Parsed output

The FstReader object recognizes the SFST patterns for a token and for a sequence of analyses, and from pairings of tokens and analyses creates AnalyticalTokens.

An AnalyticalToken in turn associates a literal token String with a (possibly empty) Vector of LemmatizedForms. The LemmatizedForm is a trait associating the literal token with a single morphological analysis from a single lexeme. The LemmatizedForm trait requires ID strings for:

• the lexeme
• the applied rule
• the applied stem
• a “part of speech” label

The apply function of the LemmatizedForm object considers a single line of SFST output and makes an Option[LemmatizedForm]. (Its value is None if the LemmatizedForm object cannot parse the string).

The LemmatizedForm trait is implemented by classes for possible analytical pattern, namely:

• VerbForm (conjugated verb form): analytical pattern PNTMV. See an example.
• ParticipleForm: analytical pattern GCNTV
• InfinitiveForm: analytical pattern TV
• GerundiveForm: analytical pattern GCN
• GerundForm: analytical pattern C
• SupineForm: analytical pattern C
• AdverbForm: analytical pattern D
• NounForm: analytical pattern GCN
• AdjectiveForm: analytical pattern GCND
• IndeclinableForm: analytical pattern Pos
