1. A computer-implemented interactive searching method, comprising: obtaining, at one or more computing device, a query from a webpage on a user device; and generating, at the one or more computing device, intention clarification information of the query according to a history search log associated with the query and a predetermined semantic knowledge base, the intention clarification information configured to be displayed in the webpage on the user device and including at one least candidate query related to the query; and generating, at the one or more computing device, guiding information, the guiding information configured to be displayed in the webpage on the user device and including at least one question related to the query from the webpage on the user device; wherein the semantic knowledge base comprises a plurality of words having a semantic hypernym-hyponym relationship and/or a semantic sibling relationship; wherein the step of generating an intention clarification information comprises: segmenting, at the one or more computing device, the query into at least one word; obtaining, at the one or more computing device, a hyponym set and/or sibling set of the at least one word according to the history search log associated with the at least one word and the semantic knowledge base; generating, at the one or more computing device, interactive candidates configured to clarify a query intention according to the hyponym set and/or sibling set; and combining, at the one or more computing device, the interactive candidates to form the at one least candidate query; and wherein the step of generating guiding information comprises: obtaining, at the one or more computing device, first information according to a configuration template; obtaining, at the one or more computing device, second information according to a word set configured to generate the interactive candidate; obtaining, at the one or more computing device, third information according to the query, in which the word set comprises the hyponym set and the sibling set; and combining, at the one or more computing device, the first information, the second information and the third information to form the guiding information; wherein obtaining second information according to a word set configured to generate the interactive candidate comprises: obtaining, at the one or more computing device, one or more of the following: a hypernym of the hyponym set from the at least one word and a hypernym of the sibling set; matching, at the one or more computing device, an interrogative set with the hypernym according to a predetermined language model; obtaining, at the one or more computing device, an expression with a highest probability of matching; and treating, at the one or more computing device, the expression with the highest probability of matching as the second information.
