Data Analysis with Python

By: David Taieb

Overview of this book

Data Analysis with Python offers a modern approach to data analysis so that you can work with the latest and most powerful Python tools, AI techniques, and open source libraries. Industry expert David Taieb shows you how to bridge data science with the power of programming and algorithms in Python. You'll be working with complex algorithms, and cutting-edge AI in your data analysis. Learn how to analyze data with hands-on examples using Python-based tools and Jupyter Notebook. You'll find the right balance of theory and practice, with extensive code files that you can integrate right into your own data projects. Explore the power of this approach to data analysis by then working with it across key industry case studies. Four fascinating and full projects connect you to the most critical data analysis challenges you’re likely to meet in today. The first of these is an image recognition application with TensorFlow – embracing the importance today of AI in your data analysis. The second industry project analyses social media trends, exploring big data issues and AI approaches to natural language processing. The third case study is a financial portfolio analysis application that engages you with time series analysis - pivotal to many data science applications today. The fourth industry use case dives you into graph algorithms and the power of programming in modern data science. You'll wrap up with a thoughtful look at the future of data science and how it will harness the power of algorithms and artificial intelligence.

Chapter 7. Analytics Study: NLP and Big Data with Twitter Sentiment Analysis

 

"Data is the new oil."

 
 --Unknown

In this chapter we are going to look at two important fields of AI and data science: natural language processing (NLP) and big data analysis. For the supporting sample application, we re-implement the Sentiment analysis of Twitter hashtags project described in Chapter 1, Programming and Data Science – A New Toolset, but this time we leverage Jupyter Notebooks and PixieDust to build live dashboards that analyze data from a stream of tweets related to a particular entity, such as a product offered by a company, for example, to provide sentiment information as well as information about other trending entities extracted from the same tweets. At the end of this chapter, the reader will learn how to integrate cloud-based NLP services such as IBM Watson Natural Language Understanding into their application as well as perform data analysis at (Twitter) scale with frameworks such as Apache...
