Introduction

MasKIT is an on-line tool and REST API service for anonymization (pseudonymization) of Czech legal texts. Taking a plain text as input (e.g., a letter sent by a legal authority to a citizen), it runs external services for dependency parsing and named entity recognition and then identifies and replaces personal information in the text.

The software is available under the Creative Commons Mozilla Public License 2.0.
