Relational Data Model in Document Hierarchical Indexing [chapter]

Alexander Gelbukh, Grigori Sidorov, Adolfo Guzmán-Arenas
2002 Lecture Notes in Computer Science  
One of the problems of the development of document indexing and retrieval applications is the usage of hierarchies.  ...  In this paper we describe a method of automatic hierarchical indexing using the traditional relational data model.  ...  These problems can be resolved if we apply automatic indexing of documents using a concept dictionary that usually has a form of a hierarchy of concepts (concept tree), see, for example, [4] .  ...

FlexIR: a Domain-Specific Information Retrieval System

Saïd Radhouani, Claire-Lise Mottaz Jiang, Gilles Falquet
2009 POLIBITS Research Journal on Computer Science and Computer Engineering With Applications  
The dimensions, as described below, are made of concepts and semantic relationships that represent a particular perspective or point of view on the domain.  ...  We mainly use the notion of domain dimension to: i) precisely index document content, and ii) develop an interactive interface which allows the user to precisely describe his or her information need and  ...  Thus, during the conceptual indexing, all documents dealing with this concept will be represented by the identifier "C0630058".  ...

Concept-based readability measurement and adjustment for web services descriptions

Pananya Sripairojthikoon, Twittie Senivongse
2014 16th International Conference on Advanced Communication Technology  
Given a WSDL document as a service description, readability is defined in terms of the use of difficult words in the description and the use of words that are key concepts in the service domain.  ...  Since WSDL documents are the primary source of service information, readability of WSDL documents is of concern to service providers, i.e., service descriptions should be understood with ease by service  ...  depth(c i ) = depth of domain concept c i in the WSDL document d i , with regard to the concept hierarchy.  ...

A hierarchical monothetic document clustering algorithm for summarization and browsing search results

Krishna Kummamuru, Rohit Lotlikar, Shourya Roy, Karan Singal, Raghu Krishnapuram
2004 Proceedings of the 13th conference on World Wide Web - WWW '04  
Evaluating the quality of a topic hierarchy is a non-trivial task, the ultimate test being user judgment.  ...  In this paper, we propose a new hierarchical monothetic clustering algorithm to build a topic hierarchy for a collection of search results retrieved in response to a query.  ...  Each node in the hierarchy is associated with a concept (i.e., the node label) and all documents under that node contain that concept.  ...

Classifying Biomedical Text Abstracts Based On Hierarchical 'Concept' Structure

Rozilawati Binti Dollah, Masaki Aono
2011 Zenodo  
In this paper, we present an approach for classifying a collection of biomedical text abstracts downloaded from Medline database with the help of ontology alignment.  ...  Subsequently, we compute the cosine similarity between the vector in probable concepts (in the "enriched" OHSUMED disease hierarchy) and the vector in Medline abstract disease hierarchies.  ...  Enrichment had been done by mapping each concept or node in the OHSUMED disease hierarchy with a set of related features that extracted and selected from the OHSUMED dataset.  ...

Sense-Based Biomedical Indexing and Retrieval [chapter]

Duy Dinh, Lynda Tamine
2010 Lecture Notes in Computer Science  
We propose and evaluate two methods of Word Sense Disambiguation (WSD) for biomedical terms and integrate them to a sense-based document indexing and retrieval framework.  ...  Ambiguous biomedical terms in documents and queries are disambiguated using the Medical Subject Headings (MeSH) thesaurus and semantically indexed with their associated correct sense.  ...  Hence, each concept in the document (query) is tagged with the appropriate sense in the local context and indexed with its unique sense in the document.  ...

Exploiting hierarchical relationships in conceptual search

Devanand Ravindran, Susan Gauch
2004 Proceedings of the Thirteenth ACM conference on Information and knowledge management - CIKM '04  
This is the goal of KeyConcept, a conceptual search engine. During indexing, KeyConcept classifies documents into concepts selected from a manuallyconstructed concept hierarchy.  ...  To provide the user with more useful information, we need a system that disambiguates queries by including information about the user's conceptual framework.  ...  Documents are indexed by their keywords and by concepts automatically selected from the Open Directory [ODP] concept hierarchy.  ...

The efficiency of inverted index and cluster searches

Ellen M. Voorhees
1986 Proceedings of the 9th annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '86  
The efficiency of each search is measured in two ways: the number of bytes required to store the auxiliary files required by the search, and the mean time required to retrieve a set of documents for a  ...  Recent research by the author corroborates these findings and also shows that the partial ranking produced by a topdown search of the complete link hierarchy can be more effective than ranking the collection  ...  This enhancement is not possible with the inverted index search since the terms of a document are usually spread throughout the index.  ...
