Select a local file containing one or many dependency structures in CoNLL-U format.
Make sure to select the appropriate annotation scheme: classical UD or Surface Syntactic UD. This selects the mapping between the original deprel names and the ones used by jsRealB.
An initial UD file is loaded at the web page launch. Dragging a file from the finder or explorer on page will load it.
Although there is no a priori limit on the number of UDs that can be loaded in the web page, the system is less responsive and the sentence menu becomes too long when there are more than 1000 sentences.
Click on the Parse button to build the menu.
Select a sentence from the menu. A starting asterisk in a menu item indicates a non-projective dependency structure. Sentences for which jsRealB issued warnings are indicated by a starting exclamation point.
Using checkboxes, the menu can be limited to only generated sentences that differ from the original, to those for which jsRealB issued a warning or to non projective dependencies. Parse must be clicked in order that these options are taken into account.
Once a sentence is chosen in the menu:
The fields of the corresponding dependencies are shown in the table above the menu;
The graph or tree of dependencies is shown below the menu,
the root word is shown in red;
by hovering over a word, the LEMMA, UPOS and FEATS for this token appear in a tooltip;
clicking on the word, selects the corresponding token in the table;
A table showing the line number and ID of the displayed UD, the reference text of the UD
and the English sentence regenerated from the dependencies by jsRealB.
When the reference text and the regenerated sentence differ, the edit operations to transform the latter to the former are displayed using the following conventions: replacement, insertion, deletion. Differences in spacing are ignored.
The jsRealB expression for the generated sentence appears in a text area allowing its edition for re-realization by clicking on the Realize button.
Clicking in a cell in the UD table updates, the line number in the token table. This can be useful for editing the UD in a text editor.
