Enhancing Content-And-Structure Information Retrieval using a Native XML Database [article]

Jovan Pehcevski, Anne-Marie Vercoustre
2005 arXiv   pre-print
Three approaches to content-and-structure XML retrieval are analysed in this paper: first by using Zettair, a full-text information retrieval system; second by using eXist, a native XML database, and third  ...  by using a hybrid XML retrieval system that uses eXist to produce the final answers from likely relevant articles retrieved by Zettair.  ...  Acknowledgements We would like to thank Wolfgang Meier for providing assistance and useful comments with using eXist, to Nick Lester, Falk Scholer and other members of the Search Engine Group at RMIT for  ...

Hybrid XML Retrieval: Combining Information Retrieval and a Native XML Database

Jovan Pehcevski, James A. Thom, Anne-Marie Vercoustre
2005 Information retrieval (Boston)  
This paper investigates the impact of three approaches to XML retrieval: using Zettair, a full-text information retrieval system; using eXist, a native XML database; and using a hybrid system that takes  ...  In the case of INEX 2003 relevance assessments for the content-only topics, our newly developed hybrid XML retrieval system is substantially more effective than either Zettair or eXist, and yields a robust  ...  Acknowledgements We thank Wolfgang Meier for his assistance with using eXist, and Nick Lester, Falk Scholer and other members of the Search Engine Group at RMIT for their support with using Zettair.  ...

Combining Indexing Schemes to Accelerate Querying XML on Content and Structure

Georgina Ramírez, Arjen P. de Vries
2004 Twente Data Management Workshop  
This talk focuses on retrieval models and methods for the document-centric view on XML and their evaluation within the INEX initiative.  ...  INEX has studied two types of tasks so far: 1. content-only (CO) queries are standard IR queries, where the system should retrieve the most specific elements answering the query;  ...  Acknowledgements We would like to thank Wolfgang Meier for providing assistance and useful comments with using eXist, to Nick Lester, Falk Scholer and other members of the Search Engine Group at RMIT for  ...

CSIRO's Participation in INEX 2006 [chapter]

Alexander Krumpholz, David Hawking
Lecture Notes in Computer Science  
In order to use CSIRO's plain text search engine PADRE[2] we had to preprocess the collection in a similar manner to the approach taken by our group in 2002 [3].  ...  In this year's INEX[1] participation, CSIRO participated in the Ad-hoc Track, contributing to three of the four given tasks, namely the Thorough Task, the Focussed Task and the Best in Context Task.  ...  In order to use the PADRE search engine we had to convert the official NEXI queries into PADRE queries.  ...
