| Research Abstract |
We have obtained the following results concerning GDA (Global Data Annotation) standardization, applications and peripheral technologies.
(1) GDA annotation of Mainichi Newspaper articles: 200 articles of Mainichi Newspaper of the past 10 years are manually annotated with GDA tags including anaphora and co-references.
(2) Proposal of GDA concepts to MPEG-7 Standardization: The proposal or Linguistic Description Scheme based on GDA and UNL (Universal Network Language) has been adopted as MPEG-7 Second version Working Draft.. In addition, it is under negotiation by ISO/TC37/SC4 Language Resource Management Standardization. A simple automatic transformation from GDA to UNL enables to translate a simple GDA-annotated. Japanese sentence into English, Italian, Spanish and Arabian automatically.
(3) MPEG-7 annotation for music: Vie pointed out the problems of.ontology alignment that is well-known to AI community, and generated automatically a musical instrument ontology by which known and unknown musical instruments are identified with a high recognition performance.,
(4) Automatic speaker indexing of minutes of round table: For round tables with alternative speakers, automatic speaker indexing has been developed with multi-speaker models obtained by training with a very large dialogue corpus, domain knowledge obtained by a very large minutes corpus of the Lower House. Thus, its performance is quite high.
(5) Privacy-enhanced access control: Although security draws much attention, privacy is never-the-less important for accessing various corpora. For this purpose, we designed a privacy-enhanced access control based on the SPKI (Simple Public Key Infrastructure) and demonstrated its feasibility by implementing a Web server.
