Recent Data Science Project

Healthcare Twitter Analysis Project (Saama Technologies, USA)

The goal of Saama Technologies healthcare Twitter analysis project is to gain meaningful insights into American healthcare and medicine by analysing data on the social media website Twitter along with government data and live events data. The project aims to achieve the above goals by deploying machine learning methods to analyse data. The analysis for the project can take the form of any of the common machine learning problem domains like classification, regression, clustering, sentiment analysis etc. Moreover, extensive text analysis and natural language processing (NLP) methods are expected to be used for processing the textual data.

The project as described above is an umbrella project and has a very wide scope. Smaller projects with narrower scope are expected to be carried out to fulfil the goal of the umbrella project. All projects are expected to contribute to the goal of the umbrella project, which is to understand the themes and patterns in tweets, government data and the live data.

The objective of this particular project was to explore ‘cancer’ related tweets with a view to discover some ‘cancer’ related themes. The project objective was met by using machine learning algorithms to discover topics in tweets, manually interpreting topics to identify themes and by performing some content analysis on tweets. The project was implemented by using Python 3.5.

Project Problem Statement:

a) Develop topic models from ‘cancer’ related tweets in order to identify some ‘cancer’ related themes.

b) Analyse the content and describe the themes in tweets.

c) Summarise the findings of topic analysis and content analysis.
