La indización de artículos científicos con el sistema de indización automática SISA comparada con la indizaicón en las Bases de datos Agricola, WoS y SCOPUS

Since some years the generation of digital documents is enormous as well as its massive incorporation to the information systems and both realities seem unstoppable. Likewise, there is no doubt that indexing is one of the fundamental processes executed in documentary units. Although the first investigations in automatic indexing began decades ago this subject continues to raise interest. Since then different proposals and methodologies have been presented. SISA is a multilingual automatic indexing system for scientific articles based on heuristic and statistical principles governed by rules based on these principles. Objective. In this described context of constant digital increase, it is sought to know the SISA capabilities in the automatic indexing of articles in relation to how they do it in the Agricola, WOS and SCOPUS databases. Material and method. One hundred articles published in different years by the journal Agronomy for sustainable development were randomly selected, the indexing assigned to the articles in the mentioned databases was located, the documents were indexed with SISA, the different indexing were compared and they were calculated the consistency between Agricola and SISA
