Some potential mistakes

[msesboue]

• Section 1.2.2, page 11, paragraphe 4: "commerece" --> "commerce"
• Sections 3.3.9 (page 73), 3.3.10, and 3.4.6 (page 90): I believe there is a copy and past issue. The expected KG should be (order-2)-paymentMethod->(Visa). (Not "Paypal")
• Ora Lassila's Biography, first line: "Technolgist" --> "TechnolOgist"

Sec 2.2.7 Scenario 3: "(Address)-state->[string]" is redundant/confusing, as State is now a concept and stateName is an attribute.

Sec 2.3.1 Example 2.4 resulting kg schema and kg: there are two "entity_id" attributes with the same representation. I know the book is not using verbose IRIs or anything, but I would expect these distinct concept attributes, which happen to both have a range of [int], to have different notational representations.

Sec 2.3.2 Example 2.5: "(customer-1)" should be "(customer-100)", "(customer-2)" should be "(customer-101)", as per the entity_id values in the table given.
