and the sponsors for their support.Diego Calvanese Maurizio Lenzerini Rajeev Motwani Organization ICDT 2003 was organized by the Dipartimento di Informatica e Sistemistica, Universit' a di Roma "La Sapienza".
