Where Do We Go From Here? Multi-scale Allocentric Relational Inferencefrom Natural Spatial Descriptions (2024.eacl-long)
Copied to clipboard
| Challenge: | Current NLP navigation studies focus on egocentric local descriptions that require reasoning over the agent’s local perception. |
| Approach: | They propose to use a dataset to analyse English geospatial instructions to find locations and paths from natural language descriptions. |
| Outcome: | The proposed task and dataset includes 10,404 examples of English geospatial instructions for reaching a target location using map-knowledge. |

Diptesh Kanojia, Prashant Sharma, Sayali Ghodekar, Pushpak Bhattacharyya, Gholamreza Haffari, Malhar Kulkarni
| Challenge: | Existing approaches to cognate detection use orthographic, phonetic and semantic similarity based features sets. |
| Approach: | They propose a method for enriching feature sets with cognitive features extracted from gaze behaviour data from human readers’ gaze behaviour. |
| Outcome: | The proposed method improves cognate detection performance by 10% and 12% over existing methods. |
Into the Unknown: Generating Geospatial Descriptions for New Environments (2024.findings-acl)
Copied to clipboard
| Challenge: | Similar to vision-and-language navigation tasks, the Rendezvous (RVS) task requires reasoning over allocentric spatial relationships using non-sequential navigation instructions and maps. |
| Approach: | They propose a large-scale augmentation method for generating high-quality synthetic data for new environments using readily available geospatial data. |
| Outcome: | The proposed method improves accuracy on unseen and seen environments by 45.83% on the Rendezvous (RVS) task. |
