- construct_pr_adj_matrix(graph: structures.graph.Graph, ordered_list: list)
- Calculates Adjacency matrix needed for PageRank
M[i,j] ->
0 (if j and i are not connected)
1 / number of outgoing links from j (if link from j to i exists)
Sum of each column is 1.
:param graph: graph from a PopulateStructures object
:param ordered_list: ordered HTML files list (PopulateStructures object)
:return: pagerank adjacent matrix
- pagerank(M, num_iterations: int = 100, d: float = 0.85)
- PageRank: The trillion dollar algorithm.
Parameters
----------
M : numpy array
adjacency matrix where M_i,j represents the link from 'j' to 'i', such that for all 'j'
sum(i, M_i,j) = 1
num_iterations : int, optional
number of iterations, by default 100
d : float, optional
damping factor, by default 0.85
Returns
-------
numpy array
a vector of ranks such that v_i is the i-th rank from [0, 1],
v sums to 1
