What is information theory?

The quantitative value of information! The more surprising the information is to the reader, the higher its value!

The father of information technology stated, "The value of information is the magnitude of surprise." The more familiar the recipient is with the content of the information, the less valuable that information becomes. Conversely, the less the recipient knows about the content, the more valuable the information is. In other words, the value of information changes relatively based on how well the recipient understands the subject matter. This is defined as the amount of information. Based on probability theory, the way to quantify the value of information has been established. The greater the surprise from information that the reader does not know, the higher the value of that information. 【Levels of Communication Problems】 ■Level A: Technical Issues How accurately can symbols be transmitted in communication? ■Level B: Semantic Issues How accurately can the transmitted symbols convey the intended meaning? ■Level C: Effectiveness Issues How effectively does the received intention influence the desired action? *For more details, please refer to the PDF document or feel free to contact us.

What is information quality?

Quality assessment of qualitative information! Introducing differences in quality based on expression, causality, and scope!

Information quality is a qualitative evaluation indicator of information. The value of information is considered to be the magnitude of surprise, according to information theory. So, if the content is surprising, is it acceptable to write dubious or false information? No, that is not correct. By checking the content against the indicators of information quality, it becomes possible to enhance the value of the content. The related links explain the differences between data quality and information quality. 【10 Indicators of Information Quality (Partial)】 ■ Authority/Reliability/Verifiability ■ Scope of Coverage ■ Composition and Organization ■ Objectivity ■ Integrity *For more details, please refer to the related links page or feel free to contact us.

Content Quality Improvement Service Procedure

Valuable information varies from person to person! It starts with 'knowing yourself and knowing your opponent'!

The value of information is influenced by the difference between what the other party knows and what we possess, and this difference is calculated based on probability distributions. This consulting begins by clarifying what we know and what the other party does not know, starting from "knowing oneself and knowing the other." Consulting mainly consists of discussions and hearings. If objective data is needed, market research will also be conducted. 【Service Procedure】 ■1. Hearing ■2. Site Analysis ■3. Determination of Pages for Information Quality Improvement ■4. Page Analysis ■5. Application of Improvement Proposals ■6. Confirmation of Improvement Effects ■7. Formulation of Next Improvement Measures *For more details, please refer to the PDF document or feel free to contact us.
