NSA

A method of identifying a topic of a text. Text is received. Then, the nouns in the text are identified. The singular form of each identified noun is determined. Combinations are created of the singular form of the identified nouns, where the number of singular forms of the nouns in the combinations is user-definable. The frequency of occurrence in the text of each noun that corresponds to its singular form is determined. Each frequency of occurrence is assigned as a score to its corresponding singular form noun. Each combination of singular form nouns is assigned a score that is equal to the sum of the scores of its constituent singular form nouns. The user-definable number of top scoring singular form nouns and combinations of singular form nouns are selected as the topic of the text.
