We present an application for period determination and automatic classification of light curves for eclipsing binaries. In this case, we have correlated the list of eclipsing binary stars from The International Variable Star Index (VSX) data base, with The All-Sky Automated Survey (ASAS) and SIMBAD databases. As a result, we have obtained nearly 23 000 light curves for stars with V stellar magnitudes between 7 and 14. About 40% of these stars had not been previously detected by the automatic classification software of the ASAS project, which is motivating for finding new eclipsing binary stars. We show an overall statistics about light curves parameters for the 15 000 stars of our sample, among which almost 10 000 still lack detailed observational studies (less than four bibliographic entries).
