Method, apparatus, and computer program product for written mathematical expression analysis

摘要

Various methods for written mathematical expression analysis are provided. One method may include receiving written input where the written input is representative of a mathematical expression. The method may also include analyzing the written input to identify at least one operator and at least one operand and constructing an expression tree based at least in part on predefined symbol relationships, the at least one operator, and the at least one operand. Similar apparatuses and computer program products are also provided.

1. A method comprising:
receiving written input, the written input being representative of a mathematical expression; analyzing the written input to identify at least one operator and at least one operand; constructing, via a processor, an expression tree based at least in part on predefined symbol relationships, the at least one operator, and the at least one operand; wherein constructing the expression tree includes inserting, based at least in part on the predefined symbol relationships, a placeholder within the expression tree for a missing operator, a missing operand, or a missing parenthesis and wherein the placeholder separately identifies whether the placeholder is for a missing operator, a missing operand, or a missing parenthesis; analyzing the expression tree to identify an error based at least in part on one or more predefined rules; and providing for display of a feedback message corresponding to the error, wherein the feedback message may include a suggestion for correcting the error.
