Documentary Evidence Mapping for the Redesign of Employment Certificates

Resumen

This short contribution organizes documentary evidence to inform the redesign of employment certificate issuance at the Universidad Nacional de Chimborazo. The team identified a process with manual steps, time consumption, and no verifiable issuance record. The study combined a corpus of 19 sources with an inventory of 16 files. An AI-assisted ETL procedure generated a star model in five CSV files, later consolidated in Excel and a dashboard. Textual analysis used word clouds, n-grams, the Jaccard index, and a co-occurrence network. The model recorded 8 frameworks and 51 mentions: process management occurred in 11 documents and ISO 15489 in 10, while four frameworks had no mentions. These results do not establish operational effectiveness; they identify documentary references and gaps that should be checked before institutional implementation.
