少し前に、私は自分の Web サイトのコンテンツ フィルターに関してかなり長い質問をしました。投稿はこちらにありますので、ご自由にお読みください。

@DampeS8N の回答を受け入れました。彼はよく答えて、正しい方向に私を送ってくれたからです。

残念ながら、上記の質問の結果は、私が使用しているコンテンツ フィルターは、私のアプリケーションのコンテキストで実行するにはあまりにも効率が悪いというものでした。

情報は次のとおりです。

  • 2000 以上の用語集* と 1200 以上の種のプロファイル** があります。
  • これらの投稿のタイトル (用語集エントリ) または学名 (種のプロファイル) は、フィルターの検索用語を構成します。
  • 上記の検索用語を検索し、関連する用語集のエントリまたは種のプロファイルへのリンクに置き換えるために、種のプロファイルの内容をフィルタリングしたいと思います (できれば保存時に、しかし cron ジョブで行うこともできます)。

*用語集のエントリはここにあります。

用語集エントリのリストの例は、、、、caudal finなどdorsalです filter

**種のプロファイルはここにあります。

種のリストの例はApistogramma panduro、 、A. panduroDario dario、などD. darioです。Betta sp. 'Maha Chai'

問題は次のとおりです。

  • 私の CMS は WordPress によって駆動されています。これは、私の種プロファイルの構造を理解することを除けば、この投稿には特に関係ありません。
  • 私の種のプロファイルは、テーブルに保存されているいくつかの基本情報と、wp_postsテーブルに保存されている追加情報で構成されていwp_postmetaます。
  • 私の種プロファイルのほとんどの情報は、テーブルmeta fieldsへのエントリであるいくつかの に保存されていwp_postmetaます。これは以下で見ることができます。

メンテナンス
タンクは、浮かぶ植物も使用してよく植える必要があります。このは日中に隠れることを好むので、たくさんの隠れ場所を提供する必要があります。埋もれ木、岩の洞窟、PVCパイプはすべてこの目的に適しています。とげのあるウナギはしばしば自分自身を埋めることを好むので、砂は基質として使用されるべきです。調光照明は、魚が隠れ場所からより頻繁に冒険することを奨励します。ウナギは最小の隙間を通り抜けることができるので、ぴったりと合うフードが必要です。魚は主に野生の静水の領域に生息しているため、水の流れはかなり穏やかでなければなりません。

以下は、wp_glossaryのエントリの例です。

出力プロファイル

上記のデータベース構造を維持できたら、wp_relationでwp_postmetaのエントリのIDを検索することにより、各wp_postmetaの用語集リンクを簡単に作成できます。次に、を使用str_replaceしてコンテンツへのリンクを埋めます。

パフォーマンスを向上させるために、結果のコンテンツをHTMLでキャッシュできます。キャッシュの有効期限を1日または2日に設定します(用語集とサイトトラフィックを更新する頻度によって異なります)。memcachedfileまたはを使用databaseしてキャッシュを保存できます。


データベース構造の維持

最も難しい作業は、データベースの関係を維持することです。データベースの関係を変更する2つの主要なアクションがあります。

用語集の変更

  • 新しい用語集の追加: wp_postmetaを検索し、関係を構築します。
  • 用語集の削除:この用語集と他のwp_postmetaの間のすべての関係を削除します
  • 用語集の編集:用語集の削除と新しい用語集の追加を組み合わせたものです。

Postmetaを変更する

  • Postmetaの追加/編集:用語集とその内容の関係を再構築します。以下は、関係を構築するために使用できるアルゴリズムです。私はそれを行うための他のより良い方法があると信じています。コードは完全ではありませんが(まだテストしていません)、アルゴリズムを理解するには十分です。

    // Initialize text to add glossary link
    $desc = "Tank should be well planted with floating plants also used. 
            An abundance of hiding places should be provided as this species 
            likes to hide away during the day. Bogwood, rock caves and PVC 
            piping are all suitable for this purpose. Sand should be used as 
            substrate as the spiny eels often like to bury themselves. 
            Dimmer lighting will encourage the fish to venture from 
            its hiding places more often. A close-fitting hood is required 
            as the eel can find its way through the smallest of gaps. Water 
            flow should be fairly gentle as the fish mainly inhabits 
            areas of still water in the wild.";
    
    // Split text into list of words
    $split = preg_split("/[.,\s]+/", $desc);
    
    // Frequency English words
    $freq['will'] = true;
    $freq['also'] = true;
    $freq['with'] = true;
    $freq['about'] = true;
    $freq['back'] = true;
    $freq['been'] = true;
    $freq['were'] = true;
    $freq['want'] = true;
    
    // Get list of unqiue word and elimate unnessary words
    foreach($split as $value) {
        $value = strtolower($value);
    
        if (strlen($value) < 4) continue;
        if (is_numeric($value)) continue;
        if (isset($freq[$value])) continue;
    
        if (!isset($hash[$value])) $hash[$value] = true;
    }
    
    // Join the list for search
    $keys = "";
    foreach ($hash as $key => $value)
        $keys .= "^{$key}|";
    $keys = rtrim($keys, '|');
    
    // Search for list of glossary
    $glossary;
    $result = mysql_query("SELECT glossary_id,glossary_key FROM wp_glossary  WHERE gossary_key REGEXP '{$keys}'")
    if ($result) {
        while($row = mysql_fetch_row($result)) {
            if (strpos($desc, $row[1]) !== false)
                $glossary[$row[0]] = $row[1];
        }
    }
    
    // You can start to construct the relation from this $glossary
    // by loop throught it one by one and insert it into wp_relation
    print_r($glossary);
    
  • Postmetaの削除:このpostmetaと用語集の間の関係を削除します。


追加のメリット

用語集「埋もれ木」を使用する種のプロファイルを見つけるとしましょう。wp_relationを介して簡単に追跡できます。


質問

1。まず、str_replaceは、既存のコード、つまりhrefまたはimgコードを含む種のプロファイルにどのように影響しますか?

a link用語集と種名がない場合は、種のプロファイルには影響しません。

2。次に、用語集のエントリについて言及しましたが、少し複雑な種の属/種名については言及していません。それらに別のテーブルを使用しますか、それともすべてを1つに組み込みますか?

種名とpostmetaの関係を格納するための個別のテーブルを作成することも、種名を特別なフラグ付きの用語集用語として扱うこともできます(用語集の構造を変更する必要があります)。

3。次に、用語集のエントリと種のプロファイルの違い(タグ内の異なるクラス)をどのように指定しますか?

回答は、2番目の質問に使用する方法によって異なります。

三分探索木を考えたことはありますか?

これは、「テキスト質量 y から x 個の単語を見つける」という問題に直面したときに私が好むデータ構造です。

構築されたツリーの例 (fin、filter、caudal、gal、gaudy):

        f
       /|\
caudal* i ga
        |  | 
        n* l*
       /    \
    lter*    udy*

* = end node

アルゴリズムは次のようになります。

  • ルート ノードで一致する単語を開始します。
  • 現在の位置が一致する限り、下に移動します。
  • 現在の位置 < ノードの場合。左に移動します。
  • 現在の位置 > ノードの場合。右に動く。
  • 単語が終了し、ノードが終了ノードの場合。単語が見つかりました。
  • 左右に移動できない場合、または単語が非終了ノードで終了している場合。単語が見つかりません。

これが良い例です。

利点は、ツリーを事前に計算して、シリアル化された形式で保存できることです。多くの場合、事前に構築されたツリーを構築またはクライアントに転送し、ブラウザーでマッチングを行うことさえ可能です。
