java - 如何从BerkeleyAligner读取Alignment类型？ -Java

从http://code.google.com/p/berkeleyaligner/下载主干代码后，我将项目添加到Eclipse的构建路径中。然后，使用下面的代码，我可以提取从sourceFile和targetFile中读取的每个句子对的对齐方式。
对齐后，如何从BerkeleyAligner读取Alignment类型？

import edu.berkeley.nlp.wa.mt.Alignment;
import edu.berkeley.nlp.wa.mt.SentencePair;
import edu.berkeley.nlp.wordAlignment.combine.WordAlignerCombined;
public static void main(String[] args) {
BufferedReader brSrc = new BufferedReader(new FileReader ("sourceFile"));
BufferedReader brTrg = new BufferedReader(new FileReader ("targetFile"));
while ((currentSrcLine = brSrc.readLine()) !=null) {
    String currentTrgLine = brTrg.readline();
    // Reads into BerkeleyAligner SentencePair format.
    SentencePair src2trg = new SentencePair(sentCounter, params.get("source"),
        Arrays.asList(srcLine.split(" ")), Arrays.asList(trgLine.split(" ")));
    // Generate Alignment type from SentencePair
    WordAlignerCombined aligner;
    Alignment alignedPair = aligner.alignSentencePair(src2trg);
    // How do i print out the Alignment???
    }
}

例如源文件：

this is the first line in the textfile.
that is the second line.
foo bar likes to eat bar foo.

例如targetFile：

Dies ist die erste Textzeile in der Datei.
das ist die zweite Zeile.
foo bar gerne bar foo essen.

最佳答案

打印GIZA。 Alignment为此提供了一种方法：

public void writeGIZA(PrintWriter out, int idx)

GIZA是：

"# sentence pair (%d) source length %d target length %d alignment score : 0\n"
"NULL ({ %s })"
" %s ({ %s })" (englishSentence.get(i), StrUtils.join(alignments))

idx只是句子对ID。

out就是您要打印它的地方。
