1. An interactive object retrieval method, comprising: receiving a query and a time and space searching condition; selecting a plurality of data records of a first category complied with the time and space searching condition from an object database; comparing a similarity between the query and each of the data records of the first category to obtain a plurality of data records of a second category wherein a time information and a location information are corresponding to each of the data records of the second category; dividing the data records of the second category into a plurality of groups, wherein the data records of the second category in a same group correspond to a same location information, and a time difference between the time information corresponding to the data records of the second category in the same group does not exceed a predetermined value; respectively selecting the data records of the second category having a highest similarity with the query from each of the groups; taking all of the data records of the second category which are selected as a plurality of searching results; receiving at least one user input corresponding to at least one of the searching results from a user interface, wherein each of the at least one user input corresponds to a similarity decreasing operation or a similarity increasing operation; and determining a display manner of each of the searching results on the user interface according to the at least one user input and a similarity between the query and each of the searching results, comprising for each of the at least one user input, determining whether the user input corresponds to the similarity decreasing operation or the similarity increasing operation, so as to change a display size of one of the searching results on the user interface and to change the similarity between the query and the one of the searching results, wherein the one of the searching results is corresponding to the user input; and selecting the searching results that have the similarity with the query higher than a threshold value from all of the searching results to serve as a plurality of formal searching results.
