摘要:

词性标注在自然语言处理中起着重要的作用。它可以应用于许多自然语言处理任务,如命名实体识别、句法分析、依存句法分析和文本组块。在本文中进行的调查,我们利用两个广泛使用的工具包,ClearNLP和斯坦福POS标签的技术,以及开发两个新的POS标记越南语,然后将它们与三个著名的越南语标签,即JVnTagger,vnTagger和RDRPOSTagger。我们做了一个系统的比较,以找出具有最佳性能的标记器。我们还设计了一个新的功能集来衡量统计标记器的性能。我们从Stanford Tagger和ClearNLP构建的新标记器具有新的功能集,可以在标记准确性方面胜过所有其他越南标记器。此外,我们还分析了一些特征对统计标记器性能的影响。最后,实验结果还表明,基于转换的标签,RDRPOSTagger,可以运行速度显着快于任何其他统计标签。

英文摘要:

Part-of-speech (POS) tagging plays an important role in Natural Language Processing (NLP). Its applications can be found in many NLP tasks such as named entity recognition, syntactic parsing, dependency parsing and text chunking. In the investigation conducted in this paper, we utilize the technologies of two widely-used toolkits, ClearNLP and Stanford POS Tagger, as well as develop two new POS taggers for Vietnamese, then compare them to three well-known Vietnamese taggers, namely JVnTagger, vnTagger and RDRPOSTagger. We make a systematic comparison to find out the tagger having the best performance. We also design a new feature set to measure the performance of the statistical taggers. Our new taggers built from Stanford Tagger and ClearNLP with the new feature set can outperform all other current Vietnamese taggers in term of tagging accuracy. Moreover, we also analyze the affection of some features to the performance of statistical taggers. Lastly, the experimental results also reveal that the transformation-based tagger, RDRPOSTagger, can run significantly faster than any other statistical tagger.
