Using Dempster-Shafer Theory In Xml Information Retrieval

F. Raja, M. Rahgozar, F. Oroumchian
2008 Zenodo  
We present this weighting model for information retrieval systems that utilize plausible inferences to infer the relevance of elements in XML documents.  ...  In this paper, we describe an XML information retrieval weighting scheme that tries to find the most relevant elements in XML documents in response to a user query.  ...  In contrast, in XML Information Retrieval (XML IR) systems each document is considered as a text document with additional structural markups.  ...

Using small XML elements to support relevance

Georgina Ramirez, Thijs Westerveld, Arjen P. de Vries
2006 Proceedings of the 29th annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '06  
Small XML elements are often estimated relevant by the retrieval model but they are not desirable retrieval units.  ...  This paper presents a generic model that exploits the information obtained from small elements.  ...  INTRODUCTION In an XML retrieval setting each of the elements of an XML document, ranging from elements with only few terms (such as titles) to elements with thousands of terms (such as articles) could  ...

Aggregated Feature Retrieval for MPEG-7 [chapter]

Jiamin Ye, Alan F. Smeaton
2003 Lecture Notes in Computer Science  
A brief survey of current XML indexing techniques shows that an IR-based retrieval method provides a better foundation for retrieval as it satisfies important retrieval criteria such as content ranking  ...  An aggregation technique for XML document retrieval is adapted to an MPEG-7 indexing structure by assigning semantic meanings to various audio/visual features and this is presented here.  ...  The methods can be classified into three categories: • Information retrieval based indexing brings the structure of documents together with the content into one unified model.  ...

Logic-Based XML Information Retrieval for Determining the Best Element to Retrieve [chapter]

Maryam Karimzadegan, Jafar Habibi, Farhad Oroumchian
2005 Lecture Notes in Computer Science  
This paper presents UOWD-Sharif team's approach for XML information retrieval. This approach is an extension of PLIR which is an experimental knowledge-based information retrieval system.  ...  This system like PLIR utilizes plausible inferences to first infer the relevance of sentences in XML documents and then propagates the relevance to the other textual units in the document tree.  ...  Because the focal elements are singleton, then the belief function equates to the mass function.  ...

A comparison of two approaches to utilizing XML in parametric databases for temporal data

Seo-Young Noh, Shashi K. Gadia
2006 Information and Software Technology  
There are two approaches to implementing parametric databases using XML: 1) a native XML database with XQuery engine, and 2) an XML storage with a temporal query language.  ...  To determine which approach is appropriate in parametric databases, we consider four questions: the effectiveness of XML in modeling temporal data, the applicability of XML query languages, the userfriendliness  ...  When adapting XML in parametric data model, we could consider two approaches such as native XML database with XQuery engine and XML storage technology with a temporal query language.  ...

Web mining model and its applications for information gathering

Yuefeng Li, Ning Zhong
2004 Knowledge-Based Systems  
In the paper, we propose an abstract Web mining model for extracting approximate concepts hidden in user profiles on the semantic Web.  ...  The abstract Web mining model represents knowledge on user profiles by using an ontology which consists of both "part-of" and "is-a" relations.  ...  In this paper, the ontology in the abstract Web mining model consists of both "part-of" relation and "is-a" relation. We also discuss belief functions on such ontologies.  ...
