Reclaiming the Surigaonon Language: A Corpus-Based Approach
2 Research Collaborator, Computational Linguistics & Austronesian Studies
Surigaonon (ISO 639-3: sug), an indigenous Austronesian language of the Southern Visayan subgroup spoken across the Surigao provinces and Siargao Island, faces systemic domain contraction due to national educational centralization and commercial tourism pressures. This paper outlines the architecture and community-based deployment of the Halea Institute parallel corpora—a machine-readable, open-access bilingual repository combining 20th-century anthropological records (Garvan), maritime accounts (Florentino Das), and living oral oral histories collected across Siargao municipalities. By pairing syntactic corpus alignment with gamified pedagogical interfaces and youth scholarships, the project demonstrates how endangered language documentation can simultaneously serve linguistic computational analysis and vibrant generational reclamation.
1. Introduction & Sociolinguistic Context
The Surigaonon language constitutes one of the oldest attested Southern Visayan linguistic varieties, characterized by its distinctive phonological preservation of the voiced palatal affricate [dʒ] (represented orthographically as j or dj) in positions where neighboring Central Visayan (Cebuano) languages have shifted to the palatal glide [j]. Despite numbering hundreds of thousands of first-language speakers, the lack of standardized digital orthographies, instructional literature, and accredited curricula has historically relegated the language to informal domestic domains.
2. Corpus Architecture & Methodology
The Halea Corpus incorporates over 1,500 verified lexical roots, interlinear morphological glosses, and bilingual sentence alignments. Crucially, the parallel corpus distinguishes authentic vernacular morphology (such as the verbal prefix nag- rather than Cebuano naga-, and the past temporal adverb sauna rather than kaniadto) from external borrowing.
3. Pedagogical Integration & Results
By coupling digital corpora with gamified vocabulary engines (Buot Battle, Baruto Racer, Dayag Lubi) and in-person immersion modules on Siargao Island, the Halea framework bridges academic computational linguistics with grassroots learner retention.
