Description

A Universal Dependencies (UD) treebank for the dialect of Lesbos, a low-resource living Northern variety of Modern Greek. The treebank currently contains 625 sentences with manual annotations following the Universal Dependencies framework, representing the first UD treebank for a Northern Modern Greek dialect.

The Lesbos dialect belongs to the Northern Modern Greek dialect group, characterized by distinctive phonological features collectively known as “Northern vocalism.” These features include:

These features significantly distinguish the dialect of Lesbos from Southern dialects, including Standard Modern Greek (SMG). The dialect has been historically shaped by extensive contact with Italo-Romance (particularly Venetian) during 1355-1462 and Turkish during the Ottoman period (1462-1912), resulting in numerous loanwords and morphological elements. Unlike most Modern Greek dialects, Lesbian remains vital today, serving as the primary means of communication throughout the island.

This treebank represents the first Universal Dependencies resource for a Northern Modern Greek dialect.

Annotation Process

The treebank follows the UD annotation guidelines established for UD_Greek-GUD, complemented by grammatical descriptions and dialect dictionaries. Key annotation features include:

Tokenization

Lemmatization

Special Annotations

Data Sources

The corpus draws from six main sources representing different text types and dialectal variants from across Lesbos. The treebank consists of randomly shuffled sentences coming from these sources:

Dialectal Dictionaries (example sentences)

Contemporary Lesbian Literature

Oral Corpus (Field Research 2023–2024)

In addition to written sources, the dataset includes oral sentences transcribed from recordings collected during fieldwork conducted across multiple villages of Lesbos between 2023 and 2024. These recordings capture speakers of different ages and local varieties, reflecting the living use and intra-island variation of the dialect.
