PPT-Exercises on Chomsky Normal Form and CYK parsing

1 Convert the following grammar to CNF S gt A S B A gt S S B x B gt S B y This is exercise is available in the grammar tutoring system httplaraserver3epflch9000. Also formal definitions of insertion anomaly and deletion anomaly are presented It is shown that a schema is in DKNF if and only if it has no insertion or deletion anomalies Unlike previously defined normal forms DKNF is not defined in terms of trad 1 Second Normal Form 32 Third Normal Form 33 Functional Dependencies 4 FOURTH AND FIFTH NORMAL FORMS 41 Fourth Normal Form 411 Independence 412 Multivalued Dependencies 42 Fifth Normal Form 5 UNAVOI ABL E RE DUNDA NCIES 6 INTERRECORD REDUNDA NCY 7 CO Ling 571.
