Comment on Similarity Measure: Cosine Similarity or Euclidean Distance or Both by Richard

Hi All,
Thanks for providing this greate tutorial. I am new and just start learning about data mining. I am sorry if my question sounds childish. I know how to calculate tf/idf. Thanks for egarcia, now i also know how to calculate cosine similarity. But I have a question.
Lets say i have two documents. each document has 2 words. 1 word is similar in both documents. So the tf/idf would be like doc A (0,0.5) doc B (0,0.5). Should I calculate cosine similarity on tf/idf values? If I do it return 1 while i can see both documents are 50% same not 100%.
Am I missing some thing? Should I calculate cosine similarity only on IDF values or Tf values?
Thanks
