Based on my prior knowledge, the occupation of an individual can be a significant indicator of whether they earn more than $50,000 per year or not. Certain occupations, such as Exec-managerial or Prof-specialty, are more likely to have higher salaries compared to occupations like Other-service or Handlers-cleaners.

To create the dictionary, I will analyze the relationship between the occupation feature and the task of earning more than $50,000 per year:

```json
{
	"no": ["Machine-op-inspct", "Farming-fishing", "Other-service", "Handlers-cleaners"],  
	"yes": ["Protective-serv", "Prof-specialty", "Exec-managerial", "Tech-support", "Sales", "Craft-repair", "Priv-house-serv", "Transport-moving"]  
}
```

Note that the "?" category is hard to predict, so it is not included in the dictionary.
