Claim One:
1. A computer-implemented method comprising: receiving text at a computer system having one or more processors; detecting, at the computer system, a first segment of the text, where a substantial amount of the first segment represents a first language; detecting, at the computer system, a second segment of the text, where a substantial amount of the second segment represents a second language; obtaining, at the computer system, a first language likelihood for each n-gram of size x included in the text; obtaining, at the computer system, a second language likelihood for each n-gram of size x included in the text; identifying, at the computer system, a score for each n-gram of size x included in the text, where each score represents a difference between the first language likelihood and the second language likelihood; and detecting, at the computer system, an edge including: calculating a first average of the scores for a first group of consecutive n-grams, where consecutive n-grams are defined as including a third n-gram including a first left context and a first right context and a fourth n-gram including a second left context and a second right context, where the second left context is the first right context, where the first group of consecutive n-grams is defined as including a specified number of consecutive n-grams that includes an ending n-gram, calculating a second average of the scores for a second group of consecutive n-grams, and the second group of consecutive n-grams is defined as including a same number of consecutive n-grams that includes a starting n-gram, where the ending n-gram is adjacent to the starting n-gram, and identifying the edge based on a difference between the first average and the second average.
