結びつけると、何ができるのか?
「全文検索」「クロス表検索」「マップ検索」「時系列検索」「議員の特徴語」など
▶ 「クロス表検索」では
ü 時系列データと横断面データを用いて,キーワードの出現傾向を分析できる
▶ 「マップ検索」では
ü キーワードの出現回数を地図上に表示し,地域特有の言語表現(方言や課題など)を可視化できる
結びつけると「議員の特徴語」がわかる
lTFIDFで「議員の特徴語」をみつける
ü TFIDFは「(他の議員は発言していないけれど)ある議員だけがたくさん発言している特徴語をみつけることができる」
l形態素解析(単語分割)はComainu
▶ 例えば,「次に、プログラミング教育の実施についてであります。 」を形態素解析する
ü 形態素解析 MeCab NEologd
l 「次に 、 プログラミング 教育 の 実施 について で あり ます 。 」
ü 形態素解析 Comainu 長単位
l 「次 に 、 プログラミング教育 の 実施 について であり ます 。 」
