XML is increasingly used to markup content in information repositories. Retrieval from XML document collections is now an area of active research. XML content retrieval poses a two-fold problem. One, finding effective techniques to retrieve the most useful XML elements in response to a user query. Two, devising an appropriate evaluation methodology to measure the effectivity of such techniques. This study examines both. Pivoted length normalization in VSM is revisited on benchmark XML collections. Performance improved. It is furthered by exploring query reformulation with an attempt to understand user's intent: what she wants and what she does not. On the evaluation, the sensitivity & robustness of various evaluation metrics along with reliability and reusability of the assessment pool used at INEX Ad-Hoc track since 2007 are studied in-depth. Large-scale experiments demonstrate that the INEX collections remain usable when evaluating non-participating systems. Finally, a low-cost pooling method based on query-specific variable pool-depth is proposed that proved effective in evaluation of both XML and document retrieval. Part of this work won the Best JASIST Paper Award 2011.

Welcome to the proceedings of the 8th Workshop of the Initiative for the Eva- ation of XML Retrieval (INEX)! Now in its eighth year, INEX is an established evaluation forum for XML information retrieval (IR), with over 100 organi- tions worldwide registered and over 50 groups participating actively in at least one of the tracks. INEX aims to provide an infrastructure, in the form of a large structured test collection and appropriate scoring methods, for the evaluation of focused retrieval systems. XML IR plays an increasingly important role in many information access systems (e.g., digitallibraries,Web, intranet) where content is a mixture oftext, multimedia, and metadata, formatted according to the adopted W3C standard for information repositories, the so-called eXtensible Markup Language (XML). The ultimate goal of such systems is to provide the right content to their e- users. However, while many of today s information access systems still treat documents as single large (text) blocks, XML o?ers the opportunity to exploit the internal structure of documents in order to allow for more precise access, thus providing more speci?c answers to user requests. Providing e?ective access to XML-based content is therefore a key issue for the success of these systems.

This book constitutes the thoroughly refereed post-conference proceedings of the 6th International Workshop of the Initiative for the Evaluation of XML Retrieval, INEX 2007, held at Dagstuhl Castle, Germany, in December 2007. The 37 revised full papers presented were carefully reviewed and selected for presentation at the workshop from 50 initial submissions. The papers are organized in an ad hoc track and 6 topical sections on book search, XML-mining, entity ranking, interactive, link-the-wiki, and multimedia.

I write with pleasurethis forewordto the proceedings of the 7th workshopof the Initiative for the Evaluation of XML Retrieval (INEX). The increased adoption of XML as the standard for representing a document structure has led to the development of retrieval systems that are aimed at e?ectively accessing XML documents. Providing e?ective access to large collections of XML documents is therefore a key issue for the success of these systems. INEX aims to provide the necessary methodological means and worldwide infrastructures for evaluating how good XML retrieval systems are. Since its launch in 2002, INEX has grown both in terms of number of p- ticipants and its coverage of the investigated retrieval tasks and scenarios. In 2002, INEX started with 49 registered participating organizations, whereas this number was more than 100 for 2008. In 2002, there was one main track, c- cerned with the ad hoc retrieval task, whereas in 2008, seven tracks in addition to the main ad hoc track were investigated, looking at various aspects of XML retrieval, from book search to entity ranking, including interaction aspects.
