- SourceKey
- Specifies the source key (the names of the edges table columns that identify the target vertex). If you specify sources_table, the function uses only the vertices in sources_table as sources (which must be a subset of those that this argument specifies).
The function uses these names to construct the column names for recommended hub nodes in the output table.
- TargetKey
- Specifies the target key (the names of the edges table columns that identify the target vertex). If you specify targets_table, the function uses only the vertices in targets_table as targets (which must be a subset of those that this argument specifies).
- EdgeWeight
- [Optional] Specifies the name of the edges table column that contains edge weights. Each edge_weight is a positive value. Default behavior: Each edge_weight is 1; that is, the graph is unweighted.
- MaxHubNum
- Specifies the maximum number of hub vertices with the highest score output for each hub vertex. The max_hubs must be an INTEGER.
- MaxAuthorityNum
- Specifies the maximum number of authority vertices with the highest score output for each hub vertex. The max_authority must be an INTEGER.
- Accumulate
- [Optional] Specifies the name of the vertices table columns to copy to the output table.
- TeleportProb
- [Optional] Specifies the probability ε, a DOUBLE PRECISION value between 0 and 1 that represents the jump to the seed vertex during random walk. Default: 0.15.
- RandomWalkLength
- [Optional] Specifies the random walk length L for each hub vertex. L must be an INTEGER. The final hub/authority score is computed as ε*K v/L , where K v is the number of times that the random walk visits vertex v. Default: 5000.
