This is known as ‘unsupervised’ machine learning because it doesn’t require a predefined list of tags or training data that’s been previously classified by humans. The goal here is to a) identify the topics within news articles and b) identify the sentiment of each topic. To achieve this, our approach is as follows: Create the topic modelling class – TopicModel() Load and process data (we only parse 10K data, otherwise it takes too long) Create dictionary, bow corpus, and topic model Topic modelling is the new revolution in text mining. It is a statistical technique for revealing the underlying semantic structure in large collection of documents. After analysing approximately 300 research articles on topic modeling, a comprehensive survey on topic modelling has been presented in this paper. Topic Modelling & Sentiment Analysis. The goal here is to a) identify the topics within news articles and b) identify the sentiment of each topic.

Introduction to Topic Modelling • Topic modelling is an unsupervised text mining approach. • Input: A corpus of unstructured text documents (e.g. news articles, tweets, speeches etc). No prior annotation or training set is typically required. 5 • Output: A set of k topics, each of which is represented by: 1.
