Recognition and retrieval of mathematical expressions
Citation:
Recognition and retrieval of mathematical expressions. Written by: Richard Zanibbi , Dorothea Blostein.
Summary:
This paper surveys recognition and retrieval of mathematical expressions, organized around four key problems in math retrieval (query construction, normalization, indexing and relevance feedback), and four key problems in math recognition (detecting expressions, detecting and classifying symbols, analyzing symbol layout, and constructing a representation of meaning).
The problems arising in Math Notation recognition are:
1) Expression Detection
2) Symbol Extraction or Symbol Recognition
3) Layout Analysis
4) Mathematical content Interpretation
It creates two kinds of trees for equation recognition: Symbol layout tree and Operator tree. The following problems arise in retrieval of Math notation:
1) Query languages and query formulation
2) Normalization
3) Indexing and matching
4) Relevance feedback
In solving the ambiguity of mathematical expressions, we first need to understand the meaning of what do each of the symbols represent.
Discussion:
This paper has given many future work ideas. Also, while doing our project, we felt on the same lines as the author (that solving the ambiguity in Math expressions, we need to understand meaning of each symbol). The use of various tools like MathML and Latex is very intuitive.
