Classifier plugin for generating hierarchical classifications based on a supplementary structure file.
The following table lists all of the configuration options available for HFileHierarchy.
| Option | Description | Value |
|---|---|---|
| HFileHierarchy Options | ||
| metadata | (REQUIRED) A single metadata field, or a comma separated list of metadata fields, used for classification. If a list is specified, the first metadata type that has values will be used. May be used in conjunction with the -firstvalueonly and -allvalues flags, to select only the first value, or all metadata values from the list. | |
| firstvalueonly | Use only the first metadata value found. | |
| allvalues | Use all metadata values found. | |
| hfile | Use the specified classification structure file. | |
| sort | Metadata field to sort leaf nodes by. Leaves will not be sorted if not specified. | |
| reverse_sort | Sort leaf nodes in reverse order (use with -sort). | |
| hlist_at_top | Display the first level of the classification horizontally. | |
| documents_last | Display document nodes after classifier nodes. | |
| Options Inherited from BaseClassifier | ||
| buttonname | The label for the classifier screen and button in navigation bar. The default is the metadata element specified with -metadata. | |
| no_metadata_formatting | Don't do any automatic metadata formatting (for sorting.) | |
| builddir | Where to put the built indexes. | |
| outhandle | The file handle to write output to. | Default: STDERR |
| verbosity | Controls the quantity of output. 0=none, 3=lots. | Default: 2 |
