Patrick Littell, Tom McCoy, Na-Rae Han, Shruti Rijhwani, Zaid Sheikh, David Mortensen, Teruko Mitamura, Lori Levin
| Challenge: | morphological parsers for two Afroasiatic languages are developed using a parser-combinator paradigm . the paradigm allows rapid development and ease of integration with other systems, but at a cost of non-optimal theoretical efficiency. |
| Approach: | They propose a rule-based morphological parser paradigm for Tigrinya and Oromo languages . they use a parsers-combinator paradigm instead of a finite-state paradigm . |
| Outcome: | The proposed paradigm allows rapid development and ease of integration with other systems, but at cost of non-optimal theoretical efficiency. |
Building Universal Dependency Treebanks in Korean (L18-1)
Copied to clipboard
| Challenge: | Several treebanks were introduced for Korean, all of which comprised annotation of morphemes and phrase structure trees, each following its own set of guidelines. |
| Approach: | They propose to use Korean treebanks as dependency trees and to analyze their performance using morpheme-level annotations. |
| Outcome: | The Korean portion of the Google UD Treebank, the Penn Korean Treebank and the KAIST Treebank are re-tokenized and assessed for errors. |
