1. Person

Names of people (e.g. Virginia Wade). Don’t mark people that don’t have their own name. Include punctuation in the middle of names. Fictional people can be included, as long as they’re referred to by name (e.g. “Harry Potter”).

Examples:

2. Location

Names that are locations (e.g. France). Don’t mark locations that don’t have their own name. Include punctuation in the middle of names. Fictional locations can be included, as long as they’re referred to by name (e.g. “Hogwarts”).

Examples:

If you can visit it, and the word’s used as a location, then mark it like one.

3. Corporation

Names of corporations (e.g. Google). Don’t mark locations that don’t have their own name. Include punctuation in the middle of names.

Examples:

If you can buy shares in it, or it has employees, and the word’s used as a corporation, then mark it like one.

4. Product

Name of products (e.g. iPhone**). Don’t mark products that don’t have their own name. Include punctuation in the middle of names.

There may be no products mentioned by name in the sentence at all - that’s OK. Fictional products can be included, as long as they’re referred to by name (e.g. “Everlasting Gobstopper”). It’s got to be something you can touch, and it’s got to be the official name.

Examples:

If you can touch it, you can buy it, and it’s the technical or manufacturer name for it, then mark it.

5. Creative work

Names of creative works (e.g. Bohemian Rhapsody). Include punctuation in the middle of names. The work should be created by a human, and referred to by its specific name.

Examples:

If it’s the specific name of a creative work, for example a movie, song or book, then mark it.

6. Group

Names of groups (e.g. Nirvana, San Diego Padres). Don’t mark groups that don’t have a specific, unique name, or companies.

There may be no groups mentioned by name in the sentence at all - that’s OK. Fictional groups can be included, as long as they’re referred to by name.

Examples:

If it’s a special name that refers to a unique, specific group, then mark it.
