Text spell checks and removal of redundant characters5. Synonyms and Synsets Chapter 4: Feature Engineering for Text DataChapter Goal: This chapter covers important strategies to extract meaningful features from unstructured text data. This includes traditional techniques as well as newer deep learning based methods. No of pages : 40 - 50Sub - Topics: 1. Feature engineering strategies for text data2. Bag of words model3. TF-IDF model3. Bag of N-grams model4. Topic Models5. Word Embedding based models (word2vec, glove) Chapter 5: Text Classification Chapter Goal: Introduces readers to the concept of classification as a supervised machine learning problem and looks at a real world example for classifying text documentsNo of pages: 30 - 40Sub - Topics: 1. Classification basics2. Types of classifiers3. Feature generation of text documents4. Binary and multi-class classification models5. Building a text classifier on real world data with machine learning6. Some coverage of deep learning based classifiers7. Evaluating Classifiers Chapter 6: Text summarization and topic modelingChapter Goal: Introduces the concepts of text summarization, n-gram tagging analysis and topic models to the readers and looks at some real world datasets and hands-on implementations on the sameNo of pages: 40 - 45Sub - Topics: 1. Text summarization concepts2. Dimensionality reduction3. N-gram tagging models4. Topic modeling using LDA and LSA5. Generate topics from real world data6. N-gram analysis to generate patterns from app reviews (only if it performs well)7. Basics on deep learning for summarization Chapter 7: Text Clustering and Similarity analysisChapter Goal: We look at unsupervised machine learning concepts here like text clustering and similarity measuresNo of pages: 35 - 40Sub - Topics: 1. Clustering concepts2. Analyzing text similarity3. Implementing text similarity with cosine, jaccard measures4. Text clustering algorithms5. Coverage of partition based clustering like k-means clustering as well as hierarchical clustering methods in detail 6. Hands on text clustering example on real world data Chapter 8: Sentiment Analysis Chapter Goal: We look at solving a popular problem of analyzing sentiment from text using a combination of methods learnt earlier including classification and also lexical analysisNo of pages: 35 - 40Sub - Topics: 1. What is sentiment analysis2. Looking at lexical corpora for sentiment 3. Unsupervised sentiment analysis using lexical methods (hands-on)4. Supervised sentiment analysis (hands-on) Chapter 9: Deep learning in NLPChapter Goal: Deep Learning is one of the most trending topics in the machine learning and data science space these days. Here we will cover a brief introduction into the promise deep learning holds for text analytics and NLP.No of pages: 30 - 35Sub - Topics: 1. What is Deep Learning2.
