Abstract
The present invention relates to an interactive inquiry unit for generating basic inquiry information of a subject to be inspected and for deriving basic information for the basic inquiry corresponding to the basic inquiry information; A language analyzing unit for analyzing the basic speech information and measuring a language disorder corresponding to each language ability item, and comparing the corpus information and the diagnostic evaluation information with the language disorder to determine the result of the inquiry including the disorder, Discloses a language obstacle autonomous inspection system and method for early diagnosis of a language disorder that induces utterance of a testee for each scenario by referring to a type of obstacle if the judgment is judged to be pending .
Description
More particularly, the present invention relates to a technique for discriminating the presence or absence of a language disorder, such as primary progressive aphasia and mild cognitive impairment accompanied by dementia.
A conventional neurological approach based diagnosis of dementia was performed through blood tests and brain imaging tests using MRI (Magnetic Resonance Imaging) or Positron Emission Tomography (PET).
The neuropsychological approach or the neurolinguistic approach based dementia diagnosis was performed through a neuropsychological test which indirectly grasps the cognitive function of the brain.
Among the aforementioned tests, the determinants for diagnosing dementia are physical examinations, blood tests and brain imaging tests.
Typically, dementia and accompanying language disorders are classified into Primary Progressive Aphasia (PPA) and Mild Cognitive Impairment (MCI), which can be diagnosed through the results of brain imaging or pathological features, In order to make an accurate diagnosis, it was necessary to identify the characteristics of speech disorders first and make an early diagnosis.
However, conventional diagnosis of dementia has been problematic in that it is diagnosed by brain image examination, analysis of brain waves by stimulation and analysis of the questionnaire by questionnaires, and posterior diagnosis is performed in which examination is performed.
In addition, since the conventional diagnosis of dementia is dependent on expensive equipment such as a brain imaging test or is an indirect method based on cognitive ability evaluation, it is difficult for the user to recognize the dementia due to a burden of cost or an environmental burden, There is a problem that accessibility for diagnosis is not easy and the user is difficult to inspect for himself.
The present invention overcomes a physical inspection environment, autonomously provides a testee's self-diagnosis, analyzes the basic speech information corresponding to basic query information to provide a language barrier, And methods.
The present invention provides a system and method for verbal language disability autonomous inspection for various types of disabilities, which measures language impairment based on language analysis based on language phenomena classification and language ability items.
The present invention provides an early diagnosis of dementia to a testee using a corpus information and diagnostic evaluation information, and provides a dynamic documentary scenario to a testee in case of suspected dementia or language impairment judgment, inducing a personalized speech, Provided is an autonomous language inspection system and method for providing an interactive test, not an inspection, to reduce the error of language failure judgment.
An autonomous language disability autonomous inspection system for early diagnosis of a language disorder according to the present invention includes: an interactive paper-making unit for generating basic question information of an examinee and deriving basic information about the basic question information; A language analyzing unit for analyzing the basic speech information and measuring a language disorder corresponding to each language ability item, and comparing the corpus information and the diagnostic evaluation information with the language disorder to determine the result of the inquiry including the disorder, And the interactive questionnaire section refers to the suspected disorder type if the judgment is judged to be suspended, and induces the testee's utterance for each scenario.
The language barrier autonomous examination system may further include a document terminal unit for providing basic query information to the testee and receiving the basic language information.
The interactive inquiry unit searches the presence or absence of the test history information of the examinee, generates inquiry inquiry information based on the inspection history information if the inspection history information exists, and generates basic inquiry information if the inspection history information does not exist .
The interactive paper inspection section can generate the paper query information for each scenario having the lexical diversity, time complexity, expressiveness, and topic continuity.
The language analyzing unit may include a language processing module for converting the basic speech information into text and processing the text, analyzing the text based basic speech information in a grammatical unit, and processing the parsed basic speech information; A language phenomenon classification module for classifying the basic speech information processed in the grammatical unit into a language phenomenon; and a language phenomenon classification module for classifying the basic speech information classified into the language phenomenon and the language disorder corresponding to the language ability item on the basis of the evaluation value referred to the language phenomenon classification And a language ability determination module for measuring the degree of the language.
The corpus information may include statistical processed speech processing information by filtering the language impairment analyzed by the language analyzing unit and processing the statistically processed language impairment candidate information or the result of the inquiry.
A method for operating a language barrier autonomous inspection system for early diagnosis of a language disorder according to the present invention includes the steps of searching an inspection history information of a testee in an interactive paper inspection unit, Generating basic query information if the test history information of the testee does not exist; Analyzing the basic speech information responded to by the testee in response to the test history information or the basic query information in the language analyzing unit and measuring a language disorder corresponding to each language ability item; Comparing the corpus information and the diagnostic evaluation information with the language impairment level in the corpus judgment section to judge the result of the inquiry such as the presence or absence of the disorder, the type of the disorder and the judgment pending, and, , Selecting the query type for each suspicious factor, and searching the scenario for each query type to generate the inquiry query information.
The present invention enables automatic diagnosis by the testee through the self terminal of the language barrier autonomous inspection system or the medical terminal such as the desktop and the smart phone, and enables the early diagnosis of dementia having no intervention of any other person, .
According to the present invention, it is possible to analyze an utterance classified by a wide range of disabilities necessary for diagnosis of a suspected language disorder from a testee through a language analyzer in real time, thereby measuring or collecting accurate and accurate diagnostic data.
The present invention can provide a diagnosis of dementia to a testee using corpus information and diagnosis evaluation information or diagnosis record information of a testee so that it is possible to identify and diagnose a wide range of language disorder types and to update diagnosis record information of a testee can do.
The present invention can provide a dynamic documentary scenario to a testee through an interactive paper-testing unit in the case of suspected dementia or language impairment, thereby providing an interactive test rather than a one-way one-way test, .
