WITH THE RAPID GROWTH OF THE INTERNET AND THE SPREAD OF THE INFORMATION CONTAINED THEREIN, THE VOLUME OF INFORMATION AVAILABLE ON THE WEB IS MORE THAN THE ABILITY OF USERS TO MANAGE, CAPTURE AND KEEP THE INFORMATION UP TO DATE. ONE SOLUTION TO THIS PROBLEM ARE PERSONALIZATION AND Recommender systemS. Recommender systemS USE THE COMMENTS OF THE GROUP OF USERS SO THAT, TO HELP PEOPLE IN THAT GROUP MORE EFFECTIVELY TO IDENTIFY THEIR FAVORITE ITEMS FROM A HUGE SET OF CHOICES.IN RECENT YEARS, THE WEB HAS SEEN VERY STRONG GROWTH IN THE USE OF BLOGS. CONSIDERING THE HIGH VOLUME OF INFORMATION IN BLOGS, BLOGGERS ARE IN TROUBLE TO FIND THE DESIRED INFORMATION AND FIND BLOGS WITH SIMILAR THOUGHTS AND DESIRES. THEREFORE, CONSIDERING THE MASS OF INFORMATION FOR THE BLOGS, A BLOG Recommender system SEEMS TO BE NECESSARY.IN THIS PAPER, BY COMBINING DIFFERENT METHODS OF CLUSTERING AND COLLABORATIVE FILTERING, PERSONALIZED Recommender system FOR PERSIAN BLOGS IS SUGGESTED.
