A Fusion Approach to XML Structured Document Retrieval

Ray R. Larson
2005 Information retrieval (Boston)  
The basic notion of "data fusion" or "meta-search" approaches to IR is quite simple and intuitively appealing.  ...  In the research reported here, we examine the application of data fusion methods to the XML retrieval problem.  ...  In this paper we have examined the fusion of different algorithms and document components in content-oriented and content and structure XML retrieval.  ...

Kinship contextualization

Muhammad A. Norozi, Paavo Arvola
2013 Proceedings of the 36th international ACM SIGIR conference on Research and development in information retrieval - SIGIR '13  
In this study we hypothesize that the context of an XML-element originated from its preceding and following elements in the sequential ordering of a document improves the quality of retrieval.  ...  In the tree form of the document's structure, kinship contextualization means, contextualization based on the horizontal and vertical elements in the kinship tree, or elements in closer to a wider structural  ...  XML documents are used as a sample case of semi-structured documents, these documents have hierarchical structure, which is often represented in a form of tree.  ...

Information Retrieval of Sequential Data in Heterogeneous XML Databases [chapter]

Eugen Popovici, Pierre-François Marteau, Gildas Ménier
2006 Lecture Notes in Computer Science  
In this article we introduce a retrieval scheme designed to manage sequential data in an XML context based on two levels of approximation: on the structural localization/organization of the sequential  ...  The XML documents evolved from plain structured text representations, to documents having complex and heterogeneous structures and contents: video descriptions, mathematical formulas, time series or sequences  ...  A general opinion [8] and also our belief is that using similarity operators adapted to the document content types and to the XML structure in the retrieval process will improve the precision of the  ...

Combining structured and unstructured information in a retrieval model for accessing legislation

Marie-Francine Moens
2005 Proceedings of the 10th international conference on Artificial intelligence and law - ICAIL '05  
Such an approach is very promising for the retrieval of legal documents. This is illustrated with two retrieval models specifically designed for the retrieval of legislation.  ...  Legal documents typically combine structured and unstructured information, the former being tagged with markup languages such as XML (Extensible Markup Language).  ...  With regard to information retrieval from document-centric XML data, the research community has exhibited a large interest in XML retrieval models.  ...

Finding Relevant Passages in Scientific Articles: Fusion of Automatic Approaches vs. an Interactive Team Effort

Dina Demner-Fushman, Susanne M. Humphrey, Nicholas C. Ide, Russell F. Loane, Patrick Ruch, Miguel E. Ruiz, Lawrence H. Smith, Lorraine K. Tanabe, W. John Wilbur, Alan R. Aronson
2006 Text Retrieval Conference  
To continue using our TREC 2005 fusion approach, we needed a common representation for the full text biomedical articles to be shared by the four base systems (Essie, SMART, EasyIR and Theme.)  ...  This paper presents our approach to retargeting the information retrieval systems designed and/or optimized for retrieval of MEDLINE citations to the task of finding relevant passages in the text of scientific  ...  This latter strategy has been shown to be very effective but relies on a structured XML document format that is not always available.  ...

When is the Structural Context Effective?

Muhammad Ali Norozi, Paavo Arvola
2013 Dutch-Belgian Workshop on Information Retrieval  
Search and Retrieval]: Search process INTRODUCTION Document parts, referred to as elements, have both a hierarchical and a sequential relationship with each other.  ...  In focused retrieval, the use of context is a driving force to alleviate or "un-bias" the retrieval of items with varying length.  ...  The tree-structure of the XML document (Figure 1 ) is assumed to be a graph.  ...
