Title: Automated Reasoning in the Age of the Internet

Abstract:

The internet hosts a vast store of information that we cannot and should not ignore. It’s not enough just to retrieve facts, to make full use of the internet we must also infer new information from old. This is an exciting new opportunity for automated reasoning, but it also presents new kinds of research challenge.

• There are a huge number of potential axioms from which to infer new theorems. Methods of choosing appropriate axioms are needed.

• Information is stored on the Internet in diverse forms, e.g., graph and relational databases, JSON (JavaScript Object Notation), CSV (Comma-Separated Values) files, and many others. Some contains errors and others are incomplete, lacking vital contextual details such as time and units of measurements.

• Data retrieved from the Internet must be automatically curated into a common format before we can apply inference to it. Such a representation must be flexible enough to adapt to different kinds of data and their attributes as well as support the novel kinds of inference we propose.

• We can employ forms of inference that are novel in automated reasoning, such as using regression to form new functions from sets of number pairs, and then extrapolation to predict new pairs.

• Information is of mixed quality and accuracy, so introduces uncertainty into the theorems inferred. Some inference methods, such as regression, also introduce uncertainty. Uncertainty estimates need to be inherited during inference and reported to users in an intelligible form. We will report on the FRANK system that explores this new research direction.
