A probabilistic model to exploit user expectations in XML information retrieval

Fouad Dahak, Mohand Boughanem, Amar Balla
2017 Information Processing & Management  
The main objective of this paper is to exploit a new source of evidence derived from the document hierarchical structure for XML information retrieval.  ...  We consider that the structure of XML document is an important source of prior knowledge, and the structural features of an element may influence the user to consider that element as relevant.  ...  Collection and metrics INEX (The Initiative for the Evaluation of XML retrieval) provides a benchmark for the evaluation of XML information retrieval.  ...

The XML Query Execution Engine (XEE) [chapter]

Dieter Scheffner, Johann-Christoph Freytag
2002 Databases and Information Systems II  
The characteristics of XML documents require new ways of storing and querying such documents.  ...  XEE provides a testbed for our Access Support Tree and TextArray data structure of which the basic idea is to separate the (logical) structure of a document from its "visible" text content.  ...  As for the mapping of query languages, the integration of both the concept of database query languages and the concept of information retrieval data plays an important role in the framework of XEE.  ...

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  ...  We also provide adapted index structures and operators for approximate query sequential data in a heterogeneous collection of XML documents.  ...  We postulate a 'yet' acceptable match: a perfect match for the XML elements, and no match for the attributes: GC mid (p i D , p R ) = C subst *(min(length(p i D ), length( p R ) . (7) That is: the paths  ...

A new indexing strategy for XML keyword search

Yongqing Xiang, Zhihong Deng, Hang Yu, Sijing Wang, Ning Gao
2010 2010 Seventh International Conference on Fuzzy Systems and Knowledge Discovery  
At present, there are two normal ways of retrieving XML documents. One is structure-based retrieval; the other is keyword-based retrieval.  ...  With the rapid increase of XML documents on the web, how to index, store and retrieve these documents has become a very popular and valuable problem.  ...  LAF table is very important here, because it stores the structure information of the XML tree. Table 1 is an example of LAF table for the XML tree in table (simple for LAF table).  ...
