| == Where to find ==
| |
| | |
| Access is given via the [[analysis tab]] in the left-hand side of the visone window:
| |
| set ''level'' to '''grouping''', set ''class'' to '''clustering''', and set ''measure'' to '''triadic cohesion clustering (TCC)'''.

| == How to use ==
| |
| | |
| === Configuration ===
| |
| | |
| ==== link strength ====
| |
| | |
| For each node, the algorithm will rank its neighborhood (outgoing links) according to the provided link strength attribute.
| |
| * If '''uniform''' is selected (default), links are first weighted according to their Simmelian strength and afterwards ranked according to this newly created link attribute (termed ''triadType300'').
| |
| * '''Otherwise''', the rankings will be calculated according to the link strength attribute that was provided.
| |

| |
| | |
| | |
| For designated pairs of nodes, the algorithm will calculate the overlap of top-ranked other nodes in their neighborhoods.
| |
| Only connected pairs of actors will be compared.
| |
| | |
| ==== restricted ====
| |
| | |
| Use this parameter to further restrict for which pairs of actors the overlap of top-ranked neighborhoods is calculated:
| |
| | |
| * if selected (default), the overlap calculation is restricted to those links which have been top-ranked themselves
| |
| * if de-selected, the overlap calculation is performed for each pair of connected actors
| |
| | |
| ==== max ranking ====
| |
| | |
| You can use the ''max ranking'' parameter to specify the maximal rank which is still reagrded as top-rank.
| |
| That is, those neighbors that have been attached a rank greater than ''max ranking'' will be disregarded when calculating the overlap.
| |
| (Setting ''max ranking'' to zero will imply zero/undefined overlap values.)
| |
| | |
| ==== min overlap ====
| |
| | |
| You can use the ''min overlap'' parameter to specify a minimal required overlap for the corresponding link not to be removed from the network.
| |
| Setting ''min overlap'' to zero will imply that only links with undefined overlap value are removed from the network.
| |
| | |
| === Execution and result ===
| |
| | |
| The resulting neighborhood rankings are saved in a link attribute termed ''rank'', the resulting overlap values are saved in a link attribute termed ''overlap''.
