Step S202 obtains active user and acts on the current operation behavior set of terminal, in current operation behavior set
Each operation behavior act on corresponding content substance.
Specifically, content substance refers to that the content object shown in terminal, content object can be with text, voice, image, sounds
The different expression forms such as frequency and video are shown alone or in combination, for example, content substance can be one with text and figure
Piece combines the medical treatment & health to be formed and pushes away text or medical supplies advertisement etc..Operation behavior refers to the received operation object of acting on
Movement, such as may include click, transmission, sharing, collection, purchase, deletion, top set, one of move down and move up or more
Kind.Operation behavior acts on content substance and refers to the operation behavior for the content substance, and content substance is operation behavior
Operation object.It pushes away the link of text for example, clicking one or has sent the consultation information etc. of an online interrogation.
The time for obtaining current operation behavior set, which can according to need, to be configured, such as be can be set and ought received
Active user also can be set to current operation behavior set is obtained in real time after the once-through operation behavior of content substance every default
Such as every two hour in period obtains once-through operation behavior set, or obtains once-through operation behavior every default operation behavior
Set, it is default before obtaining current time when can also be that the current operation behavior of user meets preset recommendation trigger condition
Operation behavior in period obtains current operation behavior.
It is appreciated that each operation behavior may all act on different content substances in current operation behavior set,
It is also likely to be partly or entirely to act on identical content substance.Therefore, content substance may include one or more.In this reality
It applies in example, after server obtains current operation behavior set, the operation object of each operation behavior is obtained, as corresponding content
Entity.For example, it is assumed that in the first operation behavior include click A push away text operation behavior, send B interrogation information operation behavior with
And the operation behavior of collection C commodity, then first content entity sets include that A pushes away text, B interrogation information and C commodity.
Step S204 selects at least one recommendation plan compatible with content substance from preset Generalization bounds set
Slightly, the corresponding object to be recommended of content substance is obtained according to the Generalization bounds of selection.
Specifically, Generalization bounds refer to calculating reference data according to default rule to obtain object to be recommended
Method.In the present embodiment, a variety of Generalization bounds have been stored in advance on server, including but not limited to, have been based on correlation rule
Generalization bounds, Generalization bounds based on article collaborative filtering, the Generalization bounds based on user collaborative filtering, pushing away based on content
Recommend strategy, Generalization bounds, the total sales volume based on commodity or the Generalization bounds of total browsing time based on user's portrait etc..
The reference data type that each Generalization bounds has it to determine in Generalization bounds set, for example, based on use
The Generalization bounds of family portrait, reference data type can be merchandise news, be also possible to text information, cooperateed with based on article
The Generalization bounds of filter, reference data can be merchandise news, but cannot be text informations.The compatible recommendation plan of content substance
Slightly refer to that content substance reference data type corresponding with Generalization bounds is adapted, a content substance can correspond to one
Or multiple Generalization bounds, for example, the Generalization bounds of adaptation can be based on association when content substance is medical treatment & health commodity
The Generalization bounds of rule, the Generalization bounds based on user collaborative filtering, are based on content at the Generalization bounds based on article collaborative filtering
Generalization bounds etc., when content substance is interrogation text or medical treatment & health text, the content substance of adaptation, which can be, to be based on
The Generalization bounds of user's portrait.
In the present embodiment, after server gets content substance, judge data type belonging to the content substance, according to
Data type selects compatible at least one Generalization bounds as target Generalization bounds, is then pushed away according to the Generalization bounds
Calculating is recommended, the corresponding object to be recommended of content substance is obtained.
Step S206 updates the corresponding current recommendation list of Generalization bounds according to the corresponding object to be recommended of content substance.
Specifically, current recommendation list refer to obtain current operation behavior set before each Generalization bounds it is corresponding to
The list that recommended arranges in a certain order.In one embodiment, current recommendation list can be right by its
The Generalization bounds answered carry out off-line calculation according to historical data and obtain, and historical data can be the historical operation behavior collection of user
It closes, is also possible to historical viewings amount, history sales volume of commodity etc..The corresponding current recommendation list of Generalization bounds is updated to refer to
Object to be recommended in recommendation list is updated, specifically, can be the corresponding object to be recommended of content substance is straight
It connects and is added into recommendation list, reconfigure to obtain recommendation list with object to be recommended original in recommendation list;It is also possible to pair
Object to be recommended in the corresponding object to be recommended of content substance and recommendation list is ranked up according to its corresponding recommendation, choosing
The forward preset quantity that sorts object composition recommendation list to be recommended is taken, wherein recommendation must be that Generalization bounds carry out recommendation meter
The numerical value obtained when calculation can be scoring, similarity, support or the confidence level of object to be recommended according to the difference of Generalization bounds
Deng.
Step S208, the corresponding updated current recommendation list of each Generalization bounds from preset Generalization bounds set
It is middle to choose object to be recommended, target recommendation list is obtained according to the object to be recommended of selection.
In the present embodiment, server can be regular from the corresponding current recommendation of each Generalization bounds according to what is be previously set
Object to be recommended is chosen in list.Specifically, can be chosen from each current list to be recommended equal amount wait push away
Object is recommended, for example, needing 20 objects to be recommended in target recommendation list, there are four recommend altogether in preset Generalization bounds set
Strategy, each corresponding recommendation list of strategy to be recommended, then chosen respectively from each recommendation list respectively 5 it is to be recommended
Object;Or weight is arranged to each Generalization bounds in advance, it is to be recommended right to choose from each list to be recommended according to weight ratio
As for example, the corresponding weight ratio of four Generalization bounds is 1:2:1:1, then respectively from four recommendation lists in the example above
The object number to be recommended chosen is 5,10,5,5.
Further, it after server gets object to be recommended, treats recommended and is arranged according to preset ranking factor
Sequence obtains target recommendation list, wherein ranking factor includes but is not limited to order numbers, pageview, cost rate, amount of collection, click
Amount etc..
In one embodiment, it after server obtains target recommendation list, further obtains each in target recommendation list
Then the inventory data of commodity is filtered target recommendation list according to stockpile number, filters out library in target recommendation list
Deposit the commodity to be recommended that quantity is 0.
Further, target recommendation list is sent to terminal and carries out recommendation by server shows.
In above-mentioned recommended method, server obtains the current operation behavior set for acting on terminal, current operation behavior collection
Each operation behavior in conjunction acts on corresponding content substance, selection and content substance phase from preset Generalization bounds set
At least one Generalization bounds of adaptation carry out recommending that content substance pair is calculated according to the Generalization bounds of selection to content substance
The object to be recommended answered updates the corresponding current recommendation list of Generalization bounds according to the corresponding object to be recommended of content substance, from
Object to be recommended is chosen in the corresponding current recommendation list of each Generalization bounds, target is obtained according to the object to be recommended of selection and is pushed away
List is recommended, is recommended simultaneously due to using a variety of Generalization bounds, object to be recommended and user demand can be significantly improved
Matching degree, to meet the needs of users to greatest extent.
In one embodiment, as shown in figure 3, to obtain content substance according to the Generalization bounds of selection corresponding to be recommended
Object, comprising:
Step S302, segments content substance, obtains word segmentation result.
In the present embodiment, content substance be can be including at least one of interrogation data and medical treatment & health text.Specifically,
Interrogation data refer to that user carries out data caused by online interrogation in terminal, can be text information, voice messaging or view

In the present embodiment, server first segments content substance, obtains word segmentation result, and word segmentation result refers to
The sequence of terms of the word composition one by one obtained after participle.Such as, the participle obtained after " open cerebellar hemorrhage " participle
It as a result can be with are as follows: opening/cerebellum/bleeding.Content substance is segmented, specifically, can be incited somebody to action first according to punctuation mark
It is divided into the complete sentence of a rule to content substance, then word segmentation processing is carried out to the sentence of each cutting, such as using character string
Matched segmenting method carries out word segmentation processing to the sentence of each cutting, such as Forward Maximum Method method, the sentence of a cutting
In character string segment from left to right;Alternatively, reversed maximum matching method, the character string in the sentence of a cutting from the right side to
A left side segments;Alternatively, shortest path segments method, it is minimum that the word number cut out is required inside the character string in the sentence of a cutting
's;It is forward and reverse while carrying out participle matching alternatively, two-way maximum matching method.Also using meaning of a word participle method to each cutting
Sentence carries out word segmentation processing, and meaning of a word participle method is a kind of segmenting method of machine talk judgement, is believed using syntactic information and semanteme
Breath segments to handle Ambiguity.Word segmentation processing also is carried out to the sentence of each cutting using statistical morphology, from current
In the historical search record of the historical search record of interrogation user or public users, according to the statistics of phrase, can count some two
The frequency that a adjacent word occurs is more, then can segment using the two adjacent words as phrase.
Step S304, extracts keyword from word segmentation result, obtains keyword set.
Specifically, keyword refers to the corresponding word of the key message in content substance.In one embodiment, it extracts
The step of keyword, is as follows:
1) part-of-speech tagging processing is carried out to each word in word segmentation result, and filters out stop words, only retain specified part of speech
Word obtain candidate keywords such as noun, verb, adjective.
2) candidate keywords figure G=(V, E) is constructed, wherein V is node collection, is made of the candidate keywords that (1) generates, so
The side between two o'clock is appointed using cooccurrence relation (co-occurrence) construction afterwards, there are sides only when they are right between two nodes
The vocabulary answered co-occurrence in the window that length is K, K indicate window size, i.e., most K words of co-occurrence.
3) referring to following formula, the weight of each node of iterative diffusion, until convergence.
Wherein, wherein V indicates that word node, WS indicate word node weights in formula.W indicates side right weight, the word formed according to side
The similarity of node obtains, and d is damped coefficient, and value range is 0 to 1, and it is any other to represent a certain specified point direction from figure
The probability of point, general value are that 0.85, In indicates the point set for being directed toward the word node, and Out indicates the word section that the word node is directed toward
The point set of point.
5) to word node weight carry out Bit-reversed, obtain corresponding word node according to the size of weight, from big to small according to
The word node of secondary selection preset quantity, using the corresponding word of word node selected as keyword.
Step S306 searches the corresponding center of each keyword in each keyword set from preset center set of words
Word obtains center set of words, using centre word each in the set of words of center as corresponding first user tag of active user.
Specifically, one social networks map (igraph) of building in advance, social networks map for descriptor and word it
Between relationship, the corresponding centre word of keyword is then obtained from social networks map using Random Walk Algorithm, wherein center
Word refers to the center contacted between word and word in social networks map, such as " menstruation;Dysmenorrhea;Menstrual period;Big aunt;Physiology phase;Month
Menstrual period;Irregular menstruation;Menstrual blood;Dysmenorrhoea;Official holiday;The onset of ovulation;The corresponding centre word of aunt ... " is " menstruation ".In the present embodiment
In, for each keyword, primary iteration word node x, walk for the first time long λ and control are set in social networks map in advance
Precision ∈ (terminating for control algolithm, a very small positive number) processed.Obtain default iteration control times N and current iteration time
Number K, when current iteration number is less than given the number of iterations, that is, K < N when, the random N-dimensional generated between one (- 1,1) to
