Structured queries in XML retrieval

Jaap Kamps, Maarten Marx, Maarten de Rijke, Börkur Sigurbjörnsson
2005 Proceedings of the 14th ACM international conference on Information and knowledge management - CIKM '05  
Our experimental analysis compares a structure-ignorant with a structure-aware retrieval approach using the test-suite of the 2004 edition of the INEX XML retrieval evaluation initiative.  ...  Third, the use of structure in queries functions as a precision enhancing device.  ...  As to querying structure, XML query languages such as XPath have a definite semantics.  ...

Managing structured queries in probabilistic XML retrieval systems

Luis M. de Campos, Juan M. Fernández-Luna, Juan F. Huete, Carlos Martín-Dancausa
2010 Information Processing & Management  
Focusing on the context of XML retrieval, in this paper we propose a general methodology for managing structured queries (involving both content and structure) within any given structured probabilistic  ...  of XML Retrieval (INEX).  ...  We have observed two types of approaches in the specialized bibliography for solving structured queries: those in which the retrieval of XML elements given a CAS query is integrated in the XML retrieval  ...

Why structural hints in queries do not help XML-retrieval

Andrew Trotman, Mounia Lalmas
2006 Proceedings of the 29th annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '06  
For many years it has been commonly held that a user who adds structural "hints" to a query will improve precision in an element retrieval search.  ...  We present the unexpected result that structural hints in queries do not improve precision.  ...  If these structures are marked up as XML elements then a search engine that returns these structures is an element retrieval system.  ...

Feedback-Driven Structural Query Expansion for Ranked Retrieval of XML Data [chapter]

Ralf Schenkel, Martin Theobald
2006 Lecture Notes in Computer Science  
In XML retrieval, feedback engines usually generate an expanded query from the content of elements marked as relevant or nonrelevant.  ...  This approach that is inspired by text-based IR completely ignores the semistructured nature of XML. This paper makes the important step from content-based to structural feedback.  ...  Conclusion and Future Work This paper has made important steps from content-based to structural feedback in XML retrieval.  ...

Refining Keyword Queries for XML Retrieval by Combining Content and Structure [chapter]

Desislava Petkova, W. Bruce Croft, Yanlei Diao
2009 Lecture Notes in Computer Science  
In this work, we propose an automatic query refinement method to transform a keyword query into structured XML queries that capture the original information need and conform to the underlying XML data.  ...  To assist its users, an XML retrieval system can have a keyword-based interface, relegating the task of combining textual and structural clues to the retrieval algorithm.  ...  However, structural hints in the input query would pose a difficulty for CO retrieval.  ...

Modelling Vague Content and Structure Querying in XML Retrieval with a Probabilistic Object-Relational Framework [chapter]

Mounia Lalmas, Thomas Rölleke
2004 Lecture Notes in Computer Science  
Many XML retrieval applications require relevance-oriented ranking of retrieved elements in order to capture the vagueness inherent to the information retrieval process.  ...  In this paper, we use a probabilistic object-relational framework to model representation and retrieval strategies that take into account vagueness at both content and structure level.  ...  This shows the importance attached to vague structure querying for relevance-oriented XML retrieval.  ...

Querying XML using structures and keywords in timber

Cong Yu, H. V. Jagadish, Dragomir R. Radev
2003 Proceedings of the 26th annual international ACM SIGIR conference on Research and development in informaion retrieval - SIGIR '03

A CONTENT-BASED APPROACH TO RELEVANCE FEEDBACK IN XML-IR FOR CONTENT AND STRUCTURE QUERIES

Retrieving information chunks from a repository of documents' SIT Collected from heterogeneous sources

Raad Alwan, Baydaa Al-Hamadani
2015 INTERNATIONAL JOURNAL OF COMPUTERS & TECHNOLOGY  
XML documents are generated from heterogeneous resources. They may share the same data but in different Schema, which make it difficult to retrieve information from them.  ...  In this paper we propose a new technique that first; minimizes the size of the XML documents by reducing the redundancy of the structure part and generate the repository for these documents, and second  ...  XML RETRIEVAL XML documents are semi-structured and the retrieval techniques from such documents are more precise than retrieving information from structured documents [1] .  ...
