# Cats and Captions vs. Creators and the Clock #### Comparing multimodal content to context in predicting relative popularity [Jack Hessel](https://www.cs.cornell.edu/~jhessel), [Lillian Lee](https://www.cs.cornell.edu/home/llee/), [David Mimno](https://mimno.infosci.cornell.edu) WWW 2017 ([paper](https://arxiv.org/abs/1703.01725)) --- <img src="images/merged.png" alt="/r/aww"/ style="width:auto;"> *From top to bottom: examples of high scoring, okay scoring, and low scoring images from [/r/aww](https://www.reddit.com/r/aww/), [/r/FoodPorn](https://www.reddit.com/r/FoodPorn/), and [/r/cats](https://www.reddit.com/r/cats/).* --- In this work, we designed several time-controlled experiments to predict upvotes on image/text posts on Reddit. We focus on predicting relative popularity between submissions made in quick succession (e.g., 30 seconds). We find that we are able to successfully predict relative popularity using computer vision and NLP techniques, and that image/text content is generally more predictive of success than identity-based features. ## Dataset and Downloads Extracted image features, captions, social features, and pairing information for all 6 subreddits can be downloaded [here (3.3GB)](https://drive.google.com/open?id=0BxzmcRaXS-ByYTBwMXBxWTJyc3c). The readme of this dataset is available [here](http://www.cs.cornell.edu/~jhessel/cats/README.md). Image data is provided as pre-extracted features from [ResNet50](https://arxiv.org/abs/1512.03385). We have decided to not distribute raw jpegs because users might want to delete images from imgur in the future, or imgur itself might remove them for other reasons. However, if raw jpegs are needed for computer vision research, there is an included script that will re-download the raw files from imgur. We ask that anyone using this script *keep the built in rate limit* of 1 second per request. As of Feb. 2017, over 99.5% of images from each dataset are available publicly on imgur. Finally, if new extracted features (e.g., from a conv-net other than ResNet50) from the *exact* image set used in the paper are needed for comparison purposes, you may contact jhessel@cs.cornell.edu to request new extracted features. ### Raw posts and comments-in-context These files contain (non-deleted) posts from each community from reddit's inception until Feb. 2014. Also, each post is augmented with its associated comment tree. These files were used to create the social features used in the study. |Subreddit|Posts/Comments| |---|---| |[/r/pics](https://www.reddit.com/r/pics/)|[Posts/Comments (2.5GB)](https://drive.google.com/open?id=1WZS98OJdPWWDhyM-c0tfna-ZOUACqCFn)| |[/r/aww](https://www.reddit.com/r/aww/)|[Posts/Comments (392MB)](https://drive.google.com/open?id=1RM2FFmJfLayQ1YfkMvjQfMynxPUrVUnr)| |[/r/cats](https://www.reddit.com/r/cats/)|[Posts/Comments (53MB)](https://drive.google.com/open?id=1eQGppgyznU1-ks7qO1uBgAO0NpNMFOek)| |[/r/FoodPorn](https://www.reddit.com/r/FoodPorn/)|[Posts/Comments (27MB)](https://drive.google.com/open?id=1dfx25lFMSKEM6N2QyhUVWpZl-YvL7691)| |[/r/MakeupAddiction](https://www.reddit.com/r/MakeupAddiction/)|[Posts/Comments (146MB)](https://drive.google.com/open?id=11KnIdO_H8BepEr30fboZkrKC3VIv08m2)| |[/r/RedditLaqueristas](https://www.reddit.com/r/RedditLaqueristas/)|[Posts/Comments (45MB)](https://drive.google.com/open?id=1ZJxsWb7BvtUP9xC0vS9bfNtiBXT7K-UQ)| Update -- April 2018: data version 1.1! A small amount of missing data that does not effect the results of this study has been discovered. We did our best to re-fill the missing data (< 1% was missing), and the above downloads are the more-complete versions. The social features in the main dataset download are still the social features used in the study, for replicability sake. More details are available [here](http://www.cs.cornell.edu/~jhessel/reddit/gaps.html). ## Pretrained Image/Text Models Our pretrained models [are available here](https://github.com/jmhessel/catrank). Here are the model scores for my own pets, alongside some captions. These are scored according to the /r/aww model. <img src="images/bodhi-n.jpg" alt="bodhi" style="width:auto;"> *Who says bulldogs can't be cute???* - Score = 13.8/100 <img src="images/lizzy-n.jpg" alt="lizzy" style="width:auto;"> *My 20 year old little girl. Her sister passed away a while ago, but according to the vet, she's going as strong as ever! Reddit, meet Lizzy!* - Score = 87.5/100 <img src="images/taz-n.jpg" alt="taz" style="width:auto;"> *Please don't sit on me!* - Score = 27.4/100 ## Citation ``` @inproceedings{hessel2017cats, title={Cats and Captions vs. Creators and the Clock: Comparing Multimodal Content to Context in Predicting Relative Popularity}, author={Hessel, Jack and Lee, Lillian and Mimno, David}, booktitle={Proceedings of the 26th International Conference on World Wide Web}, year={2017}, organization={International World Wide Web Conferences Steering Committee} } ```
