中文简介: | 概率上下文自由语法 (pcfg) 是一种强大的形式主义, 已被用于计算语言学的多种应用。这些模型的一个重要问题是模型概率部分的概率估计。这种概率估计是基于类似于 cky 算法的表格算法。我们回顾了这些估计算法及其性质。还介绍了这些模型在语言建模和机器翻译中的应用。最后, 阐述了一种用于分析的交互预测框架, 该框架可用于开发在线学习技术和主动学习技术。 |
课程简介: | Probabilistic Context Free Grammars (PCFG) is a powerful formalism that has been used for several applications in Computational Linguistics. One important problem of these models is the probabilistic estimation of the probabilistic part of the models. This probabilistic estimation is based on tabular algorithms similar to the CKY algorithm. We review these estimation algorithms and their properties. The use of these models for Language Modeling and Machine Translation is also introduced. Finally, an interactive-predictive framework for parsing is explained, that can be used for developing both on-line learning techniques and active learning techniques. |
