次に、図6のフローチャートを参照して、習慣性操作クラスタリング処理について説明する。
ここで、図7を参照して、習慣性操作クラスタの比較と統合について説明する。
以上においては、習慣性操作クラスタ候補と、登録済みの習慣性操作クラスタとの、それぞれの操作の比較において、前操作と後操作が異なる操作が2つ存在し、それぞれの操作に対して可変範囲が設定される場合について説明してきた。
以上においては、習慣性操作に基づいた習慣性操作クラスタリング処理について説明してきたが、習慣性操作クラスタが生成された後、習慣性操作が変化することで、習慣性操作クラスタに削除、および追加、並びにEntityの変更等が、様々な変更が必要になることがある。
次に、対話クラスタを生成するための処理を説明するために、図9のフローチャートを参照して、対話クラスタリング処理について説明する。
次に、図10を参照して、操作種別(Intent)が同一で属性(Entity)が異なる操作について説明する。尚、以降において、操作種別、および属性については、それぞれ単にIntentおよびEntityとも称する。
次に、図11のフローチャートを参照して、Intentが同一でEntityが異なる操作判定処理について説明する。尚、図11のフローチャートにおけるIntentが同一でEntityが異なる操作判定処理は、図9のフローチャートにおけるステップS62の処理である。
次に、図12を参照して、Intentが同一でEntityが異なる操作に対する対話生成事例について説明する。
次に、図13のフローチャートを参照して、Intentが同一でEntityが異なる操作に対する対話処理について説明する。
(追加された操作)
次に、図14を参照して、追加された操作について説明する。
次に、図15を参照して、削除された操作について説明する。
次に、図16のフローチャートを参照して、追加および削除された操作判定処理について説明する。尚、図16のフローチャートにおける追加および削除された操作判定処理は、図9のフローチャートにおけるステップS64の処理である。
次に、図17を参照して、追加された操作および削除された操作に対する対話生成事例について説明する。
次に、図18のフローチャートを参照して、追加および削除された操作に対する対話処理について説明する。
次に、図19を参照して、観測コンテキストに依存する操作について説明する。
次に、図20のフローチャートを参照して、観測コンテキスト依存操作判定処理について説明する。尚、図20のフローチャートにおける観測コンテキスト依存操作判定処理は、図9のフローチャートにおけるステップS56の処理である。
次に、図21のフローチャートを参照して、対話クラスタ候補のコンテキスト情報更新処理について説明する。尚、図21のフローチャートにおける対話クラスタ候補のコンテキスト情報更新処理は、図9のフローチャートにおけるステップS72の処理である。
次に、図22を参照して、観測コンテキスト依存操作に対する対話生成事例について説明する。
次に、図23のフローチャートを参照して、観測コンテキスト依存操作に対する対話処理について説明する。
以上においては、依存コンテキスト種別Dcが、location(位置情報)である場合の例について説明してきたが、それ以外であってもよく、例えば、依存コンテキスト種別Dcがdialog(対話)に設定されるようにしてもよい。
依存コンテキスト種別Dcは、バイタル系のコンテキスト情報であってもよい。
依存コンテキスト種別Dcには、周囲の人物の属性を示すattributeが設定されるようにしてもよい。
依存コンテキスト種別Dcは、ユーザ間のネットワークを介したオンライン/オフライン状態等にして、例えば、観測コンテキスト情報Coであるオンライン/オフラインに応じて、オンライン状態のユーザはメッセージをすぐに受信して読むことができるものとみなし、オフライン状態のユーザはメッセージをすぐに読むことができないものとみなすようにしてもよい。
習慣性操作クラスタからなるマクロが実行される前/後の操作の修正/追加に対しても対話フラグを設定させるようにしてもよい。
スマートスピーカ等のような機器を介して連携することで家電機器のコントロール機能を使用して、習慣性操作クラスタからなるマクロ内の特定の操作がコンテキスト依存で実行できずエラーが発生してしまうような場合には、エラーの要因となる依存コンテキスト種別Dcを変化させられるものであれば問い合わせ発話なしで変化させることで、エラーの発生を抑制しつつマクロを実行するようにしてもよい。
また、図9のフローチャートを参照して説明した対話クラスタリング処理により特定の操作に対して異種および複数の対話フラグが設定され、特定の操作を実行する際に複数回の発話による問い合わせが行われることも想定される。
ところで、上述した一連の処理は、ハードウェアにより実行させることもできるが、ソフトウェアにより実行させることもできる。一連の処理をソフトウェアにより実行させる場合には、そのソフトウェアを構成するプログラムが、専用のハードウェアに組み込まれているコンピュータ、または、各種のプログラムをインストールすることで、各種の機能を実行することが可能な、例えば汎用のコンピュータなどに、記録媒体からインストールされる。
