Those of ordinary skill's all other embodiment obtained without making creative work, belongs to protection of the present invention
Range.
Referring to Fig. 1, a kind of one embodiment of text emotion analysis method may include: in the embodiment of the present invention
Step S101 carries out word cutting processing to statement text to be analyzed, obtains each point that constitutes the statement text
Word.
Word cutting processing, which refers to, is cut into individual word one by one namely each participle for a statement text,
In the present embodiment, cutting can be carried out to statement text according to universaling dictionary, guaranteeing the word separated all is normal vocabulary, such as word
Language does not separate individual character then in dictionary.When front-rear direction can be at word, such as " praying to Gods for blessing ", it can be according to the big of statistics word frequency
Small division, as " it is required that " " it is required that/mind " is separated if word frequency height, " want/pray to Gods for blessing " is separated if " praying to Gods for blessing " word frequency height.
After splitting out each participle, if considering binary combination word, then neighbouring word combination of two can be increased
" celebration meeting ", " conference is smooth ", the binary combinations word such as " smoothly closing ".It preferably, can also be further according to word frequency to these
Binary combination word is screened.Specifically, the frequency threshold for presetting a screening obtains what each binary combination word occurred
Frequency retains the binary combination word if the frequency that some binary combination word occurs is greater than or equal to the frequency threshold, if some
The frequency that binary combination word occurs is less than the frequency threshold, then weeds out the binary combination word, namely be regarded as two independences
Unitary word.If the frequency threshold that we set as 5, rejects all frequency of occurrence in 5 binary combination words below.
Step S102 searches the column vector of each participle respectively in preset term vector database.
The term vector database is the database for recording the corresponding relationship between word and column vector.The column vector can
To be the corresponding term vector according to obtained by word2vec model training word.This is indicated according to the contextual information of word
The probability that word occurs.Each vocabulary is first shown as a 0-1 vector still according to the thought of word2vec by the training of term vector
(one-hot) form, then word2vec model training is carried out with term vector, n-th of word, neural network are predicted with n-1 word
The pilot process obtained after model prediction is as term vector.Specifically, as " celebrations " one-hot vector assume be set to [1,0,
0,0 ... ..., 0], the one-hot vector of " conference " is [0,1,0,0 ... ..., 0], the one-hot vector of " smooth " for [0,0,
1,0 ... ..., 0], predict that the vector [0,0,0,1 ... ..., 0] of " closing ", model can generate the coefficient square of hidden layer by training
Battle array W, the product of the one-hot vector sum coefficient matrix of each word are the term vector of the word, and last form will be analogous to " celebrating
Wish [- 0.28,0.34, -0.02 ... ..., 0.92] " such a multi-C vector.
In the present embodiment, the term vector database can be K grades of tree-shaped fragment storage organizations, then step S102 can be with
Include the steps that as shown in Figure 2:
Step S1021 carries out Hash operation to current participle using multiple mutually independent hash functions.

Specifically, Hash fortune can be carried out to current participle using K mutually independent hash functions respectively according to the following formula
It calculates:
HashKeyk=HASHk(BasicWord)
Wherein, BasicWord is the current participle, HASHkFor the hash function of serial number k, HashKeykIt is obtained for operation
The cryptographic Hash of the serial number k arrived, 1≤k≤K, K are the integer greater than 1.
Step S1022 calculates the serial number of storage fragment at different levels belonging to the current participle.
Specifically, the serial number of the storage fragment of kth grade belonging to the current participle can be calculated according to the following formula:
Wherein, MaxHashKeykFor hash function HASHkMaximum value, FragNumkFor the storage point of kth grade subtree
The number of piece, Ceil are the function that rounds up, and Floor is downward bracket function, and WordRoute is the number in record storage path
Group, WordRoute [k-1] are the serial number of kth grade fragment belonging to the current participle, and are k-th yuan of WordRoute
Element.
Step S1023 searches the column vector currently segmented under the store path of record.
Specifically, i.e., the column vector currently segmented is searched under the store path that array WordRoute is recorded.Example
Such as, if array WordRoute=[1,2,1,3,5], then store path are as follows: storage fragment-> 2nd of the 1st grade of subtree serial number 1
The storage of storage fragment-> 3rd level subtree serial number 1 storage fragment-> 4th grade subtree serial number 3 of grade subtree serial number 2
The storage fragment of fragment-> 5th grade subtree serial number 5 searches the column vector currently segmented under the store path.
Step S103, by the Column vector groups of each participle at input matrix.
Wherein, each column of the input matrix correspond to a column vector, i.e., the Column vector groups of first participle are at institute
Show the first row of input matrix, secondary series ... ... of the Column vector groups of second participle at shown input matrix, n-th participle
Column vector groups at shown input matrix Nth column.N is the number of the participle.
Step S104 chooses a participle corresponding with preset analysis object from the statement text and is used as text feelings
Feel the emotion main body of analysis.
For example, a certain statement text is " company A sales achievement substantially surmounts B company ", wherein there are two emotion main bodys altogether
It is available, respectively " company A " and " B company ", if current emotion class for wanting analysis " company A " in the statement text
Type, i.e., the described analysis object are " company A ", then choose the emotion main body that " company A " is analyzed as text emotion, if current want
The affective style of " B company " in the statement text is analyzed, i.e., the described analysis object is " B company ", then chooses " B company " work
For the emotion main body of text emotion analysis.
The input matrix and input vector are input to preset text emotion and analyze neural network model by step S105
