An information processing method and device thereof are provided according to the embodiments of the disclosure. The information processing method acquires a first file and a second file having a first association relation therebetween, acquires a first object and a second object in the first file, acquires a third object and a fourth object in the second file, and establishes a association relation between the second object and the fourth object in the case that the first object and the third object meet a first preset condition. In the disclosure, the second association relation between the second object in the first file and the fourth object in the second file is established by determining the first file and the second file having the first association relation and by means of the relation between the first object in the first file and the third object in the second file.
Please help me write a proper abstract based on the patent claims. CLAIM: 1. An information processing method, comprising: acquiring a first relation between a first file and a second file; acquiring information of a first object and information of a second object in the first file; acquiring information of a third object and information of a fourth object in the second file; judging whether the information of the first object and the information of the third object meet a first preset condition; and establishing a second relation between the second object and the fourth object, in the case that the information of the first object and the information of the third object meet the first preset condition. 2. The method according to claim 1, wherein acquiring a first relation between a first file and a second file comprises: acquiring a first attribute of the first file; acquiring a second attribute of the second file; judging whether the first attribute and the second attribute meet a second preset condition; and confirming the first relation between the first file and the second file, in the case that the first attribute and the second attribute meet the second preset condition. 3. The method according to claim 1, wherein establishing a second relation between the second object and the fourth object comprises: sending information of the fourth object to the second object; and/or sending information of the second object to the fourth object. 4. The method according to claim 3, further comprising: sending the second file to the second object; and/or sending the first file to the fourth object. 5. The method according to claim 1, wherein in the case that the first file belongs to a fifth object and the second file belongs to a sixth object, the method further comprises: establishing a third association relation between the fifth object and the sixth object, in the case that the information of the first object and the information of the third object meet the first preset condition. 6. An information processing device, comprising: a file acquisition module configured to acquire a first relation between a first file and a second file; a first acquisition module configured to acquire information of a first object and information of a second object in the first file; a second acquisition module configured to acquire information of a third object and information of a fourth object in the second file; a judgment module configured to judge whether the information of the first object and the information of the third object meet a first preset condition; and a first establishment module configured to establish a second association relation between the second object and the fourth object, in the case that the information of the first object and the information of the third object meet the first preset condition. 7. The device according to claim 6, wherein the file acquisition module comprises: a first acquisition unit configured to acquire a first attribute of the first file; a second acquisition unit configured to acquire a second attribute of the second file; a judgment unit configured to judge whether the first attribute and the second attribute meet a second preset condition; and a determination unit configured to determine that there is the first association relation between the first file and the second file, in the case that the first attribute and the second attribute meet the second preset condition. 8. The device according to claim 6, wherein the first establishment module comprises: a first sending unit configured to send information of the fourth object to the second object; and/or a second sending unit configured to send information of the second object to the fourth object. 9. The device according to claim 8, wherein the first establishment module further comprises: a third sending unit configured to send the second file to the second object; and/or a fourth sending unit configured to send the first file to the fourth object. 10. The method according to claim 1, wherein in the case that the first file belongs to a fifth object and the second file belongs to a sixth object, the device further comprises: a second establishment module configured to establish a third association relation between the fifth object and the sixth object, in the case that the information of the first object and the information of the third object meet the first preset condition.
