Based on my prior knowledge, I can analyze how the feature "contact" relates to the target variable "Does this client subscribe to a term deposit?" (Yes or No). Here are my findings:

By analyzing the relationship between the "contact" feature and the target variable, we can determine the possible values of the "contact" feature for each class of the target variable.

For the target class "No" (client does not subscribe to a term deposit), the possible values of the "contact" feature are:
- 'unknown'
- 'cellular'
- 'telephone'

For the target class "Yes" (client does subscribe to a term deposit), the possible values of the "contact" feature are:
- 'unknown'
- 'cellular'
- 'telephone'

Therefore, the dictionary will be as follows:

```json
{
	"no": ["unknown", "cellular", "telephone"],
	"yes": ["unknown", "cellular", "telephone"]
}
```
