Extend information about entities discovered based on WKS dictionaries

at this time, entities discovered based on dictionaries, provide only the type. lemma is discarded although it is a required element in the speciication of dictionary and can also appear in other WKS rules

this is a critical first step element for integration of domain knowledge

    Can you clarify more about how the Type is provided but not the lemma.  I was thinking the "type" would or could be labeled to match the "lemma" (preferred canonical form)?

    WKS allows you to attach dictionaries, which comprise one or more n-tuples, each identifying a lemma (1st field) and equivalent surface forms. like dictionary from  'hardware.csv' comprises n-tuple (hdd, hard disk, disk drive, hard disk drive). In order to be exported in the model for Discovery and NLU, this dictionary. must be associated with a class in the rule based annotator and a type.

    during enrichment-time content analysis, of a sentence like "disk drive must be replaced", NLU or whatever is below, matches "disk drive" to the proper dictionary and generates an entity enrichment. This entity gets a type set to the name of the type, and a text, set to the surface form. BUT there is no mention of the lemma.Lemma is most important for text normalization to improve.

     

    Hope this helps.

    I've been using entity subtypes to achieve what I think you mean to achieve with the lemma.
