system is measured; recall is the ratio of the number of related documents retrieved and the number of related documents in the document library, which is measured by the recall of the retrieval system. In general, precision is the number of items retrieved (such as documents, Web pages, etc.) that are accurate, and recall is how much of the exact entries have been retrieved. The correct rate, recall rate and F value are the important evaluation indexes of the target in the mixed environ

The accuracy rate, recall rate, and F value are important evaluation indicators of the target in a mixed environment. In this paper, these three indicators are favored. Let's take a look at the definition of these indicators first: Accuracy Rate = Total number of correctly recognized individuals/total number of identified individuals Recall rate = Total number of correctly recognized individuals/total number of individuals in the test set F value = accuracy * recall rate * 2/(accuracy rate +

In the database, a null value is used to indicate that the actual value is unknown or meaningless. In a table, if a column in a row has no value, it is called NULL ). A null value can be returned for any data type column as long as the non-NULL or primary key integrity restriction is NOT used. In practical applications, ignoring the existence of null values may cause unnecessary troubles. For example, in the following employee table (EMP), the employee name (ENAME) is KING's Row, because KING i

of precision and recall, and b>1 indicates more emphasis on p E =1-(b^2 + 1)/(1/p + b^2/r) =1-(b^2+1) *p*r/b^2*p +r) Example: There are 1400 carp, 300 shrimp and 300 turtles in a pond. Now for the purpose of catching carp. Sprinkle a big net, caught 700 carp, 200 shrimp, 100 turtle. So, these indicators are as follows: Accuracy = 700/(700 + 200 + 100) = 70% Recall rate = 700/1400 = 50% F value = 70% *

correct message bar/sample extracted The value is between 0 and 1, the closer the value is to 1, the higher the precision or recall. 3. F = Correct rate * Recall rate * 2/(correct rate + recall rate) (f value is the correct rate and recall rate of the harmonic mean) Take this example: there are 1400 carp, 300 shrimp and 300 turtles in a pond. It is now for the purpose of catching carp. 700 Carp, 200 shrimp and 100 turtles were caught in a large net.

(such as documents, Web pages, etc.) is accurate, recall is the number of all accurate entries have been retrieved. The correct rate, recall rate and F value are the important evaluation indexes to select the target in the mixed environment. Take a look at the definition of these indicators first: Correct rate = number of correct message strips/extracted information strips Recall rate = Number of information in the correct Information Bar/sample extracted The value is between 0 and 1, the close
