We want to do some calculations like pagerank, cliques, betweeness but before we can do this, we need a sparse matrix dataset. Here you can see a few lines of the matrix (3 columns) "Row","Col","Value" 830,3,1 852,3,1 52591,3,1 114337,3,1 148326,3,1 196849,3,1 ... So how can we make a sparse matrix of this , so we can do our calculations on sparse matrix dataset? Kind regards Bart
