An Overview of Flickr Challenges and Research Opportunities

Abstract

Abstract-It is rather true that nowadays diversity and a potential for growth characterize the field of popular social networks like Flickr. Based on this observation, we provide herein a brief overview of the basic characteristics, challenges and research opportunities of the latter. Some historical facts of its origin are presented, followed by a review of its digital photo sharing and tagging capabilities, focusing on the most popular related research fields, like travel applications, knowledge extraction and human activity tracking. Throughout the paper the status of current research and directions for future research are highlighted in an effort to provide useful information to fellow researchers.

Image Tag Recommendation based on Ranked Categorical Nearest Neighbors and Weighted Tag Features

“…Many times, users assign tags that are imprecise and irrelevant to the image. According to the survey, only 50% of the Flickr tags describe the content of the images [1]. The presence of irrelevant tags affects the performance of the classification and image retrieval system.…”

In text 1 based image retrieval approach, the images are retrieved using text query and texts around the images. In content based image retrieval approach, visual similarity is identified between input image and images stored in the database.…”

“…The Flickr is a well-known website owned by Yahoo! [1]. It is used as a virtual community for image based information sharing and is less motivated with commercial gains.…”
