ByConceptual Graphs. Graph Structure Finite, connected, bipartite Arcs are not labeled Conceptual relation nodes are introduced between concepts The bipartite nature of the graph means concepts can only link to conceptual relations and vice versa

Relation. Relations. Recall the definition of the Cartesian (Cross) Product: The Cartesian Product of sets A and B, A x B, is the set A x B = {< x,y > : xA and yB }. A relation is just any subset of the CP!! R AxB Ex: A = students; B = courses.

Relation. What will you learn?. Definition of relation Expressing relation. Definition of Relation. Dina likes to eat strawberry and watermelon. Ani likes to eat pineapple. Cika likes to eat watermelon. If set A = { Dina, Ani, Cika} and set B = {strawberry, pineapple, watermelon}

Relation. Combining Relations. Because relations from A to B are subsets of A x B, two relations from A to B can be combined in any way two sets can be combined. Let A = {1, 2, 3} and B = {1, 2, 3, 4}. The relations R 1 ={(1, 1), (2, 2), (3, 3)} and

Relation . Def: A relation is any set of ordered pairs. Ex) { ( 2, 3), ( 4, -3), ( 5, 9), ( 3, 2) } Def: The Domain (Input) of a relation is the set of all x values. D = { 2, 4, 5, 3 } Def: The Range (Output) of a relation is the set of all y values. R = { 3, - 3, 9, 2 } .

Discrete Math for CS. Binary Relation Exercise:. If R = { (a,b): a < b}. Show R on the diagram below.. . . A. B. . . . . . . . . 8. 6. 4. 2. 1. 3. 5. 7. . . . . . . . . . . . . . . . . Discrete Math for CS. Binary Relations as Sets of Ordered Pairs:. Because we mention one set before another in a Cartesian Product, A x B, the element, (a,b), in any relation, R, over A and B must have its first element from A and its second element from B.So we say that the elements of R form ordered pairs..
