Resim paylaşım siteleri için etiket önerim yöntemleri

Due to the fast development of affordable digital cameras and the new trend ofsharing media through the web, large amounts of images have become availableon the Internet. Thus, at a time when a single site alone hosts over 4 billionphotos, the necessity of managing these massive numbers of photos for eff'cientand effective browsing/searching operations has increased.To properly organize large amounts of data, systems have been using collaborativetagging methods by assigning descriptive words, tags, to data andperforming text-based search and retrieval operations on these words. Unfortunately,due to various reasons, both the amount and quality of these tags assignedby users are low.In this work, we present and analyze two applications of tag expansion methodson photo-sharing websites. The purpose of these methods is to assist usersfor proper tagging at upload time. The goal of the approaches is not to give usersa complete set of tags that could be directly used but to give a list of, possibly,incomplete set of tags that would help or guide the users to tag in accordancewith the image content. With this assistance, problems such as incorrect taggingand insufficient tagging are expected to be solved.
