Abstract

Internet users face challenges in evaluating the validity of online information. Such evaluation is not adequately supported by current tools; we outline some of the shortcomings of these tools, including centralization, lack of automation, and lack of user-centrism. We propose a set of design principles to mitigate these shortcomings and introduce ALPACA, A Lightweight Platform for Analyzing Claim Acceptability, which adheres to these design principles. ALPACA provides a graphical means of organizing the user's trust with regard to information claims and sources, as well as tools for examining the trust assumptions of others.
