Papers

Mapping to Declarative Knowledge for Word Problem Solving (2018)
Instead of learning each arithmetic operation directly from text, this solver first picks a mathematical concept for every operation in the expression tree and then a specific declarative rule under that concept, which fixes the operation.
Unit Dependency Graph and its Application to Arithmetic Word Problem Solving (2017) measured
The paper adds explicit reasoning about units of measure to an arithmetic word-problem solver. It introduces the Unit Dependency Graph (UDG): one node per quantity plus one for the question, where a node can be marked as a rate ("40 miles per hour", or implicitly "each student has 3 books") with a numerator and a…
Solving General Arithmetic Word Problems (2015) measured
The paper solves multi-step arithmetic word problems without predefined equation templates by representing the answer as an expression tree in which each number from the text is used at most once.
