Using the xLDD visualization for dependency structures

Extended Linguistic Dependency Diagrams (xLDDs) are graphical representations of dependency relations (for the ISST-TANL dependency tagset see here) which can interactively be customised by the user. The xLDD thumbnail view is offered as an alternative to the standard KWIC display. Each line is showing a small version of the dependency structure for the corresponding sentence, together with the sentence text, as in the KWIC view with expanded context. Double clicking on a small version of a diagram will show a larger version in a new window.

Dependency diagrams can be explored in a variety of ways:

Customizable dependency visualization

In the separate window view you can specify and alter the visual display of both text and arcs with regard to the dependency relations and additional information associated with tokens of the dependency structure. In this view, you can also zoom the diagram in and out, by using the slider or the plus and minus (maximize/minimize) buttons.

For the visual display of dependency relations you can choose among different options. You can also customize the display of unselected relations.

Display options for dependency relations

The options for displaying dependency relations are:

The visual display of up to four dependency relations can be defined.

Display options for words and lemmas

Token level information can be displayed for words and lemmas, by putting them in a comma-separated list. Displaying options for word and lemma information include:

Display options for parts of speech

Part of speech information is visualized on the nodes above each token. The basic visualization shows circular nodes in grey colour. Up to four part-of-speech types can be distinguished visually. Display options are:

Display options are applied to the diagram by clicking on the "submit" button.
