Build a POS tagger with an LSTM using Keras

In this tutorial, we’re going to implement a POS Tagger with Keras. On this blog, we’ve already covered the theory behind POS taggers: POS Tagger with Decision Trees and POS Tagger with Conditional Random Field. Recently we also started looking at Deep Learning, using Keras, a popular Python Library. You can get started with Keras […]

Getting started with Keras for NLP

In the previous tutorial on Deep Learning, we’ve built a super simple network with numpy. I figured that the best next step is to jump right in and build some deep learning models for text. The best way to do this at the time of writing is by using Keras . What is Keras? Keras […]

Roundup of Python NLP Libraries

The purpose of this post is to gather into a list, the most important libraries in the Python NLP libraries ecosystem. This list is important because Python is by far the most popular language for doing Natural Language Processing. This list is constantly updated as new libraries come into existence. In case you are looking […]

Introduction to Deep Learning

Introduction to Deep Learning – Sentiment Analysis

Deep Learning is one of those hyper-hyped subjects that everybody is talking about and everybody claims they’re doing. In certain cases, startups just need to mention they use Deep Learning and they instantly get appreciation. Deep Learning is indeed a powerful technology, but it’s not an answer to every problem. It’s also not magic like […]

Word Embeddings Cover

Complete Guide to Word Embeddings

Introduction We talked briefly about word embeddings (also known as word vectors) in the spaCy tutorial. SpaCy has word vectors included in its models. This tutorial will go deep into the intricacies of how to compute them and their different applications.

Complete Guide to spaCy

Updates 29-Apr-2018 – Fixed import in extension code (Thanks Ruben) spaCy is a relatively new framework in the Python Natural Language Processing environment but it quickly gains ground and will most likely become the de facto library. There are some really good reasons for its popularity:

Complete Guide to Topic Modeling

Complete Guide to Topic Modeling

What is Topic Modeling? Topic modelling, in the context of Natural Language Processing, is described as a method of uncovering hidden structure in a collection of texts. Although that is indeed true it is also a pretty useless definition. Let’s define topic modeling in more practical terms.

Quick Recipe: Building Word Clouds

What are Word Clouds? Word Clouds are a popular way of displaying how important words are in a collection of texts. Basically, the more frequent the word is, the greater space it occupies in the image. One of the uses of Word Clouds is to help us get an intuition about what the collection of […]
