1. Information Processing Definition of Information processing All operations exerted to the information itself for its better utilization Information processing is necessary because most of the information in its original form may not be good for use. Thus information processing is the basis of later operations Two categories of information processing Shallow Level of Information Processing 2)Deeper level of Information Processing
1. Information Processing Definition of Information processing: All operations exerted to the information itself for its better utilization. Information processing is necessary because most of the information in its original form may not be good for use. Thus information processing is the basis of later operations. Two categories of information processing: 1) Shallow Level of Information Processing 2) Deeper Level of Information Processing
Shallow level of Information Processing 1. Processing for better operation: information transformation expression 2. Processing for better transferring communication exchange 3. Processing for better maintaining: record storage 4. Processing for better sharing copying reproduction 5. Processing for better retrieval classification, ordering, indexing
Shallow Level of Information Processing 1. Processing for better operation: information transformation & expression 2. Processing for better transferring: communication & exchange 3. Processing for better maintaining: record & storage 4. Processing for better sharing: copying & reproduction 5. Processing for better retrieval: classification, ordering, indexing
Deeper level of Information Processing 1. Processing for higher efficiency: compression based on syntax and semantics 2. Processing for improving noise immunit error correction based on syntax semantics 3. Processing for purifying recognition filtering 4. Processing for security improving cryptography based on syntax semantics 5. Processing for better utility: prediction, search, inference, computation

Information Cognition The purpose of information cognition is to produce knowledge from information refining. Information: The state its varying manner. Knowledge: The states their varying laws Cognition nformation Knowledge
