Text-Driven Forecasting
Objectives
Develop machine learning algorithms for predict numeric quantities about an event given a body of text in natural language.
Example
A movie by a famous director has just premiered and generates a lot of user content in the social media (Twitter, Blogspot, Facebook, Google+). Many posts express a negative feeling about the movie. Can we predict a modest gross revenue for this movie?
Description
The goal of text-driven forecasting is to build a system that is able to predict numeric quantities given a body of text in natural language. Examples are: predicting the revenue of movies from Twitter posts, predicting opinion polls from blogs, predicting stock volatility given financial reports, predicting the number of external links given a news article, etc. The goal of this project is to apply machine learning techniques, such as regression, for this task.
Requisites
There are no mandatory requisites. Some programming experience (in languages like C/C++, Java, Python, Matlab, etc) is preferred.
Expected result
At the end of the project, the student should have created a system able to predict numeric quantities about an event given a body of text in natural language.
