Research Abstract

インターネットや携帯電話の発展の中で文章、音声、画像などのマルチメディアデータが爆発的に増大している。本研究では、人手介入なしに、計算機によってこれらを分類あるいは検索する方式を検討した。我々が過去検討してきた、圧縮率によるテキストの特徴表現方式を原理としつつ、より高性能な圧縮性特徴空間の構成可能性の検討、文書や画像分類への適用などを試みた。文法知識を事前準備せずに、文章や画像に適用できること、従来方式をしのぐ性能も発揮できることなどを確認できた。なお、EUでの衛星画像利用地球環境管理国際プロジェクト(GEOSS)関係機関より招待され、衛星画像処理への応用可能性について講演も実施した。
