Cumulated Gain-based Evaluation of IR Techniques
- ACM Transactions on Information Systems
, 2002
"... Modem large retrieval environments tend to overwhelm their users by their large output. Since all documents are not of equal relevance to their users, highly relevant documents should be identified and ranked first for presentation to the users. In order to develop IR techniques to this direction, i ..."

On Penalising Late Arrival of Relevant Documents in Information Retrieval Evaluation with Graded Relevance
- Proceedings of the First Workshop on Evaluating Information Access (EVIA 2007
, 2007
"... Large-scale information retrieval evaluation efforts such as TREC and NTCIR have tended to adhere to binary-relevance evaluation metrics, even when graded relevance data were available. However, the NTCIR-6 Crosslingual Task has finally started adopting graded-relevance metrics, though only as addit ..."

This paper compares three existing graded-relevance metrics that were mentioned in the Call for Participation of the NTCIR-6 Crosslingual Task in terms of the ability to control how severely “late arrival ” of relevant documents should be penalised. We argue and demonstrate that Q
Unordered Documents
"... Semantic search has been one of the major envisioned benefits of the Semantic Web since its emergence in the late 90’s [1]. Our demo shows a proposal towards this goal. One way to view a semantic search engine is as a tool that gets formal queries (e.g. in RDQL, RQL, SPARQL, or the like) from a clie ..."

in the Semantic Web, a search engine returns documents, rather than (or in addition to) exact values, in response to user queries. The engine should rank the documents, according to conceptbased relevance criteria. The overall retrieval process is illustrated in Figure 1 (see [3] for more details of our research
Controlling the Penalty on Late Arrival of Relevant Documents in Information Retrieval Evaluation with Graded Relevance Abstract
"... Large-scale information retrieval evaluation efforts such as TREC and NTCIR have always used binary-relevance evaluation metrics, even when graded relevance data were available. However, the NTCIR-6 crosslingual task has finally announced that it will use graded-relevance metrics, though only as add ..."

as additional metrics. This paper compares graded-relevance metrics in terms of the ability to control the balance between retrieving highly relevant documents and retrieving any relevant documents early in the ranked list. We argue and demonstrate that Q-measure is more flexible than normalised Discounted
User performance versus precision measures for simple search tasks
- Noriko Kando, Wessel Kraaij and Arjen P. de Vries (editors), Proceedings of the ACM SIGIR International Conference on Research and Development in Information Retrieval
, 2006
"... Several recent studies have demonstrated that the type of improvements in information retrieval system effectiveness reported in forums such as SIGIR and TREC do not trans-late into a benefit for users. Two of the studies used an instance recall task, and a third used a question answering task, so p ..."

Computerized Retrieval and Classification: An application to Reasons for Late Filings with the Securities and Exchange Commission
"... This study explores a system to retrieve and classify the reasons for late mandatory SEC (Securities and Exchange Commission) filings. From the source documents, the system identifies the reasons for the late filing and classifies them into one or more of seven categories. The system can be used by ..."

An Index Structure To Retrieve Documents With Geographic Information

Lately, a new research field called Geographic Information Retrieval has appeared from the intersection of these two fields. The main goal of this field is to define index structu ..."

Conceptualizing oral documents
"... Conclusion. I argue for increasing our understanding of artefacts derived from oral information, like oral documents. Doing so may lead to further insight into documents, information artefacts born from other modalities, as well as preferences for using specific types of information modalities. Int ..."

. Introduction Document Studies, with its focus on tangible forms of evidence, has allowed us to better understand issues involved in the systematic transmission, storage, and retrieval of informational objects. Indeed, its focus on the artefacts "containing" information has provided us
