Multilingual Summarization and Translingual Transmedia Information Retrieval
In the first topic, I will introduce a general architecture of a
multi-document summarization system at first. Several important issues
such as clustering algorithms, clustering units, features used in
clustering, and event detection will be discussed. Then I will show how
to extend the architecture to a multilingual multi-document
summarization system. Some extra issues like translation documents
among different languages, idiosyncrasy among languages, and user
preference will be touched on.
In the second topic, I will introduce this challenging research problem
at first. Then, several approaches to unify the languages and media of
queries and documents will be presented. Some preliminary results on
cross-language image retrieval via spoken query are shown.

Automatic Query Refinement for Mono- and Cross-Lingual Information
One of the important techniques for cross-lingual information retrieval
(CLIR) is translation disambiguation, of which purpose is to remove
automatically erroneous translation candidates obtained in the process
of dictionary-based translation of original query terms. Kishida and
Kando (2003) have proposed a "two-stage query refinement" technique for
the disambiguation, and empirically shown that it works well at the
retrieval experiment in CLEF-2003. The author would like to talk about
procedure and characteristics of the two-stage refinement. This
technique is also easy to be applied to monolingual retrieval situation.
For example, in Japanese monolingual retrieval, it is possible that
original query is expanded by conducting repeatedly Japanese-English and
English-Japanese translations as a pseudo cross-lingual retrieval. In
order to refine the expanded set of query terms, our "two-stage
refinement" technique would be available. A result of preliminary
experiments will be presented.
