Annotated bibliography was done in week 5. The bibliography was done on the 12 papers which were chosen in week 2. The problem faced was that few papers chosen previously had to be replaced because they had irrevelent data and were out of scope of the project. So in their place new papers had to be chosen and included in the bibliography. This week helped in defining the scope of the project as the papers helped in understanding what will be included in the research by following their future direction.
