It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum'

MentorChat has been developed as a domain-independent dialogue system that (a) promotes constructive peer interactions using facilitative agent interventions (prompts), and (b) enables the teacher to configure the support provided by the conversational agent.
MentorChat can support discussions in English or Greek, and was implemented using modern web technologies, such as HTML5, CSS3 and AJAX. The system infrastructure is based on a client-server model, which allocates workloads between the server and the clients. Its architecture comprises three main modules: the student, the teacher and the conversational agent module.
The conversational agent of MentorChat is based upon the following three models:
 The peer interaction model, which records and stores the students’ interactions in a computational format.
 The domain model, which utilizes the teacher’s domain knowledge representation in conjunction with the pattern matching algorithms to determine whether an agent intervention would be appropriate.
 The intervention model, which examines a series of various micro- parameters (e.g. the time passed since the last agent intervention) to determine if an intervention will eventually be displayed.

Το MentorChat είναι ένα πρωτότυπο σύστημα υποστήριξης της συνεργασίας που εστιάζει στη χρήση ευέλικτων διαλογικών πρακτόρων με στόχο την υποστήριξη της συνεργασίας και τη δημιουργία πρόσφορων συνθηκών παραγωγικού διαλόγου μεταξύ των εκπαιδευομένων.
Το MentorChat αναπτύχθηκε ως ένα διαδικτυακό εργαλείο που επιτρέπει στον εκπαιδευτικό/ερευνητή να οργανώσει μια συνεργατική εκπαιδευτική δραστηριότητα και να παραμετροποιήσει τις παρεμβάσεις του διαλογικού πράκτορα. Για την υλοποίηση του MentorChat χρησιμοποιήθηκαν οι γλώσσες προγραμματισμού HTML5, CSS3, AJAX, PHP και MySQL. Το MentorChat μπορεί αυτή τη στιγμή να υποστηρίξει δραστηριότητες τόσο στην Ελληνική όσο και στην Αγγλική γλώσσα. Η αρχιτεκτονική του βασίζεται στο μοντέλο του «πελάτη-εξυπηρετητή» που επιτρέπει στο σύστημα να λειτουργήσει αποδοτικά για πολλαπλές ομάδες επιμορφούμενων που εργάζονται ταυτόχρονα σε πραγματικό χρόνο. Αυτό γίνεται εφικτό κατανέμοντας τις εργασίες του συστήματος μεταξύ του εξυπηρετητή και των χρηστών. Η αρχιτεκτονική του MentorChat παρουσιάζεται στην Εικόνα 1.
Χρησιμοποιώντας το MentorChat οι επιμορφούμενοι μπορούν να συνδεθούν στο σύστημα για να συμμετέχουν σε μια σύγχρονη συνεργατική δραστηριότητα που βασίζεται σε ανταλλαγή γραπτών μηνυμάτων (text-based chatting). Μια δραστηριότητα μπορεί να περιλαμβάνει πολλές φάσεις, κάθε μία από τις οποίες αφορά ένα διαφορετικό θέμα συζήτησης (Εικόνα 2, Α). Σε κάθε φάση οι ομάδες μαθητών καλούνται να συζητήσουν και να δώσουν μια κοινή απάντηση στο ερώτημα που τους έχει τεθεί για τη συγκεκριμένη φάση. Οι επιμορφούμενοι μπορούν να συνομιλήσουν πληκτρολογώντας και ανταλλάσσοντας γραπτά μηνύματα ή χρησιμοποιώντας την λειτουργία «αναγνώρισης φωνής» για τη συγγραφή και αποστολή των μηνυμάτων μέσω φωνής (Εικόνα 2, Β).
Κατά τη διάρκεια της συνομιλίας των μαθητών ένας διαλογικός πράκτορας μπορεί να παρέμβει εμφανίζοντας (και διαβάζοντας) ερωτήσεις που σχετίζονται με το τρέχων θέμα συζήτησης και έχουν ως στόχο να «πυροδοτήσουν» το διάλογο των μαθητών γύρω από σημαντικές έννοιες του γνωστικού αντικειμένου της δραστηριότητας. Ο εικονικός πράκτορας στο περιβάλλον του MentorChat διαθέτει μια δυσδιάστατη ανθρωπομορφική αναπαράσταση (Εικόνα 2, Γ) ενώ τα μηνύματα του εμφανίζονται έξω (αριστερά) από το κεντρικό παράθυρο ανταλλαγής μηνυμάτων των επιμορφούμενων (Εικόνα 2, Δ). Η συγκεκριμένη στρατηγική σχεδίασης διατηρεί το μήνυμα του πράκτορα σε μόνιμα ορατό σημείο προσφέροντας τη δυνατότητα απάντησης όποτε οι επιμορφούμενοι το επιθυμούν.
Ένας εκπαιδευτικός μπορεί να χρησιμοποιήσει το MentorChat για να δημιουργήσει μια συνεργατική μαθησιακή δραστηριότητα όπου οι μαθητές θα κληθούν να συζητήσουν και επιλύσουν μία σειρά από εργασίες. Κατά τη δημιουργία μιας εκπαιδευτικής δραστηριότητας, η διεπαφή του συστήματος που αφορά τον εκπαιδευτικό επιτρέπει τις εξής λειτουργίες: (α) την διαχείριση των συμμετεχόντων καθώς και των ομάδων, (β) την εισαγωγή των ερωτημάτων/θεμάτων που αντιστοιχούν στις διαφορετικές φάσεις συζήτησης της δραστηριότητας, (γ) την ζωντανή παρακολούθηση των συνομιλιών όλων των ομάδων και (δ) την διαμόρφωση του γνωστικού μοντέλου που προσδιορίζει τις παρεμβάσεις του πράκτορα για τη συγκεκριμένη δραστηριότητα.
Για τον καθορισμό του γνωστικού μοντέλου ο εκπαιδευτικός καλείται να εισάγει μία λίστα από έννοιες (λέξεις ή φράσεις) κλειδιά. Αξιοποιώντας τις έννοιες αυτές, τους αλγορίθμους αναγνώρισης όμοιων συμβολοσειρών καθώς και τα διαθέσιμα λεξικά του συστήματος, ο πράκτορας είναι σε θέση να αντιληφθεί το τρέχων θέμα συζήτησης και να συνθέσει δυναμικά τις παρεμβάσεις του. Οι παρεμβάσεις αυτές προέρχονται από τη θεωρία του «Ακαδημαϊκά Παραγωγικού Διαλόγου» καλώντας τον επιμορφούμενο είτε να εξωτερικεύσει το συλλογισμό του γύρω από κάποια έννοια κλειδί (π.χ. «Γιατί πιστεύεις πως το Χ είναι σημαντικό;») είτε να επιχειρηματολογήσει σε σχέση με τον συλλογισμό που έχει εκφράσει ο συνεργάτης του (π.χ. «Συμφωνείς ή διαφωνείς με όσα είπε ο συνεργάτης σου για το Χ; Γιατί;»).
