FaDA: Fast Document Aligner using Word Embedding

FaDA1 is a free/open-source tool for aligning multilingual documents. It employs a novel crosslingual information retrieval (CLIR)-based document-alignment algorithm involving the distances between embedded word vectors in combination with the word overlap between the source-language and the target-language documents. In this approach, we initially construct a pseudo-query from a source-language document. We then represent the target-language documents and the pseudo-query as word vectors to find the average similarity measure between them. Thisword vector-based similaritymeasure is then combinedwith the termoverlap-based similarity. Our initial experiments show that s standard Statistical Machine Translation (SMT)based approach is outperformed by our CLIR-based approach in finding the correct alignment pairs. In addition to this, subsequent experiments with the word vector-based method show further improvements in the performance of the system.
