To cluster information, take a snapshot of data that HPE IDOL Server stores. You can then automatically cluster the data in this snapshot (you do not need to set up an initial taxonomy).
HPE IDOL Server takes a snapshot of the data that it stores and, based on these snapshots, clusters related information together. Each cluster represents a concept area that contains a set of items, which share common properties.
ClusterSnapshot action allows you to take a snapshot of the data stored in the HPE IDOL Server data index. By default this includes data for the HPE IDOL Server databases
Archive. A snapshot represents the content of the data index at a particular time, and enables you to generate cluster information and spectrographs at a later point, even if the data index has changed. You can use a single snapshot to generate both cluster information and spectrograph data to save processing time.
The action adds a timestamp to each snapshot (with the
AUTNDATE) and stores it in binary
.cls format in the
Snapshots subdirectory of the
Cluster directory in your HPE IDOL Server installation directory. This process allows you to have several snapshots with the same name (for example, of one particular HPE IDOL Server) and snapshots with different names (for example, of different data sets).
The results of
ClusterSnapshot are saved as a named snapshot job. You can specify that job name when taking other actions on the snapshot data. You can also set up a schedule that runs the
ClusterSnapshot action at regular intervals.
The HPE IDOL Server data index that you take a snapshot of must ideally contain at least several thousand documents with good quality content (that is, relevant text for various topics).
