The representation of the knowledge has the objective of helping to resolution of problems and learning.
Knowledge is a group of organized and structured information ( group of data obtained on a certain problem beggining with abstractions of the reality) about a topic.
There are three types of knowledge: procedural, descriptive and metaknowledge.
Descriptive knowledge are objects, facts and relations between them.
Procedural knowledge is how to use the descriptive knowledge.
Descriptive knowledge is information about our knowledge.
Resolution of problems is to answer a series of questions beginning with some specific data.
The process of resolution of problems consists of 2 parts:
In the first one we do an abstraction of the problem (extraction of the relevant information) and we generate a model.
In the second one we do the application of the model or do inferences on up to obtaining the solution.
Learning is a process of storage of knowledge.
There are four requirements for learning: motivation, time, preparation and method.
There are two types of learning: first hand and second hand.
A speech of a given topic for somebody is an example of second hand learning.
Investigation on a topic is an example of first hand learning.
First Hand Learning consists in that you experience with tests of type tentative and error.
Second Hand Learning consists in that you believe things that other count to you.
The representation of the knowledge is done by means of the natural language or by means of the formal graphical language. (Diagrams, graphs, etc)
The natural language has the disadvantages of which it is ambiguous and linear whereas the formal graphical language give a clear vision, it does not have because to have a linear order and it takes advantage of the whole
potential of the mind.
