I used to write20/80 rule re-interpretationHere, we will mention the following:
The 20/80 law is also called the law, that is, the Balec law. Balec's law was invented by the Italian economist Balec at the end of the 19th century and the beginning of the 20th century. He believes that, in any group of things, the most important thing is only a small part, about 20%, and the remaining 80%, although the majority, is secondary, so it is also known as the law.
In the design of search engines, it can be said that 80% of the results on the first page of most search engines are the same, but only 20% of the results are different. But this is exactly the 20% make different.
The 20% difference is also the gap between different search engines. It is crucial for a search engine to improve the 20% difference.
On the other hand, you can improve a search engine by 20%. For example, if you want to improve the performance by 80%, it may take 20% effort to improve the effect of the remaining 80%.
In a simple example, a search engine is still relatively elementary, and the accuracy of word segmentation and search may be around 80%. To further improve the accuracy, you may need to adjust 40 or 50 parameters, we have adjusted many factors and considered many algorithms. After a great deal of effort, we found that we only improved a little and adjusted it again. After three times, we may have found 90% after a long time, this 10% is a big breakthrough, but it will take more effort than the amount from 0% to 80%.
The gap between search engine parameters may be only a few percentage points, but these few percentage points are the real difference, and the winner and the loser are created.
From the aspect of search, the 20 80 rule has another significance. 80% of searches are concentrated on a small number of keywords, that is, 20% of search words account for 20% of the total search traffic. The word frequency can be obtained through the daily statistics of the search engine. In some special cases, these distributions can be used to correct the search engine.
