Making the Planet Greener with Technology

Greenery of the planet is probably lesser harmful gases in the atmosphere, more trees on the planet, controlled natural disasters including temperatures of the planet.

And technology probably means silicon chips, which are harmful for the atmosphere with all its ingredients of sesame and such stuff.

How is it possible to combine these two things?

It is possible to make a planet greener with the technology, if it is aided with mighty brains of smart people working for the welfare of the planet.

Green technological products can range from using bio-fuel in the cars to LED bulbs in homes. Producing electricity from renewable sources, switching off TV and computer monitors when they are in standby mode, can also contribute a lot to the greenery of the planet. Fitting solar panels on houses for producing electricity for domestic purposes, using cycles instead of cars whenever possible, all come under technological efforts for helping the planet against green house gases

Knowledge Representation Overview

Knowledge state is a subject in cognitive science as well as in artificial info and knowledge modeling. In cognitive science it is concerned with how grouping store and process information. In Artificial intelligence (AI) and knowledge modeling (KM) it is a way to store knowledge so that programs can process it and use it for example to support computer-aided design or to emulate human intelligence. AI researchers have borrowed state theories from cognitive science. There are state techniques much as frames, rules and semantic networks which have originated from theories of human aggregation processing. Since knowledge is used to achieve intelligent behavior, the fundamental goal of knowledge state is to represent knowledge in a manner as to facilitate inference from knowledge. Here are some of the issues that arise in knowledge state from an AI are:

  • How do people represent knowledge?
  • What is the nature of knowledge and how do we represent it?
  • Should a representation scheme deal with a particular domain or should it be general purpose?
  • How expressive is a representation scheme or formal language?
  • Should the scheme be declarative or procedural?

There has been very little top-down discussion of the knowledge representation (KR) issues and research in this area is a well aged quilt work. There are well recognized problems such as “spreading activation”, “subsumption” and “classification.” For example a tomato could be classified both as a fruit and a vegetable. In the field of artificial intelligence, problem solving can be cut down by an appropriate choice of knowledge representation. Representing knowledge in some ways makes certain problems easier to solve. For example, it is easier to divide numbers represented in Hindu-Arabic numerals than numbers represented as Roman numerals.
