Natural Language Processing (NLP) is the branch of computer science that focuses on algorithms to process and analyze natural language usage. NLP is inherently multidisciplinary, drawing on the fields of artificial intelligence, machine learning, linguistics, psychology, sociology, etc. to process unstructured data. In this age of big data and the ubiquity of social media, the need for sifting through large amounts of data to get relevant information is ever more present. Textual social media such as discussion fora, chat, Twitter, blogs, and Facebook commentaries make up a significant portion of social media. Yet, such media are mostly unstructured in nature, posing significant challenges for text analytics.
Despite the challenges, it is believed that social media language is a treasure trove for mining and understanding human interactions. There is a perceived correlation between language use on these media and human behavior. Due to the nature of the language used and the degree of diversity, processing such media constitutes the new challenging frontier for NLP systems.
As part of an emerging exciting subfield of NLP, computational sociopragmatic modeling of language use, Prof. Mona Diab and collaborators at Columbia University and University of Michigan were recently funded (by IARPA, the SCIL Program) to work on social media analysis using cutting edge NLP techniques. They investigated issues such as detecting the most influential participant in a discussion, identifying who is trying to grab power in a group, and, which participants in a group discussion are most likely to splinter off and form a group of their own. Though these social constructs of influence, pursuit of power, and subgroup formation are universal, interestingly (and perhaps unsurprisingly), research indicates that different languages manifest them exploiting rather distinct sociolinguistic devices reflecting significant cultural and linguistic variations. Identifying the most influential person(s) in a group or the person(s) seeking power in a group can shed a lot of information about the dynamics of a group and their interactions. Moreover, subgroup formations are quite nuanced: the same person can belong to multiple groups--for example people could agree on some topic such as liking the movie "The Matrix," but some within that group might disagree on rating the acting skills of Keanu Reeves. In discussion fora, people naturally form groups and subgroups aligning along points of consensus and contention.
Different sociological and anthropological factors come into play, but more importantly, the way participants express themselves in the text could help us identify how they think and how they will group. But a challenging question becomes, how much evidence is needed before we can decide whether people who share the same view points will actually form a subgroup. Is all evidence of alignment present explicitly in the text?
Prof. Diab and her students focused on the latter two questions for subgroup detection and emergence. They explored these questions in different social media fora, building automated systems to model the manifested language uses of participants in both English and Arabic. They successfully model some of the subtleties of language using advanced unsupervised learning models getting at both explicit and implicit agreement patterns among participants. They complemented their models with explicit modeling of the social media networks. Their developed systems yield state-of-the-art performance in detecting and predicting subgroup formation in social media discussion fora.
