2018-11-08 "Google opinion poll" [長年日記]

"Public opinion" is hard to investigate.

Mass media, government, etc can do large scale questionnaire to obtain these information.

However, such activities are limited to corporations with financial resources.

Weekend writers can not compete at all.

Because a weekend writer cannot compete at all, I should do simulation and use various mathematical calculations and inference tools, as palliation.

Recently, I am using "Google" search engine as a simple method of investigation of public opinion.

Although the purpose is not the same as the questionnaires, if you enter a specific term, you can get the number of hits directly. It is suitable for investigating rough public opinion.

For example, if you compare the number of hits with the term "nursing care" and "enjoyable nursing care", you can see that the concept of "enjoyable care" is less than 0.01% of the content "nursing care".

In fact, we can judge that there is no concept of "enjoyable care" in the world.

By using the service of "Google Trend", we can know when a specified words appeared and disappeared.

For example, we can know the lifecycle of the words of "M2M" "Long tail" and "Big Data" with "Google Trend"

Google is the super lowest method to investigate "Public opinion"

It is

"Google opinion poll"
