Yes, the equation is known as TF-IDF. It stands for Term-Frequency, Inverse Document Frequency.Here is more info: http://en.wikipedia.org/wiki/Tf*idf
It states that a word is a keyword in this document, if it is common in this document, and uncommon elsewhere. So for example a word like '*dog*' will be a keyword, but it will ignore certain words like '*the*' or '*and*'. Then find other documents with similar keywords. Also, ideally you do not deal with words themselves, but rather the stems of the words. So for example dog and dogs should map to the same stem. The best algorithm for this is the Porter Stemming algorithm.
