EXTRAKT's functions are:

• DETECT LANGUAGE (DL)

it identifies the language of a text, even if terms of different languages are mixed.

• INDEX / ANALYZE / INDEX2 / SUMUP

These 4 functions analyze the text.

The INDEX functions returns the basic forms, the ANALYZE functions adds logical operators which combine the baisc forms (for instance the parts of a compound word in German). The INDEX2 function splits the text into sentences and carries out a Named Entity Extraction, by this mean identifies persons, proper names (companies, institutions, products), geografical terms and dates. The SUMUP function "summarizes" a text.

• GENERATE

The GENERATE function generates all morphological variants to a given basic form (lemma).
The generation can be limited to variants with different stems. 
  

• TRANSLATE

The TRANSLATE function translates the basic forms from one language (source language) into another language (target language). The language pairs are:

- from any of the Extrakt languages into English and German - French, German - Italian and vice versa.   

• SYNONYM

The SYNONYM function combines synonyms, associated terms and derivations. The Syn-Filter combines reduces the list of synonyms by filtering them against a list of predefined terms (usefull with e-shops with a specific vocabulary).

• THESAURUS

The THESAURUS function combines a given term with hyponyms and hypernyms.

• TRAPHO

The TRAPHO function transforms a word into a phonetic representation.
