Extracting Multilingual Topics from Unaligned Comparable Corpora
[chapter]
2010
Lecture Notes in Computer Science
Preserved Fulltext
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. ...

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. ...

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) . ...
