title: GALE Arabic-English Word Alignment Training Part 1 -- Newswire and Web

description: <h3>Introduction</h3><br>
<p>GALE Arabic-English Word Alignment Training Part 1 -- Newswire and Web was developed by the Linguistic Data Consortium (LDC) and contains 344,680 tokens of word aligned Arabic and English parallel text enriched with linguistic tags. This material was used as training data in the <a href="https://www.ldc.upenn.edu/collaborations/past-projects" rel="nofollow">DARPA GALE</a> (Global Autonomous Language Exploitation) program.</p><br>
<p>Some approaches to statistical machine translation include the incorporation of linguistic knowledge in word aligned text as a means to improve automatic word alignment and machine translation quality. This is accomplished with two annotation schemes: alignment and tagging. Alignment identifies minimum translation units and translation relations by using minimum-match and attachment annotation approaches. A set of word tags and alignment link tags are designed in the tagging scheme to describe these translation units and relations. Tagging adds contextual, syntactic and language-specific features to the alignment annotation.</p><br>

<p>Note that word count is based on the untokenized Arabic source, and token count is based on the tokenized Arabic source.</p><br>
<p>The Arabic word alignment tasks consisted of the following components:</p><br>
<ul><br>
<li>Normalizing tokenized tokens as needed</li><br>
<li>Identifying different types of links</li><br>
<li>Identifying sentence segments not suitable for annotation</li><br>
<li>Tagging unmatched words attached to other words or phrases</li><br>
</ul><br>
