Description
Technical field
The present invention relates to English Writing analysis field, write more particularly, to a kind of English analyzed based on deep semantic
Make artificial intelligence system.
Background technology
For the development of natural language processing technique, no matter the commercial market of home and abroad, scientific research field, and bigger model
Rapid, accurate, depth analysis requirement always all pole of the human society enclosed for extensive, large-scale real text content
Its is urgent.Technological means of the global scientific and technological circle at present in terms of extensive real text is handled is broadly divided into the nature of (1) early stage
What advanced technology was many before the ratio that language processing techniques (NLP) and (2) are gradually formed for nearest 30 years uses mixing side
The treatment technology for the deep semantic analysis module that method is built.
The natural language processing technique (NLP) of early stage is also unique most prominent in terms of Text extraction the characteristics of
Technical functionality is-computer for big section word semantics recognition.By the technology, computer can recognize a big section words substantially
General idea.Such as a certain big section of literal expression one extremely complex scene and behavior, but pass through the technology, calculate
Machine can recognize that the main information included in fact in this section of words is:In the substantially behavior of some scene and period.The technology is made
To realize identification technology of the computer to text, during the research and use of nearly half a century, mainly it is used in machine and turns over
Translate, information retrieval, and the field such as information extraction, and the increasing application achievements obtained in extensive scope.
For the angle realized from technology, the technology is concentrated mainly in the analysis of morphology and syntax, rule-based mutually to be tied with statistics
The language analysis of conjunction.More there are phrase structure grammar, the vocabulary function that head drives in the syntactic analysis model of maturation at present
The technologies such as grammer, dependency grammar.After integrated a variety of natural language processing techniques, semantics recognition is developing progressively as comparative maturity
Application.
The application of main flow is the highly integrated product of front end speech recognition technology on current commercial market, as known to masses
The Siri of Apple Inc., and the well-known University of Science and Technology's news of domestic contrast fly the semantic identification of the related voice based on the release of this technology and answered
With.
In current semantic analysis spring tide, most of time and energy are all used in the place for natural language (NLP)
In reason, that is to say, that have very much limitation in actual life based on applying for semantics recognition technology.After all, the technology can only be known
The language message on not simple basis, however no matter business circles, educational circles, scientific circles for computerization semantics recognition real demand
The information on simple basis, but text include various dimensions, profound information-and this point are the technologies can not be real
Existing.Various circles of society's widespread demand and earlier technique based on sustainable growth can not meet the demand, the multi-dimensional semantic of higher level
Depth analysis just rises naturally from global scientific research academia.
Thus, according to the deduction of natural language and big data, a kind of pattern is gone into, and derive into one based on structuring
The module of autonomous learning, this process is undoubtedly inaccurate for artificial intelligence writing assistant.Reason has following several
Point, first, it is temporal to waste.This process is the accurate model of a kind of neither one itself, and this method is substantially by big
The fuzzy matching of data, is excavated for data are continuous, finds out similar model, and (either neural by Recognition with Recurrent Neural Network
Netspeak model, or LSTM models) continuous iterative cycles.Do not say first precision can how, light row is into a kind of model
Standard, may be accomplished by taking a period of time.Second, model accuracy.In the age that office software all carries English verification,
Engineering inveterate habit how can be allowed to carry the big data information bank of specific background demand, and check out a kind of new model automatically
It is a difficult thing.For example, how to allow machine to understand the judgment criteria of English composition, and student is drawn by this machine
Model goes to write whether English composition can really write out a complete articleAnswer is negative.Go into seriously reason, that is,
Machine does not have autonomous expert system, such as professional English composition, is to need to understand very much expert's note of this kind of judgment criteria
Enter information model.In this, as foundation stone, dynamic adjustment judgment criteria can be only achieved optimal most accurate judge based on artificial intelligence
As a result.

Being different from earlier technique natural language processing technique can only realize in the range of semantics recognition function, our times at first
The language semantic analytical technology entered is " complicated semanteme depth analysis technology ".It is mainly technically characterized by (fixed with mixed method
Property and quantitative approach) various dimensions modeling is carried out to the literal expression information of specific area, the model built up is referred to as that " multi-dimensional semantic is calculated
Method ".Such advanced algorithm model can carry out the rigorous analysis of depth to literal expression information, while text information each time
Analysis all formed a data precipitation;And as the substantial amounts of precipitation of this data is accumulated, big data and earlier set it is senior
Model algorithm carries out mutually confirmation with correcting, so that the improvement of implementation model and the modification of original character text message are improved.It is special
It is more not valuable to be, the operation of this process can light implementation model algorithm automatic evolution, or iteration upgrade-i.e.:
Realize that multi-dimensional semantic depth analysis artificial intelligence is independently evolved.And during this original character text message by automatic error-correcting with repairing
The part changed has become international academic community very forward position and commercially valuable part.Figure below is that multi-dimensional semantic is analyzed in production
Application in product design:
Word is embedded in (Word Embeddings)
Building deep learning model using neutral net can realize to single vocabulary near synonym, the database such as related term
In relation formation machine learning training pattern, so as to more accurately accomplish multidigit semantic analysis.
For example:W:Words → Rn is a parameterized function, and the word in some language is mapped to high dimension vector by it
(general 200 to 500 dimension).For example so:
" W (" cat ")=(0.2, -0.4,0.7 ...)
W (" mat ")=(0.0,0.6, -0.1 ...) "
After initialization, one random vector of each word correspondence in W.It can learn significant vector and appoint to perform
Business.
One network of training predicts whether 5 tuple (5-gram) (continuous 5 words) ' sets up ' by it.We can be with
At will select the tuple of a pile 5 (such as cat sat on the mat) and then one of word is at will changed into another word (ratio
Such as cat sat song the mat), then the 5 tuples estimation of half can all become absurd and null(NUL).
The model of training can take out the sign vector of each word in 5 tuples by W, input to another and cry R's
Module, module R can attempt to predict that this 5 tuple is ' establishment ' either ' broken '.Then it is desirable that seeing:
" R (W (" cat "), W (" sat "), W (" on "), W (" the "), W (" mat "))=1
R (W (" cat "), W (" sat "), W (" song "), W (" the "), W (" mat "))=0 "
As shown in Fig. 2 direct feel once word embedded space, we can be visualized with t-SNE to it.t-
SNE is a complicated high dimensional data visualization technique.
" map " that this word is constituted is more directly perceived for us.Similar word from closely.Another method is to see pair
For one given word, as shown in figure 3, which other word is nearest from it.We can see that these words are all again
It is much like.
After more complicated relation is encoded out, the database of multidigit semantic analysis can form relation as shown in Figure 4
Phrase.
