Abstract Wikipedia will generate natural language text from an abstract representation. This is not a novel idea, and it has been tried a number of times before.
This page aims to collect different existing approaches. It tries to summarize the core ideas of the different approaches, their advantages and disadvantages, and points to existing implementations. This page (by and for the community) will help to choose which approach to focus on first.

In their 2018 Survey, Gatt and Krahmer begin by describing natural language generation as the "task of generating text or speech from non-linguistic input." They identify six sub-problems (after Reiter & Dale 1997, 2000) [2.NLG Tasks, pp. 70-82]:
- Content determination (content determination (Q5165077))
- Text structuring (document structuring (Q5287648))
- Sentence aggregation (aggregation (Q4692263))
- Lexicalisation (lexical choice (Q6537688))
- Referring expression generation (referring expression generation (Q7307185))
- Linguistic realisation (realization (Q7301282))
Please note that the six topics listed above have articles only in the English Wikipedia (24 July 2020).
These six sub-problems can be seen as a segmentation of the “pipeline”, beginning with “early” tasks, aligned to the purpose of the linguistic output. The “late” tasks are more aligned to the final linguistic form. A summary form might be “What (1), ordered (2) and segmented (3) how, with which words (4&5), in which forms (6)”. Lexicalisation (4) is not clearly distinguished from “referring expression generation” (REG) (5) in this summary form. The key idea during REG is avoiding repetition and ambiguity, or managing the tension between those conflicting aims. This corresponds to the Gricean maxim (Grice, 1975) that “speakers should make sure that their contributions are sufficiently informative for the purposes of the exchange, but not more so” (or, as Roger Sessions said (1950) after Albert Einstein (1933): “everything should be as simple as it can be but not simpler!”).
Referring expression generation
- “In linguistics, realization is the process by which some kind of surface representation is derived from its underlying representation; that is, the way in which some abstract object of linguistic analysis comes to be produced in actual language. Phonemes are often said to be realized by speech sounds. The different sounds that can realize a particular phoneme are called its allophones.”
- “Realization is also a subtask of natural language generation, which involves creating an actual text in a human language (English, French, etc.) from a syntactic representation.”

In a later survey, Gârbacea and Mei suggested “Neural language generation” as an emerging sub-field of NLG. Eleven of the papers cited in their survey have titles with “neural language” in them, the earliest from 2016 (Édouard Grave, Armand Joulin, and Nicolas Usunier). The earliest citation in which “neural language generation” appears is from 2017 (Jessica Ficler and Yoav Goldberg).
In mid 2020, “neural language generation” is not mature enough to be used to generate natural language renditions of language-neutral content.
