Analysis of the dnaB gene, homologue of the Escherichia replicative DNA helicase DnaB, from various Mycobacterium intracellulare complex strains revealed their dnaB genes were heterogeneity. We found...

Inherited Feature-based Similarity Measure Based on Large Semantic Hierarchy and Large Text Corpus (2002)

Hideki Hirakawa, Zhonghui Xu, Kenneth Haase

Wc describe a similarity calculation model called IFSM (Inherited Feature Similarity Measure) between objects (words/concepts) based ou their men and distinctive features. We propose an...

Machine Translation vs. Dictionary Term Translation (2002)

Nigel Collier, Hideki Hirakawa, Akira Kumano

Bilingual news article alignment methods based on multi-lingual information retrieval have been shown to be successful for the automatic production of so-called noisy-parallel corpora. In this paper...

An Experiment in Hybrid Dictionary (2002)

Nigel Collier, Kenji Ono, Hideki Hirakawa

The task of aligning sentences in parallel corpora of two languages has been well studied using pure statistical or linguistic models. We developed a linguistic method based on lexical matching with...

Cross Language Information Retrieval: an Experimentin Bilingual News Article Alignment from the Internet using MT (2000)

Nigel Collier, Hideki Hirakawa, Akira Kumano

Cross Language Information Retrieval (CLIR) offers the potential for users to search document collections in foreign languages. This is particularly relevant now that the Internet has become a global...

Automatic Refinement of a POS Tagger Using a Reliable Parser and Plain Text Corpora (2000)

Hideki Hirakawa, Kenji Ono, Yumiko Yoshimura

This paper proposes a new unsupervised learning method for obtaining English part-ofspeech (POS) disambiguation rules which would improve the accuracy of a POS tagger. This method has been...

Creating a Noisy Parallel Corpus from Newswire Articles Using Cross-Language Information Retrieval (1998)

Nigel Collier, Hideki Hirakawa, Akira Kumano

this paper we present an adaptation of cross-language information retrieval for the production of an aligned bilingual corpus from noisy-parallel English-Japanese newswire articles. We implement the...
