Abstract
Verbose and complicated legal terminology in online service terms and conditions (T&C) means that users typically don't read these documents before accepting the terms of such unilateral service contracts. With such services becoming part of mainstream digital life, highlighting Terms of Service (ToS) clauses that impact on the collection and use of user data and privacy are important concerns. Advances in text summarization can help to create informative and concise summaries of the terms, but existing approaches geared towards news and mi-croblogging corpora are not directly applicable to the ToS domain, which is hindered by a lack of T&C-relevant resources for training and evaluation. This paper presents a ToS model, developing a hybrid extractive-classifier-abstractive pipeline that highlights the privacy and data collection/use-related sections in a ToS document and paraphrases these into concise and informative sentences. Relying on significantly less training data (4313 training pairs) than previous representative works (287,226 pairs), our model outperforms extractive baselines by at least 50% in ROUGE-1 score and 54% in METEOR score. The paper also contributes to existing community efforts by curating a dataset of online service T&C, through a developed web scraping tool.
