+Individual's names contain information about their ethnic ancestory and culture (broadly defined). The purpose of this project is to create a classifier that given an individual's name can deduce, with good accuracy, their culture.
-[[Sources of Surname Data]]
+Classification tecnhiques use variations in the features of their subjects to predict classes. In the classic example (see R.A. Fisher 1936), a classifier for types of plant used the features "petal width", "petal length", and so forth. In our context features refer to properties of names, specifically the length of the name string, the frequency of occurance of n-grams, and so forth.
-[[Normalizing Surnames]]
+An n-gram is a combination of characters (a gram) of length "n". For example, using a 2-gram, also called a bigram or a digraph, the surname "EGAN" has frequency of one for the grams EG, GA, and AN, and a frequency of zero for all other grams from AA to ZZ.
