Understanding Sentiment in Natural Language with BiLSTMs
Natural Language Understanding (NLU) is a significant subfield of Natural Language Processing (NLP). In the last decade, there has been a resurgence of interest in this field with the dramatic success of chatbots such as Amazon's Alexa and Apple's Siri. This chapter will introduce the broad area of NLU and its main applications.
Specific model architectures called Recurrent Neural Networks (RNNs), with special units called Long Short-Term Memory (LSTM) units, have been developed to make the task of understanding natural language easier. LSTMs in NLP are analogous to convolution blocks in computer vision. We will take two examples to build models that can understand natural language. ...
