In summary CoreNLG is just perfect:
-
if you use Python
-
if you do not need sophisticated linguistic features likes anaphora, verbs, words and ajectives agreements
-
if you are not afraid of maintaining texts templates as Python code
RosaeNLG can be better:
-
if you want more readable templates
-
if your NLG project requires linguistic resources
-
if you use Javascript or TypeScript
-
if you wish to make browser side rendering
xSpin
Spin generators are a category of tools that are able to generate a huge quantity of different texts for a same dataset. In general, you define a template with plenty of different paths, and the spinner will randomly go through the template and generate different texts. Spin generators are generally considered as basic pre-NLG software and are quite popular among web redactors. They are generally easier to use than NLG engines.
xSpin is a modern SaaS Spin generator with a visual design tool, and more advanced features than what is generally excepted from a Spin generator.
This comparison has been made in collaboration with Sylvain Deauré, the author of xSpin.

In summary xSpin is just perfect:
-
if you do not wish to code and need a visual interface to design your templates
-
if you do not need linguistic features likes anaphora, verbs, words and ajectives agreements
RosaeNLG is be better:
-
if you are ok to write some code
-
if you want to use standard developer tools like VSCode, Git versioning, CI, automated testing etc.
-
if your NLG project requires linguistic resources
