I did it exactly the same and got the same answer.. but I think the recommended page for (b) should only be P7 because the problem states: (b) Use the closest neighbor method to recommend a page to the user who made T3. so, I'm thinking that user has reached P6, and now what's the recommendation.. which is P7 let me know.. |

Sorry I was wrong. Ansuya's solutions for both parts are correct. |

This might be another way to solve Part B. |

That's incorrect. What you did was basically calculating half a Jaccard coefficient (i.e. A intercept B), but you missed the other half (i.e. A union B). |
