As described in c:recognition, no semantic interpretation is
attached to mathematical content at the recognition step. AsTeR
can be enhanced to recognize specialized notation and produce
context-sensitive renderings (*e.g.,* speak
[tex2html_wrap5734] as ``x squared''). Some context-specific
processing is needed to produce such renderings, and this
section outlines the kind of information that is available: the
weight of an object and special patterns.

Measure `weight` quantifies the complexity of math
expressions. The weight function is defined as follows:

- The weight of a leaf node with attributes is [tex2html_wrap5736] plus the sum of the weights of its attributes. Attributes are themselves math objects, and their weight is computed recursively.
- The weight function on non-leaf nodes is defined recursively:
