英语和巴斯克语的决策列表

Decision Lists for English and Basque

Eneko Agirre, David Martinez

摘要:

在本文中,我们描述了我们开发的英语(词汇和所有单词)和巴斯克语的任务系统。它们都是基于Yarowsky决策列表的监督系统。我们使用Semcor进行英语全词任务的训练。我们为每种语言定义了不同的功能集。对于巴斯克语,为了从文本中提取所有信息,我们使用形态分析仪定义了以前文献中未使用过的特征。我们还实现了自动选择良好特征的系统,并能够以覆盖率为代价获得前缀精度(85%)。使用所有功能的系统被标识为BCU-ehu-dlist-all,选择某些功能的系统被标识为BCU-ehu-dlist-best。

英文摘要:

In this paper we describe the systems we developed for the English (lexical and all-words) and Basque tasks. They were all supervised systems based on Yarowsky's Decision Lists. We used Semcor for training in the English all-words task. We defined different feature sets for each language. For Basque, in order to extract all the information from the text, we defined features that have not been used before in the literature, using a morphological analyzer. We also implemented systems that selected automatically good features and were able to obtain a prefixed precision (85%) at the cost of coverage. The systems that used all the features were identified as BCU-ehu-dlist-all and the systems that selected some features as BCU-ehu-dlist-best.
