This context could be derived by analyzing a small text, such as "Today I would like to get either an orange fruit, a green fruit, or a purple vegetable."

In a simple model, natural language processing tells us that an attribute/adjective X applies to an object/noun Y if the phrase X Y appears somewhere in the text.

There are two formal concepts contained in this context:

C1 = {(fruit,orange), (fruit,green)}

C2 = {(vegetable,purple)}

Each of these is a maximal complete bipartite subgraph.
