SOCIALITE-LLAMA: An Instruction-Tuned Model for Social Scientific Tasks

Social science NLP tasks, such as emotion or humor detection, are required to capture the semantics along with the implicit pragmatics from text, often with limited amounts of training data. Instruction tuning has been shown to improve the many capabilities of large language models (LLMs) such as commonsense reasoning, reading comprehension, and computer programming. However, little is known about the effectiveness of instruction tuning on the social domain where implicit pragmatic cues are often needed to be captured. We explore the use of instruction tuning for social science NLP tasks and introduce SOCIALITE-LLAMA— an open-source, instruction-tuned LLAMA2. On a suite of 20 social science tasks, SOCIALITE-LLAMA improves upon the performance of LLAMA2 as well as matches or improves upon the performance of a state-ofthe-art, multi-task finetuned model on a majority of them. Further, SOCIALITE-LLAMA also leads to improvement on 5 out of 6 related social tasks as compared to LLAMA2, suggesting instruction tuning can lead to generalized social understanding.
