• determining, by the network device, the search behavior as the search behavior having the financial need in response to D(n)′ being greater than a threshold;
• grouping, by the network device, the plurality of users into a plurality of user groups according to the determined financial need related characteristics of the users, wherein each of the user groups has a corresponding financial need related characteristic;
• determining, by the network device, a financial instrument corresponding to each of the user groups by matching the financial need related characteristic of each of the user groups with instrument characteristics of a plurality of financial instruments;
• determining, by the network device, based on the determined financial instrument corresponding to each of the user groups, user attention information corresponding to each of the determined financial instrument, wherein the user attention information corresponding to each of the determined financial instrument includes a number of attentions of the users paid to the each determined financial instrument, the number of attentions being determined based on statistics of the financial instruments corresponding to the search behaviors, wherein the number of attentions of the users paid to the each determined financial instrument is acquired based on a number of search behaviors being acquired from the plurality of user devices;
• and
• publishing, by the network device over a network, on an information publishing platform, the determined financial instrument and the user attention information corresponding to each of the user groups, the determined financial instrument and the user attention information published on the information publishing platform being accessible by a plurality of network devices.

An apparatus for financial data mining, comprising:

• at least one processor;
• and
• a memory storing instructions and a set of rules for determining user attentions of financial instruments on the Internet, wherein the instructions when executed by the at least one processor, cause the at least one processor to perform operations, the operations comprising:
• acquiring search behavior information of a plurality of users from a plurality of user devices;
• determining, using the set of rules, based on the search behavior information of the plurality of users, financial instruments corresponding to search behaviors of the plurality of users, wherein the financial instruments include a financial product or financial information, and the search behaviors include search inputs to the plurality of user devices;
• and
• determining, based on the determined financial instrument corresponding to the search behaviors of the plurality of users, user attention information corresponding to each of the determined financial instruments, wherein the user attention information corresponding to each of the determined financial instruments includes a number of attentions of the users paid to the each determined financial instrument, and the number of attentions being determined based on statistics of the financial instruments corresponding to the search behaviors, wherein the number of attentions of the users paid to the each determined financial instrument is acquired based on a number of search behaviors being acquired from the plurality of user devices and determined as having a financial need for the each determined financial instrument;
• and
• publishing over a network, on an information publishing platform, the user attention information corresponding to each of the determined financial instruments, the user attention information published on the information publishing platform being accessible by a plurality of the plurality of user devices, wherein the search behaviors having the financial need for a given user is determined by:
• acquiring n search behaviors of the given user arranged in chronological order, n being a positive integer greater than 1;
• acquiring an initial financial need value of each of the n search behaviors, the initial financial need value being determined by a keyword in the each search behavior or a page accessed by the each search behavior;
• and
• determining whether the nth search behavior has a financial need based on a final financial need value D(n)′, wherein D(n)′=(1+f(D(n−1))×a)×D(n), wherein D(n−1) is the initial financial need value of the (n−1)th search behavior of the given user, D(n) is the initial financial need value of the nth search behavior of the given user, a is a weight value, f(D(n−1))=1 when D(n−1) is greater or equal to a preset threshold T, and f(D(n−1))=0 when D(n−1) is smaller than the preset threshold T.
