This is an application for the user-driven visualization of dependency structures for German (from TiGerDB) as Extended Linguistic Dependency Diagrams (xLDD). To see a dependency structure, choose a sentence number from the TiGer data in the correpsonding drop down menu.

You can specify and alter the visual encodings of text and arcs according to the dependency relations and additional information associated with tokens of the dependency structure. The encoding alternatives are limited to a predefined subset of visual encodings offered by the xLDD tool. This results in an easy-to-use but yet fairly flexible tool. For an example of more detailed settings, see the PAISÀ example.

The diagrams allow you to encode information in various ways to make it easier to see patterns quickly.

For the encoding of dependency relations you can select one or more dependencies from a list and assign to them an encoding. As well you can choose an encoding for the unselected relations. The options for encodings of dependency relations are:

Token level information can be encoded for words, lemmas and parts of speech (pos), by naming them in a comma separated list. Encoding options for token information include:

You can explore the diagram in a variety of ways:

Show arcs for dependency relation(s) as and all other arcs as

Show tokens of the (items separated by commas) as
