Automatic Curation of Content Tables for Educational Videos
ACM - SIGIR'19
Traditional forms of education are increasingly being replaced by online forms of learning. With many degrees being awarded without the requirement of co-location, it becomes necessary to build tools to enhance online learning interfaces. Online educational videos are often long and do not have enough metadata. Viewers trying to learn about a particular topic have to go through the entire video to find suitable content. We present a novel architecture to curate content tables for educational…
Traditional forms of education are increasingly being replaced by online forms of learning. With many degrees being awarded without the requirement of co-location, it becomes necessary to build tools to enhance online learning interfaces. Online educational videos are often long and do not have enough metadata. Viewers trying to learn about a particular topic have to go through the entire video to find suitable content. We present a novel architecture to curate content tables for educational videos. We harvest text and acoustic properties of the videos to form a hierarchical content table (similar to a table of contents available in a textbook). We allow users to browse the video smartly by skipping to a particular portion rather than going through the entire video. We consider other text-based approaches as our baselines. We find that our approach beats the macro F1-score and micro F1-score of baseline by 39.45% and 35.76% respectively. We present our demo as an independent web page where the user can paste the URL of the video to obtain a generated hierarchical table of contents and navigate to the required content.

Battlefield: Quantifying and Modeling Intra-community Conflicts in Online Discussion
ACM-CIKM 2019
In this work, we present a novel quantification of conflict in the online discussion. Unlike previous studies on conflict dynamics, which model conflict as a binary phenomenon, our measure is continuous-valued, which we validate with manually annotated ratings. We address a two-way prediction task. Firstly, we predict the probable degree of conflict a news article will face from its audience. We employ multiple machine learning frameworks for this task using various features extracted from news…
In this work, we present a novel quantification of conflict in the online discussion. Unlike previous studies on conflict dynamics, which model conflict as a binary phenomenon, our measure is continuous-valued, which we validate with manually annotated ratings. We address a two-way prediction task. Firstly, we predict the probable degree of conflict a news article will face from its audience. We employ multiple machine learning frameworks for this task using various features extracted from news articles. Secondly, given a pair of users and their interaction history, we predict if their future engagement will result in a conflict. We fuse textual and network-based features together using a support vector machine which achieves an AUC of 0.89. Moreover, we implement a graph convolutional model which exploits engagement histories of users to predict whether a pair of users who never met each other before will have a conflicting interaction, with an AUC of 0.69.
