The APP is specifically introduced in two kinds of situation below how according to the incidence relation of pre-set image feature and text information
To determine the pre-set image feature:
Situation one:
When the APP is after determining to meet the text information of text constraint condition, the APP can use trained
Text classifier classifies the text information for meeting text constraint condition, if meeting text constraint condition than described
Text information be " Cheng Long ", then the APP, which can use trained text classifier, is classified as name class for " Cheng Long "
Not；If the text information for meeting text constraint condition is " Cibotium barometz (L.) J. Sm ", then the APP can use trained text
" Cibotium barometz (L.) J. Sm " is classified as animal category by classifier；If the text information for meeting text constraint condition is " automobile ", then
The APP can use trained text classifier and " automobile " be classified as goods categories.
Wherein, the trained text classifier can be and text information is referred in some given classification
Classifier.
The incidence relation of the pre-set image feature and text information, can be, but not limited to pre-set image feature and name class
The incidence relation of other incidence relation, pre-set image feature and animal category or the pass of pre-set image feature and goods categories
Connection relationship etc..
If the APP classifies the text information for meeting text constraint condition determined, determine that this is full
It, being associated with according to pre-set image feature and name classification after the text information of sufficient text constraint condition belongs to name classification
System, determines that the pre-set image is characterized in face characteristic.
Situation two:
