The primary outcome measure used in most word retrieval treatment studies in aphasia has been percent improvement in oral picture naming, a measure of language functions (WHO, 2001). Test-retest reliability is as important for measures used to evaluate impairments as it is for those that measure change, since measures that are not stable will not provide valid or reliable assessments of impairments. An average effect size was calculated for each participant and an overall average was determined for all participants as a group. Several measures available in the CLAN System can be used to assess word retrieval difficulty. In binary classification, precision is analogous to positive predictive value. (4) Retrieval difficulties on tests of single-word production would be associated with measures of word retrieval in connected speech. Tf-idf stands for term frequency-inverse document frequency, and the tf-idf weight is a weight often used in information retrieval and text mining.This weight is a statistical measure used to evaluate how important a word is to a document in a collection or corpus.
