8. A computer-implemented method comprising: identifying a plurality of terms in a phrase; placing a sliding window having a defined length over a first sequence of terms from the plurality of terms, the first sequence of terms comprising a first term, a second term, and a third term, the first term and the third term being adjacent to the second term; based on the first term, the second term, and the third term, determining whether the second term represents non-natural language; and upon determining that the second term is non-natural language, labeling the second term as non-natural language to omit the second term from content analysis of the phrase.
