“…This gives us considerable flexibility for clustering various types of data, for which the 'natural' dissimilarity measure may not be a metric (see, e.g. [8] for example of dissimilarity measures derived for categorical data). We present here some examples for which the 'natural' dissimilarity measure is an informational divergence.…”

“…4) Mean Distance of Brother Nodes (mdisbr): the mean distance of a specific node from its Brother Nodes. The distance of two nodes d(x,y) is calculated using the dissimilarity measure presented in (Boutsinas and Papastergiou, 2008). The dissimilarity between any two attribute values is repesented by the distance between the corresponding nodes of the tree structure as defined by the following formula:…”

“…Όπως είναι φυσικό, μια τεχνική μελωδικού τεμαχισμού [6] θα μπορούσε να χρησιμοποιηθεί με σκοπό να εξασφαλίσει εισαγόμενες εγγραφές (input records). Παρόλα αυτά, είναι αλήθεια ότι δεν υπάρχει ένας μοναδικός σωστός τεμαχισμός ενός μουσικού κομματιού.…”

“…Τέλος, υπάρχουν επίσης ποικίλα άλλα μέτρα ομοιότητας που χρησιμοποιούνται στην ομαδοποίηση και εφαρμόζονται σε δομημένα δεδομένα, (βλέπε [6] για μία επισκόπηση αυτών), π.χ. δεδομένα δομημένα σε μορφή δένδρου, τα οποία δεν φαίνεται, από όσο συμπεράναμε, να συνεισφέρουν σημαντικά στην ομοιότητα μουσικών μοτίβων.…”
