Query structuring and expansion with two-stage term dependence for Japanese web retrieval

Koji Eguchi, W. Bruce Croft
2009 Information retrieval (Boston)  
The relevance model is constructed using the retrieval results of the structured query with term dependence to expand the query.  ...  Based on this assumption, our two-stage term dependence model captures both long-range and short-range term dependencies differently, when more than one compound word appear in a query.  ...  in part by the Center for Intelligent Information Retrieval.  ...

Document Structure Analysis in Associative Patent Retrieval

Atsushi Fujii, Tetsuya Ishikawa
2004 NTCIR Conference on Evaluation of Information Access Technologies  
Based on the rhetorical structure, a claim is segmented into multiple components, each of which is used to produce an initial query. The structure of an application is used to enhance each query.  ...  The main task was an associative patent retrieval task, in which a patent application including a target claim is used to search documents that can invalidate the demand in the claim.  ...  Acknowledgments The authors would like to thank Yuka Yamada for her support with experiments. They would also like to thank Akihiro Shinmori for his support with the RST tool.  ...

Combination Approaches in Korean Information Retrieval: Words vs. n-grams, and Query Translation vs. Document Translation

IN-SU KANG, SEUNG-HOON NA, JONG-HYEOK LEE
2006 International Journal of Computer Processing Of Languages  
For cross-language information retrieval, we attempt a dictionary-based bi-directional combination of query translation and document translation.  ...  Experimental evaluations on CJK monolingual and KC/KJ cross-language retrieval give promising results on our combination approaches: words vs. ngrams, and query translation vs. document translation.  ...  Acknowledgements This work was supported by the KOSEF through  ...

University of Chicago at NTCIR4 CLIR: Multi-Scale Query Expansion

Gina-Anne Levow
2004 NTCIR Conference on Evaluation of Information Access Technologies  
However, more detailed per-language analysis finds significantly better effectiveness in Japanese when character-bigram units are employed for the identification of presumed relevant documents during query  ...  We find that for the very short queries with many untranslatable words in this test collection, both pre-and post-translation query expansion, independently and in conjunction, significantly enhance retrieval  ...  Structured query formulation, using the "#syn" operator, treats the appearance of any of the translation alternatives as evidence for and as an instance of the source language term.  ...

Document Structure Analysis for the NTCIR-5 Patent Retrieval Task

Atsushi Fujii, Tetsuya Ishikawa
2005 NTCIR Conference on Evaluation of Information Access Technologies  
The structure of the application is used to enhance each query. The candidates of relevant documents are retrieved and ranked on a component-by-component basis.  ...  Our system is characterized by the structure analysis for both target claim and entire application. The target claim is segmented into components, each of which is used to produce an initial query.  ...  Second, we use the conventional pseudo-relevance feedback (PFR) to further enhance the query, which enhances a query with two-stage retrieval.  ...

Combining Active Learning and Partial Annotation for Domain Adaptation of a Japanese Dependency Parser

Daniel Flannery, Shinsuke Mori
2015 Proceedings of the 14th International Conference on Parsing Technologies  
We also show that entropy-based query selection strategies can be combined with partial annotation to annotate informative examples in the new domain without annotating full sentences.  ...  We evaluate query strategies based on both full and partial annotation in several domains, and find that they reduce the amount of in-domain training data needed for domain adaptation by up to 75% compared  ...  of The National Institute for Japanese Language and Linguistics.  ...

Using Syntactic Dependency and Language Model X-IOTA IR System for CLIPS Mono & Bilingual Experiments in CLEF 2005

Loïc Maisonnasse, Gilles Sérasset, Jean-Pierre Chevallet
2005 Conference and Labs of the Evaluation Forum  
This document describes the CLIPS experiments done for the CLEF 2005 campaign. We use surface-syntactic parser in order to extract new indexing terms. These terms are syntactic dependencies.  ...  We used them under different forms in different information retrieval models, particularly in a language model.  ...  In a second time the query is generated following the distribution P(Q|L,D), the query terms are generated at this stage according on the terms linked in L.  ...

Easing Erroneous Translations in Cross-Language Image Retrieval Using Word Associations [chapter]

Masashi Inoue
2006 Lecture Notes in Computer Science  
On the other hand, word association models help in retrieval for Japanese topics.  ...  Connecting short queries and short titles of relevant images is difficult. Different lexical expressions may be used in queries and captions that refer to the same concept.  ...  The above argument might be verified by comparing various languages with different degree of difficulties in English translation.  ...
