Labels are defined by the sets of synonyms.
Besides sentiment lexicons, Neticle also has a lexicon for labels, where the available labels have their corresponding sets of synonyms. The label is recognized in a verbatim only if any of its synonyms can be found in the text, either by matching the beginning of a phrase, or by an exact match (depending on the settings of each label). Some labels can have excluded phrases as well: this prevents the label recognition in texts where the excluded phrase is present.
For example, the English label “import” has one synonym: import. It matches if the beginning of a phrase contains the string import, so the following phrases will be a hit: import, importing, imported, importer, etc. However, it also has two excluded phrases: important, importance. This means that even if a phrase begins with import (a synonym), it will not be a hit if it also begins with any of the excluded phrases.
