Machine Translation of Low-Resource Spoken Dialects: Strategies for Normalizing Swiss German
The goal of this work is to design a machine translation (MT) system for a
low-resource family of dialects, collectively known as Swiss German, which are
widely spoken in Switzerland but seldom written. We collected a significant
number of parallel written resources to start with, up to a total of about 60k
words. Moreover, we identified several other promising data sources for Swiss
German. Then, we designed and compared three strategies for normalizing Swiss
German input in order to address the regional diversity. We found that
character-based neural MT was the best solution for text normalization. In
combination with phrase-based statistical MT, our solution reached 36% BLEU
score when translating from the Bernese dialect. This value, however, decreases
as the testing data becomes more remote from the training one, geographically
and topically. These resources and normalization techniques are a first step
towards full MT of Swiss German dialects.Comment: 11th Language Resources and Evaluation Conference (LREC), 7-12 May

Automatic Construction of Clean Broad-Coverage Translation Lexicons
Word-level translational equivalences can be extracted from parallel texts by
surprisingly simple statistical techniques. However, these techniques are
easily fooled by {\em indirect associations} --- pairs of unrelated words whose
statistical properties resemble those of mutual translations. Indirect
associations pollute the resulting translation lexicons, drastically reducing
their precision. This paper presents an iterative lexicon cleaning method. On
each iteration, most of the remaining incorrect lexicon entries are filtered
out, without significant degradation in recall. This lexicon cleaning technique
can produce translation lexicons with recall and precision both exceeding 90\%,
as well as dictionary-sized translation lexicons that are over 99\% correct.Comment: PostScript file, 10 pages. To appear in Proceedings of AMTA-9
Cross-language Text Classification with Convolutional Neural Networks From Scratch
Cross language classification is an important task in multilingual learning, where documents in different languages often share the same set of categories. The main goal is to reduce the labeling cost of training classification model for each individual language. The novel approach by using Convolutional Neural Networks for multilingual language classification is proposed in this article. It learns representation of knowledge gained from languages. Moreover, current method works for new individual language, which was not used in training. The results of empirical study on large dataset of 21 languages demonstrate robustness and competitiveness of the presented approach
