The CoViStories workshop seeks contributions in the area of visual story creation, with collaborative videos, images and texts available from professional media and social-media users. The challenges in creating such visual timelines are various: alignment of videos and images through sound or timestamps, detection of video intervals of high interest, caption generation for a group of pictures, among others. Contributions in the following topics are expected:

• Analysis and verification of collaborative visual content: the visual understanding of individual images or groups of related images provides strong relevance indicators with respect to the final visual story. Moreover, detecting the reliability of such visual content is critical to ensure the truth of the story. Specific topics:

a. Image concept detection

b. Collaborative event-episodes annotation

c. Visual forensics

• Temporal aspects of stories: the temporal aspects and relations extracted from visual content are key to conveying coherent, sequential storytelling. Specific topics:

a. Collaborative event-episodes detection

b. Temporal and semantic media alignment

c. Information freshness

d. Multimodal event timelines

• Qualitative and perceptual aspects: are often a decisive factor in the selection of the best images and videos that can tell a story. Specific topics:

a. Event summary diversity

b. QoE in visual summaries

c. Affect and emotion in visual summaries and caption generation

• Collaborative visual summaries: the creation of visual summaries and their descriptions are the ultimate goal, building on the previous topics. Specific topics:

a. Multimodal caption generation

b. Collaborative media summaries

c. Non-linear and multiple view summarization

• User studies: we also encourage ideas about how to evaluate visual user experiences in terms of visual coherence, visual composition, story comprehensiveness and other aspects related to the creation of visual summaries from both professional and social-media content.
• Applications: collective contributions of images and videos concerning a particular event can be found in many domains. Social-media applications, family photo albums, historical photo libraries, patient’s clinical history, are some of the examples.

 We will accept contributions as full-papers and position-papers on the above topics. Submissions are limited to 6 pages.
