Lexical cohesion and term proximity in document ranking

Olga Vechtomova, Murat Karamuftuoglu
2008 Information Processing & Management  
Two types of lexical cohesive relationship information between query terms are used in document ranking: short-distance collocation relationship between query terms, and long-distance relationship, determined  ...  We demonstrate effective new methods of document ranking based on lexical cohesive relationships between query terms.  ...  The paper describes in detail how lexical cohesion between query terms in documents could be used in document ranking, and points to the potential of the cohesion theory in improving effectiveness of retrieval  ...

A graph based approach to estimating lexical cohesion

Hayrettin Gürkök, Murat Karamuftuoglu, Markus Schaal
2008 Proceedings of the second international symposium on Information interaction in context - IIiX '08  
In this paper we make use of a graph-based approach to capture term contexts and estimate the level of lexical cohesion in a document.  ...  Lexical cohesion is a characteristic of natural language texts, which can be used to determine whether the query terms are used in the same context in the document.  ...  CONCLUSION AND FUTURE WORK We have investigated different methods for document ranking based on lexical cohesion among query terms in a document.  ...

On document relevance and lexical cohesion between query terms

Olga Vechtomova, Murat Karamuftuoglu, Stephen E. Robertson
2006 Information Processing & Management  
A document ranking method based on lexical cohesion shows some performance improvements.  ...  Lexical cohesion between distinct query terms in a document is estimated on the basis of the lexical-semantic relations (repetition, synonymy, hyponymy and sibling) that exist between there collocates  ...  Ranking of a document set by lexical cohesion scores results in significant performance improvement over term-based document ranking techniques.  ...

Query expansion with terms selected using lexical cohesion analysis of documents

Olga Vechtomova, Murat Karamuftuoglu
2007 Information Processing & Management  
We present new methods of query expansion using terms that form lexical cohesive links between the contexts of distinct query terms in documents (i.e., words surrounding the query terms in text).  ...  The link-forming terms (link-terms) and short snippets of text surrounding them are evaluated in both interactive and automatic query expansion (QE).  ...  Acknowledgements We would like to thank Susan Jones (City University, London) and anonymous referees for their valuable comments and suggestions.  ...

Lexical cohesion for evaluation of machine translation at document level

Billy T.M. Wong, Cecilia F.K. Pun, Chunyu Kit, Jonathan J. Webster
2011 2011 7th International Conference on Natural Language Processing and Knowledge Engineering  
While most state-of-the-art evaluation metrics focus on the sentence level, we emphasize the importance of document structure, showing that lexical cohesion is a critical feature to highlight the superior  ...  An experiment shows that this feature can bring forth a 3-5% improvement in the correlation of automatic evaluation results with human judgments of machine translation outputs at the document level.  ...  The research described in this paper was partially supported by City University of Hong Kong through the SRG grants 7002267 and 7008003 and by the Research Grants Council (RGC) of HKSAR, China, through  ...

An effective coherence measure to determine topical consistency in user-generated content

Jiyin He, Wouter Weerkamp, Martha Larson, Maarten de Rijke
2009 International Journal on Document Analysis and Recognition  
The properties that make the coherence score more appropriate than lexical cohesion, a common measure of topical structure, are discussed.  ...  The coherence score must, however, be used judiciously in order to avoid boosting the ranking of irrelevant but topically focused blogs.  ...  Open Access This article is distributed under the terms of the Creative Commons Attribution Noncommercial License which permits any noncommercial use, distribution, and reproduction in any medium, provided  ...

A study of the effect of term proximity on query expansion

Olga Vechtomova, Ying Wang
2006 Journal of information science  
Query expansion terms are often used to enhance original query formulations in document retrieval.  ...  Such terms are usually selected from the entire documents or from windows or passages surrounding query term occurrences.  ...  Term proximity has been explored extensively in document ranking studies [16] [17] [18] [19] [20] , where several distance factors were proposed.  ...

Intra-content term weighting for topic segmentation

Abdessalam Bouchekif, Geraldine Damnati, Delphine Charlet
2014 2014 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)  
This paper deals with term weighting strategies in the context of lexical cohesion based topic segmentation.  ...  It translates the capacity of a term to discriminate a document within a collection, or a part of a document within a whole document.  ...  Lexical cues borrowed from traditional text segmentation. Main lexical approaches include the notions of lexical cohesion introduced in [1] and lexical chaining [2] , [3] , [4] .  ...

Extracting Clusters of Specialist Terms from Unstructured Text

Aaron Gerow
2014 Proceedings of the 2014 Conference on Empirical Methods in Natural Language Processing (EMNLP)  
Term clusters are identified by extracting communities in the cooccurrence graph, after which the largest is discarded and the remaining words are ranked by centrality within a community.  ...  Automatically identifying related specialist terms is a difficult and important task required to understand the lexical structure of language.  ...  Duede and three reviewers for comments on earlier versions of this manuscript.  ...

Extracting Informative Content Units in Text Documents

Reischer Jürgen
2020 Zenodo  
The notion of semantic and thematic informativeness of text is explored in theory and practice.  ...  Possible applications for semantic text processing including conceptual indexing and passage extraction are presented and discussed.  ...  The user wants informative documents, not just relevant ones.
