Evaluación de resúmenes de textos narativos y expositivos utilizando Análisis Semántico Latente

the objective of this study is to identify a method for the automatic evaluation of the summaries developed from narrative and expository spanish texts. in order to fulfill this task evaluation of 373 summaries carried out by three teachers is correlated with the results delivered by latent semantic analysis. scores assigned by the latent semantic analysis are obtained through three methods: 1) comparison of the summaries with the source text, 2) comparison of the summaries with a consensuated one, 3) comparison of the summaries with three summaries developed by three evaluators. the most relevant results include: a) a high correlation between assessments by the evaluators (:0.63), b) a high correlation between the computational methods used (:0.62) and c) a positive medium-high average correlation between assessments undertaken by the teachers and the latent semantic analysis in the second and third method (;0.53 in both cases and types of texts). both methods presented greater average correlation with testers when the texts evaluated were predominantly narratives (;0.59 and 0.45 respectively).
