Learning Objects (LOs) are pieces of instructional material like traditional texts that can be reused in the composition of more complex objects like classes or courses. There are some difficulties in the process of LO reutilization. One of them is to find pieces of documents that can be used like LOs. In this work we present a process that, in search for LOs, starts by extracting, transforming and loading a text database and then continue clustering these texts, using a machine learning methods that combines EM (Expectation- Maximization) and a Bayesian classifier. We implemented that process in a system called SQLLOMining that uses the SQL language and text mining methods in the search for LOs.
