Select a local file containing one or many dependency structures in CoNLL-U format. It is also possible to drag and drop a file on the page. An initial UD file is loaded at the beginning of the program.
Select the fields used to filter the content of the file that will be inserted in the table by clicking on its conventional name
When shown in blue, a text field then appears in which a regular expression can be typed. This expression is used as filtering when parsing the text field, it is ignored when no regex is typed. Regular expression matching is case-insensitive when the checkbox Ignore Case is checked (true by default).
Clicking on a blue field puts a bar over it to indicate that the regex is complemented, similar to -v in grep.
Clicking on a complemented blue field deselects it, so its value is not used in filtering.
The checkbox between FORM and LEMMA allows selecting tokens for which their form and lemma are the same, ignoring case. When the checkbox is indeterminate (i.e. it shows "-"), it selects tokens for which their form and lemma differ.
Click on the Parse button to fill the table with the tokens that match the filters. To keep the browser responsive, only the first tokens with fields matching the corresponding regex are displayed as rows in the table.
When Parse button is red, it means that an input selection filter has been changed, click it to refill the table with the current selection on the same data.
The table can be scrolled vertically and columns can be sorted by clicking in the header.
Clicking a cell in the table will display information about the sentence containing this token which is shown in bold. It also displays the dependency graph or tree of the sentence in which hovering a token shows its ID, LEMMA, UPOS and FEATS in a tooltip.
Clicking on the Token table creates a new tab listing all current tokens with their sent_id which can be saved or printed.
