In this paper we present the results of the evaluation of an information retrieval system constructed in the Faculty of Computer Science, BUAP. This system was used in the Data-Centric track of the Initiative for the Evaluation of XML retrieval (INEX 2010). This track is focused on the extensive use of a very rich structure of the documents beyond the content. We have considered topics (queries...

We describe the runs for our participation in the Search sub-task of the Search and Hyperlinking Task at MediaEval 2012. Our runs are designed to form a retrieval baseline by using time-based segmentation of audio transcripts incorporating pause information and a sliding window to define the retrieval segments boundaries with a standard language modelling information retrieval strategy. Using t...

This paper describes the work done by Priberam in the development of a question answering (QA) system for Portuguese. The system was built using the company’s NLP workbench and information retrieval technology. Special focus is given to the question analysis, document and sentence retrieval, and answer extraction stages. The paper discusses the system’s performance in the context of the QA@CLEF...

there is heavy usage of Internet-based information resource platformsdue to the COVID-19 pandemic. If it can present search results as a list groupsof related terms and context, that would be ideal. An additional enhancement display in classified manner. Therefore, research proposing an effective efficient retrieval system. The methodology adopted follows conventional Information Retrieval (IR)...

DEFINITION An evaluation metric is used to evaluate the effectiveness of information retrieval systems and to justify theoretical and/or pragmatical developments of these systems. It consists of a set of measures that follow a common underlying evaluation methodology. There are many metrics that can be used to evaluate the effectiveness of semi-structured text retrieval systems. These metrics a...

The general photographic ad-hoc retrieval task of the ImageCLEF 2007 evaluation campaign is described. This task provides both the resources and the framework necessary to perform comparative laboratory-style evaluation of visual information retrieval from generic photographic collections. In 2007, the evaluation objective concentrated on retrieval of lightly annotated images, a new challenge t...

We present the Visual Information Retrieval Tool for Upfront Evaluation (VIRTUE) which is an interactive and visual system supporting two relevant phases of the experimental evaluation process: performance analysis and failure analysis.
