Fast Whitespace Correction with Encoder-Only Transformers (2023.acl-demo)
Copied to clipboard
| Challenge: | a new tool for whitespace correction is available for text with spurious spaces . the tool is 900 times faster than the previous best tool for text correction . |
| Approach: | They propose to combine whitespace correction with a character-level encoder-decoder model and a byte-level byte encoder only model to improve quality. |
| Outcome: | The proposed tool is over 900 times faster than the previous best tool, with the same high quality. |
A Fair and In-Depth Evaluation of Existing End-to-End Entity Linking Systems (2023.emnlp-main)
Copied to clipboard
| Challenge: | Existing evaluations of entity linking systems often lack detailed error analysis or a closer look at the results. |
| Approach: | They evaluate existing entity linking systems and propose two new benchmarks . they characterize their strengths and weaknesses and report on reproducibility aspects . |
| Outcome: | The evaluations of existing system have strong biases and artifacts . they characterize their strengths and weaknesses and report on reproducibility aspects . |
ELEVANT: A Fully Automatic Fine-Grained Entity Linking Evaluation and Analysis Tool (2022.emnlp-demos)
Copied to clipboard
| Challenge: | a tool for fine-grained evaluation of entity linkers on benchmarks is presented . a typical evaluation shows that overall precision and recall are poor . particular benchmarks often require very particular skills from an entity linker . |
| Approach: | They propose a tool for fine-grained evaluation of entity linkers on benchmarks . they use a graph-based tool to analyze performance of a set of entity links . |
| Outcome: | The proposed tool provides an automatic breakdown of the performance by error categories and by entity type. |
