Abstract: For a given input query specifying a task to be performed on a website, the correct sequence of actions (or UI script) is machine learned without having any previous knowledge about the website or the query. To learn the correct UI script, a task agent is created that performs multiple task agent runs comprising different sequences of actions of UI elements on the website (e.g., buttons, text fields, menus, and the like). The states of the webpages are monitored after each action of a UI element is performed. Tasklets are created that include the performed sequences of actions for each task agent as well as their assigned scores, and the correct UI script is chosen from the tasklets based on the scores (e.g., tasklet with the highest score).
