at least one processor operatively connected to the communication module; and a memory storing a plurality of contents, and operatively connected to the at least one processor, wherein the memory stores instructions which, when executed, cause the at least one processor to: obtain a plurality of keywords associated with the plurality of contents, hierarchically classify the plurality of contents based on the plurality of obtained keywords, so as to produce one or more groups, identify a representative keyword corresponding to each of the one or more groups, combine the identified representative keyword and a content included in each of the one or more groups, so as to produce a navigation model, and store the produced navigation model. ### Claim 7 (depends on 6) The electronic device of claim 6, wherein the instructions further cause the at least one processor to: identify information associated with the plurality of contents from one or more databases accessible by the memory or the electronic device; and extract the plurality of keywords based on the information associated with the plurality of contents. ### Claim 8 (depends on 6) The electronic device of claim 6, wherein the instructions further cause the at least one processor to obtain the plurality of keywords from an external server using the communication module. ### Claim 9 (depends on 6) The electronic device of claim 6, wherein the instructions further cause the at least one processor to classify the plurality of contents using a hierarchical clustering scheme. ### Claim 10 (depends on 6) The electronic device of claim 6, wherein the instructions further cause the at least one processor to determine the representative keyword based on at least one of an average similarity between contents included in each of the one or more groups, a keyword type, or a search history. ### Claim 11 (depends on 6) The electronic device of claim 6, wherein the instructions further cause the at least one processor to: identify context information associated with a user of the electronic device, set a weight value for at least one keyword related to the identified context information, determine, based on the set weight value, a representative keyword corresponding to each of the one or more groups, and store a first model produced based on the determined representative keyword as a navigation model corresponding to the context information. ### Claim 12 (depends on 6) The electronic device of claim 6, wherein the instructions further cause the at least one processor to: in case that a new content is identified as being stored in the memory, obtain at least one keyword associated with the new content, and update the navigation model using an incremental clustering scheme. ### Claim 13 A method of operating an electronic device, the method comprising: displaying, on a display, one or more keywords for searching for a content; in response to identifying that a first keyword is selected among the one or more keywords, arranging and displaying, according to a designated criterion, one or more first categories among subordinate categories associated with the first keyword and one or more first contents associated with the first keyword; in case that a selection input to one of the one or more first categories is identified, arranging and displaying, according to the designated criterion, one or more second categories among the subordinate categories associated with a selected category and one or more second contents associated with the selected category; and in case that a selection input to one of the one or more first contents is identified, providing the selected content. ### Claim 14 (depends on 13) The method of claim 13, wherein the displaying of the one or more first categories and the one or more first contents comprises: in case that selection of the first keyword is input, identifying setting information associated with a number of items capable of being displayed;
