However, there is more anaphora in texts than coreference. I present a computational treatment of other-anaphora, i.e., referential noun phrases (NPs) with non-pronominal heads modified by “other ” or “another”: [...]themoveisdesigned to more accurately reflect the value of products and to put steel on more equal footing with other commodities.
