A document classification method includes: obtaining a document; extracting document keywords and a document abstract from the document; determining, according to the document keywords and the document abstract, a first classification label of the document; receiving a second classification label of the document, the second classification label being determined according to the document keywords, the document abstract, and the first classification label; obtaining a classification efficiency value of the documents, the classification efficiency value indicating a confidence level of the second classification label; and determining the second classification label as a final classification label of the document if the classification efficiency value is greater than or equal to a first threshold. The document classification method described above may improve the speed of document classification by computer, thereby improving the efficiency of document classification.

Methods and compositions that affect yield and other agronomic characteristics in plants are disclosed. Methods of transgenic modulation and marker-assisted breeding methods improve grain size and grain yield in rice are also disclosed. Increased expression of BG1 results in increased grain size and yield.
