eCare Web Corpus: Companion Website

Go back to the eCare@home project website

Last Updated: 11 Sept 2017

In this website we present and document the progress of the eCareCorpus. From this page you can download the corpus, the datasets, the R scripts and the outputs of the machine learning models that we have used for the lay-specialized text classification task.


The project and the corpus are described in the following paper: Santini M., Jonsson A., Nystrom M. and Alirezai M. (2017) Web Corpus for eCare: Collection, Lay Annotation and Learning. First Results. Proceedings of LTA'17, FedCSIS 2017, Prague. Position paper (pdf). Slides (pdf).

Medical Terms a.k.a. "seeds"

A "seed" is a medical term that has been used as keyword in the search engine to retrieve documents about a disease. For the eCare web corpus, we have used only medical terms representing chronic diseases.

# initial seeds # retrieved seeds # bootcatted web doc. # web doc. per retrieved seeds: Mean # web doc. per retrieved seeds: Median # web doc. per retrieved seeds: SDev

Wordcounts per Subcorpus

The eCare web corpus contains 155 subcorpora. Each subcorpus includes the documents that have been retrieved and downloaded for each seed.
