Assume the Search Engine Retrieved the following documents sorted by the cosine between the documents and queryo1 in descending order (Doc1, Doc3, Doc4, Doc5, Doc6, Doc2. Doc9. Doc8, Doc7). We Assume that there are 5 relevant documents to the query which are: Doc1, Doc2. Doc4. Doco, and Doc7. What are the recall values at each rank?
