Use Case Diagram
I think diagram is well prepared , in addition I was having some troubles
with use case diagram in terms off include and extend concept
but while looking through the diagram I got the point so it was a useful
example for me. The only thing İ can offer is to add the search preferences
that your group has mentioned on requirements of the project and filtering
system should be added on the diagram.
Sequence Diagram
First of all, I liked that you have prepared detailed diagrams that I understand
all consept easily . I choose the last of them and I can't report an error,however
I can suggest you to take the recommendation list before acoording to creators choices
made before than after some tags the recommendation list can change while choosing tags.
Activity Diagram
I choose the diagram 2 I can say it is well prepared and easy to understand may be there
can be an additional control for empty strings and validity.
Class Diagram
I read the other comments of my group there is a rate problem :) But I can say
if you don't control the repetitive topics name you have to use a topic id.
