Patakis is a 100 million word collection of POS-tagged texts mostly downloaded from the Internet, prepared by Milos Husak of Masaryk University, Brno, for Lexical Computing Ltd., in collaboration with the Greek publishers Patakis and the Greek software company Neurolingo.


The tokenization and Part-Of-Speech tagging is based on the NeuroLingo Collection Analyzer, which provides the following information:

Sketch Grammar

The sketch grammar, used for the generation of Greek word sketches and distributional thesaurus, was developed by Mavina Pantazara and Christos Tsalidis of Neurolingo.


The corpus is divided into documents (<doc></doc>) identified by their id. When available, it also contains information about its url, genre, subgenre, language, title, author, year and decade of publishing, publisher, medium, time (epoch of publishing). Each document is further structured using following tags:

paragraphs                <p></p>
sentences                 <s></s>
headers                   <h></h>
lists                    <ul></ul>
list lines               <li></li>
non-greek words   <non-greek></non-greek>
glue                       <g/>

Text gathering

The majority of texts were downloaded using BootCat according to an URL list generated by a list of Greek words provided by Patakis. Some Patakis-owned documents are included under licence (and are not available in the default version of the corpus). The corpus containing solely the texts downloaded from the Internet is called GkWaC.
