The Infrastructure behind Latvian National Corpora Collection

Roberts Dargis, Baiba Valkovska


Abstract
The rapid advancement of digital humanities and Natural Language Processing (NLP) necessitates centralized access to high-quality, large-scale language resources. This paper presents the technical infrastructure and evolving ecosystem of Korpuss.lv, the central access platform for the Latvian National Corpora Collection (LNCC). The LNCC consolidates 42 corpora developed by 14 institutions, comprising 2.8 billion tokens of written and spoken Latvian across diverse genres and annotation layers. Korpuss.lv has evolved from a simple metadata index into a comprehensive digital infrastructure that enhances corpus discoverability, accessibility, and usability for researchers in linguistics, digital humanities, and natural language processing. The platform integrates noSketchEngine as its primary corpus analysis tool and extends its functionality with custom modules, including a metadata-driven Corpora Explorer, a client-side Federated Content Search system, and precomputed UD-based Word Sketches. The ecosystem is further supported by CLARIN DSpace repositories for persistent storage and citation management, as well as a federated academic authentication architecture built on SATOSA and Keycloak via the CLARIN Service Provider Federation. The paper outlines architectural decisions, integration strategies, and future development plans.
