Extracting Multilingual Topics from Unaligned Comparable Corpora [chapter]

Jagadeesh Jagarlamudi, Hal Daumé
2010 Lecture Notes in Computer Science  
In this paper we present a generative model called JointLDA which uses a bilingual dictionary to mine multilingual topics from an unaligned corpus.  ...  Though there are some attempts to mine topical structure from cross-lingual corpora, they require clues about document alignments.  ...  Extracting Multilingual Topics from Unaligned Comparable Corpora  ...

Qualitative Comparison of Native and Machine-Translated Parliamentary Debates

Ajda Pretnar Zagar
2022 Digital Humanities in the Nordic Countries Conference  
It qualitatively compares three steps in topic interpretation: topic description, topic significance in subcorpora, and marginal topic distribution.  ...  They can potentially lift the barriers to applying NLP tools and methods to previously unsupported languages and boost comparative cross-lingual research in digital humanities.  ...  PTM can be extended to unaligned documents, but not all corpora contain comparable documents.  ...

Pseudo-Aligned Multilingual Corpora

Fernando Diaz, Donald Metzler
2007 International Joint Conference on Artificial Intelligence  
We apply semisupervised methods to pseudo-align multilingual corpora. Specifically, we construct a topicbased graph for each language.  ...  Experimental results show that pseudo-alignment of multilingual corpora is feasible and that the document alignments produced are qualitatively sound.  ...  This would allow one to leverage topic information from different languages when defining the lower-dimensional topic space. Second, we adopted parallel corpora for evaluation reasons.  ...

Cross-Lingual Latent Topic Extraction

Duo Zhang, Qiaozhu Mei, ChengXiang Zhai
2010 Annual Meeting of the Association for Computational Linguistics  
Both qualitative and quantitative experimental results show that the PCLSA model can effectively extract cross-lingual latent topics from multilingual text data.  ...  Probabilistic latent topic models have recently enjoyed much success in extracting and analyzing latent topics in text in an unsupervised way.  ...  Besides all the multilingual topic modeling work discussed above, comparable corpora have also been studied extensively (e.g.  ...

Neural Machine Translation for Low Resource Languages using Bilingual Lexicon Induced from Comparable Corpora

Sree Harsha Ramesh, Krishna Prasad Sankaranarayanan
2018 Proceedings of the 2018 Conference of the North American Chapter of the Association for Computational Linguistics: Student Research Workshop  
Resources for the non-English languages are scarce and this paper addresses this problem in the context of machine translation, by automatically extracting parallel sentence pairs from the multilingual  ...  In this paper, we have used an end-to-end Siamese bidirectional recurrent neural network to generate parallel sentences from comparable multilingual articles in Wikipedia.  ...  Comparable corpora such as Wikipedia, are collections of topic-aligned but non-sentence-aligned multilingual documents which are rich resources for extracting parallel sentences from.  ...

Harvesting Comparable Corpora and Mining Them for Equivalent Bilingual Sentences Using Statistical Classification and Analogy-Based Heuristics [chapter]

Krzysztof Wołk, Emilia Rejmund, Krzysztof Marasek
2015 Lecture Notes in Computer Science  
This research explores our new methodologies for mining such data from previously obtained comparable corpora.  ...  Here we propose a web crawling method for building subject-aligned comparable corpora from e.g. Wikipedia dumps and Euronews web page.  ...  We seek to obtain parallel corpora from unaligned data. Solution proposed by our team is based on sequential analogy detection.  ...

Adversarial Alignment of Multilingual Models for Extracting Temporal Expressions from Text [article]

Lukas Lange, Anastasiia Iurshina, Heike Adel, Jannik Strötgen
2020 arXiv   pre-print
In this paper, we explore multilingual methods for the extraction of temporal expressions from text and investigate adversarial training for aligning embedding spaces to one common space.  ...  With this, we create a single multilingual model that can also be transferred to unseen languages and set the new state of the art in those cross-lingual transfer experiments.  ...  Introduction The extraction of temporal expressions from text is an important processing step for many applications, such as topic detection and questions answering (Strötgen and Gertz, 2016) .  ...

Controlling Target Features in Neural Machine Translation via Prefix Constraints

Shunsuke Takeno, Masaaki Nagata, Kazuhide Yamamoto
2017 Workshop on Asian Translation  
Prefix constraints can be predicted from source sentence jointly with target sentence, while side constraints must be provided by the user or predicted by some other methods.  ...  prefix constraints are more flexible than side constraints and can be used to control the behavior of neural machine translation, in terms of output length, bidirectional decoding, domain adaptation, and unaligned  ...  Tatoeba is a collection of multilingual translated example sentences from Tatoeba website.  ...
