11. A computer-implemented method of providing search results, the method comprising: accessing, by a processor, a list of legitimate business titles, each legitimate business title including one or more words; generating a matrix of surprisingness values, where each surprisingness value indicates a likelihood of a word appearing in a legitimate business title, by: examining each legitimate business title to identify pairs of words occurring in that title, adding a count value to the matrix for each pair of words identified, such that the matrix includes a plurality of count values for different pairs of words occurring in the legitimate business titles, and normalizing the plurality of count values for the matrix to generate the matrix of surprisingness values, where each surprisingness value of the matrix of surprisingness values indicates how likely a pair of words are to appear in a legitimate business title, receiving a request for information from a client device; identifying a business listing having a title of two or more words as a search result responsive to the request for information; determining a surprisingness value for the business listing based on the two or more words of the title of the business listing and the matrix of surprisingness values; and transmitting to the client device the business listing when the surprisingness value for the business listing is greater than a threshold value.
