(オンライン学習の効果について)
上記の言語解析機の自動構築方法を用いて実験を行った。その実験結果を図39に示す。図39に示したグラフの横軸は経過時間(単位は日)であり、縦軸は平均F値(Average F−Measures)である。また、実線(Online,1k)及び破線(Online,4k)は、オンライン学習による学習用データセットの逐次更新を続けた場合の実験結果を示している。一方、鎖線(Offline,1k)及び一点鎖線(Offline,4k)は、オフライン学習による実験結果を示している。なお、1kは、推定機の構築に利用する学習用データの数を1000個に設定したことを示している。一方、4kは、推定機の構築に利用する学習用データの数を4000個に設定したことを示している。
(About the effects of online learning)
Experiments were conducted using the above-mentioned automatic construction method for language analyzers. The experimental results are shown in FIG. The horizontal axis of the graph shown in FIG. 39 is the elapsed time (the unit is days), and the vertical axis is the average F value (Average F-Measures). In addition, a solid line (Online, 1k) and a broken line (Online, 4k) indicate experimental results when the learning data set is continuously updated by online learning. On the other hand, a chain line ( Offline , 1k) and an alternate long and short dash line ( Offline , 4k) indicate the experimental results by offline learning. Note that 1k indicates that the number of learning data used to construct the estimator is set to 1000. On the other hand, 4k indicates that the number of learning data used to construct the estimator is set to 4000.
