Text analytics involves getting insights from text content in documents, books, social media, and various other sources. A common requirement is to find the correlation of text content across sources to get a comprehensive picture.

In this Tech Talk we will be discussing a pattern that does just that: correlating text content across various sources for data analytics. We use Watson Natural Language Understanding (NLU), Python Natural Language Processing Toolkit (NLTK), and IBM Data Science Experience (DSX) to build a graph of entities with attributes and use its relationship with other entities to establish correlations within several sources.
