Word will not be polymerized in two keyword sets.For example, if one group of keyword phrase includes 3 keywords, 3 keys
Word inherently polymerize into a keyword phrase.It should be further noted that if polymerizeing to the same keyword set
There are the same or similar keywords in different keyword phrases, then can carry out at duplicate removal to the same or similar keyword such as this
Reason.
2) computer equipment object according to described in each keyword, by the pass for the object that directly description matches
Keyword is polymerized to a keyword set, to obtain at least one keyword set.
For example, in step s 4, computer equipment obtains keyword: Key1, Key2, Key3, Key4, Key5, Key6.?
In step S5, the computer equipment directly object according to described in each keyword, by the keyword Key1 of description " Asian Games ",
Key2 is polymerized to a keyword set, and Key3, Key4, Key5, Key6 for describing " World Championships " are polymerized to a key
Set of words.
It should be noted that the above-mentioned examples are merely illustrative of the technical solutions of the present invention, rather than to limit of the invention
System, it should be appreciated by those skilled in the art that any by the keyword for the object that will describe to match in the multiple keyword
It is polymerized to a keyword set, to obtain the implementation of at least one keyword set, should be included in model of the invention
In enclosing.
It should be noted that coming after keyword set is determined to keyword included in the keyword set
From the user that is paid close attention to of object information, be also determined as user corresponding to the keyword set.
It should be noted that step S4 and step S5 can be performed a plurality of times for different object informations, to obtain new pass
Keyword set.If also, step S5 be based on its implementation 1) Lai Zhihang, can will before step S5 acquired keyword
Set is used as keyword phrase, and using keyword phrase as minimum polymerized unit, the keyword phrase that will be obtained in step S4
And the keyword set as keyword phrase obtained before step S5 is polymerize together, to obtain updated pass
Keyword set；If step S5 is based on its implementation 2) Lai Zhihang, it can be to set of keywords acquired before step S5
In keyword and step S4 in the keyword that obtains polymerize, to obtain updated keyword set.
It should be noted that the long period can be spaced between step S4 and step S5, with step S1, step S2, step S3.
For example, when obtaining, the time is newer after passing through one or many execution step S4 and S5 and obtaining at least one keyword set
