Challenge: OntoLex is a widely used community standard for machine-readable lexical resources on the web.
Approach: They propose a module for representing morphology that can be used to encode and integrate morphological resources on a unified basis.
Outcome: The proposed module can be used to represent morphological resources on a unified basis.

Representing Compounding with OntoLex. An Evaluation of Vocabularies for Word Formation Resources (2024.lrec-main)

Copied to clipboard

Challenge: OntoLex is a de facto standard for the modelling of lexical resources in the framework of Linguistic Linked Open Data.
Approach: They propose to use OntoLex to convert Linked Open Data into compounds by using the RDF model.
Outcome: The proposed model can be applied to all resources harmonized in that format, potentially allowing for the conversion into Linked Open Data of a large amount of structured data.
Building a Morphological Treebank for German from a Linguistic Database (L18-1)

Challenge: German is a language with complex morphological processes.
Approach: They propose a morphological treebank for German based on a German morphology database and a Perl script for the generation.
Outcome: The proposed treebank is based on the German lexical database CELEX and is able to generate 40,000 morphological trees with a grade of detail that can be chosen according to the requirements of the applications.
A multilingual collection of CoNLL-U-compatible morphological lexicons (L18-1)

Challenge: The Universal Morphology project provides broad-coverage instantiated morphological inflection tables for hundreds of diverse languages.
Approach: They propose a language-independent feature schema for rich morphological annotation and a type-level resource of annotated data in diverse languages realizing that schema.
Outcome: The proposed schema has added 66 new languages, including 24 endangered languages.

Challenge: Explicit modeling of morphology has demonstrable benefits for language modeling, speech recognition, word embedding and keyword search.
Approach: They propose a language-independent feature schema for rich morphological annotation and a type-level resource for annotated data in diverse languages.
Outcome: The proposed schema has been improved to make it more complete and correct, and adds 66 new languages and parts of speech for 12 languages.
CoNLL-UL: Universal Morphological Lattices for Universal Dependency Parsing (L18-1)

Copied to clipboard

Challenge: Using the universal dependencies framework, we address the need for a universal representation of morphological analysis that can capture alternative morphology of surface tokens and is compatible with the segmentation and morphologic annotation guidelines prescribed for UD treebanks.
Approach: They propose a new annotation format for word lattices that represent morphological analyses and a resource that obeys this format for a range of typologically different languages.
Outcome: The proposed model can capture alternative morphological analyses of surface tokens and is compatible with the segmentation and morphology guidelines prescribed for UD treebanks.
