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:
