SConE: Simplified Cone Embeddings with Symbolic Operators for Complex Logical Queries (2023.findings-acl)
Copied to clipboard
| Challenge: | Current geometric-based methods depend on the neural approach to model FOL operators . empirical evidence for explainability is challenging . |
| Approach: | They propose to model conjunction operators using a symbolic modeling approach . they propose to emphasize the essential role of relation projection operator . |
| Outcome: | The proposed method improves answering complex logical queries over previous models. |
MaintIE: A Fine-Grained Annotation Schema and Benchmark for Information Extraction from Maintenance Short Texts (2024.lrec-main)
Copied to clipboard
| Challenge: | Maintenance short texts (MSTs) provide crucial insights into the state and maintenance activities of machines, infrastructure, and other engineered assets. |
| Approach: | They propose a multi-level fine-grained annotation scheme for entity recognition and relation extraction that includes 5 top-level classes and 6 relations tailored to MSTs. |
| Outcome: | The proposed scheme provides high-quality, fine-grained annotations and a coarse-grain corpus of 7,000 texts. |
LexiClean: An annotation tool for rapid multi-task lexical normalisation (2021.emnlp-demo)
Copied to clipboard
| Challenge: | Lexical normalisation is the task of identifying and normalising non-canonical tokens (e.g. erroneous spelling, acronyms, etc.) in noisy, non-standard, corpora. |
| Approach: | They propose to use LexiClean to annotate multiple tasks in noisy corpora using in situ token modification and annotation that can be rapidly applied corpus wide. |
| Outcome: | The proposed tool can be rapidly applied corpus wide and can identify and normalise noisy, non-standard, and domain specific corpora. |
CylE: Cylinder Embeddings for Multi-hop Reasoning over Knowledge Graphs (2023.eacl-main)
Copied to clipboard
| Challenge: | Existing geometric-based models cannot handle the logical negation operation . Existing models using cones embeddings are limited to representing queries by two-dimensional shapes . Empirical results show that the performance of multi-hop reasoning task using CylE significantly increases over state-of-the-art geometric- based models for queries without negation. |
| Approach: | They propose a geometric-based model based on three-dimensional shapes with unbounded cylinder embeddings that can handle a complete set of first-order logic operations. |
| Outcome: | Empirical results show that CylE outperforms state-of-the-art models for queries without negation. |
