http://io9.com/5901579/10-tricks-that-c​​hatbots-use-to-make-you-believe-theyre-human

ルール：

1. 任意のプログラミング言語を使用できます。
2. プログラムは、ファイル名、ネットワーク、またはユーザー入力以外の入力を受け付けません。
3. 事前に設定されたボキャブラリーは存在できません。ボットはユーザー入力から知っているすべてのことを学習する必要があり、議論は何でも可能です。

必須の基準：

1. これはCode-golfではありませんが、シンプルにしてください。ソースコードのサイズはプログラミング言語に対応する必要があります。つまり、GolfScript = short、BF = long、other =常識を使用します。サンプルコードを参照として使用すると、コードはそのサイズの2倍になる可能性がありますが、その後は適切です。
2. プログラムは、最初の1000文内で遅れることはありません（5〜10秒の遅延）。
3. 合理的な議論は、約20〜30文以内で行う必要があります。
4. アルゴリズムは、ロジックが可能な限りサンプルコードと異なる必要があります。

オプションのボーナス審査基準：

1. より良いボット学習アルゴリズム、より良いプログラム。
2. テニスの試合はありません。つまり、会話は「ユーザー>コンピューター>ユーザー」という厳密なループターンに従いません。
3. 模倣は少なく、ボットの動作はユーザーの行動とは異なり、ユーザーの態度からボットの態度の認識を分離します。
4. たとえば、おしゃべり、静寂、楽観、悲観など、さまざまな変化する気分を感知します。
5. 「ブレイン」を保存およびロードする方法。これにより、ボットと別の日に議論を続けることができます。

Java

新しい編集：空き時間でさらに調整します。DFSアルゴリズムで遊んでいる新しいブランチを開始しました。公式には、ブランチは私が計画している新しいBFSアルゴリズムの中核として機能することですが、それまでは、DFSが何をしているか、どのように意思決定を行っているかをより良く把握したかったのです。そのため、文章が長くなるにつれてトピックの有無に関係なく、新しい単語の値を減衰させ始める抑制機能を追加しました。同様に、すべての単語は現在、文に価値をもたらしていますが、トピックまたは文のトピックリストに含まれていない単語は、頻度値のわずか25％を占めています。会話の例はここにあり、物理学、Chatbrainsの人間性、およびその他の魅力的なトピックについて話しています。ブランチコードはこちら。

編集：私は少しコードを微調整してきました。ここにリビジョンを投稿する代わりに、最新のリビジョンが見つかるgithubリポジトリでチェックしてください。また、最新バージョンに対して新しい会話を追加しました。チャットボット、深さ優先検索、およびプログラミングを使用して生物を構築する方法について説明します。

私はこの課題を総合的に受け入れることにしました。私のチャットボットは、言葉も、構文も、何もないという非常に少ないことを知っています。標準の英語を単語に解析する方法、および単語以外の文字を句読点として識別する方法を知っています。それでおしまい。ユーザーとのやり取りから学んだことをすべて知っています。やり取りする際、単語間のつながりに注意を払い、その情報を使用して文章を構築します。もちろん、詳細についてはソースを参照してください。私はこの課題の推奨されるプログラムの長さを大きく超えましたが、それは良い目的です。プログラムのハイライトは次のとおりです。

• Chatbotは知識なしで開始します（「ルール」：3に続きます）
• 単語の出現頻度が追跡されます
• 単語の頻度は「減衰」しているため、会話はトピック間で移動できます（「ボーナス」：3および4に従います）。
• 観察された文の単語の配列が記録されるため、「フレーズ」は暗黙的に追跡されます（たとえば、ボットとチャットするときに多くの前置詞フレーズを使用すると、ボットも多く使用します！）
• 文は、単語間で最も頻繁に観察される接続を追跡することを好み、変化を注入するためのランダムな要素を使用して構築されます
• 文構築アルゴリズムは深さ優先検索であり、出力文でのトピックワードの出現を最大化しようとしますが、文の終了は少し優先されます（これは「ボーナス」に続きます-私はかなりクールな学習アルゴリズムを使用しています。時間の経過とともに変化し、収集された単語接続の知識を保持します）
  • 編集：トピックの単語は、再発する単語のグローバルな知識と最新の文の両方から描画されるようになりました
  • 編集：単語の重みは単語の長さの対数4を使用して計算されるようになったため、長い単語はより強く重み付けされ、短い単語はより弱くなります-これは、重み付けと使用の両方で使用する真のコーパスの不足を補うためですコーパスで簡単にできるように、高頻度で価値の低い単語を排除します。
  • 編集：構築中に文の長さが長くなると、抑制機能が追加の単語の値を減らし始めます。
  • 編集：文の「終了」は、短い愚かな文の圧倒的多数を引き起こしていたので、今ではあまり価値がありません。
  • 編集：トピック外の単語はグローバルな頻度値の25％でのみ寄与しますが、すべての単語が値に寄与します。
  • 組み込みの深さの最大値があり、文を構築するために先例の単語を使用しているためにループが多くなり、時間がかかりすぎない
  • ループは文の構築中に直接検出され、技術的には許可されていますが、ループが回避される可能性が高くなります
  • 調整可能なタイムアウトは、ブランチのプルーニングとステートメントのファイナライズの両方を促進し、ルールで5〜10秒の「許容可能な遅延」を超えないようにするために使用されます

ルールへの接続を要約するには：

• 「ルール」：1、私はとても優しくなり、冗長であるJavaの、選びました。
• 「ルール」：2私は将来のために、脳のセーブ/ロードを追加するために、いくつかのスタブコードを持っているが、単独のユーザ入力が、活用されます
• 「ルール」：3、何の事前設定語彙は絶対にありません。ChatBotは英語の解析方法を知っていますが、それだけです。初めは、まったく何も知りません。
• 「必須条件」：1、私のプログラムは長いですが、素晴らしいの多くをパック。お見逃しなく。
• 「必須条件」：2、私は明示的に私の文章構成アルゴリズムのタイムアウトを持っている以上の5-6秒の時間を検索防ぎます。これまでの最良の文はタイムアウト時に返されます。
• 「必須条件」：3ボットは、その後で上のトピックとなりますので、トピックは、一般的に、約10の文章で凝固し、20の文章で実際に意味のビットを作るいくつかの魅力的なランダムな構築物で声明への応答されます。
• 「必須条件」：4、私は、参照コードから何を借りていません。これは完全にユニークな構造です。
• 以下のために「ボーナス」：1、私はこのボットはかなり異例だと思いたいです。スクリプト化されたボットほど説得力はありませんが、トピックに関する制限はまったくなく、会話のトピックからトピックへと（永続的に）優雅に移動します。
• 以下のための2：「ボーナス」、これは厳密にラウンドロビンであるので、ここでノーボーナス。まだ。応答にはアルゴリズム内に要件はないため、このボーナスに対処するスレッドバージョンを計画しています。
• 「ボーナス」：3、最初にこのボットは模倣しますが、最初のいくつかの文章を越えて会話進行すると、まねることは明確に終了します。
• 以下のために「ボーナス」：4、「気分」は、任意の意味のある方法で処理されていないが、次のボットの好みのトピックとして、それは気分をシフトします。
• 「ボーナス」：5、保存と読み込み脳は場所で、現在ではありません。

そのため、すべての基本ルール、すべての必須ルール、暫定的なボーナスルール1、3、および4を満たしました。

別のボーナスとして、コード全体にコメントしましたので、お気軽に借りたり、改善のための提案を行ってください。明らかに、組み込みの対話や「構造」知識がないため、会話は他のボットよりも長い間奇妙になりますが、私は規則をかなり満たしていると思います。

次に、コード（ボディの制限に合うように編集されたコメントもあります）またはGitHubでフォローします。

ディスカッションを開始するにはしばらく時間がかかります。しばらくすると、ディスカッションは次のようになります。

 Mindless:   Why would I run? I am not scared of you.
      YOU:   Who are you and why do you keep asking stupid questions?

 Mindless:   I never said that you should run.
      YOU:   I never said I will run.

 Mindless:   I am the hidden, who are you?
      YOU:   I am god.

 Mindless:   I will
      YOU:   You will obey me.

 Mindless:   Why would I run? I am not scared of you.
      YOU:   You should be scared of me.

 Mindless:   I never said I will run.
      YOU:   Who said you will run?

 Mindless:   Who are you and why do you keep asking stupid questions?
      YOU:   I will not anymore.

 Mindless:   I never said that you should run.
      YOU:   I never said I will run.

 Mindless:   I am the hidden, who are you?
      YOU:   I can see you!

 Mindless:   Why would I run? I am not scared of you.
      YOU:   I am hunting you down

 Mindless:   You should be scared of me.
      YOU:   That is a lie.

 Mindless:   What can't you do?
      YOU:   Why can't I do what?

 Mindless:   You don't.
      YOU:   Well, you are talking nonsense.

 Mindless:   How do I take it seriously.
      YOU:   Stop talking to me

 Mindless:   Well, I can hide, but you can't.
      YOU:   This is not a funny conversation.

 Mindless:   Yes, I will. Stay on line.
      YOU:   Do you want to eat somewhere?

 Mindless:   I laugh
      YOU:   Are you laughing at me?

 Mindless:   Yes, you do.
      YOU:   Can I join you laghs?

 Mindless:   I can hide, but you can't.
      YOU:   Why would you hide? I asked if you want to eat?

 Mindless:   Well, I can see you!
      YOU:   Yes, and I see you. eat something maybe?

 Mindless:   I will not anymore.
      YOU:   Have you stopped eating?

 Mindless:   I never said I will run.
      YOU:   Well, I was talking about eating. Is dinner a good thing to do?

 Mindless:   I take it seriously.
      YOU:   Okay, take it seriously and follow me to the restaurant and get some food to eat.

 Mindless:   Have you stopped eating?
      YOU:   NO absolutely not! A am starving because of YOU who refuse to eat

 Mindless:   I never said I will run.
      YOU:   Well, we can walk to the restaurant instead.

 Mindless:   Well, I was talking about eating. Is dinner a good thing to do?
      YOU:   Yes, that is perfect. What are the best fried chickens around here?

 Mindless:   I laugh
      YOU:   You laugh at the chicken?

 Mindless:   Are you laughing at me?
      YOU:   No, I am eating. Chicken.

 Mindless:   You are a thinker?

 Mindless:   You can try run, but you can't hide
      YOU:   I will run.

 Mindless:   I am hunting you down
      YOU:   Ha ha. Make sure you look at the restaurant first. I might be there eating.

 Mindless:   I never said I will run.
      YOU:   Okay, but when you get there, I may still be there eating. I feel like I can eat a ton.

 Mindless:   That is a lie.
      YOU:   No, it is true.

 Mindless:   Why can't I do what?
      YOU:   You can eat a ton too, if you ever get there. And if you have the money.

 Mindless:   I never said I will run.
      YOU:   Okej, suit yourself.

 Mindless:   That is a lie.
      YOU:   God

 Mindless:   You laugh at the chicken?

 Mindless:   Stop talking to me
      YOU:   Okay, now you are really rude.

 Mindless:   This is not a funny conversation.
      YOU:   Okay, think about it. Try tell me something new.

 Mindless:   Stay. On course. To the restaurant!
      YOU:   Sure! I am already there staying on course eating the food.

 Mindless:   You can eat a ton too, if you ever get there. And if you have the money.
      YOU:   I have already paid for my food, and I will not share it with you.

Python3 + SQLite3

これが私が作った小さなボットです！

どのように機能しますか？

3つのSQLテーブルが使用されます。1つは単語用、1つは文用、1つはユーザーが入力した単語を、ボットが表示する次の文に関連付けるためのものです。

• 学習：ユーザーが書いた文は保存され、ダイアログの前の行でボットが使用した単語と句読点に関連付けられます。指定された行の単語の重要度に応じて、重みが適用されます。
• 取得：文は取得され、各文は、ユーザーが最後の行で使用した単語とデータベース内の文に関連付けられた単語との相関関係に応じたスコアを持ちます。
• トーキング：最高スコアの文章が出力に送信されます。前のユーザーの単語に関連付けられた文がない場合、ランダムな文が送信されます。

特別な機能は何ですか？

• 繰り返しすぎない：ボットは、まだ言っていないことを出力することを望みます。
• 高速実行：一意のインデックスを使用したデータベース駆動型
• 速い学習： 10行のダイアログ内でほぼ意味のあることを言い始めます。
• 脳の保存/読み込み：データベースが削除されない限り、ボットの状態が保持されます。
• 長い単語は短い単語よりも意味にとって重要です
• 句読点数
