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.

basic information

**Overview** ■ Information theory is a mathematical theory of information and communication. In 1949, the father of information technology published a paper titled "A Mathematical Theory of Communication." In 1950, he published a book titled "The Mathematical Theory of Communication." Note that in the 1949 paper, the article in the title is "A," while in the 1950 book, it is "The." ■ Initially, when it was presented as a paper, it was introduced as one way of thinking, but by the following year, it had been established as a theory. *For more details, please refer to the PDF document or feel free to contact us.*

We have established and operate measurement and monitoring centers in five cities across the country (Sapporo, Niigata, Tokyo, Osaka, and Fukuoka). The measurement and monitoring systems in operation there are also used by major IT companies such as Google and Microsoft, as well as e-commerce sites and mobile companies like Verizon. We monitor the communication status of your web systems from various locations 24/7, analyze the data, optimize it, and support high-speed and stable web operations. We can detect communication failures and server issues, which have been occurring frequently lately, through measurements from across the country and immediately raise alerts. Additionally, we provide a web performance tuning service that ensures the display speed of websites, web applications, and mobile applications is completed within one second nationwide, achieving a 98% yield. Based on statistical quality control, we conduct data collection and analysis, and guarantee the achievement of displaying within one second through genuine performance tuning that addresses issues from the source code. Please feel free to contact us if you have any requests.
