Ο παγκόσμιος ιστός έχει εδραιωθεί πλέον ως το δημοφιλέστερο μέσο ανάκτησης πληροφοριών. Όπως είναι λογικό, όσο παλαιώνει τόσο μεγαλύτερη πληροφορία εμπεριέχει. Πληθαίνουν έτσι εκείνοι οι ιστότοποι που γιγαντώνονται άναρχα και ενώ σαν στόχο έχουν να προσφέρουν την πληροφορία στον χρήστη που τους επισκέπτεται, λόγω του τεράστιου όγκου της, κάνουν συχνά δύσκολη την πρόσβαση σε συγκεκριμένα κομμάτια αυτής. Με στόχο την αντιμετώπιση αυτής της κατάστασης, αναπτύσσονται τα τελευταία χρόνια αλγόριθμοι ανάθεσης υπερσυνδέσμων σε ιστοτόπους. Η λογική τους είναι ο εντοπισμός της πιο δημοφιλούς ή πιθανής πληροφορίας και η εξασφάλιση καλύτερης πρόσβασης σε αυτήν, αναθέτοντας υπερσυνδέσμους (hotlinks) προς τις ιστοσελίδες που την περιέχουν. Οι αλγόριθμοι αυτοί εφαρμόζονται όχι σε πραγματικές αναπαραστάσεις ιστοτόπων, αλλά κατά κανόνα στα αντίστοιχα κατευθυνόμενα άκυκλα γραφήματα (DAG) αυτών. Όπως είναι γνωστό κανένας ιστότοπος δεν έχει μορφή DAG, με συνέπεια να υπάρχει μία απόσταση από τη θεωρητική ανεύρεση υπερσυνδέσμων και την πιθανή εφαρμογή τους στην πραγματικότητα. Σε αυτήν την εργασία ασχολούμαστε αρχικά με την μεθοδική καταγραφή της πραγματικής συνδεσμολογίας ενός ιστότοπου, που αποτελεί ένα πρώτο βήμα στην ανάθεση υπερσυνδέσμων σε πραγματικούς ιστοτόπους. Αυτό επιτυγχάνεται με την κατάλληλη προδιαγραφή και υλοποίηση μιας δικτυακής μηχανής αναζήτησης, ώστε να ανταποκρίνεται στις ανάγκες μας. Προτείνουμε στη συνέχεια το εργαλείο ‘HotLink Visualizer’, το οποίο αρχικά μετατρέπει την πληροφορία της συνδεσμολογίας ενός ιστοτόπου σε απλά δεδομένα μορφής πίνακα και στη συνέχεια οπτικοποιεί το αποτέλεσμα. Τέλος, υλοποιεί την απευθείας ανάθεση υπερσυνδέσμων προσθέτοντας αυτόματα μέσα στις σελίδες του ιστοτόπου τους υπερσυνδέσμους και οπτικοποιεί εκ νέου το αποτέλεσμα. Παρέχει έτσι τη δυνατότητα διατήρησης διαφορετικών εκδόσεων της μορφής ενός ιστοτόπου, ανάλογα με το σύνολο από υπερσυνδέσμους που έχουν ανατεθεί σε αυτό. / The World Wide Web has become established as the most popular source of information retrieval. As expected, the older it gets the more information it contains and thus the number of the web sites with gigantic growth and bad information access rates is constantly increased within it. During the last years the matter is being addressed with the development of several hotlink assignment algorithms for web sites. The main idea behind those algorithms is to spot the most popular or more likely to be accessed piece of information and provide better access to it by assigning links (hotlinks) to the web pages containing it. These algorithms are not applied to the actual representations of these web sites but usually to their corresponding direct acyclic graphs (DAGs). However, it is widely known that a web site in its true form is not a DAG, since there can be found hundreds of links pointing to just one page. Hence, there is a gap between the theoretical determination of a set of hotlinks and the possible application of this set to a real web site. In this paper we first address the issue of recording and persisting the exact map of a web site with its full connectivity, which can be considered as a first step towards the assignment of hotlinks in real web sites. We succeed in that, with the appropriate specification and implementation of a web crawler, with functionality suited to our specific needs. We then propose an administrative tool, the ‘Hotlink Visualizer’, which, after persisting in tabular data all the necessary information to capture a web site’s real map, visualizes the outcome and implements hotlink additions by adding with an automated procedure the generated hotlinks in the web pages of the site. Thus we have the ability to maintain in row data different forms and versions of the originally parsed web site, as it can be formed from the assignment of different hotlink sets to it.
