| Argument | Category | Description |
|---|---|---|
| SourceKey | Required | Specifies the source key (the names of the edges table columns that identify the target vertex). If you specify sources_table, then 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 | Required | Specifies the target key (the names of the edges table columns that identify the target vertex). If you specify targets_table, then 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. By default, each edge_weight is 1; that is, the graph is unweighted. |
| MaxHubNum | Required | Specifies the maximum number of hub vertices with the highest score output for each hub vertex. The max_hubs must be an INTEGER. |
| MaxAuthorityNum | Required | 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. |
| TeleprotProb | Optional | Specifies the possibility ε, a DOUBLE PRECISION value between 0 and 1 that represents the jump to the seed vertex during random walk. The default value is 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. The default value is 5000. |
