    Στόχοι

    Στόχος είναι η μελέτη, ανάλυση και εξόρυξη γνώσης από τον παγκόσμιο ιστό αλλά και τα κοινωνικά δίκτυα. Το μάθημα θα κινηθεί σε δύο άξονες την ανάλυση δικτύων και την εξόρυξη γνώσης από το web. Ο πρώτος άξονας εστιάζεται στη μέτρηση, ανάλυση και απεικόνιση των σχέσεων και των ροών ανάμεσα στις οντότητες που συμμετέχουν σε ένα δίκτυο με έμφαση στις ιδιότητες και εφαρμογές στον παγκόσμιο ιστό και τα κοινωνικά δίκτυα. Στο πλαίσιο της εξόρυξης γνώσης από τον ιστό, θα γίνει μελέτη μεθόδων και εργαλείων για την εξόρυξη γνώσης τόσο από το περιεχόμενο, τη δομή αλλά και τα δεδομένα χρήσης του παγκόσμιου ιστού με έμφαση στην διαχείριση μη σχεσιακών δεδομένων, όπως ήμι-δομημένα με μορφή γραφημάτων ή και αδόμητα όπως το κείμενο.

    Δεξιότητες

    Χρήση εργαλείων εξόρυξης γνώσης από δεδομένα και ανάλυσης δεδομένων όπως Python (NetworkX) και Rapidminer, και εργαλείων διαχείρισης και  οπτικοποίησης γραφημάτων όπως Neo4j , Pajekκαι Gephi.
