Faceted Curriculum Project/About Lexemes

A lexeme is a keyword used in the summary of a block. Sometimes, a lexeme will include multiple words; for example, the expression "scientific notation" is an individual lexeme, since its meaning is "indivisible" (does not follow directly from the meaning of the words "scientific" and "notation").

FCP Lexeme Creation
A new FCP Lexeme should be created for each essential word in a block summary.

FCP Lexeme Description
For each FCP Lexeme, a page is provided which includes definitions of the Lexeme, as well as links to blocks which use the Lexeme. There should be multiple definitions for each Lexeme, corresponding to varying audiences:
 * A mathematician's definition, sufficient for supporting the usage of the word in mathematical facet.
 * A teacher's definition, sufficient for explaining a concept to teachers.
 * A student's definition, meant to explain a concept to students.

The mathematician's definition should be created first. The other definitions should be no less precise than the mathematician's definition.

Inter-lexical Dependence
Some definitions of lexemes require knowledge of other lexemes -- cross-referencing can be done easily through links. When there is such a dependence of definitions, a semantic link should be used. For example, the definition of rational numbers relies on the definition of integers. Hence, there would be a link such as: Lexically Depends On::integer when integers are mentioned in the definition of rational numbers.

In this way, one can easily ensure that there are no circular definitions within the lexicon.
