Errata of the Textbook

Page vii: should read "David Harrison".
Page 27 (section 2.5.3): The second of the denominators in the equation lists a summing of the query terms from j=1 to t. This should be from i=1 to t.
Page 136: The correct meaning of MIDF is maximum inverse document frequency.
In chapter 5, Rocchio was spelled consistently wrong. However, the correct spelling is in the appropriate references.
Page 171: title of subsection 7.2.5 should say "Thesaurus" instead of "Theasurus"
Page 195, Table 8.1, "right" and "left" should be switched.
Page 210: j-next[j]+1 should be j-next[j]-1
Page 212: Note that the examples in the text and in figure 8.16 are not the same.
Page 213: All 0's and 1's in Figure 8.17 should be reversed (we originally had also the Shift And description of the algorithm).
Page 373: Change "That is, 9.3 Kb is the cut point between both distributions" by "The cut point between both distributions is then larger than 9.3 Kb (such that the whole probability adds to 1)".
Page 381: In the last formula, the first term of PR(a) should be modified from q to q/P where P is the total number of pages.
Page 474, Reference 352: should read "H.S. Heaps".
