Aim
The information society needs both rapid and sophisticated technologies able to extract knowledge from huge repositories of unstructured data. In this context, there is a growing demand for applications that perform strong text mining processing, including improving web search engines, providing services for human-machine interaction systems, e-learning, information extraction and opinion mining, and much more. The course will give an overview of methodologies and tools in the field of Computational Linguistics, useful for operating actively in this sector starting from a background both in computer science and in human sciences. We will provide an introduction to recent approaches and technologies in text mining, with particular attention on vector-based representations of word meanings and machine learning algorithms.
