Announcement (English)

Announcing AthDGC ("Athens-PROIEL (the dependency-treebank (a collection of sentences whose grammatical structure has been analysed and stored) standard for early Indo-European languages, developed at Oslo)"), an open platform of computational tools and a diachronic Greek treebank, with Indo-European parallels. AthDGC provides two open deliverables side by side: an open-source toolkit for diachronic linguistics (LightSIDE (an open-source text-mining workbench developed at Carnegie Mellon)-AthDGC (the Lavidas-extension fork of LightSIDE that operates on syntactic features rather than only text features) for PROIEL syntactic features, a NoSketch-style concordancer (a search tool that shows every occurrence of a word in its surrounding context), fine-tuned (further trained on new data to adapt it to a particular text type) Stanza (Stanford's open-source Python workflow that automatically tags, lemmatises, and parses sentences) checkpoints (saved snapshots of a trained model), a per-verb argument-structure extractor, a cross-lingual alignment (matching corresponding words or sentences between texts in different languages) viewer, a corpus-fix toolkit, a retranslation-pair browser, a retelling-chain explorer, a PROIEL XML 2.0 (the file format that stores each sentence as a tree of word-by-word grammatical relations, developed at Oslo) validator) and a PROIEL XML 2.0 treebank with cross-lingual NT alignment. The platform ingests, dependency-parses, and cross-lingually aligns the entire Greek language, from Homer to Modern Greek, at the National and Kapodistrian University of Athens (NKUA). Every sentence carries full PROIEL-style argument-structure annotation; the NT cross-aligned backbone aligns Greek to Latin (Vulgate), Gothic (Wulfila), and Old Church Slavonic (Marianus). Focus: retranslations, retellings, and influential texts across three millennia. Every source text is open-access (Perseus, OGL/First1K, SBL GNT, Rahlfs LXX, Papyri.info, Patrologia Graeca via Documenta Catholica Omnia, TITUS, GRETIL, SARIT, Wulfila Project, National Library of Ukraine); the annotation layer is AthDGC-original under CC-BY-4.0 (the Creative Commons Attribution 4.0 licence, which permits reuse with credit).

Current state: eight diachronic Greek periods (Archaic through Modern), with NT-verse cross-alignment to Latin Vulgate, Gothic Wulfila, OCS Marianus, and Classical Armenian (in ingestion); Sanskrit, Old English, Avestan, Old Persian, and Ukrainian queued at v0.7. Verified per-witness counts will be included with the v0.5 release notes after the ARIS audit pass.
