Visual Writing Prompts: Character-Grounded Story Generation with Curated Image Sequences
Current work on image-based story generation suffers from the fact that the
existing image sequence collections do not have coherent plots behind them. We
improve visual story generation by producing a new image-grounded dataset,
Visual Writing Prompts (VWP). VWP contains almost 2K selected sequences of
movie shots, each including 5-10 images. The image sequences are aligned with a
total of 12K stories which were collected via crowdsourcing given the image
sequences and a set of grounded characters from the corresponding image
sequence. Our new image sequence collection and filtering process has allowed
us to obtain stories that are more coherent and have more narrativity compared
to previous work. We also propose a character-based story generation model
driven by coherence as a strong baseline. Evaluations show that our generated
stories are more coherent, visually grounded, and have more narrativity than
stories generated with the current state-of-the-art model.Comment: Paper accepted by Transactions of the Association for Computational

Sources, Fate, and Impact of Microplastics in Aquatic Environment
Over the past decade, enhanced scientific interest has produced an expanding knowledge base for microplastics. The highest abundance of microplastics is typically associated with coastlines and oceans but the fate of these microplastics is elusive. Microplastics sink following fragmentation which is further ingested by marine biota thus imposes threat to them. Thus, the present review focuses on properties and sources of microplastics, its impact on environment, the bioaccumulation and trophic transfer of microplastics and its impact on living biota. This study would be helpful for the development and implementation of risk management strategies for managing the disposal of microplastics
