where action can be one of PageRank, PageRankBL, NetLocRank, and exportLinkGraph. Results on STDOUT.
OPTIONS AND ARGUMENTS
jobname is used to find the appropriate configuration (mandatory)
verbose enables printing of ranks to STDOUT as SQL INSERT statements
Actions calculating variants of PageRank
calculate standard PageRank
calculate PageRanks with backlinks added for each link
calculate SiteRank for each site and a local DocRank for documents within each site. Global ranks are then calulated as SiteRank * DocRank
Actions exporting link data
export linkgraph from Combine database
Implements calculation of different variants of PageRank.
Results are written to STDOUT and can be huge for large databases.
Linkgraph is exported in ASCII as a sparse matrix, one row per line. First integer is the ID (urlid) of a page with links. The rest of integers on the line are IDs for pages linked to. Ie 121 5624 23416 51423 267178 means that page 121 links to pages 5624 23416 51423 267178
combineRank --jobname aatest --verbose PageRankBL
