Some previous studies (e.g. that carried out by Van Bruggen et al. in 2004) have pointed to a need for additional research in order to firmly establish the usefulness of LSA (latent semantic analysis) parameters for automatic evaluation of academic essays. The extreme variability in approaches to this technique makes it difficult to identify the most(More)

A study exploring texts at different academic levels. Abstract 26 27 In this study we propose an integrated method to automatically evaluate very brief 28 summaries (around 50 words) using the computational tool Latent Semantic Analysis 29 (LSA). The method proposed is based on a regression equation calculated with a corpus 30 of a hundred summaries (the(More)
The purpose of this article is to validate, through two empirical studies, a new method for automatic evaluation of written texts, called Inbuilt Rubric, based on the Latent Semantic Analysis (LSA) technique, which constitutes an innovative and distinct turn with respect to LSA application so far. In the first empirical study, evidence of the validity of(More)
In this paper, we present several proposals in order to improve the LSA tools to evaluate brief summaries (less than 50 words) of narrative and expository texts. First, we analyse the quality of six different methods assessing essays that have been widely employed before (Foltz et al., 2000). The second objective is to analyse how new algorithms inspired by(More)

The aim of this study was twofold. First, it describes school anxiety questionnaires, inventories, and scales developed and validated for children and adolescents, including School Anxiety Questionnaire, Inventory of School Fears, School Situations Survey, Visual Analogue Scale for Anxiety-Revised, Magallanes Scale Problem of Anxiety, and Anxiety School(More)
There is currently a widespread interest in indexing and extracting taxonomic information from large text collections. An example is the automatic categorization of informally written medical or psychological diagnoses, followed by the extraction of epidemiological information or even terms and structures needed to formulate guiding questions as an(More)
In the present study, we tested a computer-based procedure for assessing very concise summaries (50 words long) of two types of text (narrative and expository) using latent semantic analysis (LSA) in comparison with the judgments of four human experts. LSA was used to estimate semantic similarity using six different methods: four holistic (summary-text,(More)
