Project: CLDF: Cross-Linguistic Data Formats

The amount of available digital data for the languages of the world is constantly increasing. Unfortunately, most of the digital data are provided in a large variety of formats and therefore not amenable for comparison and re-use. The Cross-Linguistic Data Formats initiative proposes new standards for two basic types of data in historical and typological language comparison (word lists, structural datasets) and a framework to incorporate more data types (e.g. parallel texts, and dictionaries). The new specification for cross-linguistic data formats comes along with a software package for validation and manipulation, a basic ontology which links to more general frameworks, and usage examples of best practices.
Publications from this Project:
the past decades have seen substantial growth in digital data on the world’s languages. at the same time, the demand for cross-linguistic datasets has been increasing, as witnessed by numerous studies devoted to diverse questions on human prehistory, cultural evolution, and human cognition. Unfortunately, most published datasets lack standardization which makes their comparison difficult. Here, we present a new approach to increase the comparability of cross-linguistic lexical data. We have designed workflows for the computer-assisted lifting of datasets to Cross-Linguistic Data Formats, a …
Abstract PDF 10.1038/s41597-022-01432-0Computational phylogenetics is a relatively recent branch of historical linguistics that uses quantitative techniques to investigate the history of related languages. As the classical comparative method is less explicit on the techniques for constructing phylogenies of language families (see discussion in Jacques & List 2019), such a new approach can complement traditional techniques for sub-grouping based on shared innovations (Ross & Durie 1996).
