UDon2: a library for manipulating Universal Dependencies trees
Dmytro Kalpakchi | Johan Boye
Proceedings of the Fourth Workshop on Universal Dependencies (UDW 2020)

UDon2 is an open-source library for manipulating dependency trees represented in the CoNLL-U format. The library is compatible with the Universal Dependencies. UDon2 is aimed at developers of downstream Natural Language Processing applications that require manipulating dependency trees on the sentence level (in addition to other available tools geared towards working with treebanks).

SpaceRefNet: a neural approach to spatial reference resolution in a real city environment
Dmytro Kalpakchi | Johan Boye
Proceedings of the 20th Annual SIGdial Meeting on Discourse and Dialogue

Adding interactive capabilities to pedestrian wayfinding systems in the form of spoken dialogue will make them more natural to humans. Such an interactive wayfinding system needs to continuously understand and interpret pedestrian’s utterances referring to the spatial context. Achieving this requires the system to identify exophoric referring expressions in the utterances, and link these expressions to the geographic entities in the vicinity. This exophoric spatial reference resolution problem is difficult, as there are often several dozens of candidate referents. We present a neural network-based approach for identifying pedestrian’s references (using a network called RefNet) and resolving them to appropriate geographic objects (using a network called SpaceRefNet). Both methods show promising results beating the respective baselines and earlier reported results in the literature.

SpaceRef: A corpus of street-level geographic descriptions
Jana Götze | Johan Boye
Proceedings of the Tenth International Conference on Language Resources and Evaluation (LREC'16)

This article describes SPACEREF, a corpus of street-level geographic descriptions. Pedestrians are walking a route in a (real) urban environment, describing their actions. Their position is automatically logged, their speech is manually transcribed, and their references to objects are manually annotated with respect to a crowdsourced geographic database. We describe how the data was collected and annotated, and how it has been used in the context of creating resources for an automatic pedestrian navigation system.
