Document classification in interaction platform is to specified network interaction platform, so as to be the money between homogeneous network interaction platform
Integrate and lay a good foundation in source.The idiographic flow schematic diagram of this method is as shown in figure 1, comprise the steps：
Step S11：Each document under each series of given level in network interaction platform is specified in acquisition
Heading message.
Specified network interaction platform mentioned here be it is relative with for objective network interaction platform, objective network
Interaction platform refers to the platform that resource is integrated, and specified network interaction platform refers to receive the platform reallocated resources.
For example, when by the resource consolidation of first network game platform to second network game platform, first network game platform
For objective network interaction platform, while second network game platform is to specify network interaction platform.In addition, for
The type of network interaction platform and objective network interaction platform is specified not limit herein, that is to say, that it
Can be network electric business platform, network game platform etc..
In network interaction platform, for convenience user find need resource, it usually needs by resource according to
Certain standard is divided into multiple series, and these series can also include multiple different grades.Example
Such as, in network electric business platform, first-level class classification includes books, phonotapes and videotapes, electronic apparatus and household building materials etc.；
Wherein the books, phonotapes and videotapes of first-level class classification, includes secondary classification classification children's book, musical instrument etc. again.Specify
The series of grade can be one-level classification or two grades of classifications or leaf classification,
It can be the series for the other grades specified.The series of the given level is excellent in actual applications
The scheme of choosing can be one-level classification and/or leaf classification, and wherein leaf classification refers to flat in specified network interaction
The subclassification classification of series least significant end in platform, that is to say, that do not have in this specifies network interaction platform
The leaf classification is continued into downward subdivision.
In network interaction platform, various resources are generally embodied in server end in the form of document.For example,
On network electric business platform, for each commodity in the generally all respective corresponding document of service end, a commodity
Corresponding document includes Document Title, and the description information of the classification of the commodity classification, and the document are existed
Address on network.
It can be obtained by this step in specified network interaction platform, under each series of given level
Each document heading message.
Step S12：By the heading message of each document, determine that each series difference is corresponding each
The weight point of keyword and each keyword under correspondence series.
Herein, the weight point be used to assess where by keyword series and the series it
Discrimination when outer other series make a distinction, the keyword refers to the corresponding classification of the keyword
Class is now according to the specified word of pre-defined rule.
This step can be handled by the heading message of each document by the title to these documents,
Determine that each series distinguishes the weight of corresponding keyword and these keywords under correspondence series
Point.The title of document is handled in actual applications, determines that each series distinguishes corresponding keyword
Method can include it is a variety of, a kind of preferred scheme is as shown in step 121.
Step 121：The title of each document is normalized；To each institute after normalized
The title for stating document carries out cutting word processing and entity word identification, obtains the entity word for describing entity things；
Determine that each series distinguishes the word frequency of corresponding each entity word, the word frequency of entity word is used to describe described
The times or frequency that entity word occurs in the corresponding series；Using each entity word as
Current entity word, judges whether the word frequency of the current entity word is more than predetermined threshold value, if so, then will be described
Current entity word is defined as the keyword of corresponding series.
Normalized can include in actual applications letter it is big first write conversion, traditional font and simplified conversion and
Tense conversion etc..Title progress cutting word processing to document can generally use tokenizer, conventional cutting word
Instrument has word2vec.Entity word identification can generally be completed by entity dictionary, and entity word refers to description
The word of entity things, such as trade name, trade mark, title, game name.After entity word identification,
The word frequency of each entity word under each series is counted respectively；Then by comparing the word frequency of these entity words
With the size of predetermined threshold value, word frequency is selected more than predetermined threshold value entity word as the corresponding classification of the entity word
The keyword of class now.For example, 3 entity words under electronic apparatus series be respectively " computer ",
" mobile phone " and " charger ", wherein the word frequency of " computer " is 300, the word frequency of " mobile phone " is 350, " is filled
The word frequency of electrical equipment " is 100, and predetermined threshold value can be set according to actual needs, if predetermined threshold value is set to 200,
Then " computer " and " mobile phone " will be confirmed as keyword under the electronic apparatus series.
It should be noted that in order to avoid under some series in step 121, word frequency highest entity
The word frequency of word is again smaller than predetermined threshold value, so that the series is excluded.Therefore when some classification of appearance
In classification, the word frequency of word frequency highest entity word again smaller than predetermined threshold value situation when, can be by suitably reducing
The mode of predetermined threshold value to solve.Certainly, it is a kind of preferred when there is such case in actual applications
Scheme is, when the word frequency of the corresponding each entity word of current class classification is respectively less than predetermined threshold value, described will work as
The maximum entity word of word frequency is defined as the keyword in the current class classification in preceding series, described to work as
Preceding series includes any one series in each series.For example, musical instrument series
Lower word frequency highest entity word is " guitar ", and the word frequency of " guitar " is 86 under the series, if in advance
If threshold value is 100, in order to prevent musical instrument series to be excluded, " guitar " can be defined as to musical instrument point
The keyword of class class now.
In fact, it should be noted that first can also be cut to the title of each document in step 121
Word processing, then the result after cutting word is normalized and entity word identification, so as to obtain being used to retouch
State the entity word of entity things.
Weight point of each keyword under correspondence series can also be determined in step 12, can be direct
Using word frequency of each keyword under correspondence series as weight point, it can also determine by other means
Weight point.In actual applications, a kind of preferred scheme for determining keyword weight point under correspondence series
As shown at 122.
Step 122：Determine word frequency of the keyword in corresponding series；Pass through each classification
The number of files and each series of the keyword are included in the title of each document of class now hereafter
The sum of shelves, determines the anti-document frequency of the keyword；By the keyword in corresponding series
In word frequency and the keyword the anti-document frequency determine the keyword correspondence series
Under weight point.
In step 122, in order to determine some keyword weight under corresponding series point, first really
Fixed word frequency (Term Frequency, TF) of the keyword under corresponding series；It is then determined that each
In the title of each document under individual series under number of files n and each series comprising the keyword
Document total N, and determine by n and N anti-document frequency (the Inverse Document of the keyword
Frequency, IDF)；Finally by word frequency under correspondence series of the keyword and the keyword
Anti- document frequency determines weight point of the keyword under correspondence series.
In actual applications, the anti-document frequency of the keyword can be determined by following formula：
IDF=log (N/n)
Wherein, N is the sum of the document under each series, and n is each document under each series
Title in include the number of files of the keyword.Log (N/n) refers to take the logarithm to N/n value, the logarithm
Bottom can be set according to actual needs, in actual applications log (N/n) typically natural logrithms
ln(N/n)。
In actual applications, weight point of the keyword under correspondence series can pass through, by the keyword
Word frequency under correspondence series is multiplied with the anti-document frequency of the keyword to be obtained.
Step S13：Corresponding each keyword is distinguished according to each series, each series
And the weight of each keyword is mitogenetic into dictionary.
According to distinguishing each corresponding keyword under each series, each series and each is crucial
Correspondence series under weight it is mitogenetic into dictionary.Keyword, classification class can be included in the dictionary
Three attribute items of mesh and weight point.
It is a kind of generate dictionary preferred scheme be, using each keyword as current key word, according to
The current key word, the corresponding series of the current key word and the current key word exist
Weight under correspondence series is mitogenetic into associated group；According to each associated group generation dictionary.
The word stock generating method provided using embodiment 1, is obtained and specifies given level in network interaction platform
Each series under each document heading message, by the heading message of each document, determine each classification class
Mesh distinguishes the weight point of corresponding each keyword and each keyword under correspondence series, then according to each
Series, each series distinguish corresponding each keyword and the weight of each keyword is mitogenetic into word
Storehouse.This method is used for by the dictionary of each document structure tree under each series in specified network interaction platform
By the document classification in objective network interaction platform to specified network interaction platform, so as to be homogeneous network interaction
Resource consolidation between platform is laid a good foundation.
In order to make it easy to understand, the embodiment of the present application is additionally provided under a kind of practical application scene, implement described

Embodiment 2
Embodiment 2 provides a kind of Document Classification Method, and this method utilizes the dictionary that embodiment 1 is generated, will
Document classification in objective network interaction platform is to specified network interaction platform, so as to solve existing due to dividing
The difference of class standard, the problem of being difficult to resource consolidation between homogeneous network interaction platform.This method
Idiographic flow schematic diagram is as shown in figure 3, comprise the steps：
Step S31：Obtain the heading message that document is specified in objective network interaction platform and determine described specify
The corresponding each entity word of title of document, the entity word is used to describe entity things.
Objective network interaction platform mentioned here refers to the platform that resource is integrated.For example, by first network
When the resource consolidation of gaming platform is to second network game platform, first network game platform is that objective network interaction is flat
Platform.In addition, the type for objective network interaction platform is not limited herein, that is to say, that they can
To be network electric business platform, network game platform etc..
In network interaction platform, various resources are generally embodied in server end in the form of document.For example,
On network electric business platform, for each commodity in the generally all respective corresponding document of service end, a commodity
Corresponding document includes Document Title, and the description information of the classification of the commodity classification, and the document are existed
Address on network.Specified document refers in objective network interaction platform, it is necessary to be integrated into specified network
The corresponding document of resource in interaction platform.
By specifying the heading message of document, determine that this specifies each corresponding entity word of title of document, institute
Stating entity word is used to describe entity things, such as trade name, trade mark, title, game name.
In actual applications, by specify document title, determine this specify document title it is corresponding each
The method of entity word has a lot, and a kind of preferred scheme is as shown in step S311.
Step S311：The title of the specified document is normalized；To the institute after normalized
The title for stating specified document carries out cutting word processing and entity word identification, determines the title pair of the specified document
Each entity word answered.
Normalized can include in actual applications letter it is big first write conversion, traditional font and simplified conversion and
Tense conversion etc..Cutting word processing is carried out to the title for specifying document can generally use tokenizer, conventional
Tokenizer has word2vec.Entity word identification can generally be completed by entity dictionary.Know in entity word
After not, the word frequency of each entity word under each series is counted respectively；Then by comparing these entity words
Word frequency and predetermined threshold value size, select word frequency more than predetermined threshold value entity word as the entity word correspondence
Series under keyword.
The entity word determined by step S131, due to be normalized and entity word identification, because
This more accurate and standardization.
Step S32：By inquiring about dictionary, each series of each entity word in the dictionary is determined
Under weight point.
The dictionary is the dictionary of the word stock generating method generation provided according to embodiment 1.Lead in the dictionary
Often include keyword, series and weight point three attribute items, wherein, weight point is used to assessing will
Discrimination when series makes a distinction with other series outside the series where keyword,
Keyword refers under the corresponding series of keyword according to the specified word of pre-defined rule.
By inquiring about the dictionary, determine that each entity word is corresponding respectively under each series of the dictionary
Weight point.In actual applications, it will usually which appearing in does not have the entity word to be searched under some series
Situation, at this time weight of the entity word under these series can be divided into predetermined constant, lead to
The normal predetermined constant can be 0.For example, entity word is " rice ", in the series " computer " of dictionary
Do not occur the entity word below, therefore the weight of " rice " under the series can be set up separately and be set to
Preset constant.
Step S33：By each entity word weight under each series point, the finger is determined
Determine document respective total score under each series.
This step is used to determine that this specifies document respective total score under each series of dictionary, with this
Illustrate the determination process of total score exemplified by specified total score of the document under one of series of dictionary,
The series is called current class classification herein.Generally each reality in Document Title can be specified by this
The weight of pronouns, general term for nouns, numerals and measure words respectively in current class classification point, determines that this specifies document in current class class now total
Score.
In actual applications, each entity word is specified in Document Title respectively in current class classification by this
Weight point, determine that this specifies the mode of total score of the document in current class class now to have a variety of.For example,
The weight of each entity word point can be weighted summation, determine the specified document in current class class now
Total score, the wherein weights of entity word can determine according to the entity word own type, entity word itself class
Type has title, place name, brand word etc.；Can also using each series as current class classification,
Summed by the weight point by each entity word in the current class class now, determine described specify
Total score of the document in the current class class now.
Step S34：By the specified document, respective total score refers to described under each series
Determine document to be classified.
It is determined that this specifies document under each series after respective total score, by each classification class
Now respective total score is to specifying document to classify.
It is this under each series respective total score to specify document classify by way of have
It is a variety of.For example, can be arranged according to the size order of total score, this is specified into document classification to must
Under point maximum series, namely by the specified document is respective under each series must
Point, determine the maximum total score series corresponding to the maximum total score of the specified document and refer to described
Document classification is determined to the maximum total score series.
Further, the problem of would generally encountering various in actual applications, therefore passing through total score
Classification is may result in when being classified not accurate enough.For example, Document Title is " apple iphone4s data
Line ", the entity word after the document title is split includes " apple ", " iphone4s " and " data wire ", by
It is higher in " apple " and " iphone4s " the two entity words weight under series " mobile phone " point,
Normally result in and be categorized into the document under " mobile phone this " series.Therefore, such as Fig. 4, Yi Zhongtong
The respective total score under each series is crossed, to the preferred scheme such as step for specifying document to be classified
Shown in S341 to step S345.
Step S341：By each series according to the specified document the total score from high to low
Queue is sequentially generated, the classification of predetermined quantity is chosen according to the order in queue from the original position of the queue
Classification.
The series of the predetermined quantity at least includes two series, in actual applications generally can be with
Multiple series are chosen as needed, for example, choose total score 100 series of highest successively.
Step S342：Obtain initial classification of the specified document in objective network interaction platform.
Due to this in objective network interaction platform specify document belonging to initial classification in, generally also can comprising pair
This specifies the useful information of document classification, therefore can obtain the specified document in objective network interaction platform
