Claim:
A method for providing object information on the Internet, comprising: configuring a plurality of front-end categories for a plurality of network objects and a plurality of screening conditions determined based at least in part on the plurality of front-end categories for screening the plurality of network objects, each of the plurality of screening conditions uniquely corresponding to a respective one of the plurality of the front-end categories, wherein a screening condition of the plurality of screening conditions that corresponds to a front-end category of the plurality of front-end categories describes a property of one or more network objects that match the front-end category; receiving input object information pertaining to a network object comprising a commodity to be stored at a server; creating a first back-end category associated with data stored at the server including by: configuring the first back-end category according to a classification scheme of the network object; and correlating the network object with a selection of the first back-end category that is input via a terminal; storing the input object information pertaining to the network object in the first back-end category associated with data stored at the server; determining that the network object matches the front-end category by determining that the input object information pertaining to the network object stored in the first back-end category at the server meets the screening condition corresponding to the front-end category; in response to the determination that the network object matches the front-end category, storing a category identifying information associated with the front-end category in a commodity index associated with the network object at the server; displaying at least a portion of the plurality of front-end categories at a user interface; receiving a selection to a displayed front-end category; in response to the selection to the displayed front-end category, identifying a correlating object stored in a second back-end category associated with data stored at the server based at least in part on a category identifying information associated with the displayed front-end category; outputting object information pertaining to the identified correlating object at the user interface; receiving an instruction to modify the screening condition corresponding to the front-end category; and modifying the screening condition based at least in part on the instruction.
