A simple tool for reconstructing morphological tags was created using the rules of morphological annotation applied in the Slovak National Corpus. Either a morphological tag with all items defined precisely, or a morphological tag containing regular expressions replacing a specific choice (“.”, “.*“) is inserted into the box after the text TAG =. Confirmation (through ENTER or by clicking on GIVE DETAILS) will display an individual paradigms and categories table. If a position is occupied by a regular expression that has replaced several options, the MULTIPLE OPTIONS item will appear in the table in the relevant line. Move the cursor to this text to see all the options a particular category contains. If you need to proceed in the opposite direction, you will find you can find the tool for creating morphological tags here.
