Many of us have used a digital assistant before (ranging from Google Assistant, Apple’s Siri, Amazon’s Alexa, Microsoft’s Cortana, and perhaps more). In this assignment, you will be creating a very simplistic version of a digital assistant such as these.
The digital assistant (DA) that you create will be MUCH simpler. The interface for using it will not be with your voice - rather, it will be with typed text on the python console. Also, it will only be able to recognize to main types of commands. You can either tell the DA something that you want it to remember, or you can ask the DA to recall something that you told it.
The first type of command (telling) will be a single sentence with the following form:
(entity) (category) (was / is / will be) (item)
There are four parts to this command.
entity is the name or title of an individual or group.
This would be words like my, your, his, hers, steve's, etc.
You can assume this all always be one word.category will be something like favorite sports team, first pet, or last meal.was, is, or will be (past, present, future).
Notice that this makes the implementation slightly tricky.
Two of the tenses are just one-word long, and one of them is two!item component is what foes along with the category.
It would be something like Phoenix Suns, bird, or chinese orange chicken.Below are a few examples of full commands:
my favorite meal is orange chickenyour longest work shift was 14 hourshis exercise program will be done in 1 monthYou program will need to extract the four components of each command that is entered, and save them in parallel lists.
In order to separate the components, you may want to use the split() function, as well as other advanced string features of python.
Any time the DA requests a command / sentence from the user, the line should begin with USER: .
You can also ask the DA for information that you have previously told it. These requests will take the following form:
what (tense) (entity) (category)?
These ask commands will always begin with the word what.
The tense, entity, and category should match up with what you previously saved / remembered.
Again, you’ll want to use the string split() function along with other string functionality to extract the components of the command.
You should use the strip() function to ignore the question-mark.
Any time the DA replies-to a command / sentence from the user, the line should begin with DA: followed by the message.
When DA accepts new information, it should reply with DA: OK!.
When the user asks the DA a question, the DA will reply with the expected information, or an error message.
See the examples below for what the replies should look like.
There is also a special-case for the DA replies. If the user refers to “my”, the DA will switch it to “your” in the reply. Also, “your” should be switched to “my”. This is shown in one of the examples below.
Let’s say that the user entered
USER: joe's favorite food is orange chicken
Your program should remember that the entity my told the program that their favorite food is (present tense) orange chicken.
Later, the user could say:
USER: what is joe's favorite food?
And the program should reply with:
DA: joe's favorite food is orange chicken.
If in the same program session, we were to then enter:
USER: joe's favorite food was pizza
DA: OK!
USER: joe's favorite food is salad
DA: OK!
USER: joe's favorite food will be pasta
DA: OK!
Then the following would be the program’s response:
USER: what is joe's favorite food?
DA: joe's favorite food is orange chicken
USER: what was joe's favorite food?
DA: joe's favorite food was pizza
USER: what will be joe's favorite food?
DA: joe's favorite food will be pasta
Notice in this example that: (A) the software remembers a different food for the same person, for each of the three tenses, and (B) the old “orange chicken” favorite was overwritten by the new “salad” preference for the present-tense (is) case.
