Patents
Pairwise co-occurence of terms within a 7 word window in the US utility patents on a per-year basis. The date associated with each patent is the year of the priority date of the patent.
The three modes of the tensor correspond to year-term-term, and the values are \(log(1+f_{i,j})\), where \(f_{i,j}\) is the frequency in which the words \(i\) and \(j\) appeared in the window. Each \((k,*,*)\) slice of the tensor is symmetric.
