Welcome to the proceedings of the 6th workshop of the Initiative for the Ev- uation of XML Retrieval (INEX) Now in its sixth year, INEX has become an established evaluation forum for XML information retrieval (IR), with over 100 participating organizations worldwide. Its aim is to provide an infrastructure, in the form of a large XML test collection and appropriate scoring methods, for the evaluation of XML IR systems. XMLIRis playinganincreasinglyimportantroleinmanyinformationaccess systems(e.g., digitallibraries, web, intranet)wherecontentisbecomingmoreand more a mixture of text, multimedia, and metadata, formatted according to the adopted W3C standard for information repositories, the so-called eXtensible MarkupLanguage(XML).Theultimategoalofsuchsystemsistoprovidetheright contenttotheirend-users.However, whilemanyoftoday'sinformationaccesss- temsstilltreatdocumentsassinglelarge(text)blocks, XMLo?erstheopportunity toexploittheinternalstructureofdocumentsinordertoallowformoreprecise- cess, thusprovidingmorespeci?canswerstouserrequests.Providinge?ective- cesstoXML-basedcontentisthereforeakeyissueforthesuccessofthesesystems. The aim of the INEX 2007 workshop was to bring together researchers in the ?eld of XML IR who participated in the INEX 2007 campaign. During the past year participating organizations contributed to the building of a large-scale XML test collection by creating topics, performing retrieval runs and providing relevance assessments. The workshop brought together the results of this lar- scale e?ort, summarized and addressed the issues encountered, and devised a work plan for the future evaluation of XML retrieval systems. In total sevenresearchtrackswereincluded in INEX 2007.Thesestudied d- ferentaspectsofXMLinformationaccess: ad-hoc, documentmining, multimedia, heterogeneous, entity ranking, book search, and link-the-wiki. The consolidation of the existing tracks, and the expansion to new areas o?ered by the new tracks has enabled INEX to extend its scope. This volume contains 37 papers selected from 50 submitted ones (74% acceptance rate). Each paper was peer-re

This book constitutes the thoroughly refereed post-proceedings of the 5th International Workshop of the Initiative for the Evaluation of XML Retrieval, INEX 2006, held at Dagstuhl Castle, Germany, in December 2006.

The 49 revised full papers presented were carefully selected for presentation at the workshop and went through a subsequent round of careful reviewing and revision. The papers are organized in topical sections on methodology, and 7 additional tracks on ad-hoc, natural language processing, heterogeneous collection, multimedia, interactive, use case, as well as document mining.

This book constitutes the refereed proceedings of the 11th European Conference on Research and Advanced Technology for Digital Libraries, ECDL 2007, held in Budapest, Hungary, in September 2007.

The 36 revised full papers presented together with the extended abstracts of 36 revised poster, demo papers and 2 panel descriptions were carefully reviewed and selected from a total of 153 submissions. The papers are organized in topical sections on ontologies, digital libraries and the web, models, multimedia and multilingual DLs, grid and peer-to-peer, preservation, user interfaces, document linking, information retrieval, personal information management, new DL applications, and user studies.

This book constitutes the thoroughly refereed post-proceedings of the 4th International Workshop of the Initiative for the Evaluation of XML Retrieval, INEX 2005, held at Dagstuhl Castle, Germany, in November 2005. The book presents 41 revised full papers, organized in topical sections on methodology, multiple retrieval, ad-hoc retrieval, relevance feedback, natural language queries, and more heterogeneous retrieval, interactive retrieval, document mining, and multimedia retrieval.

The ultimate goal of many information access systems (e.g., digital libraries, the Web, intranets) is to provide the right content to their end-users. This content is increasingly a mixture of text, multimedia, and metadata, and is formatted according to the adopted W3C standard for information repositories, the so-called eXtensible Markup L- guage (XML). Whereas many of today s information access systems still treat do- ments as single large (text) blocks, XML offers the opportunity to exploit the internal structure of documents in order to allow for more precise access thus providing more specific answers to user requests. Providing effective access to XML-based content is therefore a key issue for the success of these systems. The aim of the INEX campaign (Initiative for the Evaluation of XML Retrieval), which was set up at the beginning of 2002, is to establish infrastructures, XML test suites, and appropriate measurements for evaluating the performance of information retrieval systems that aim at giving effective access to XML content. More precisely, the goal of the INEX initiative is to provide means, in the form of a large XML test collection and appropriate scoring methods, for the evaluation of content-oriented XML retrieval systems."

This book constitutes the refereed proceedings of the 7th International Conference of the CLEF Initiative, CLEF 2016, held in Toulouse, France, in September 2016. The 10 full papers and 8 short papers presented together with 5 best of the labs papers were carefully reviewed and selected from 36 submissions. In addition to these talks, this volume contains the results of 7 benchmarking labs reporting their year long activities in overview talks and lab sessions. The papers address all aspects of information access in any modality and language and cover a broad rangeof topics in the fields of multilingual and multimodal information access evaluation.

This book constitutes the proceedings of the 20th International Conference on Theory and Practice of Digital Libraries, TPDL 2016, held in Hannover, Germany, in September 2016. The 28 full papers, 5 posters and 8 short papers presented in this volume were carefully reviewed and selected from 93 submissions. They were organized in topical sections named: Digital Library Design; User Aspects; Search; Web Archives; Semantics; Multimedia and Time Aspects; Digital Library Evaluation; Digital Humanities; e-Infrastructures.

This book constitutes the proceedings of the 37th European Conference on IR Research, ECIR 2015, held in Vienna, Austria, in March/April 2015. The 44 full papers, 41 poster papers and 7 demonstrations presented together with 3 keynotes in this volume were carefully reviewed and selected from 305 submissions. The focus of the papers were on following topics: aggregated search and diversity, classification, cross-lingual and discourse, efficiency, evaluation, event mining and summarisation, information extraction, recommender systems, semantic and graph-based models, sentiment and opinion, social media, specific search tasks, temporal models and features, topic and document models, user behavior and reproducible IR.

This two-volume set LNCS 11437 and 11438 constitutes the refereed proceedings of the 41st European Conference on IR Research, ECIR 2019, held in Cologne, Germany, in April 2019.
