Based on prior knowledge, the occupation of an individual can be a strong predictor of their income level. Some occupations, such as 'Exec-managerial' or 'Prof-specialty', are more likely to earn higher than 50000 dollars per year, while others like 'Other-service' or 'Priv-house-serv' are less likely to earn that income.

Here is the analysis of the relationship between the 'occupation' feature and the task of earning more than 50000 dollars per year:

- Values likely to earn more than 50000 dollars per year: ['Exec-managerial', 'Prof-specialty']
- Values less likely to earn more than 50000 dollars per year: ['Other-service', 'Priv-house-serv']

Based on this analysis, here is the dictionary:

```json
{
	"no": ["Other-service", "Priv-house-serv"],
	"yes": ["Exec-managerial", "Prof-specialty"]
}
```

Note that we have not included values that are hard to predict or do not have a sufficient number of samples to draw conclusions.
