A Knowledge-based Image Retrieval System Integrating Semantic and Visual Features

Olfa Allani, Hajer Baazaoui Zghal, Nedra Mellouli, Herman Akdag
2016 Procedia Computer Science  
The idea is to automatically build a modular ontology for semantic information and organize visual features in a graph-based model.  ...  Both elements are then combined together in a same component called "pattern" used for retrieval.  ...  There are approaches that aim to expand the level of information by extracting a semantic level given the visual information; approaches based on users feedback (relevance feedback) and approaches bringing  ...

A Fusion Approach to XML Structured Document Retrieval

Ray R. Larson
2005 Information retrieval (Boston)  
In this research, and in the Cheshire II system used for the research, we define a document component, or simply component, as a continuous segment of an XML document representing some part of an XML document  ...  The XML retrieval problem (as formulated for the Initiative for the Evaluation of XML Retrieval or INEX) (Fuhr et al., 2002) is to retrieve not only complete documents, but also the component parts of  ...  The basic approach used in INEX and in the current evaluation was to combine the results of searching different document components and different probabilistic retrieval algorithms within single search  ...

POSTECH Question-Answering Experiments at NTCIR4-QAC

Seung-Hoon Na, In-Su Kang, Jong-Hyeok Lee
2004 NTCIR Conference on Evaluation of Information Access Technologies  
Our QA system consisting of these basic components showed a weak performance in NTCIR-4, but obtained high performance in pure answer extraction.  ...  Passage retrieval was performed by a density-based ranking method based on importance of query terms occurred in the passage.  ...  This concept code information covers all lexical words that belong to hypo-concepts of concept code 5 (level 2) in Kadokawa thesaurus [10] , which has a 4-level hierarchy of about 1,100 semantic classes  ...

The MiPACQ clinical question answering system

Brian L Cairns, Rodney D Nielsen, James J Masanz, James H Martin, Martha S Palmer, Wayne H Ward, Guergana K Savova
2011 AMIA Annual Symposium Proceedings  
The Multi-source Integrated Platform for Answering Clinical Questions (MiPACQ) is a QA pipeline that integrates a variety of information retrieval and natural language processing systems into an extensible  ...  Compared with our baseline information retrieval system, the MiPACQ rule-based system demonstrates 84% improvement in Precision at One and the MiPACQ machine-learning-based system demonstrates 134% improvement  ...  However, given that medical information retrieval systems generally return results only at a coarse level, and given that clinicians have a minimal amount of time to search for answersoften as little as  ...

Theoretical benchmarks of XML retrieval

Tobias Blanke, Mounia Lalmas
2006 Proceedings of the 29th annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '06  
To this end, a Situation Theory framework for the meta-evaluation of XML retrieval is presented.  ...  This poster investigates the use of theoretical benchmarks to describe the matching functions of XML retrieval systems and the properties of specificity and exhaustivity in XML retrieval.  ...  To evaluate how effective XML retrieval approaches are, it is therefore necessary to consider whether the 'right' level is correctly identified.  ...

Christopher C. Yang, Wai Lam
2006 Journal of the American Society for Information Science and Technology  
These components are namely multilingual resources, machine translation, cross-lingual information retrieval, multilingual information extraction and summarization, and user evaluations and studies.  ...  Parallel and comparable corpora are important for generating a statistical translation model to overcome the limitations of a manually generated dictionary.  ...  Information extraction from documents aims at extracting short text fragments with certain semantic information. A common approach to information extraction is to develop a set of extraction rules.  ...
