The Invalsi data Set

Description

The INVALSI "Istituto nazionale per la valutazione del sistema educativo di istruzione e di formazione" data set is a subset of 15398 tweets from the original data collected during the days of the administration of a national test to secondary school children in Italy (from May 6th to June 18th, 2014). The INVALSI data set includes only tweets that include the word or the hashtag INVALSI. Unfortunately, Twitter policies do not allow for the distribution of the original data, and the original IDs where lost, but this R version provides the Document-Term matrix which is enough for the text-ming task.

Usage

data(invalsi)

Examples

data(invalsi)
S <- invalsi$S # iSA feature vectors
dtm <- invalsi$dtm  # DocumentTerm matrix
dim(dtm)
table(tr)  # the hand coded data tags
