To analyze the relationship between the feature "contact" and the task of whether the client subscribes to a term deposit, we can look at the distribution of contact communication types for each target class.

Here is the analysis and the resulting dictionary:
```json
{
	"no": ["unknown", "cellular", "telephone"], 
	"yes": ["unknown", "cellular", "telephone"]
}
```

Based on the given feature description, the contact communication type can take three categories: "unknown", "cellular", and "telephone". From the analysis, we observe that each target class (yes and no) includes all three contact communication types. Therefore, in the resulting dictionary, the list of possible values for both target classes includes all the available contact communication types.
