From session tape to semiotic graph
Details
Challenge
Mito Editorial, an independent Buenos Aires publisher behind RPG systems like Leyenda, needed a research-grade visualization instrument for doctoral work analyzing tabletop role-playing campaigns as semiotic systems. The analysis demanded tracking meaning across three simultaneous levels — micro-level turn-by-turn interaction, meso-level emergent narrative, and macro-level ontological infrastructure — across hours of video, thousands of annotated transcript boxes, and a growing knowledge graph of fictional and real-world entities. No existing tool could hold all three levels together with synchronized video playback, structured coding, and a browsable ontology aligned to CIDOC-CRM. The instrument had to be built from scratch, and it had to evolve alongside the research itself.
Approach
Designed and built the full platform as a single-page application on React 19 and TypeScript, backed by Neon serverless Postgres with direct SQL over HTTP — no ORM, no REST API. The interface synchronizes video playback with a 20-column transcript analysis model, three-mode timelines with row-packing overlap detection and contiguous pill merging, and a Cytoscape.js force-directed graph representing a GOLEM ontology aligned to CIDOC-CRM. Built a domain-filtered narrative layer with assertoric sourcing, a ubiquitous language glossary with provenance tracking, and a React Admin back-office for 25 entity types. Delivered bilingual (EN/ES) with guided tours, inline editing across all levels, PDF presentation viewer with synchronized page timelines, and analytics event tracking throughout.
