一篇非常有用的自然场景下文本识别的论文,源代码是用C++写的

An explosion of Web-based language techniques, merging of distinct fields, availability of phone-based dialogue systems, and much more make this an exciting time in speech and language processing. The first of its kind to thoroughly cover language technology – at all levels and with all modern technologies – this book takes an empirical approach to the subject, based on applying statistical and other machine-learning algorithms to large corporations. KEY TOPICS: Builds each chapter around one or more worked examples demonstrating the main idea of the chapter, using the examples to illustrate the relative strengths and weaknesses of various approaches. Adds coverage of statistical sequence labeling, information extraction, question answering and summarization, advanced topics in speech recognition, speech synthesis. Revises coverage of language modeling, formal grammars, statistical parsing, machine translation, and dialog processing. MARKET: A useful reference for professionals in any of the areas of speech and language processing.

Natural Language Processing with Python自然语言处理中文版。作为一个自然语言处理的初学者，看书看到“训练模型”，这模型那模型的，一直不知 道模型究竟是什么东西。看了这本书，从预处理数据到提取特征集，训练模型，测试修改等， 一步一步实际操作了之后，才对模型一词有了直观的认识（算法的中间结果，存储在计算机 中的一个个 pkl 文件，测试的时候直接用，前面计算过的就省了）。以后听人谈“模型”的 时候也有了底气。当然，模型还有很多其他含义。还有动词的“配价”、各种搭配、客观逻 辑对根据文法生成的句子的约束如何实现？不上机动手做做，很难真正领悟。 自然语言处理理论书籍很多，讲实际操作的不多，能讲的这么系统的更少。从这个角度 讲，本书是目前世界上最好的自然语言处理实践教程。初学者若在看过理论之后能精读本书， 必定会有获益。这也是翻译本书的目的之一。
