The second homework focuses on index construction and vector space model, which includes: 1. Consider the following document-term table with 10 documents and 8 terms (A through H) containing raw term frequencies. We also have a specified query, Q, with the indicated raw term weights (the bottom row in the table). Answer the following questions, and in each case give the formulas you used to perform the necessary computations. Note: do this using a spreadsheet program such as Microsoft Excel. Alternatively, you can write a program to perform the computations. Please include your worksheets or code in the assignment submission.
