Pepper - Number recognition

Question

I'd like to use Pepper as a calculator... Now the first problem is the number recognition... Considering that "*" does not work, and that it is not possible to add all numbers as concept....It is a problem. I can write a concept composition to make recognize numbers in letters (not in numbers), e.g. "one hundred twenty one" instead of 121. Now I don't know how to convert the letters-number to digit-number in a simple way... (the only way I know is using a parser in a remote phyton function) Another problem is that I cannot make a "sum" in qiChat language. Is there a way to make a sum in qichat without using a %script? If I use a script I cannot assign the result to a qichat variable, the only way is using events... Thanks if you can suggest some simpler way to proceed. Debora

Answer 1

Starting from the 100s, the numbers are expressed in a systematic way, like in "three million two hundreds fifty two thousands six hundreds and ninety one" for "3,252,691".

As you can see, you don't need neither to capture * nor "all numbers", but rather a combination of just some possible chunks.

concept:(digits) ["one", "two", ...]
concept:(tens) ["ten", "twenty", ...]
concept:(number_tens) {~tens} {~digits}
concept:(number_hundreds) {~digit hundred{s}} ~number_tens
concept:(number) {~number_hundreds million{s}} {~number_hundreds thousand{s}} ~number_hundreds
u:(_~number}
    $number_out=$1

An ALMemory event named number_out should be raised with the value when a number is matched. You can subscribe to it, and process it with a script to convert the natural language into numbers, like propose here for example.
