LYSGROUP: Adapting a Spanish microtext normalization system to English

In this article we describe the microtext normalization system we have used to participate in the Normalization of Noisy Text Task of the ACL W-NUT 2015 Workshop. Our normalization system was originally developed for text mining tasks on Spanish tweets. Our main goals during its development were flexibility, scalability and maintainability, in order to test a wide variety of approximations to the problem at hand with minimum effort. We will pay special attention to the process of adapting the components of our system to deal with English tweets which, as we will show, was achieved without major modifications of its base structure.
