Rebecca Bilbro con Applied Text Analysis With Python: Enabling Language-aware Data Products With Machine Learning

From news and speeches to informal chatter on social media, natural language is one of the richest and most underutilized sources of data. Not only does it come in a constant stream, always changing and adapting in context; it also contains information that is not conveyed by traditional data sources. The key to unlocking natural language is through the creative application of text analytics. This practical book presents a data scientist’s approach to building language-aware products with applied machine learning.You’ll learn robust, repeatable, and scalable techniques for text analysis with Python, including contextual and linguistic feature engineering, vectorization, classification, topic modeling, entity resolution, graph analysis, and visual steering. By the end of the book, you’ll be equipped with practical methods to solve any number of complex real-world problems.Preprocess and vectorize text into high-dimensional feature representationsPerform document classification and topic modelingSteer the model selection process with visual diagnosticsExtract key phrases, named entities, and graph structures to reason about data in textBuild a dialog framework to enable chatbots and language-driven interactionUse Spark to scale processing power and neural networks to scale model complexityApplied Text Analysis With Python: Enabling Language-aware Data Products With Machine Learning A pesar del avance en la concienciación de la ciudadanía con respecto al medio ambiente, es imprescindibleseguir en la brecha para modificar las actitudes de las personas. En este sentido, la escuela tiene también laoportunidad de contribuir a esta concienciación ciudadana. En las páginas de este libro el lector encontraráreflexiones y propuestas interesantes y novedosas (para infantil, primaria y secundaria), que demuestran quees posible e imprescindible trabajar en y desde la escuela por un desarrollo sostenible de la Tierra.
