Fig. 3: Example of the semantic parameters.
From: Semantic memory disorganization linked to social functioning in patients with schizophrenia
The figure illustrates an example of cosine similarity between adjacent words in a semantic fluency sequence. The number of switches was counted when the similarity between two consecutive words fell below a predefined threshold. Conversely, words were grouped within the same subcluster when the similarity between two consecutive words exceeded this threshold. Following this method, five semantic memory parameters (number of produced words, rank of the first switch, number of subclusters, number of switches, and largest cluster size) were calculated. Dashed line, threshold level of 0.235.
