Introduction In this Project, you’ll use the Pomegranate library to build a hidden Markov model for part of speech tagging with a universal tagset. Hidden Markov models have been able to achieve >96% tag accuracy with larger tagsets on realistic text corpora. Hidden Markov models have also been used for speech recognition and Read more…
Part of Speech Tagging Okay, here’s the problem we’re going to solve in this section We have a sentence, for example, “Mary had a little lamb”, and we need to figure out which words are nouns, verbs, adjectives, adverbs, et cetera. Now, a thorough knowledge in grammar is not needed Read more…
In this post, you’ll learn how to read text data from different sources and prepare it for feature extraction. You’ll begin by cleaning it to remove irrelevant items, such as HTML tags. You will then normalize text by converting it into all lowercase, removing punctuations and extra spaces. Next, you Read more…
In this course, you’ll learn Natural Language Processing (NLP) basics, such as how to identify and separate words, how to extract topics in a text, and how to build your own fake news classifier. You’ll also learn how to use basic libraries such as NLTK, alongside libraries which utilize deep Read more…
NLP Overview Welcome to Natural Language Processing. Language is an important medium for human communication. It allows us to convey information, express our ideas, and give instructions to others. Some philosophers argue that it enables us to form complex thoughts and reason about them. It may turn out to be Read more…
In this blog series we will discuss about Question Answering: answering a question on the basis of a number of facts. This task involves using memory: facts are stored in memory, and the question refers back to past information. How do the various models for sequential processing stack up to Read more…
Recently, Rasa has adopted the *space (star-space)model from facebook AI research as their main and active maintained intent classifier; This is not a new idea but it shows a very promising results in comparison with various neural architectures such as CNN or RNN in a various kinds of NLP task Read more…

1. Introduction “When it is not in our power to determine what is true, we ought to act in accordance with what is most probable” – Descartes Besides the development of Computer Vision, Natural Language Processing, or time series prediction; Reinforcement Learning algorithms have also achieved surprising achievements in recent Read more…
In this blog, i want to clarify the big picture of our NLP Pillar, What topic we will cover and how we can grow together in this field Big Picture Knowledge Representation In NLP, knowledge representation related to how you can express your knowledge (text, documents) in features that we Read more…
