Currently, one needs to do a CA before being able to do a CAH on a partition or lexical table. This corresponds to FactomineR functions architecture but not to a typical analysis scenario: a user may analyse a CAH on a partition without ever analysing its CA.

Solution¶

• Add the CAH (Classification/Cluster) command
  • on partition
  • lexical table objects.

• If called from the Partition:
  1. create a lexical table with the default parameters
  2. open the LT parameters dialog box (*) for (property to use and Fmin value)
  3. build the LT
  4. build the CA
  5. build the CAH

• If called from a lexical table:
  1. open the CA parameters dialog box (*) for property to use and Fmin value
  2. build it (with default parameters)
  3. create the CAH.

[(*) SH: 'was set word property and Fmin to a default value for CA']
Questions :

• Intermediate object created:
  • SH: We have to decide if in that case the CA result is displayed in the Corpus view or not.
  • MD: The intermediate Lexical Table created when the CA is called from a Partition is shown. So, I prefer to show the Lexical Table and the CA that will be created
• Default parameters:
  • MD: The CA called from the partition show the CA parameters and use the default parameters to create the LT. Should we do the same with de CAH ? (note: the CAH as no parameter dialog, so no parameter is shown)
  • MD: use the same dialog window (word property + fmin + Vmax) for :
    • Lexical Table called from Partition
    • CA called from Partition
    • CAH called from Partition

Validation test¶

• create the "text_id" partition on VOEUX corpus
• select the "text_id" partition
• run the CAH command
• select the created lexical table
• run the CAH command
• the 2 results should be equal
