Frecuencia y dispersión léxicas en textos médicos divulgativos en español

We analyse frequency, dispersion and usage of lexical categories (nouns, adjectives, verbs, eponyms and adverbs ending in -- mente) in 363 medicine popularisation texts in Spanish (334690 words). We propose the concept of linear dispersion, which is suitable for analysing homogeneous corpora without different subsections. Results indicate that the most commonly used words do not have medical meanings, excepting nouns. In addition, words in the lowest ranks are heavily dependent on the contents of each text. Nouns and adjectives show the highest lexical richness (more different lemmas), which is related to the informative nature of the corpus. The article includes an appendix with the most used lemmas that may be useful for professionals working in this domain.
