内容简介
如果您想构建使用自然语言文本的企业级应用程序，但不确定从哪里开始或使用什么工具，那么本实用指南将帮助您入门。Wisecube的首席数据科学家Alex Thomas向软件工程师和数据科学家展示了如何使用深度学习和Apache Spark NLP库构建可扩展的自然语言处理(NLP)应用程序。通过具体的例子、实践和理论解释，以及在Spark processing框架上使用NLP的动手练习，这本书教你从基本语言学和写作系统到情绪分析和搜索引擎的一切。您还将探讨开发基于文本的应用程序的一些特殊问题，比如性能。
作者简介
亚历克斯·托马斯是Wisecube的首席数据科学家。他将自然语言处理和机器学习运用于临床数据、身份数据、雇主和求职者数据以及如今的生化数据。Alex从09版本开始使用Apache Spark，在工作中也用过包括UIMA和OpenNLP在内的多种NLP库和框架。
