Versioning a full-text information retrieval system

Peter G. Anick, Rex A. Flynn
1992 Proceedings of the 15th annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '92  
In this paper, we present an approach to the incorporation of object versioning into a distributed full-text information retrieval system.  ...  We propose an implementation based on "partially versioned' index sets, arguing that its space overhead and querytime performance make it suitable for full-text IR, with its heavy dependence on inverted  ...  typically imposed by full-text information retrieval applications.  ...

Fast Incremental Indexing for Full-Text Information Retrieval

Eric W. Brown, James P. Callan, W. Bruce Croft
1994 Very Large Data Bases Conference  
Full-text information retrieval systems have traditionally been designed for archival environments.  ...  Modem applications, such as information filtering, operate in dynamic environments that require frequent additions to document collections.  ...  Introduction Full-text information retrieval (IR) systems are well established tools for satisfying a user's information need when the information base is a relatively static collection of documents.  ...

Full-text indexing and information retrieval in P2P systems

Odysseas Papapetrou
2008 Proceedings of the 2008 EDBT Ph.D. workshop on - Ph.D. '08  
The high dynamics in these networks and the high cost for building and maintaining indices over Distributed Hashtables make full text indexing and information processing difficult to scale for large P2P  ...  INTRODUCTION The focus of this thesis is to study the problem of efficient high-quality Information Retrieval (IR) over P2P networks.  ...  The new architecture does not reduce the Information Retrieval quality as it creates exactly the same full-text inverted index as created by previous approaches: a score for all the keywords in each peer  ...

A Flexible Extension of XQuery Full-Text

Emanuele Panzeri, Gabriella Pasi
2013 Italian Information Retrieval Workshop  
This paper presents the implementation of an extension of the XQuery Full-Text language on top of the BaseX query engine.  ...  BaseX has been chosen for being the first system (and the only one, to the best of our knowledge) to implement the full XQuery Full-Text language.  ...  The XQuery Full-Text extension in a nutshell For each element matched by the Below and Near, a score is computed by the approximate matching; the score is in the interval ]0, 1] where 1 represents a full  ...

Moving More Quickly toward Full Term Relations in Information Space

Gregory B. Newby
1999 Text Retrieval Conference  
The paper describes an implementation of a multidimensional tree structure for retrieval from information space based on the kd-tree.  ...  The AdHoc task emphasized query expansion, while the large Web track emphasized rapid indexing and retrieval.  ...  Introduction Efforts for the 8 th Text REtrieval Conference (TREC) included the following: 1. AdHoc task, fully automatic. 2. Small Web track 3.  ...

Supporting full-text information retrieval with a persistent object store [chapter]

Eric W. Brown, James P. Callan, W. Bruce Croft, J. Eliot B. Moss
1994 Lecture Notes in Computer Science  
The inverted file index common to many full-text information retrieval systems presents unusual and challenging data management requirements.  ...  Instead, we have used a persistent object store, Mneme, to support the inverted file of a full-text information retrieval system, INQUERY.  ...  Introduction The task of a full-text information retrieval (IR) system is to satisfy a user's information need by identifying the documents in a collection of documents that contain the desired information  ...
