This multidisciplinary research investigates Twitter posts related to sexual assaults and rape myths by characterizing and detecting the types of malicious intent, which leads to the beliefs on discrediting women and rape myths. We analyze narrative contexts in which such malicious intents are expressed and discuss their implications for gender violence policy design. Pandey, R., Purohit, H., Stabile, B., & Grant, A. (2018).

We synthesize an alert-based ranking system that enforces these bounds to avoid overwhelming end-users for achieving the Human-AI collaboration.

Public expects a prompt response from online services, including emergency response organizations to requests for help posted on social media. However, the information overload experienced by these organizations, coupled with their limited human resources, challenges them to timely identifying and prioritizing such requests. We present a novel model to formally characterize social media requests and then, develop a Learning-to-Rank system using this model. Paper: Purohit, H., Castillo, C., Imran, M., and Pandey, R.

Humanitarian Informatics Approach for Cooperation between Citizens and Organizations - CSCW16 CADMICS talk /hemant_pt/cscw2016cadmicstalkpurohit cscw-cadmics16-talk-purohit-160303000611
Social networks have empowered citizens to voice their experiences, observations and share information, playing an important role for events related to humanitarian issues. Although a vast amount of data shared on social media may contain valuable information for the decision making, such as response planning in the crisis times, such as situating call for help, and resource availability, the conventional organizational information management face information overload challenge to ingest new information source of citizen-generated data. This paper positions a humanitarian informatics framework to address the information overload problem of organizational actors via a cooperative information system design between citizens and organizations, guided by process knowledge. The framework operationalizes computation into the design process by transforming computationally tractable parts of the design problems into data problems, which meet information needs of organizational actors. This approach can be leveraged for humanitarian problems beyond crisis coordination. ]]>

IEEE SocialCom 2015: Intent Classification of Social Media Text /slideshow/ieee-socialcom-2015-intent-classification-of-social-media-text/56448437 ieee-socialcom-2015-v2-151226025018
Social media platforms facilitate the emergence of citizen communities that discuss real-world events, and generate/share content with a variety of intent ranging from social good (e.g., volunteering to help) to commercial interest (e.g., criticizing product features). Hence, mining intent from social data can aid in filtering social media to support organizations, such as an emergency management unit for resource planning. However, effective intent mining is inherently challenging due to ambiguity in interpretation, and sparsity of relevant behaviors in social data. In this research, we address the problem of multiclass classification of intent with a use-case of social data generated during crisis events. Our novel method exploits a hybrid feature representation created by combining top-down processing using knowledge-guided patterns with bottom-up processing using a bag-of-tokens model. We employ pattern-set creation from a variety of knowledge sources including psycholinguistics to tackle the ambiguity challenge, social behavior about conversations to enrich context, and contrast patterns to tackle the sparsity challenge.]]>
