Tokyo Stock Exchange, Inc. (TSE) is launching Proof of Concept (PoC) testing for limited public distribution of corpus data created from timely disclosure documents and others. Corpus is an accumulation of digitized natural language sentences utilized for research on natural language processing, etc. and in recent years, employed especially for machine translation.
