WebEarley Parser • It uses a dynamic programming table, just like CKY • Example entry in column 1 – [0: 1] VP -> VP. PP – Created when processing word 1 – Corresponds to words 0 to 1 (these words correspond to the VP part of the RHS of the rule) – The dot separates the completed (known) part from the incomplete (and possibly unattainable) part
