Text Analytics with Python Text analytics is all about obtaining relevant and useful information from some unstructured data. Text analytics techniques can be of great importance and can provide amazing help for various organizations that aim to derive some potentially valuable business insights from an amazingly large collection of text-based content like social media streams, emails or word documents. Sure, text analytics using natural language processing, machine learning, and statistical modeling can be very challenging since human language is commonly inconsistent. It contains various ambiguities mainly caused by inconsistent semantics and syntax. Fortunately, text analytics software can easily help you by transposing phrases and words contained in unstructured data into some numerical values that you later link with structured data contained in data set. It is more than apparent that major enterprises are increasingly and rapidly turning to text analytics techniques in order to improve their businesses as well as overall customer satisfaction. We are witnessing that amazing variety and volume when it comes to data generated across different feedback channels which continues to grow and expand providing various businesses with a wealth of valuable information regarding their customers. It is more than apparent that sifting through all available content would be amazingly time-consuming to be done manually. However, understanding those insights held in data is more than critical when it comes to getting an accurate view of the customer's voice. We are also witnessing the next chapter of text analytics approach since it's already developing that solid ground. It will also continue to be among other technical necessities today and into the future. In order to keep up with the future, embark on your own text analytics journey having this book by your side as your best companion. In this book ou will learn: Text analytics process How to build a corpus and analyze sentiment Named entity extraction with Groningen meaning bank corpus How to train your system Getting started with NLTK How to search syntax and tokenize sentences Automatic text summarization Stemming word and topic modeling with NLTK Using scikit-learn for text classification Part of speech tagging and POS tagging models in NLTK And much, much more...

Sprachanwendungen wie Amazon Alexa und Google Translate sind heute allgegenwärtig. Grundlage dafür ist das Natural Language Processing (NLP), das zahllose Möglichkeiten für die Entwicklung intelligenter, Deep-Learning-basierter Anwendungen eröffnet. In diesem Buch lernen Sie die neuesten Techniken zur Verarbeitung von Sprache kennen und nutzen dabei das flexible Deep-Learning-Framework PyTorch. Delip Rao und Brian McMahan geben Ihnen einen Überblick über NLP-Methoden und Grundkonzepte neuronaler Netze und demonstrieren Ihnen dann, wie Sie Sprachanwendungen mit PyTorch entwickeln. Der umfangreiche Beispielcode unterstützt Sie dabei, die gezeigten Techniken nachzuvollziehen und auf Ihre konkreten Aufgabenstellungen zu übertragen. Erkunden Sie Berechnungsgraphen und das Paradigma des überwachten Lernens Beherrschen Sie die Grundlagen der PyTorch-Bibliothek, die für Tensor-Manipulationen optimiert wurde Verschaffen Sie sich einen Überblick über traditionelle NLP-Konzepte und -Methoden Machen Sie sich mit den Grundkonzepten von neuronalen Netzen vertraut Untersuchen Sie Feedforward-Netze, wie zum Beispiel das mehrschichtige Perzeptron Verwenden Sie Einbettungen, um Wörter, Sätze, Dokumente und andere Features darzustellen Verstehen Sie, wie sich Sequenzdaten mit rekurrenten neuronalen Netzen modellieren lassen Erkunden Sie Sequenzvoraussagen und generieren Sie Sequenz-zu-Sequenz-Modelle Lernen Sie Entwurfsmuster für den Aufbau von produktionsreifen NLP-Systemen kennen "Ein fantastisches Buch, um in NLP und Deep Learning mit PyTorch einzutauchen. Delip und Brian haben großartige Arbeit geleistet, sie erklären NLP-Konzepte verständlich und demonstrieren sie in jedem Kapitel anhand von Beispielcode, um damit praktische NLPAufgaben zu lösen." — Liling Tan Research Scientist bei Rakuten

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 representations Perform document classification and topic modeling Steer the model selection process with visual diagnostics Extract key phrases, named entities, and graph structures to reason about data in text Build a dialog framework to enable chatbots and language-driven interaction Use Spark to scale processing power and neural networks to scale model complexity
