Grading
The grading mainly depends on class distribution. The chart below is the grading criterion using a data classification.
Data Mining: Data Classification
The process finds the common properties among a set of objects in a database and classifies them into different classes, according to a classification model.
Information Retrieval: Data Clustering
The process of grouping physical or abstract objects into classes of similar objects is called clustering or unsupervised classification.
| The document clustering could be an alternative method of organizing retrieval results. |
