Resumen
Historically, schema matching has been studied a lot, but it still presents many difficulties
resulting from countless conflicts and problems. Approaches for NoSQL databases (Not
Only SQL) are still poorly studied, given that they have implicit schemes in their construction.
The increasing use of JSON (JavaScript Object Notation) documents shows the importance of
studies that can contribute to the manipulation of this type of document. This dissertation aims
to specify a process to match schemas for JSON documents. The process uses textual similarity
techniques (syntactic, semantics and radical extraction), diff algorithm, analysis of the hierarchical
element structure, and analysis of the instances contained in the documents. . These
techniques are applied in a combined manner to determine whether elements of JSON documents
are equivalent. The case study reported in this research shows accuracy and recall of
67.05% and 82.60%, respectively.
