Grammar (needs to be in CNF)


Chart update interval (ms)

Click on Parse to start the CKY parsing animation. Once the animation is running, you can click on the chart to pause/resume it. When it's done, click again on the chart to restart it. If you want to try another grammar/sentence, press Escape (or just refresh the page). And, yes, it's your responsibility to put the grammar in Chomsky normal form.

Have fun ;-)
