Abstract
A method to identify information about a mathematical formula may include receiving a mathematical formula included in a first electronic document. The method may also include generating a formatted formula from the mathematical formula. The method may also include finding a returned formula that is similar to or the same as the formatted formula in a plurality of mathematical formulae. The method may also include identifying from at least one other electronic document content that describes the returned formula and includes a derivation of the returned formula.
Claims22
A method to identify information about a mathematical formula, the method comprising:
- receiving a mathematical formula included in a first electronic document;
- generating a formatted formula from the mathematical formula;
- finding a returned formula that is similar to or the same as the formatted formula in a plurality of mathematical formulae;
- and
- identifying from at least one other electronic document a formula derivation that includes a derivation of the returned formula, wherein identifying from the at least one other electronic document the formula derivation that includes the derivation of the returned formula comprises:
- locating a position of the returned formula in the at least one other electronic document;
- determining whether the at least one other electronic document is paginated;
- in response to the at least one other electronic document being paginated, setting a current boundary around the returned formula based on a current page of the at least one other electronic document;
- locating other formulae within the current boundary in the at least one other electronic document;
- determining, for each of the other formulae, a distance between the returned formula and a corresponding one of the other formulae;
- and
- calculating a score based on the distance and similarity between each of the other formulae and the returned formula.
