Why do people tag? Users have mostly avoided annotating media such as photos -- both in desktop and mobile environments -- despite the many potential uses for annotations, including recall and retrieval. We investigate the incentives for annotation in Flickr, a popular web-based photo-sharing system, and ZoneTag, a cameraphone photo capture and annotation tool that uploads images to Flickr. In Flickr, annotation (as textual tags) serves both personal and social purposes, increasing incentives… 
Flickr tag recommendation based on collective knowledge
TLDR
This paper analyzes a representative snapshot of Flickr and presents and evaluates tag recommendation strategies to support the user in the photo annotation task by recommending a set of tags that can be added to the photo.
Motivations for image publishing and tagging on flickr
TLDR
Investigating people’s motivations for image publishing and tagging on the web 2.0 site Flickr found that social organisation and social communication are the most popular motivational factors for both using Flickr and for tagging images, suggesting that Flickr is enjoyed for the community environment it provides rather than as a place to store images.
Motivations and intentions of flickr users in enriching flick records for library of congress photos
TLDR
It is revealed that affective or emotional reactions play a critical role in the use of social tagging of institutional collections by comparing the findings to existing frameworks for tagging motivations.
What drives content tagging: the case of photos on Flickr
TLDR
This work examines tagging behavior on Flickr, a public photo-sharing website, and finds that the levels of the Self and Public motivations, together with social presence indicators, are positively correlated with tagging level.
Exploiting User-supplied Tags for Flickr Photos Annotation
TLDR
This paper proposes an approach to automatically annotate Flickr photos by exploiting user-supplied tags, and combines top ranked initial tags with expanding tags to construct final annotations.
Why do people tag?
TLDR
The strength of relationships between several motivations and users' tagging levels on Flickr, a prominent Web 2.0 photo sharing community, is studied, to understand what underlies tagging and to measure the degree to which different motivations affect tagging activity.
Why People Tag? Motivations for Content Tagging
Tagging, or using keywords to annotate images, bookmarks, and blogs, is gaining much popularity. Since tagging is seen as an important change in the way images are organized and shared, we need to
Tag suggestion on youtube by personalizing content-based auto-annotation
TLDR
A novel approach is suggested that integrates the strengths of history-based tag suggestion with a content matching crowd-sourced from a large repository of user generated videos and performs a visual similarity matching and merges neighbors found in a large-scale reference dataset of user-tagged content with others from the user's personal history.
Social Image Tagging With Diverse Semantics
TLDR
This paper proposes an approach to retag social images with diverse semantics where both the relevance of a tag to image as well as its semantic compensations to the already determined tags are fused to determine the final tag list for a given image.
Tagging tagged images: on the impact of existing annotations on image tagging
TLDR
This study explores the relationship between tag quality/quantity and completeness degree by conducting a study on a set of human crowdsourcing annotators over a collection of images with different completeness degrees, and shows a significant relation between completeness and image tagging.

Motivating Annotation for Personal Digital Photo Libraries : Lowering Barriers While Raising Incentives
The value of personal digital photo libraries grows immensely when users invest effort to annotate their photos. Frameworks for understanding annotation requirements could guide improved strategies
Leveraging context to resolve identity in photo albums
TLDR
The system suggests likely identity labels for photographs in a personal photo collection that leverages automatically available context, like the time and location where the photos were taken, to generate label suggestions for identities that were not yet annotated.
HT06, tagging paper, taxonomy, Flickr, academic article, to read
TLDR
A model of tagging systems, specifically in the context of web-based systems, is offered to help illustrate the possible benefits of these tools and a simple taxonomy of incentives and contribution models is provided to inform potential evaluative frameworks.
Direct annotation: a drag-and-drop strategy for labeling photos

  • 2000
TLDR
The user interface design and the database schema are described to support direct annotation, as implemented in the PhotoFinder prototype, which can make the task faster, easier and more appealing.
From Where to What: Metadata Sharing for Digital Photographs with Geographic Coordinates
TLDR
The results show that the LOCALE system performs search tasks with surprising accuracy, even when searching for specific landmarks.
Semi-Automatic Image Annotation
TLDR
A novel approach to semi-automatically and progressively annotating images with keywords is presented, and a preliminary user study is described showing that users view annotations as important and will likely use them in image retrieval.
Collective creation and sense-making of mobile media
TLDR
A messaging application for camera phones with the aim of supporting spectator groups at large-scale events with the idea of collectively created albums called Media Stories, which indicates the centrality of collocated viewing and creation in the use of media.
Understanding photowork
TLDR
The notion of "photowork" is introduced as the activities people perform with their digital photos after cap-ture but prior to end use such as sharing, and how "search" as it is usually defined may have much less relevance than new ways of browsing for the design of new digital photo tools.
Simplifying the Management of Large Photo Collections
TLDR
This application combines a light table for showing thumbnails of the entire photo collection with a tree view that supports navigating, sorting, and filtering photos by categories such as dates, events, people, and locations.
How do people manage their digital photographs?
TLDR
The results suggest that participants found their digital photos much easier to manage than their non-digital ones, but that this advantage was almost entirely due to the simple browsing features of Shoebox.
