9. 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: a template that includes human-language text and a first tag that serves as a placeholder for a first text portion including a first reference to a first referent; software encoding at least one system rule for determining which language from multiple language options is to be used to refer to a referent; and processor-executable instructions that, when executed by the at least one hardware processor, cause the at least one hardware processor to perform: accessing information specifying at least one referential expression for the first referent and at least one anaphoric expression for the first referent; accessing the template that includes the human-language text and the first tag that serves as the placeholder for the first text portion including the 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.
10. The system of claim 9 , wherein the template further includes a second tag that serves as a placeholder for a second text portion including another reference to the first referent, wherein the second tag precedes the first tag in the template, and wherein the determining comprises: determining to use the at least one anaphoric expression as the text for the first text portion when the system has determined to use the at least one referential expression to replace the second tag in the template, and when the second tag is within a threshold distance of the first tag in the template.
