Some embodiments include a computer-implement method of producing a flexible sentence syntax to facilitate one or more computer applications to generate and publish sentence expressions. For example, the method can include providing a developer interface to define a flexible sentence syntax that controls one or more sentences publishable by an application service. A developer of the application service can customize the flexible sentence syntax including selecting at least one of selectable tokens that is associated with a specific sentence element to incorporate in the flexible sentence syntax. Based on the selected token, a computing device can generate and publish a target sentence according to the flexible sentence syntax on the application service's behalf.
