A Cross-media Retrieval System for Lecture Videos
Atsushi Fujii, Katunobu Itou, Tomoyosi Akiba +1
We propose a cross-media lecture-on-demand system, in which users can selectively view specific segments of lecture videos by submitting text queries. Users can easily formulate qu…
Building a Test Collection for Speech-Driven Web Retrieval
Atsushi Fujii, Katunobu Itou
This paper describes a test collection (benchmark data) for retrieval systems driven by spoken queries. This collection was produced in the subtask of the NTCIR-3 Web retrieval tas…
Speech-Driven Text Retrieval: Using Target IR Collections for Statistical Language Model Adaptation in Speech Recognition
Atsushi Fujii, Katunobu Itou, Tetsuya Ishikawa
Speech recognition has of late become a practical technology for real world applications. Aiming at speech-driven text retrieval, which facilitates retrieving information with spok…
Language Modeling for Multi-Domain Speech-Driven Text Retrieval
Katunobu Itou, Atsushi Fujii, Tetsuya Ishikawa
We report experimental results associated with speech-driven text retrieval, which facilitates retrieving information in multiple domains with spoken queries. Since users speak con…
A Method for Open-Vocabulary Speech-Driven Text Retrieval
Atsushi Fujii, Katunobu Itou, Tetsuya Ishikawa
While recent retrieval techniques do not limit the number of index terms, out-of-vocabulary (OOV) words are crucial in speech recognition. Aiming at retrieving information with spo…
