Abstract: Methods and systems for providing trending search terms are provided. The method includes determining first search ranking values of one or more search terms based on a number of inputs of the one or more search terms input from a plurality of first user terminals, receiving weights of a plurality of categories from a second user terminal, determining correlations of the plurality of categories with the one or more search terms, determining second search ranking values of the one or more search terms by applying the weights of the plurality of categories to the correlations of the plurality of categories with the one or more search terms, and determining final search ranking values of each of the one or more search terms based on the first search ranking values and the second search ranking values.

Abstract: A personal data processing method includes providing personal data of a user to a blockchain network by means of a personal identification key in the blockchain network that is registered for the user in different services that identify the same user with different identifiers. The personal data of the user in the different services can be tracked and utilized with the personal identification key.

Abstract: Exemplary embodiments provide a computer-implemented method of enabling a recommendation of a software to a user from a software marketplace based on activities of the user's friend of an internet-based social network who is related to the first user within the confines of the social network, said user maintaining an internet-based social network account, the method comprising: receiving, from the first user, a selection of an interface associated with the software marketplace, generating, by a computer-implemented recommendation system, a list of recommended software based on the internet-based social network into which the first user is logged into, sending the list of the of recommended software to the first user, wherein the computer-implemented recommendation system retrieves the information of the user's friend and assigns a weight to a post not displayed based on an attribute thereof.

Abstract: A method and system for analyzing competition results is disclosed, the method comprising providing a probability model to analyze competition results including both information about options used for a competition process, and rank information of competition participants; and determining a first parameter about a pure ability of each competition participant, and a second parameter about advantages and disadvantages of the option used for the competition process by analyzing the competition results using the probability model, wherein the first and second parameters are determined by calculating a prior distribution of the second random variable, calculating a likelihood function of the second random variable, and estimating the first and second parameter through the use of the prior distribution of the second random variable and the likelihood function.

Abstract: A method and system for providing an advertisement using a minimum incremental unit are provided. The advertisement providing method includes adjusting a minimum incremental unit based on an initial bid price, an input bid price, and a maximum bid price bid price during an auction. The minimum incremental unit includes a minimum value of increment to be included in a current input bid price in addition to a previously input bid price.

Abstract: A charging method and system for determining an advertising cost according to a unit time are provided. The charging method includes checking a performance index numerically indicating performance of an advertisement; checking a priority index of a next-priority advertisement to the advertisement; and determining an actual charge per unit time of the advertisement based on the performance index, the priority index, and a predetermined weight.

Abstract: A method, system, and computer-readable recording medium for holding an auction and imposing a charge in relation to a search advertisement are provided. The method includes receiving bid information related to the search advertisement from an advertiser calculating device, the bid information including a search keyword, a posted time of the search advertisement, and a bid price for the search advertisement, determining a posting position and/or a posting order of the search advertisement with respect to a predetermined time slot of the posted time of the search advertisement, based on the bid price corresponding to the time slot, and posting the search advertisement according to the determined posting position and/or the posting order for the predetermined time slot.

Abstract: Disclosed is a method and system for managing quality of an advertising document. The method of managing document quality may include verifying a number of actual clicks corresponding to a number of clicks that may occur during a predetermined period with respect to at least one document that may exist on the Web, verifying a number of expected clicks corresponding to a number of clicks that may be expected to occur during the predetermined period with respect to the at least one document, and determining a quality management index by which quality of the at least one document may be numerically expressed based on the number of the expected clicks and the number of the actual clicks.

Abstract: A method and system for offering an advertisement by adjusting a bid price per unit time according to advertising traffic are provided. The advertisement offering method includes determining a bid price per unit time based on an average bid price input by an advertiser and advertising traffic, and determining a charge regarding the advertisement of the advertiser based on the bid price per unit time.
