Extraction

The models generated in a thesaurus project extract the occurrences of the taxonomy concepts from documents. In the Extraction tab you find the settings that affect extraction and are used for new concepts. These settings can be overridden at the concept level.

Extraction method

Extraction method is the way generated models will use concepts' labels to determine the portions of text to extract.

Possible methods are:

  • Semantic: all the portions of text expressing the same meaning of the concept labels, in any inflected form. For example, for the label sandglass: sandglass, hourglass, sandglasses, hourglasses.
  • Base form: all the inflections of the label considered as a lemma (the base form or dictionary entry). For example, for the label sandglass: sandglass, sandglasses.
  • Exact label: only exact matches of the labels.

Context settings

The context is the subdivision of the text or the sequence of subdivisions in which to search for the expressions of the concept to be extracted.

Warning

Not all parts of a text correspond to clauses. For example, a heading like:

Disclaimer

may not be considered a clause, so be aware that if you set Clause as context, there may be portions of the document text in which extraction will not take place.

The context also serves in combination with the specification of terms that must or must not co-occur in the vicinity of the term corresponding to the concept to be extracted. Co-occurrence constraints can be set at the concept level.
