Description
Technical field
The invention belongs to natural language processing technique field, is related to a kind of side that automatic Calibration is carried out to word emotion value
Method.
Background technology
The present invention is a kind of method for aiding in automatic sentiment dictionary to create, and an outstanding sentiment dictionary can be many feelings
The effect of sense analysis application provides safeguard.Substantial amounts of people is needed due to sentiment dictionary create using artificial method at present
Power material resources and time, therefore, creating sentiment dictionary using automatic method becomes inevitable choice.
" sentiment analysis " is related to the problem of many difficult, and there is certain contact between these problems.As a rule,
These problems are typically all the emotion value for needing to automatically detect that text, and it is positive or passive to identify this text
, or without Sentiment orientation.Moreover, with the fast development of online network social intercourse service, anyone may be used on network
With by a microblogging, push away text, or a circle of friends to express oneself view to a certain part thing, to certain the same thing
Happiness dislike.These emotion informations are very important resource and business opportunity for service provider and advertiser, major social activity
Network company sets up special segment analysis and the microblogging that excavation user delivers and pushes away emotion trend information and the user in text
Viewpoint information.Sentiment analysis technology how is improved, and then improves the degree of accuracy and the efficiency of analysis emotion information, becomes a weight
Want developing direction.On the other hand, not only need to use outstanding algorithm to be analyzed, it is more crucial and basis to be the need for one
Generally acknowledged can accurately give expression to the emotion method for expressing distinguished between all kinds of emotions.In emotion information analysis, in general
There is the method that two kinds of emotions represent, be discrete classification type method for expressing and continuous dimension type method for expressing respectively.The former allusion quotation
The representative of type has binary classification method for expressing, and emotion is simply divided into two kinds of positive and passive classifications；Also Robert
Eight yuan of basic emotional semantic classifications that Plutchik is proposed, eight class emotions are happy, sad, angry, frightened respectively, detest, be surprised, letter
Appoint and expect.Sentiment analysis application based on this emotion method for expressing has such as extraction of spam detection, viewpoint and viewpoint
Identification etc. has high actual application value and development prospect.
Continuous dimension type emotion method for expressing has equally attracted substantial amounts of concern in recent years.Compared to the expression of classification type
Method, the method for expressing of dimension type can allow sentiment analysis more accurate and careful.Because the sentiment analysis of dimension type can lead to
Various dimensions emotion value is crossed to represent the emotion expressed by a word, the emotion of such a word can be with use unique one
Individual coordinate represents, even express the word of close emotion.For example, in VA (Valence-Arousal；Mood value-excitation
Value) two-dimentional emotional space, as shown in Figure 1 in, the V values of the two words of " happiness " and " mad with joy " --- representative is positive or disappears
The degree of pole --- will be very nearly the same, and representing the A values of emotion intensity can then have a long way to go.
On the premise of this kind of dimension type emotional space, the task of sentiment analysis be usually to word, sentence either
Text carries out the demarcation of emotion value.Also, the emotion value for carrying out sentence and text is demarcated generally based on the emotion value of word.
Therefore, it is essential to demarcate excellent sentiment dictionary.Complete the method for this task from big classification for have two kinds,
One of which method is by manually demarcating, and in general flow is to allow different demarcation personnel to some word according to certainly
Oneself judgement demarcation emotion value, the processing further according to the progress of proprietary calibration result necessarily mathematically afterwards, so as to draw this
The final emotion value of individual word.The cost so done is to need substantial amounts of manpower and time, with high costs.Another method is logical
Cross the demarcation that computer automatically carries out emotion value using the method for machine learning.However, for this task, use
Machine learning algorithm is typically all the algorithm for having supervision, and this requires the sentiment dictionary established in advance and provides training for algorithm
Collection.
Generally acknowledge that the higher sentiment dictionary of degree has at present：ANEW (the Affective Norms for English of English
Words), comprising 1034 English words for being labelled with VA values；Chinese CAW (Chinses Affective Words) and
CVAW (Chinese Valence-Arousal Words), the English for being labelled with VA values comprising 162 and 1653 respectively are single
Word, other outstanding sentiment dictionaries do not enumerate.These sentiment dictionaries are the bases for realizing automatic marking sentiment dictionary.
Wei and Malandrakis et al. have used several methods based on recurrence to carry out emotion before and after 2011
Value prediction.These methods are typically used as training set (kind sub-word by sentiment dictionary；Seed words), train corresponding mould
Type, emotion value demarcation is carried out to the word (unseen words) for not demarcating emotion value by the model again afterwards.Such emotion
It is worth Forecasting Methodology, the accuracy of prediction result is low.
The content of the invention
To achieve the above object, the present invention provides a kind of method that automatic Calibration is carried out to word emotion value, avoids a large amount of
Using artificial demarcation, the accuracy of emotion value prediction result is high, solves the prediction knot of emotion value Forecasting Methodology in the prior art

In embodiment, the every other implementation that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example, belongs to the scope of protection of the invention.
Google PageRank algorithms are to calculate Web page importance and accordingly to the algorithm of webpage progress ranking, the algorithm
Purpose be to recommend the webpage the most similar to user's search result for user.The core concept of PageRank algorithms has following two
Bar：First, if a webpage illustrates that this webpage is important by a lot of other web page interlinkages if, that is,
PageRank value can be of a relatively high；Second, if the very high web page interlinkage of a PageRank value is to other webpages, then quilt
Therefore the PageRank value for the webpage being linked to can be improved correspondingly.
According to the principle of PageRank algorithms, the method for another emotional semantic classification is also suggested, and such method is to pass through
The distance for judging emotion value word to be calibrated and planting " relation " between sub-word demarcates emotion value, when two words have it is close
" relation " when, their emotional category should also be as being similar, by such method come the list to not demarcating emotional category
Word carries out emotional semantic classification.The core of this method be on a figure using label propagate (Rao and Ravichandran,
2009；Hassan, 2011) and PageRank algorithms (Esuli, 2007).But this method is presently mainly to be used in emotion
Category division on.
The present invention has carried out the improvement of following two aspects to PageRank algorithms so that it can be used in emotion value
(VA) in prediction；Is that Rank scores are converted into specific VA values on one side, and VA values include mood value and excitation value, see figure
1；Second aspect, the weight on the side between word to be calibrated in PageRank algorithms and the kind sub-word of its adjoining is regarded as phase
Together, using the similarity between word to be calibrated and the kind sub-word of adjoining as the side between two nodes in weight graph model
Weighted value, consequently, it is possible to which the adjacent kind sub-word higher with word similarity to be calibrated is demarcated in the emotion value of word to be calibrated
Middle contribution is much, and shared weight is bigger, i.e., consider simultaneously word to be calibrated and each adjacent relation planted between sub-word and with
Similarity between each adjacent kind sub-word.
The method that automatic Calibration is carried out to word emotion value, is specifically followed the steps below：
Step 1, the term vector of all words in dictionary is trained, a small amount of word is initialized by the method for handmarking,
It is denoted as kind of a sub-word vj, remaining word is word v to be calibratedi；The kind sub-word v being initialisedjMood value be valvj, excitation
It is worth for arovj；
Step 2, each kind sub-word v is calculated using word2vec instrumentsjWith each word v to be calibratediTerm vector between
Cosine angle value, obtain each kind of sub-word vjWith each word v to be calibratediBetween similarity；
Step 3, with kind of a sub-word vjWith word v to be calibratediAs node, with kind of a sub-word vjWith word v to be calibratediIt
Between similarity as even side right weight, build weight graph model；
Step 4, word v to be calibrated is predictediMood value valviWith excitation value arovi。
It is theoretical according to link analysis, the relational model of sub-word and word to be calibrated is planted, as shown in Figure 2.Word to be calibrated
Emotion value can be demarcated according to the VA values of similarity highest word in adjacent kind of sub-word.Word to be calibrated and its neighbour
The weighted value (i.e. similarity) on the side between inoculation sub-word is calculated by the Google word2vec instruments provided；Calculate
Similarity between cosine angle value between the term vector of two words, as two words.The mathematical expression of graph model is such as
Under：Non-directed graph G=(V, E), wherein, V represents the node of the set, i.e. figure of word, and E represents the side of undirected connection between node
Set.Every a line e in E represents word v to be calibratediWith kind of a sub-word vjBetween similarity (vi,vj∈V(1≤i,j≤
n；i≠j)).For each word v to be calibratedi, its adjoining seed set of letters is expressed as N (vi)={ vj|(vi,vj)∈
E}.Word v to be calibratediValence values (mood value) and Arousal (excitation value) use respectivelyWithRepresent, treat
Demarcate word viMood value valviComputational methods such as formula (1) shown in：
Word v to be calibratediExcitation value aroviCalculated according to formula (2)：
Wherein, valvjRepresentative species sub-word vjMood value, Sim (vi,vj) represent word v to be calibratediWith kind of a sub-word vj
Between similarity.α is decay factor or confidence level, and value can limit the row in PageRank algorithms between 0-1
Influenceed caused by name sinkage, the phenomenon can cause result can not converge unique value；When at the beginning, word v to be calibratedi
VA values be random number, any number being initialized as between 1 to 9, then pass through formula (3) and formula (4) constantly iteration afterwards and update
To convergence.
Wherein, t represents the step number of iteration；WithT step iteration word v to be calibrated is represented respectivelyiMood value
valviWith excitation value arovi, similarlyWithT-1 step iteration word v to be calibrated is represented respectivelyiMood value valvi
With excitation value arovi。
It is worth noting that, the VA values of kind sub-word are all a constant in the iteration of each step, do not change.It is based on
This, the VA values of each word to be calibrated are propagated up to convergence by successive ignition in fig. 2 and got.
In order to improve the efficiency of iteration, formula (3) and formula (4) can be improved as matrix operation.By all words to be calibrated
Following two vector representations are merged into the mood value valence and excitation value arousal of kind of sub-word：WithIf all words to be calibrated and kind sub-word
Between similarity may make up adjacency matrix：
Wherein, Sim (vi,vj) represent word v to be calibratediWith kind of a sub-word vjBetween similarity, i ≠ j, 1≤i ＜ N, 1
≤ j ＜ N.Give two vectorial I=(1,1,1 ..., 1) again simultaneouslyTWith D=(d1,d2,...,dN)T, wherein,α is the decay factor in formula (3) and formula (4)；Re-define two computings, it is assumed that to
Measure X=(x1,x2,...,xN)T, vectorial Y=(y1,y2,...,yN)T, then functional operation M (X, Y)=(x1×y1,x2×y2,...,
xN×yN)T, functional operation U (X, Y)=(x1/y1,x2/y2,...,xN/yN)T；
Using formula (5) calculate mood value that t step iteration includes all vocabulary including kind of sub-word and word to be calibrated to
Measure VtWith excitation value vector At；
Vt=M [(I-D)T, Vt-1]+M[DT, U (SVt-1, S × I)],
At=M [(I-D)T, At-1]+M[DT, U (SAt-1, S × I)] (5)
Wherein, Vt-1Represent t-1 step iteration and include kind of a sub-word vjWith word v to be calibratediThe mood of all vocabulary inside
Value vector, At-1Represent t-1 step iteration and include kind of a sub-word vjWith word v to be calibratediThe excitation value vector of all vocabulary inside；
After successive ignition convergence, according to mood value vector VtIndex obtain word v to be calibratediMood value valvi, according to excitation
It is worth vectorial AtIndex obtain word v to be calibratediExcitation value arovi；Word v i.e. to be calibratediMood value valviFor mood value
Vectorial VtI-th dimension respective value；Word v to be calibratediExcitation value aroviFor excitation value vector AtI-th dimension respective value；Such as
Word v to be calibrated2Mood value be mood value vector VtSecond dimension respective value；Such as word v to be calibrated3Excitation value be sharp
Encourage the vectorial A of valuetThird dimension respective value.
By formula (5), the prediction of VA values can be with more efficient iteration convergence.
The calibration result of the present invention is tested using ANEW English sentiment dictionary and CAW Chinese sentiment dictionary；In reality
During testing, we are tested using cross validation.Specific operation is that data set is equally divided into several pieces, is divided in experiment
For 5 parts；Often once tested, be used as word to be calibrated using 4 parts therein as kind of a sub-word, remaining portion, so follow
Ring is tested 5 times, and final result takes the average value of each experimental result.
Meanwhile we are provided with two groups of contrast experiments；The method that first group of VA value using homing method is predicted, including line
Property regression algorithm and kernel function regression algorithm.For first group of two methods, plant similarity between sub-word and they
VA values will be trained as training set data, and remaining word is then used as test data.Second group is two kinds and is based on graph model
Method, be PageRank algorithms and weight map model algorithm proposed by the present invention respectively.
Evaluation index：
Mainly weighed for the performance of distinct methods by following three indexs：
Mean square error (Root mean square error, RMSE)：
Mean absolute error (Mean absolute error, MAE)：
Average absolute percent error (Mean absolute percentage error, MAPE)：
Wherein, AiRepresent the actual value of word emotion VA values to be calibrated, PiRepresent the prediction of word emotion VA values to be calibrated
Value.If three indexs of certain method are all than relatively low, then it represents that the predicted value of this method and actual value are closer, this method effect
Well.
Experimental result and analysis：
PageRank algorithms and weight nomography are required to be iterated operation, and we are that two algorithms set identical
Iterative steps are contrasted, and explore the effect of the different iterative steps under current data set, and we are with square mean error amount
As reference, the iteration effect of two algorithms is as shown in Figure 3.
From figure 3, it can be seen that what two algorithms all substantially tended towards stability near the 10th iteration；Weight map of the present invention
Algorithm prediction-emotion value Valence and excitation value Arousal square mean error amount is relatively low, predicted value relatively connects with actual value
Closely；The final convergence result of each word is unrelated with original allocation value and decay factor.
Linear regression is respectively adopted, kernel function recurrence, PageRank algorithms, weight nomography of the present invention tested it is each
Individual index the results are shown in Table 1, and the wherein iterations of PageRank algorithms and weight graph model of the present invention is respectively provided with 50 times.
Each index result of 1 four kinds of algorithms of table
From table 1 it follows that linear regression is generally better than based on PageRank algorithms and weight nomography of the present invention
Algorithm and Kernels.Performance of the weight nomography of the present invention in MAPE (average absolute percent error) this index is excellent
It is average by low about 4%, lower than the kernel function Return Law 8% or so than PageRank algorithm in other three kinds of algorithms, compare linear regression
Method low 7%.The reason for weight nomography does very well than other several algorithms is that it considers relation between multiple nodes simultaneously
And the weighted value between them.In addition, we can also find out from result, for the prediction of Arousal values than Valence values
The difficulty of prediction is big.
Linear regression algorithm：
When the VA values prediction of word to be calibrated is carried out using method automatically or semi-automatically, generally mark in a manual manner
A small amount of emotional words as kind of a sub-word, recycle calculate the method for semantic similarity between word automatically from a large amount of text marks with
The similar word to be calibrated of kind sub-word.
Therefore, the corresponding relation of word " similarity-VA values " can be generally established using linear regression, is then recycled
Similarity between word to be marked and kind sub-word predicts the VA values of word to be marked.Because each kind of sub-word has mark
The VA values remembered, therefore only need to calculate the similarity of each kind of sub-word and other kind of sub-word, can be each seed list
Word establishes the regression model of " similarity-Valence (or Arousal) value ", and following formula is kind of a sub-word seedjValence return
Return model,
Wherein, b is regression coefficient, and a is intercept.Wherein Sim (seedi,seedj) representative species sub-word seediAnd seedj
Semantic similarity,For seediValence values.Therefore, if by seedjWith the similarity of other kind of sub-word with
And Valence (or Arousal) value of these seed vocabulary substitutes into, you can training obtains seedjValence (or
Arousal regression model).
If to predict the word VA values to be marked by checking using this regression model, it is only necessary to by these words with
seedjSimilarity input, such as：Assuming that certain word unseen to be markediWith seedjSimilarity exceed threshold values and logical
When crossing checking, unseeniEmotion vocabulary will be chosen as, now can be by unseeniWith seedjSimilarity input seedjReturn
Return model to predict candiVA values, be shown below,
If both can be used not only more than the threshold values of a kind sub-word in similarity of the word to be marked with planting sub-word
Regression model caused by the maximum kind sub-word training of similarity.
Kernel function regression algorithm：
Based on this, another method can introduce kernel function in the linear regression model (LRM) of routine, for being carried out to similarity
Conversion linearly or nonlinearly, regression model are defined as：
Wherein f represents kernel function, can be the nonlinear function such as linear function or square root, logarithm.Based on this
Individual model, the VA values of word to be markedCan be by the VA values of all kind sub-words similar to itsWith them it
Between semantic similarity Sim (unseeni,seedj) be predicted.It is final test result indicates that, when kernel function is linear function
Best prediction effect can be obtained.
PageRank algorithms：
Also the VA values for having some documents to propose to be carried out vocabulary using PageRank algorithms are predicted.This kind of method is generally by seed
As node, vocabulary and similarity are described as graph model, and introduce by the relation between vocabulary as side for word, word to be marked
PageRank algorithms are solved.In the method, the VA values of each node (word) to be marked are updated according to the following formula：
Wherein, wiAnd wjWord to be marked and kind sub-word, Nei (w are represented respectivelyi) represent and node (word) wiThere is side
The set of connected all of its neighbor node (word).Represent the Valence values prediction of the t times interative computation of word to be marked
As a result, e is a constant, and α is the attenuation coefficient in PageRank algorithms, and usual value is (0,1).Based on formula (12), candidate
The VA values of vocabulary can be predicted by PageRank interative computation using the VA values of seed vocabulary.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the scope of the present invention.It is all
Any modification, equivalent substitution and improvements made within the spirit and principles in the present invention etc., are all contained in protection scope of the present invention
It is interior.
