Recurrent Neural Network-based Language Models with Variation in Net Topology, Language, and Granularity

Tzu-Hsuan Yang
Tzu-Hsuan Tseng

In this paper, we study language models based on recurrent neural networks on three databases in two languages. We implement basic recurrent neural networks (RNN) and refined RNNs with long short-term memory (LSTM) cells. We use the corpora of Penn Tree Bank (PTB) and AMI in English, and the Academia Sinica Balanced Corpus (ASBC) in Chinese. On ASBC, we investigate wordbased and character-based language models. For characterbased language models, we look into the cases where the inter-word space is treated or not treated as a token.

Verifying the Long-range Dependency of RNN Language Models

Tzu-Hsuan Tseng
Tzu-Hsuan Yang

It has been argued that recurrent neural network language models are better in capturing long-range dependency than n-gram language models. In this paper, we attempt to verify this claim by investigating the prediction accuracy and the perplexity of these language models as a function of word position, i.e., the position of a word in a sentence. It is expected that as word position increases, the advantage of using recurrent neural network language models over n-gram language models will become more and more evident.

History Question Classification and Representation for Chinese Gaokao

Ke Yu

In this paper, we propose a question representation based on entity labeling and question classification for a automatic question answering system of Chinese Gaokao history question. A CRF model is used for the entity labeling and SVM/CNN/LSTM models are tested for question classification. Our experiments show that CRF model provides a high performance when used to label informative entities out while neural networks has a promising performance for the question classification task.

The Effect of Shallow Segmentation for English-Tigrinya Statistical Machine Translation

Kazuhide Yamamoto

This paper presents initial English-Tigrinya statistical machine translation (SMT) research. Tigrinya is a highly inflected Semitic language spoken in Eritrea and Ethiopia. Translation involving morphologically complex languages is challenged by factors including data sparseness and source-target word alignment. We try to address these problems through morphological segmentation of Tigrinya words. After segmentation the difference in token count dropped significantly from 37.7% to 0.1%. The out-of-vocabulary rate was reduced by 46%.

Word Sense Implantation as Orthographical Conversion

Kazuhide Yamamoto

We present a word sense disambiguation (WSD) tool of Japanese Hiragana words. Unlike other WSD tasks which output something like “sense #3” as result, our WSD task rewrites the target word into a Kanji word, which is a different orthography. This means that the task is also a kind of orthographical normalization as well as WSD. In this paper we present the task, our method, and the performance.

Annotation Schemes for Constructing Uyghur Named Entity Relation Corpus

Kahaerjiang Abiderexiti

Uyghur is minority language in China, it is one of the official languages in Xinjiang Uyghur Autonomous Region of China. More than 10 million people use Uyghur in their daily life and even on the Internet. However, lack of Uyghur entity relation corpus constrains relation extraction applications in Uyghur. In this paper, we describe annotation schemes for creating annotated corpus for Uyghur named entity and Uyghur named entity relation.

Japanese Orthographical Normalization Does Not Work for Statistical Machine Translation

Kazuhide Yamamoto
Kanji Takahashi

We have investigated the effect of normalizing Japanese orthographical variants into a uniform orthography on statistical machine translation (SMT) between Japanese and English. In Japanese, 10% of words have reportedly more than one orthographical variants, which is a promising fact for improving translation quality when we normalize these orthographical variants.

Fundamental Tools and Resource are Available for Vietnamese Analysis

Kanji Takahashi
Kazuhide Yamamoto

This paper presents our work on developing Vietnamese fundamental tools and a resource for analysis. These tools are for word segmentation and part-of-speech tagging, diacritics restoration, and orthographical variants dictionary. All of them have been either not publicly available so far or not attaining sufficient performance. We have developed the tools and released the tools to the public, in both software packages and web tools. For development, we utilize state-of-the-art methods and achieved high accuracy.
