+## Main Purpose  
+As it is known, GEO Database is home to thousands of High-Throughput (HT) genetic expresison experiments. The documentation for each experiment done within the database includes the Growth Conditions (GC) used in it. Unfurtunately they are not registered in a structured way, but they are into text fragments associated with various fields (we call them metadata).  
+Since knowing the GCs of these experiments helps to better understand genetic regulation, it becomes important to extract these conditions. However, doing it manually requires a lot of 
+effort on large data sets.  
+  
+Thats why, our hypothesis is that a predictive model can determine the GCs of thousands of experiments stored in the GEO. Our goal is to generate a report, that will be used by curators to review and validate the GC of the experiments.
