Referring to FIG. 3, the service providing apparatus 200 receives identification code information of goods from the terminal 100 (S10). Then, the goods information searching unit 210 of the service providing apparatus 200 searches the identification code DB 271 for goods information corresponding to the identification code information (S20).

The product information searching unit 210 uses the product name, which is one of the product information, as an instruction word, and transmits the instruction word to the price comparison information searching unit 200 and the association analysis unit (S30). The product name, which is one of the goods information, corresponds to the main command.

The main command is inputted to the command extracting unit 230. [ The instruction extracting unit 230 morphs the main instruction and then separates the main instruction into words and generates a plurality of instructions (S40). A plurality of commands separated from the main command corresponds to a subordinate command. For example, if the product name is 'AAA Notebook XXX PS30', the subcommand can be AAA, notebook, XXX or PS30.

The subcommand is also input to the price comparison information searching unit 220. [ The price comparison information searching unit 220 searches for price comparison information based on the sub-command. Thus, in step S53, the instruction-based price comparison information search is performed using the main instruction and sub-instructions.

The main command and sub command are input to the search ranking analyzer 240. The search ranking analyzer 240 receives a plurality of commands, analyzes the search ranking of the commodities corresponding to the respective commands, and transmits product information having a search ranking to the price comparison information searching unit 220. The plurality of commands are broadly meant to include both main and subordinate commands, and narrowly refer to subordinate commands. The price comparison information searching unit 220 searches for price comparison information based on the goods information inputted from the search ranking analyzing unit 240. Thus, in step S54, the search ranking-based price comparison information search is performed.

For example, when the subordinate command is AAA company and a notebook, the search ranking analyzer 240 obtains the first to fifth rank search products among the AAA products, and the first to fifth rank search products And transmits it to the comparison information searching unit 220. Then, the price comparison information searching unit 220 generates price comparison information for products corresponding to the search order for each sub-command.

The main command and sub command are input to the search history analyzer 250. The search history analyzer 250 receives a plurality of commands, analyzes the user's search history of the commodities corresponding to the commands, and transmits the searched product information to the price comparison information searching unit 220. [ The price comparison information searching unit 220 searches for price comparison information based on the product information inputted from the search history analyzing unit 250. [ Thus, the search history-based price comparison information search is performed in step S55.

For example, when the sub command is the AAA company and the notebook, the search history analyzer 240 searches the price comparison information search unit 220 for the previous searched product if there is a history that the user has previously searched for the AAA company or notebook product . Then, the price comparison information search unit 220 generates price comparison information for products corresponding to the search history for each sub-command.

The main command and sub command are input to the situation analyzer 260. [ The context analyzer 260 receives a plurality of commands, analyzes the context of the commodities corresponding to the commands, and transmits the related commodity information to the price comparison information retrieval unit 220. [ The price comparison information searching unit 220 searches for price comparison information based on the goods information inputted from the situation analyzing unit 250. [ Thus, the context-based price comparison information search is performed in step S56.

The situation analyzer 260 checks the time information at the time of requesting the product search as a sub-command word and the context, and transmits the product information associated with the sub-command word corresponding to the time information to the price comparison information search unit 220 ). For example, when the sub-command is a notebook and the time information is night, price comparison information may be generated for a speaker product connected to the notebook so that the user can listen to music quietly at night.

In this manner, the service providing apparatus 200 may perform the command-based search ranking based search history based context-based price comparison information search and then integrate the generated price comparison information in step S57. The service providing apparatus 200 provides the integrated price comparison information to the terminal 100.
