A Case-based reasoning approach to validate grammatical gender and number agreement in Spanish language

Across Latin America 420 indigenous languages are spoken. Spanish is considered a second language in indigenous communities and is progressively introduced in education. However, most of the tools to support teaching processes of a second language have been developed for the most common languages such as English, French, German, Italian, etc. As a result, only a small amount of learning objects and authoring tools have been developed for indigenous people considering the specific needs of their population. This paper introduces Multilingual–Tiny as a web authoring tool to support the virtual experience of indigenous students and teachers when they are creating learning objects in indigenous languages or in Spanish language, in particular, when they have to deal with the grammatical structures of Spanish. Multilingual–Tiny has a module based on the Case-based Reasoning technique to provide recommendations in real time when teachers and students write texts in Spanish. An experiment was performed in order to compare some local similarity functions to retrieve cases from the case library taking into account the grammatical structures. As a result we found the similarity function with the best performance

Aprendizaje léxico y desarrollo de la gramática: vocabulario verbal, aceleración morfológica y complejidad sintáctica

This paper studies the initial development of certain language components. More precisely, we analyse the relation between three aspects that are closely involved in the grammar of the verb: morphological productivity, syntactic complexity, and verb vocabulary learning. The study is based on data about the relationship between lexical development and grammatical development, and also on proposals that a critical mass of vocabulary is needed in order to develop a grammatical component. The sample comprised six subjects who are monolingual or bilingual in Catalan andlor Spanish. Results show a morphological spurt some time afer the learning of a certain quantity of verbs. Moreover, syntactic complexity is only evident some months after this morphological spurt

La productividad de la morfología verbal a los años dos años de edad

Este trabajo se centra en estudiar la adquisición de la morfología verbal en una lengua con un paradigma verbal morfológicamente rico. Se predice que los niños de dos años no mostrarán productividad morfológica ante verbos desconocidos. La muestra se compone de 12 sujetos de edades comprendidas entre los 22 y los 31 meses. El procedimiento, de tipo experimental, se caracteriza por entrenar a los niños con verbos inventados. Los resultados muestran que los sujetos solamente utilizan los nuevos verbos con la forma morfológica con la que se han presentado. También se observa la omisión de determinados constituyentes de la oración. Estos resultados se discuten en relación con la asunción de discontinuidad de las competencias lingüísticas infantiles
