Specific embodiment
Below in conjunction with attached drawing, an exemplary embodiment of the present invention will be described, including the various of the embodiment of the present invention
Details should think them only exemplary to help understanding.Therefore, those of ordinary skill in the art should recognize
It arrives, it can be with various changes and modifications are made to the embodiments described herein, without departing from scope and spirit of the present invention.Together
Sample, for clarity and conciseness, descriptions of well-known functions and structures are omitted from the following description.
It should be noted that the embodiment of the present invention is suitable for online service mild-natured, such as shopping, tourism, food and drink, video
Water conservancy diversion etc..Provided object include but is not limited to be video, food and drink, commodity etc., for example, (for example, 30 in predetermined amount of time
It) restocking for the first time sale (abbreviation restocking later) new commodity (abbreviation new product later).For the object repeated, for example, it is heavy
The commodity of multiple restocking, to reduce the influence to online service order, the present invention is not considered herein.
Referring to Fig. 1, thus it is shown that a kind of broad flow diagram for the method for extracting characteristics of objects provided in an embodiment of the present invention,
Include the following steps:
S101: the characteristic information of object in predetermined amount of time is obtained；Wherein, characteristic information includes at least fisrt feature information
And second feature information.
S102: carrying out word segmentation processing to fisrt feature information, according to the quantity of word each after participle and scheduled the
One Feature Words extracting rule, determines the Feature Words of object.
S103: rule is determined according to second feature information and scheduled object value, determines object in pair of current time
As value.
S104: being at least based on Feature Words and object value, generates and the associated mark sheet of object.
In above embodiment, for step S101, each object has its creation time, it is possible thereby to extract predetermined
The object of (for example, 30 days) in period, such as extract the quotient of restocking for the first time and shelf life within certain time limit in commodity library
Product, to prevent the commodity of restocking for a long time from still occurring in new product the selection result.
In addition, the characteristic information of object includes but is not limited to be creation time, identification information, description information etc..It is obtaining
It while characteristic information, needs to judge whether object meets judgement demand, i.e., whether is specified desired object.It is with new product
Example, judge that commodity for the mode of new product, can be judged according to merchandise news, the merchandise news include but is not limited to be commodity
Description information, commodity ID, commodity shelf life.Its specific judgement can be just like under type:
(1) stabbed and judged according to the creation time of object: each object has respective creation time to stab, such as
2018.01.02 restocking commodity A, hereafter object changes (for example, restocking after commodity elder generation undercarriage) anyway, this timestamp is
Constant；
(2) according to the identification information judgment of object: each object has respective identification information, which can deposit
It is stored in object information library, can't change.Match if being inquired in object information library less than with object id information
Information when, it may be determined that the object creates for the first time, for example, the new product of restocking for the first time；For modifying the object uploaded again after deleting
(for example, the commodity for repeating restocking), identification information is constant, and presence can be inquired in object information library；
(3) judged according to the description information of object: object on line has relevant description information, which can be with
It is picture, title, introduction etc., and these description informations and the object composition generate a data, are stored in object information library.
For newly created object (for example, the commodity for repeating restocking) identical with original object, if its description information and object information
The similarity of Reassessment information in library exceeds certain similarity threshold, for example, similarity is greater than 90%, can be confirmed and has deposited
In history object similar with the object, which is not considered.
Wherein, judged according to the similarity of object factory information, it can be just like under type:
1) text description comparison: segmenting text description information, judges between word (participle minimum unit) set
Multiplicity, such as after participle " winter money one-piece dress " and " one-piece dress winter money " there is it is highly similar；
2) image comparison: what is generallyd use at present is to extract finger image first to be compared again.For example, by picture normalizing
Change to same size (for example, 1250 pixels), extracts pixel value from specific pixel, the picture with other image same positions
Element carry out pixel value comparison, the identical quantity of statistical pixel, when quantity exceed predetermined quantity threshold value (for example, 10), can be true
The two fixed objects are similar.
For step S102, for acquired object, before determining Feature Words, can to its fisrt feature information into
Row participle operation, word segmentation processing can be just like under type:
(1) object created in predetermined amount of time is chosen, determines corresponding fisrt feature information, such as its description letter
Breath, generic etc.；
(2) according to the search fields such as title, description, category, brand name, store name, type, for the fisrt feature of object
Information carries out word segmentation processing, multiple words after being segmented；
(3) according to the weight size of different search fields, such as title > description > type, the word after participle is arranged
Sequence generates word set.
By taking predetermined amount of time is 30 as an example, for identified object, a word set is generated daily with creation time；It
Afterwards, the word set for counting all objects in the time limit, multiple word will occurs and is counted and normalized, to reduce background service
Operating pressure, it is final to merge one total word set of generation, statistical distribution is improved compared with single word set, reduces the heat of single object
Degree ratio.
It should be noted that within the time limit of being in certain due to the different and determining object of the creation time of each object, because
This, will not change for the single word set of predetermined amount of time, but for total word set, can occur therewith with the change of time
Variation.
For the word set of object, the Feature Words that can wherein embody characteristics of objects can be extracted, which includes but unlimited
Then such as under type:
(1) determine that the high frequency words in characteristic information, i.e. frequency of occurrence are characterized word, example beyond the word of pre-determined number threshold value
Such as, " ankle boots "；
(2) for the object just created, temperature (concerned degree) is gradually smaller with the growth of shelf life, when
When reaching intended duration, it may be determined that it is no longer new object.Therefore, each word can be calculated according to certain damped expoential
Decay fraction determine word of the gross score beyond predetermined score threshold value for spy with this cumulative gross score for obtaining each word
Levy word.
It,, can also be according to the second spy of object in addition to extracting Feature Words for identified object for step S103
Reference breath carries out scoring operations to it, for example, creation time, history log information etc., convenient for according to score value to the object into
Row sequence.It specifically can be just like under type:
1) from after Object Creation, user gives a mark to its positive rating；
2) it is given a mark according to the clicking rate of object, buying rate；
3) it is given a mark according to the temperature of object (that is, concerned degree)；
4) it is given a mark according to the temperature of object generic；
5) it is given a mark according to the download of platform where object, clicking rate.
Temperature due to object etc. can be gradually decreased with the growth of its shelf life, and its click volume, buying rate etc.
It can be gradually increased with the growth of its shelf life, therefore, for aforesaid way, can be used in combination, can also individually make
Herein with no restrictions with, the present invention.
In addition, a field of the object value as object record, can show with object being incremented by for time and be changed, when right
When reaching intended duration as display, it is no longer new product that its object value, which is returned behind 0, such as New Arrivals 30 days,.
It is right that object-Feature Words-can be generated after the Feature Words and object value for determining object for step S104
As the mark sheet of value, which can change therewith with the variation of time, therefore, can cover update for mark sheet.In addition,
Can also frequency of occurrence, the size of object value etc. according to Feature Words, according to sequence from big to small, for pair in mark sheet
As being ranked up.
Further, object-Feature Words-object value label can also be generated, and adds the label into characteristics of objects.By
Change in Feature Words and object value with object shelf life, therefore the label can cache, and can also change over time
Substitution updates, and the present invention is herein with no restrictions.
Method provided by above-described embodiment, provide it is a kind of extract characteristics of objects thinking, by characteristic information into
Row Feature Words extract and object value determines, generate mark sheet associated with object and are mentioned with the multidimensional characteristic of this conservation object
The accuracy that high characteristics of objects is extracted.In addition, since Feature Words and object value can be gradually changed with being incremented by for time, because
This, gained mark sheet can more fully demonstrate Properties of Objects and the concerned degree from after creating, and more meet the change of its temperature
Law.
Referring to fig. 2, a kind of optional method flow signal for extracting characteristics of objects according to an embodiment of the present invention is shown
Figure, includes the following steps,
S201: the characteristic information of object in predetermined amount of time is obtained；Wherein, characteristic information includes at least fisrt feature information
And second feature information.
S202: carrying out word segmentation processing to fisrt feature information, according to scheduled first decay formula, determines each after segmenting
First pad value of word extracts the Feature Words that word of first pad value beyond predetermined drop threshold is object.
S203: rule is determined according to second feature information and scheduled object value, determines object in pair of current time
As value.
S204: being at least based on Feature Words and object value, generates and the associated mark sheet of object.
In above embodiment, step S201, S203, S204 can distinguish step S101, S103, S104 shown in Figure 1
Description, details are not described herein.
In above embodiment, for step S202, shopping platform increases the temperature of object with shelf life on line
Situation of change, usually rapid decay early period, later period decay at a slow speed.The situation is similar to the decaying that internet hot spots F.F. goes out fastly
Trend, therefore the phase mode that declines can be used, each word of its object is extracted, which includes but is not limited to be
Linear attenuation, half-life period decaying.The present invention mainly uses half-life period damped manner；Wherein, half-life period is characterized the reduction of word score
For the time needed for original half, length of time can reflect the rate of decay of object.
Specifically, the first decay formula can be following formula:
M=M* (1/2) ^ (t/T)
According to the frequency of occurrence of each word in word set, the first pad value of each word is calculated, such as each word daily
The first pad value m, with Feature Words dimension then was carried out cumulative summarize to 30 days scores；Wherein, M is that initial time object is special
Levy the first foundation value of word, such as 100；T is the reaction time, corresponding to the time of object restocking in intended duration, such as 1
~30 days；T is half-life period, such as 7 days.
Citing is specifically described below:
For example, the same day newly creates 3 objects, respective characteristic information is obtained, and fisrt feature information is divided respectively
Word operation, obtains:
Object 1:ABCD
Object 2:CDEF
Object 3:ADE
The number that each word occurs is counted, is obtained:
A:2 times；B:1 times；C:2 times；D:3 times；E:2 times；F:1 times
Above-mentioned word input half-life period formula is calculated, score K1 of each word on the day of is obtained；
If the statistics of yesterday are as follows:
A:3 times；B:2 times；C:1 times；G:1 times；
Due to the growth of shelf life, the word of yesterday need to be inputted in half-life period formula and carry out decay calculation, obtained
Score K2 (K1* decaying number)；
Successively analogy can be intended to 0 for the pad value that the same day is calculated, if but the word in daily newly created object
In occur again, then the word is no longer intended to 0, therefore 30 days pad values are merged, and daily pad value is according to restocking
Time is calculated.
Further, for online shopping platform, the object created for the first time counted on daily may be ten hundreds of, because
This obtained Feature Words quantity is more, to mitigate background service operating pressure, is inputting its frequency of occurrence to half-life period formula
Before, it can be normalized first, for example, compression number is between 1~100.
The corresponding relationship of " word-pad value " is calculated through the above steps, and according to the size order of pad value, rejecting declines
