								 preference_space = preference_space,
								 recommender_approach = 'user_based',
								 number_of_items_to_recommend = 10,
								 similarity_measure = 'euclidean_distance')

The preference space is dictionary data structure where keys are users and values are dictionary of items and ratings

preference_space = {
					'userA : {
							 'item1' : 'ratingA1, 
							 'item2' : 'ratingA2',
							  ..., 
							  'itemn' : 'ratingAn
							  }, 
					...,
