As shown in Figure 6, be a kind of automatic coding of Chinese operation technique information specifically, comprise:
Step S501, inputs Chinese operation technique information.
Step S502, carries out natural language processing to Chinese operation technique information, obtains one or more title to be encoded.
Step S503, based on the omission terminology bank set up in advance, treats encoding name and carries out pre-service.
Omit terminology bank and comprise some omission terms and coding thereof; Wherein, the single standard terminology that can substitute at least two standard terminologys simultaneously occurred that term is ICD-9-CM-3 regulation is omitted; Omission term is one at least two standard terminologys simultaneously occurred; At least two standard terminologys simultaneously occurred are the omission object of this omission term; Omit terminology bank and also comprise whole omission objects that each omits term;
In medical record when some operation technique title occurs simultaneously, some operation techniques are the leading operations of other operation techniques, and according to the regulation of ICD-9-CM-3, operation technique title corresponding to some of them is without the need to coding.
In the present embodiment, revision can also omit terminology bank in real time, such as, increase new omission term, or delete existing omission term, or object be omitted in amendment, with the needs making omission term Kuku more meet ICD-9-CM-3 coding.
Table 5 omits term and coding thereof for omitting terminology bank comprise and all omits object.
Table 5
Step S503 is specially: judge in one or more title to be encoded, whether comprises whole omission objects of any one or more omission term, if comprise, then whole omission objects of any one or more omission term is replaced to corresponding omission term.
Step S504, based on the standard terminology storehouse set up in advance with expand terminology bank, searches the standard terminology that matches with title to be encoded or expands term, and by the coding of the standard terminology that the match is successful or expansion term, is defined as the coding of title to be encoded.
embodiment five
As shown in Figure 7, be a kind of automatic coding of Chinese operation technique information specifically, comprise:
Step S601, inputs Chinese operation technique information.
Step S602, carries out natural language processing to Chinese operation technique information, obtains one or more title to be encoded.
Step S603, based on the standard terminology storehouse set up in advance with expand terminology bank, searches the standard terminology that matches with title to be encoded or expands term, and by the coding of the standard terminology that the match is successful or expansion term, is defined as the coding of title to be encoded.
This completes the standard terminology searching and match with title to be encoded or expands this process of term, likely searches the standard terminology matched less than title to be encoded or expand term in this process.This is because the body (no matter being standard terminology or expansion term) in body dictionary is all words that operation technique title is relevant, but in the Chinese operation technique information of reality, often relate to the multiple concept of medical field, it is not only operation technique title, also may relate to disease name (such as " fracture of sternum Flail chest "), nomenclature of drug (such as " cetirizine "), medical treatment consumptive materials title (such as " pseudoxanthoma elasticum gum ") etc., but the present invention is just to the coding of operation action name, therefore, if there is disease name in Chinese operation technique information, nomenclature of drug, medical treatment consumptive materials title etc., the present invention can select will not encode to it.In addition, although it is represent operation technique information that actual Chinese operation technique information also may comprise some, such as, but can not determine the word specifically corresponding to which kind of operation technique title, some does not meet ICD-9-CM-3 taxonomic hierarchies, can not determine its concrete corresponding operation technique title.Such as " attrition ", although represent operation technique title, its concept is too general, cannot determine specifically art is worn down at what position, is facial attrition, cheekbone attrition or Laser final guidance shell; For another example, " sex change art " although represent operation technique title, specifically man becomes female urethra displacement plasty or man and becomes vagina reconstruction and also cannot determine.
Consider above problem, exemplifying method also presets one without encryption description storehouse, and this comprises some without encryption description without encryption description storehouse.These comprise without encryption description: preset for representing operation technique information but the word of operation technique title cannot being determined; The disease name preset; The nomenclature of drug preset; And the medical treatment consumptive materials title preset.
Such as, table 6 is depicted as the part that comprises without encryption description dictionary without encryption description.
Table 6
Step S604, by do not determine encode title to be encoded with without mating without encryption description in encryption description storehouse, if the match is successful, then perform default treatment step and this is not determined that the title to be encoded of encoding is encoded to represent, if it fails to match, then this is not determined that the title to be encoded of encoding is sent to artificial treatment platform and carries out artificial treatment.
Wherein, for not finding the standard terminology matched or the title to be encoded expanding term, match if can find without encryption description, then illustrate that it belongs to and represent operation technique information but the word that operation technique title cannot be determined, disease name, nomenclature of drug, one in medical treatment consumptive materials title, will not encode, and for not finding the title to be encoded without encryption description matched, illustrate that it does not belong to the above-mentioned type, for this kind of title to be encoded, the present embodiment sends it to artificial treatment platform, by manually continuing process, concrete processing procedure, the present invention is not construed as limiting it.
embodiment six
As shown in Figure 8, for being applicable to a kind of of exemplifying method, natural language processing being carried out to obtain the embodiment of title to be encoded to Chinese operation technique information, comprising:
Step S71, carries out pre-service to Chinese operation technique information character string, obtains pretreated Chinese operation technique information character string.
The object of this step is that the character conversion in Chinese operation technique information character string is become unified coded format, so that subsequent treatment.
Alternatively, this step can be implemented according to following concrete mode: carry out form normalized (such as to the non-Chinese character in Chinese operation technique information character string, symbol in Chinese operation technique information character string is all converted to half width form or is all converted to full-shape form, English alphabet wherein is all converted to uppercase format or lower case format); And the non-medical term deleted in Chinese operation technique information character string.Wherein non-medical term is provided by the non-medical term dictionary that sets up in advance, and non-medical term be the word of remarks effect, phrase or descriptive statement (such as " open inspection ", " mending emergency treatment book keeping operation ", " berth expense exceeds standard at one's own expense ", " added more than one month, monthly received less than one month ", " paediatrics is added " etc.).
Step S72, based on the body dictionary set up in advance, orientation dictionary, grade dictionary, is cut into some first kind substrings and/or Second Type substring by pretreated Chinese operation technique information character string.
Wherein, first kind substring directly can mate with the body in body dictionary, and Second Type substring directly can not mate with the body in body dictionary.The first kind substring be syncopated as and Second Type substring have independent semanteme, and namely represented operation technique project information does not affect by the character before or after it.
Body dictionary comprises aforesaid standards terminology bank and expands terminology bank, as shown in table 1, specifically comprises some bodies and body is encoded one to one, standard terminology or expand term and be considered body in body dictionary.
It should be noted that, when having used aforesaid Hypothetical classification terminology bank and/or odd encoder terminology bank in the automatic coding of Chinese operation technique information provided by the invention, body dictionary also should comprise Hypothetical classification terminology bank and/or odd encoder terminology bank (now, Hypothetical classification term and/or odd encoder term, omit term and be also considered body in body dictionary), as during title to be encoded to make the first kind substring that is syncopated as or Second Type substring or term can be omitted match with Hypothetical classification term or odd encoder term.
Orientation dictionary comprises some directional terminology, directional terminology be for describe operation technique project for the word in orientation.Such as, directional terminology can be: one-sided, bilateral, left side, right side, both sides, side etc.
Grade dictionary comprises some grade terms, and grade term is for describing the rank of operation technique project, the word of type.Such as, grade term can be: A level, B level, C level, superfine etc.
The object of step S72 Chinese operation technique information is cut into have independent semantic substring (first kind substring or Second Type substring), effectively to avoid being carried out respectively identifying by multiple characters with incidence relation thus causing the problem of identification error.
After the first kind substring be syncopated as and Second Type substring are defined as title to be encoded, merging terminology bank in later use embodiment three or the omission terminology bank in embodiment four treat encoding name when carrying out pre-service, because first kind substring and body corresponding to Second Type substring may be expand term, and the combining objects merged in terminology bank and the omission object omitted in terminology bank are standard terminology, therefore, expansion term corresponding to first kind substring and Second Type substring need be converted to corresponding standard terminology, and then utilize merging terminology bank or omission terminology bank to carry out pre-service.
As shown in Figure 9, step S72 specifically comprises:
Step S80, judges whether pretreated Chinese operation technique information character string comprises symbol; If comprise symbol, then perform step S81; If do not comprise symbol, then perform step S82.
Step S81, mates with the body in body dictionary as a whole by the character between adjacent two symbols every in pretreated Chinese operation technique information character string; If the match is successful, then perform step S811; If it fails to match, then perform step S812.
Step S811, using the character cutting between this adjacent two symbols out as first kind substring.
Step S812, this adjacent two symbols and between character be defined as wouldn't cutting character string, then perform step S83.
The processing rule of step S81, step S811, step S812 foundation is: mated with body as a whole by the alphabet between adjacent-symbol, just cutting when only having coupling, otherwise temporarily refuses cutting.
Such as, to the cutting of " cardiac output is monitored; consume technology with oxygen; ventricular puncture, through implantation catheter " shown in table 7, wherein, " cardiac output is monitored; consume technology with oxygen ", " ventricular puncture, through implantation catheter " are the alphabet between symbol, and can find the body matched, therefore, be split out respectively.
Table 7
Step S82, adopts mechanical Chinese word segmentation method to be mated with the body in body dictionary by pretreated Chinese operation technique information character string; If all characters in pretreated Chinese operation technique information character string all can with Ontology Matching, then perform step S821; Fail and the single character of Ontology Matching or multiple continuous print character if exist in pretreated Chinese operation technique information character string, then perform step S822.
Step S821, according to the body that mates using the character cutting in pretreated Chinese operation technique information character string out as first kind substring.
Step S822, judges whether fail with the single character of Ontology Matching or multiple continuous print character is directional terminology or grade term; If directional terminology or grade term, then perform step S8221; If not directional terminology or grade term, then perform step S8222.
The processing rule of step S82, step S821, step S822 foundation is: adopt mechanical Chinese word segmentation method to be mated with body by the character in pretreated Chinese operation technique information character string, just cutting when only having alphabet can find the body matched, otherwise temporarily refuse cutting.
Such as table 8 is depicted as the cutting to " electroencephalogram 24 hours monitoring of blood pressure ", and employing mechanical Chinese word segmentation method can find the body that " electroencephalogram " and " 24 hours monitoring of blood pressure " matches respectively, therefore, is split out respectively.
Table 8
The mechanical Chinese word segmentation method that step S82 adopts can be Forward Maximum Method type, reverse maximum matching type, or minimum cutting type.Concrete dicing process, the present embodiment repeats no more.
Step S8221, according to failing and the position in the single character of Ontology Matching or multiple continuous print character Chinese operation technique information character string after the pre-treatment, cut out failing as Second Type substring with single character or multiple continuous print character of Ontology Matching and can merging with the single character of Ontology Matching or multiple continuous print character before or after it, and can with the single character of Ontology Matching or multiple continuous print character cutting out as first kind substring using remaining.
Step S8222, cuts out pretreated Chinese operation technique information character string entirety as Second Type substring.
The processing rule of step S8221, step S8222 foundation is: if failing with the single character of Ontology Matching or multiple continuous print character is directional terminology or grade term, then perform cutting, and during cutting be by itself and its before or after character merge cut out.
Such as table 9 is depicted as the cutting to " lung volume reduction surgery right lung neoplasty ", adopt the body that mechanical Chinese word segmentation method can find " lung volume reduction surgery " respectively, " lung neoplasty " matches, " right side " is wherein directional terminology, therefore, " right side " and " lung neoplasty " are merged and cut out, " lung volume reduction surgery " cuts out separately.
