1. A method, performed by a system for automatically generating text, the system comprising at least one hardware processor and at least one non-transitory computer-readable storage medium storing software encoding at least one system rule for determining which language from multiple language options is to be used to refer to a referent, the method comprising: using the at least one hardware processor to perform: accessing information specifying at least one referential expression for a first referent and at least one anaphoric expression for the first referent; accessing a template stored on the at least one non-transitory computer-readable storage medium, the template including human-language text and a first tag that serves as a placeholder for a first text portion including a first reference to the first referent; automatically identifying, using the software encoding the at least one system rule, text to use for the first text portion at least in part by determining whether to use as the text for the first text portion the at least one referential expression or the at least one anaphoric expression; automatically generating output text including the human-language text and the identified text for the first text portion; and presenting, via a device, the automatically generated output text to a user, wherein the at least one anaphoric expression comprises a plurality of anaphoric expressions for the first referent, wherein the plurality of anaphoric expressions for the first referent comprises at least one non-possessive reference, a first possessive reference for the first referent, and a second possessive reference for the first referent, each of the possessive references indicating possession of the first referent by a second referent, wherein the first possessive reference includes an anaphoric expression for the second referent, wherein the second possessive reference includes a referential expression for the second referent, and wherein when the automatically identifying determines to use the at least one anaphoric expression as the text for the first text portion, the automatically identifying comprises determining whether to use as the text for the first text portion the first possessive reference, the second possessive reference, or the at least one non-possessive reference.
