Table 3. Rules for generating multiple candidates from a sequence of tokens.

Parentheses rule. e.g., from “interleukin (IL)-4”, get “interleukin-4” and “IL-4”.

Suffix in conjunction rule. e.g., from “Protein kinase C alpha, beta, and gamma”, get “Protein kinase C alpha”, “Protein kinase C beta”, and “Protein kinase C gamma”. This rule will also cover cases like “ERK 1/2”, where “ERK 1” and “ERK 2” will be generated.

Suffix in range rule. e.g., from “ERK 1–8”, get “ERK 1”, “ERK 2”,. . ., “ERK 8”.
