## Commonsensical/kid-centric properties of cognition

Schank, Roger, Dynamic Memory Revisited (1999), Preface, Pg. viii. Schank says that “someone has to get a computer to know what a human knows about using a toaster or playing baseball”. Comments :  Children understand things at just the right level – not absolutely shallow, as in rote memory, and obviously not too deep. How doContinue reading “Commonsensical/kid-centric properties of cognition”

## Commonsense and Logic : a concise theory

Here is a long-standing phenomenon (problem, perhaps) in Commonsense Reasoning – commonsense v/s logic. While interpreting any data, there are a lot of possible ways to do it in. These possibilities are logical possibilities. But in everyday life, commonsense takes over, and makes us choose the “commonsensical” possibility. For example, if someone says to you (say,Continue reading “Commonsense and Logic : a concise theory”

## MODIFICATION OF MINSKY’S FRAMES : Mechanism for commonsense

Minsky says that – “When one encounters a new situation (or makes a substantial change in one’s view of the present problem) one selects from memory a structure called a Frame. This is a remembered framework to be adapted to fit reality by changing details as necessary. A frame is a data-structure for representing a stereotyped situation, like beingContinue reading “MODIFICATION OF MINSKY’S FRAMES : Mechanism for commonsense”

## What ‘commonsense’ is this?

Consider this sentence someone tells you –  The doctors did the surgery quickly. There are obviously 2 parts to the cognition of this sentence –  1) In cognition, we, first, obviously consider / understand what is given explicitly (that there were more than one doctor, they did a surgery, they did it quickly etc. ThisContinue reading “What ‘commonsense’ is this?”

## A Commonsense Law (Labeling)

Suppose V is the value of a property P, and V is associated with X, then the value of P of X is V.  *This is a commonsense law, not a logical necessity.  E.g. a player wearing a jersey (X) with ‘Beckham’ (V) written on it is Beckham (name = P). A bottle (X) withContinue reading “A Commonsense Law (Labeling)”

## The Definition of Definition

A word is defined in a context in which it is always present. A thief (defined as – one who steals) is defined in the context of the act of stealing, in which it is always present. (Similarly, the stolen thing CAN BE defined in the context of the act of stealing, in which it isContinue reading “The Definition of Definition”

## The Heart of Commonsense NLP – a technique to capture the “more”

What lies at the heart of Commonsense NLP is that the meaning of the sentence contains MORE than what is actually stated in the sentence in terms of words. What is this more? Can we capture it? Here is an idea. I) Lets look at this ‘MORE’, elementally. Make all the possible pairs of wordsContinue reading “The Heart of Commonsense NLP – a technique to capture the “more””

## Linguistic Commonsense

Let me introduce 2 kinds of verbs – ‘Free’ and ‘Attached’. Attached verbs are those verbs which have a variable in their definition. They are dependent upon an external variable entity for the completion of their Semantics. Free verbs are those which don’t have a variable in their definitions; they are “free” and self-sufficient. ForContinue reading “Linguistic Commonsense”

## Why just Naive “Physics”?

Consider 2 blocks kept near each other on a table. Apply force on one, the other will move too. How does a child understand this, which it experiences?  Consider this – If you show a blue bag to a child and suppose it goes near it and explores it, and finds chocolates inside. It seesContinue reading “Why just Naive “Physics”?”
