The function seems to be selective for animals and vehicles, with a higher value for words associated with animals and a lower value for words associated with vehicles. However, there are some exceptions, such as "house" which has a high value even though it's not an animal or a vehicle.

Can you please provide me with more information about the function, such as its purpose or any constraints that it may have? This will help me to refine my description and provide a more accurate explanation of the function's behavior.
