Indo-European Lexical Cognate Data from IELex

Lexical cognate data was exported from the Indo-European Lexical Database (IELex). The data supports research on language evolution and was used in a 2018 publication by Annemarie Verkerk. The dataset is associated with author Michael Dunn from Uppsala University.

Use Cases

• Train phylogenetic models of language evolution based on lexical cognate relationships.
• Analyze patterns of lexical change across Indo-European languages based on cognate data.
• Detect non-tree-like signal in language evolution using multiple tree topologies as referenced in the supporting publication.

Strengths

• Data originates from the established Indo-European Lexical Database (IELex).
• Associated with a peer-reviewed 2018 publication in the Journal of Historical Linguistics.
• Author is affiliated with Uppsala University, suggesting academic provenance.

Limitations

• Row count and file size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
