• Authors: Stein{\th}\'or Steingr\'imsson, Hrafn Loftsson, Andy Way
• Abstract summary: SentAlign is an accurate sentence alignment tool designed to handle very large parallel document pairs. The alignment algorithm evaluates all possible alignment paths in fairly large documents of thousands of sentences and uses a divide-and-conquer approach to align documents containing tens of thousands of sentences.

• Abstract: We present SentAlign, an accurate sentence alignment tool designed to handle very large parallel document pairs. Given user-defined parameters, the alignment algorithm evaluates all possible alignment paths in fairly large documents of thousands of sentences and uses a divide-and-conquer approach to align documents containing tens of thousands of sentences. The scoring function is based on LaBSE bilingual sentence representations. SentAlign outperforms five other sentence alignment tools when evaluated on two different evaluation sets, German-French and English-Icelandic, and on a downstream machine translation task.

  Recent studies have shown that post-aligning multilingual pretrained language models (mPLMs) using alignment objectives can improve crosslingual alignment. This paper attempts to explicitly evaluate the crosslingual alignment and identify the key elements in transliteration-based approaches that contribute to better performance.

  We propose a framework for parallel corpus mining, which provides a quick and effective way to mine a parallel corpus from publicly available lectures on Coursera. For both English--Japanese and English--Chinese lecture translations, we extracted parallel corpora of approximately 50,000 lines and created development and test sets. This study also suggests guidelines for gathering and cleaning corpora, mining parallel sentences, cleaning noise in the mined data, and creating high-quality evaluation splits.

  We propose a dual-alignment pre-training (DAP) framework for cross-lingual sentence embedding. We introduce a novel representation translation learning (RTL) task, where the model learns to use one-side contextualized token representation to reconstruct its translation counterpart. Our approach can significantly improve sentence embedding.

  "Extract and Generate" (EAG) is a two-step approach to construct large-scale and high-quality multi-way aligned corpus from bilingual data. We first extract candidate aligned examples by pairing the bilingual examples from different language pairs with highly similar source or target sentences. We then generate the final aligned examples from the candidates with a well-trained generation model.

  We propose using Optimal Transport (OT) as an alignment objective during fine-tuning to improve multilingual contextualized representations. This approach does not require word-alignment pairs prior to fine-tuning and instead learns the word alignments within context in an unsupervised manner.

  Word alignment over parallel corpora has a wide variety of applications, including learning translation lexicons, cross-lingual transfer of language processing tools, and automatic evaluation or analysis of translation outputs. Recently, other work has demonstrated that pre-trained contextualized word embeddings derived from multilingually trained language models (LMs) prove an attractive alternative, achieving competitive results on the word alignment task even in the absence of explicit training on parallel data. In this paper, we examine methods to marry the two approaches: leveraging pre-trained LMs but fine-tuning them on parallel text with objectives designed to improve alignment quality, and proposing

• Massively Multilingual Document Alignment with Cross-lingual Sentence-Mover's Distance [8.395430195053061]
  Document alignment aims to identify pairs of documents in two distinct languages that are of comparable content or translations of each other. We develop an unsupervised scoring function that leverages cross-lingual sentence embeddings to compute the semantic distance between documents in different languages. These semantic distances are then used to guide a document alignment algorithm to properly pair cross-lingual web documents across a variety of low, mid, and high-resource language pairs.
