Luceneでローマ字変換

[改訂新版] Apache Solr入門 ~オープンソース全文検索エンジン (Software Design plus)

　[7.1.3 Suggester]で使用しているJapaneseReadingFormFilterを参考に。(というかまんま)

今回はeclipseにプラグインを入れてgradleプロジェクトとして作ってみました。
build.gradleはデフォルトで作成されるものにlucene用のdependenciesを追加。
不要なものも混ざってますがご容赦ください。

apply plugin: 'java'
apply plugin: 'eclipse'

sourceCompatibility = 1.6
targetCompatibility = 1.6
version = '1.0'
jar {
    manifest {
        attributes 'Implementation-Title': 'Gradle Quickstart', 'Implementation-Version': version
    }
}

repositories {
    mavenCentral()
}

dependencies {
    compile 'org.apache.lucene:lucene-core:4.7.2'
    compile 'org.apache.lucene:lucene-analyzers-common:4.7.2'
    compile 'org.apache.lucene:lucene-analyzers-kuromoji:4.7.2'
    testCompile 'junit:junit:4.+'
}

test {
    systemProperties 'property': 'value'
}

uploadArchives {
    repositories {
       flatDir {
           dirs 'repos'
       }
    }
}

そして、コード

package com.example;

import java.io.IOException;
import java.util.Arrays;
import java.util.List;

public class Romanize {

    public static void main(String[] args) {
        Analyzer analyzer = new JapaneseAnalyzer(Version.LUCENE_47);
        try {
            List<String> texts = Arrays
                    .asList("すもももももももものうち。", "メガネは顔の一部です。",

                            "Lucene is a full-featured text search engine library written in Java.");
            for (String text : texts) {
                TokenStream tokenStream = analyzer.tokenStream("", text);
                try {
                    romanize(tokenStream);
                } catch (IOException e) {
                    e.printStackTrace();
                } finally {
                    tokenStream.close();
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        } finally {

    }

    private static void romanize(TokenStream tokenStream) throws IOException {
        CharTermAttribute charTermAttr = tokenStream
                .addAttribute(CharTermAttribute.class);
        ReadingAttribute readingAttr = tokenStream
                .addAttribute(ReadingAttribute.class);
        tokenStream.reset();
        while (tokenStream.incrementToken()) {
            String token = charTermAttr.toString();
            String reading = readingAttr.getReading();
            String readingRoma = null;
            if (reading != null) {
                readingRoma = ToStringUtil.getRomanization(reading);
            } else if (isHalfWidthAlphanumeric(token)) {
                readingRoma = token;
            } else {
                readingRoma = ToStringUtil.getRomanization(token);
            }
            System.out.println("token:" + token + " ,reading:" + reading
                    + " ,readingRoma:" + readingRoma);
        }
    }

    private static boolean isHalfWidthAlphanumeric(String text) {
        if (text == null || text.length() == 0
                || text.length() != text.getBytes().length) {
            return false;
        }
        return true;
    }

}

Analyzerの使い方など参考にさせていただいたのはココ

JapaneseAnalyzerでトークン分割後に

String reading = readingAttr.getReading();

読みカナを取得し、

readingRoma = ToStringUtil.getRomanization(reading);

そして読み仮名をToStringUtil.getRomanizationに渡すとローマ字を得られます。

else if (isHalfWidthAlphanumeric(token)) {
    readingRoma = token;
}

半角アルファベットと数字はそのまま使用。

else {
    readingRoma = ToStringUtil.getRomanization(token);
}

それ以外の読み仮名が得られなかった単語はとりあえず元の単語をそのままローマ字変換してみましたf^^;

結果は以下となりました。

token:もも ,reading:モモ ,readingRoma:momo

MacにJDK6をインストール

java mac

職場の環境に合わせるためにJDK6を自宅のmacにインストールしようと思いまして。
早速oracleさんのサイトへ。

Java Archive Downloads - Java SE 6

ファッ！？

Mac用のインストーラがない・・だと・・？

教えてgoogle先生！

ってわけで、ありましたよ。
Appleが別途提供しているみたいです。

Java for OS X 2013-005

無事インストール出来ました〜
ただ、デフォルトインストール先がそれぞれで異なるようです。

/Library/Java/JavaVirtualMachines/
jdk1.7.0_25.jdk

S2JUnit4をmavenで実行する際の注意点

JUnit maven

仕事でJUnitを書いたのは１年目以来でしょうか。(現在８年目。。)
ちょっと時間に余裕ができたので久々に書いてみました。

テスト対象はパラメータで渡した値を条件にDBからレコードを取得するメソッド。

ってことで、↓を参考にExcelでテストデータを用意し自動読み込みするようにして、境界値テストとして取得できるケースとできないケースを計5ケースほど書きました。

Seasar - DI Container with AOP
S2Unit

ローカルでの実行は無事グリーンになり、意気揚々とコミットしてJenkinsさんからテスト環境へビルド/デプロイ＆テスト！

・・・

orz..
取得できるケースだけ失敗してるからテストデータが読み込めていない模様。
サンプルのようにテストケースクラスと同フォルダにデータも置いていたんですが、↓のサイトの通りでclasses側にデータがコピーされないせいみたいです。

Maven2でのリソースファイルの取り扱い

ってことで、/src/test/resources配下に置き換えて再挑戦したところ、うまくいきました。

ただ、/src/test/resources配下にズラーっと並ぶのが嫌だったので、s2junit4.diconを以下のようにしてテストケースクラス毎にフォルダを分けるようにしました。

<component class="org.seasar.framework.unit.impl.TestDataPreparerImpl">
    <initMethod name="addTestDataXlsPath">
        <arg>
            "data/" + context.testClassShortName + "/" + context.testMethodName + ".xls"
        </arg>
    </initMethod>
    <initMethod name="addTestDataXlsPath">
        <arg>
            "data/" + context.testClassShortName + "/common.xls"
        </arg>
    </initMethod>
</component>

ちなみに現在のカバレッジは0.8%・・レガシーです＼(^o^)／
目指せ1％！
