AGI use cases

(Some entries are just general description rather than concrete example;  It may take some additional time to think of concrete examples for them)


1. Pattern recognition

Programming related:

• recognize a program / a program missing a curly brace
• recognize a function declaration [maybe missing something]
• recognize a mathematical / logical expression
• recognize the definition of an abstract data type
• recognize that the execution of a program is slow (this is fuzzy)
• recognize that some code / data structure is complex (also fuzzy)
• recognize that a text / image file is big (also fuzzy)

English related:

• recognize some nouns, verbs, prepositions, etc
• recognize NPs, VPs, etc
• recognize sentences (or almost-sentences missing something)
• recognize misspelled words

2. Natural language understanding / interpretation

Syntactic parsing into logical form:

• translate nouns, verbs, prepositions, etc, into logical form
• translate NPs, VPs, into logical form
• translate sentences into logical form

Understanding semantics:

• understanding nouns:
      eg:  chair is an object, dog is an animal, love is an abstract thing
• understanding verbs:
      eg:  to kick is to hit with a leg;  to kiss is to make contact with lips;
            to love is to kiss, have sex, hold hands, talk, etc.
• understanding prepositions:
      eg:  John eats spaghetti with Peter -> Peter eats spaghetti
            John eats spaghetti with meatballs -> the spaghetti has meatballs &
                                                                        meatballs don't eat spaghetti
• understanding sentences

3. Learning from examples

Once we have basic English capability, we can use English to give examples:

• Roman numeral for '1' consists of one I
  Roman numeral for '2' consists of two I's
  Roman numeral for '3' consists of three I's
  -->  Roman numeral for n consists of n I's

4. Query answering

• Is 13 an integer?
• Is 13 an odd number?
• Is 3.14 a float?
• All variables must be given a type when they are declared?
• Every C# program must contain one Main method?
• Is ++(x + 1) a valid C# statement?

5. Finding explanations

• Why does some code result in error messages?
      eg:  why is ++(x + 1) invalid?
            what's wrong with  printf("This is a test);  ?
• Why doesn't a program give the desired result?
      eg:  why doesn't  printf("Hello world/n");  produce a new line?
• Why is one program slower than another similar program?

6. Performing simple tasks

• Print all odd numbers from 1 to 100.
• Replace "John" with "Mary" in this text file.
• Write a function that reverses an English sentence's word order.
