Chinese text retrieval without using a dictionary
1997
Proceedings of the 20th annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '97
Preserved Fulltext
It is generafly believed that words, rather than characters, should be the smallest indexing unit for Chinese text retrieval systems, and that it is essential to have a comprehensive Chinese dictionary ...
Chinese text has no delimiters to mark woni boundaries. As a result, any text retrieval systems that build word-based indexes need to segment text into words. ...
Acknowledgments A portion of this work was supported by grant NSF IRI-9630765 from the Database and Expert Systems program of the Computer and Information Science and Engineering Directorate of the National ...

The method can be applied to both Chinese-English and English-Chinese CLIR, correctly extracting translations of OOV terms from the Web automatically, and thus is a significant improvement on earlier work ...
We use a method that extends earlier work in this area by augmenting this with statistical analysis, and corpus-based translation disambiguation to dynamically discover translations of OOV terms. ...
In our first run we used the given Chinese queries without any of the Chinese equivalents of the English OOV terms (C-C), and used this to compare the performance of the translated English queries without ...

On Chinese monolingual retrieval, we investigated the use of different entities as indexes and implement our retrieval system based on the Lucene toolkit. ...
On English-Chinese CLIR, we adopt query translation as the dominant strategy, and utilize English-Chinese bilingual dictionary as the important knowledge resource to acquire correct translations. ...
Dictionary-based approach is a popular word-based approach for text segmentation. In this approach, segmented texts are matched against a dictionary prior to being indexed. ...

This paper proposes and describes a process for generating an automatic Chinese thesaurus that can be used to provide related terms to a user's queries to enhance retrieval effectiveness. ...
In the absence of existing automatic Chinese thesauri, techniques used in English thesaurus generation have been evaluated and adapted to generate a Chinese equivalent. ...
This segmentation process will be used for all Chinese text processing related fields such as machine translation, natural language processing and information retrieval. ...

Several new techniques to improve the translation of out of vocabulary terms in English-Chinese cross-language information retrieval have been developed. ...
Our first approach was to collect English text from the Web and exclude all terms that can be found in a translation dictionary. ...
