1. A method for generating a journal, wherein the method is performed by a hardware processor in a computer, the method comprising: obtaining a source data set and a journal description data set corresponding to the source data set; calculating an alignment probability between each source data sequence in the source data set and each journal description data sequence in the journal description data set to obtain an alignment probability set, wherein the source data sequence comprises at least one piece of source data, and wherein the journal description data sequence comprises at least one piece of journal description data; calculating a probability that each journal description data sequence occurs in the journal description data set to obtain an occurrence probability set; determining, according to the alignment probability set and the occurrence probability set and from each journal description data sequence, a target journal description data sequence corresponding to a source data sequence to be translated, wherein the source data sequence to be translated is any one of a plurality of source data sequences; and translating the target journal description data sequence into a journal description text.
