Step S101 inputs Chinese surgical procedure information.

Step S102 carries out natural language processing to Chinese surgical procedure information, obtains one or more titles to be encoded.

The step can be based on the characteristics of surgical procedure information, carry out the processing such as mechanical Chinese word segmentation to operation operation information, obtain To title to be encoded.It will introduce how this illustrative methods carries out nature to Chinese surgical procedure information by embodiment six below A kind of specific embodiment of Language Processing.

Step S103 based on the standard terminology library pre-established and expands terminology bank, and lookup matches with title to be encoded Standard terminology or expand term, and by the standard terminology of successful match or expand term coding, be determined as title to be encoded Coding.

In illustrative methods of the present invention, standard terminology library includes several standard terminologies and its coding, and standard terminology is international Surgical procedure title specified in classification of diseases ICD, the coding of standard terminology is corresponding hand specified in International Classification of Diseases ICD The coding of art action name.

Expand terminology bank and include several expansion terms and its coding, it is to have synonymy with standard terminology to expand term Word or the word with relation of genus and species.Wherein, can be standard terminology when expand term has synonymy with standard terminology Be commonly called as, nickname or abbreviation etc., when expand term has relation of genus and species with standard terminology, can be conceptive or apply upper packet Include standard terminology (the high rank of surgical procedure type represented relative to standard terminology) or included by standard terminology (relative to The low rank of surgical procedure type that standard terminology represents).In order to encode needs, according to clinical experience, enable and expand term and tool There is the corresponding coding of the standard terminology of synonymy or relation of genus and species unanimously.

In this illustrative methods, acceptable revised standard terminology bank in real time expands terminology bank, for example, increasing new expansion Term deletes existing expansion term, so that standard terminology library, expansion terminology bank more meet the need of ICD-9-CM-3 codings It will.

In this illustrative methods, standard terminology library and expansion terminology bank form an ontology dictionary, standard terminology and expansion art Language is the ontology in the ontology dictionary, is as shown in table 1 the part of standards term that ontology dictionary includes and expansion term and its volume Code.

Table 1

It will introduce how this illustrative methods searches the standard art to match with title to be encoded by embodiment seven below Language or a kind of specific embodiment for expanding term.

Embodiment one

As shown in figure 3, for a kind of automatic coding of specific Chinese surgical procedure information, including：

Step S201 inputs Chinese surgical procedure information.

Step S202 carries out natural language processing to Chinese surgical procedure information, obtains one or more titles to be encoded.

Step S203 based on the standard terminology library pre-established, expands terminology bank and Hypothetical classification terminology bank, searches and treat Standard terminology that encoding name matches expands term or Hypothetical classification term, and by the standard terminology of successful match, expand art The coding of language or Hypothetical classification term is determined as the coding of title to be encoded.

The present embodiment is that Hypothetical classification terminology bank is increased in illustrative methods, which includes several Hypothetical classification term and its coding.

Hypothetical classification term represents ad hoc type treatment means, and ad hoc type treatment means correspond to a variety of resection operation types, This variety of resection operation type is standard terminology.

Hypothetical classification term has one-to-one standard terminology, it is assumed that term of classifying is encoded to its corresponding standard art The coding of language.According to the regulation of ICD-9-CM-3, if the disease that the ad hoc type treatment means are directed to is the non-malignant of site of pathological change Tumour, then the corresponding standard terminology of Hypothetical classification term is the disease damage resection of site of pathological change；If the ad hoc type treatment means needle To disease for site of pathological change malignant tumour and do not need to do organ transplant, then the corresponding standard terminology of Hypothetical classification term is The total resection of site of pathological change；If the disease that the ad hoc type treatment means are directed to is the malignant tumour of site of pathological change and does not do organ Transplanting is not suitable for cutting entirely, then the corresponding standard terminology of Hypothetical classification term is the ablation of site of pathological change.

In the present embodiment, Hypothetical classification terminology bank can also be revised in real time, for example, increase new Hypothetical classification term or Existing Hypothetical classification term is deleted, so that Hypothetical classification terminology bank more meets the needs of ICD-9-CM-3 codings.

For example, table 2 show part Hypothetical classification term and its corresponding standard terminology that Hypothetical classification terminology bank includes And coding.

Table 2

Hypothetical classification term (ad hoc type treatment means)	Standard terminology	Coding
			Liver Cancer under Radical Operation	Partial hepatectomy	50.22011
Hepatic cyst resection	Hepatopathy damages resection	50.29009
			Diverticulectomy of stomach	Excision of lesion of stomach	43.42004

As shown in table 2, the disease that ad hoc type treatment means " Liver Cancer under Radical Operation " are directed to is the malignant tumour and discomfort of liver Organ transplant is done in conjunction, then corresponding standard terminology is " partial hepatectomy ".

Again as shown in table 2, the disease that ad hoc type treatment means " hepatic cyst resection " are directed to is the non-malignant tumors of liver, Then corresponding standard terminology is " hepatopathy damage resection ".

Again as shown in table 2, the disease that ad hoc type treatment means " resection of gastric carcinoma " are directed to is the malignant tumour of stomach and needs Organ transplant is done, then corresponding standard terminology is " Radical Gastrectomy ".

Embodiment two

As shown in figure 4, for a kind of automatic coding of specific Chinese surgical procedure information, including：

Step S301 inputs Chinese surgical procedure information.

Step S302 carries out natural language processing to Chinese surgical procedure information, obtains one or more titles to be encoded.

Step S303 based on the standard terminology library pre-established, expands terminology bank and odd encoder terminology bank, searches and wait to compile Standard terminology that code title matches expands term or odd encoder term, and by the standard terminology of successful match, expand term or The coding of odd encoder term is determined as the coding of title to be encoded.

The present embodiment is that odd encoder terminology bank is increased in illustrative methods, which includes several more volumes Code term and its coding.

Odd encoder term is ad hoc type surgical procedure type；The premise that ad hoc type surgical procedure type performs is another hand Art action type；Ad hoc type surgical procedure type and another surgical procedure type for standard terminology or expand term；

The coding of the coding for being encoded to ad hoc type surgical procedure type of odd encoder term and another surgical procedure type Combination.

In actual clinical, if doctor has write a surgical procedure title, the premise which performs is another A surgical procedure, then the surgical procedure title just belongs to odd encoder term.

In the present embodiment, odd encoder terminology bank can also be revised in real time, for example, increasing new odd encoder term or deleting Existing odd encoder term, so that odd encoder terminology bank more meets the needs of ICD-9-CM-3 codings.

For example, table 3 show the part odd encoder term that odd encoder terminology bank includes and its corresponding standard terminology and volume Code.

Table 3

Embodiment three

As shown in figure 5, for a kind of automatic coding of specific Chinese surgical procedure information, including：

Step S401 inputs Chinese surgical procedure information.

Step S402 carries out natural language processing to Chinese surgical procedure information, obtains one or more titles to be encoded.

Step S403 based on the merging terminology bank pre-established, treats encoding name and is pre-processed.

Merge terminology bank and include several merging terms and its coding；Wherein, merge term to provide for International Classification of Diseases ICD Can substitute at least two and meanwhile occur other standards term single standard terminology；At least two simultaneously occur other Standard terminology is the combining objects of the merging term；Merge terminology bank and further include each whole combining objects for merging term. Wherein, merge term and be different from its any one corresponding combining objects.

Clinically doctor may write multiple surgical procedure titles in a medical record, according to the rule of ICD-9-CM-3 Fixed, these surgical procedure titles can be classified as a surgical procedure title, i.e., practical above multiple surgical procedure titles are one Multiple steps of surgical procedure title.

In the present embodiment, merging terminology bank can also be revised in real time, had for example, increasing new merging term or deleting Merging term or modification combining objects so that merge terminology bank more meet ICD-9-CM-3 coding needs.

Table 4 is to merge one that terminology bank includes to merge term and its coding and whole combining objects.

Table 4

Step S403 is specially：Judge in one or more titles to be encoded, if include any one or more merging Whole combining objects of term, if comprising any one or more whole combining objects for merging term are substituted for correspondence Merging term.

Step S404 based on the standard terminology library pre-established and expands terminology bank, and lookup matches with title to be encoded Standard terminology or expand term, and by the standard terminology of successful match or expand term coding, be determined as title to be encoded Coding.

Example IV

As shown in fig. 6, for a kind of automatic coding of specific Chinese surgical procedure information, including：

Step S501 inputs Chinese surgical procedure information.

Step S502 carries out natural language processing to Chinese surgical procedure information, obtains one or more titles to be encoded.

Step S503 based on the omission terminology bank pre-established, treats encoding name and is pre-processed.

It omits terminology bank and includes several omission terms and its coding；Wherein, omitting term can as defined in ICD-9-CM-3 To substitute the single standard terminology of at least two standard terminologies occurred simultaneously；It is at least two while the mark occurred to omit term One in quasi- term；At least two standard terminologies occurred simultaneously are the omission object of the omission term；Omit terminology bank also Object is omitted altogether including each omission term；

In medical record when certain surgical procedure titles occur simultaneously, surgical procedure be other surgical procedures leading hand Art, according to the regulation of ICD-9-CM-3, some of corresponding surgical procedure titles are without coding.

In the present embodiment, omission terminology bank can also be revised in real time, had for example, increasing new omission term or deleting Omission term or modification omit object, so as to omit the needs that term Kuku more meets ICD-9-CM-3 codings.

Table 5 is to omit one that terminology bank includes to omit term and its coding and be omitted altogether object.

Table 5

Step S503 is specially：Judge in one or more titles to be encoded, if include any one or more omissions Term is omitted altogether object, if comprising any one or more objects that are omitted altogether for omitting term are substituted for correspondence Omission term.

Step S504 based on the standard terminology library pre-established and expands terminology bank, and lookup matches with title to be encoded Standard terminology or expand term, and by the standard terminology of successful match or expand term coding, be determined as title to be encoded Coding.

Embodiment five

As shown in fig. 7, for a kind of automatic coding of specific Chinese surgical procedure information, including：

Step S601 inputs Chinese surgical procedure information.

Step S602 carries out natural language processing to Chinese surgical procedure information, obtains one or more titles to be encoded.

Step S603 based on the standard terminology library pre-established and expands terminology bank, and lookup matches with title to be encoded Standard terminology or expand term, and by the standard terminology of successful match or expand term coding, be determined as title to be encoded Coding.

This, which is completed, searches the standard terminology to match with title to be encoded or expands term this process, should during have The standard terminology to match less than title to be encoded or expansion term may be searched.This is because the ontology in ontology dictionary is (no By being standard terminology or expand term) it is the relevant word of surgical procedure title, however practical Chinese surgical procedure letter Often be related to a variety of concepts of medical field, not only surgical procedure title in breath, it is also possible to be related 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 only to the coding for action name of performing the operation, therefore, if there is disease name, drug in Chinese surgical procedure information Title, medical treatment consumptive materials title etc., the present invention can select not to encode it.In addition, practical Chinese surgical procedure information is also Although it is to represent surgical procedure information that may include some, it not can determine which kind of surgical procedure title corresponded specifically to Word, such as some do not meet ICD-9-CM-3 taxonomic hierarchies, it is impossible to determine its specific corresponding surgical procedure title.Such as " attrition ", although representing surgical procedure title, its concept is too general, can not determine specifically art is worn down at what position, be face Portion's attrition, cheekbone attrition or Laser final guidance shell；For another example, " denaturation art " is specific although representing surgical procedure title It is that man becomes female urethra displacement plasty or man becomes vagina reconstruction and can not also determine.

In view of problem above, illustrative methods of the present invention also preset one without encryption description library, this is without encryption description Library includes several no encryption descriptions.These include without encryption description：It is preset to be used to represent surgical procedure information but determine The word of surgical procedure title；Preset disease name；Preset nomenclature of drug；And preset medical treatment consumptive materials title.

For example, table 6 show part that no encryption description dictionary includes without encryption description.

Table 6

Step S604, will do not determine coding title to be encoded in no encryption description library without encryption description progress Match, if successful match, perform preset processing step to represent not determining this title to be encoded of coding encodes, If it fails to match, this not determined to, the title to be encoded of coding is sent to artificial treatment platform and carries out artificial treatment.

Wherein, for not finding the standard terminology to match or the title to be encoded for expanding term, if phase can be found Matched no encryption description then illustrates that it belongs to expression surgical procedure information but can not determine the word of surgical procedure title, disease Name of disease claims, one kind in nomenclature of drug, medical treatment consumptive materials title, not encodes, and for cannot find match without coding The title to be encoded of term, illustrates that it is not belonging to the above-mentioned type, and for this kind of title to be encoded, the present embodiment sends it to people Work processing platform, by manually continuing with, concrete processing procedure, the present invention is not construed as limiting it.

Embodiment six

As shown in figure 8, nature language is carried out to Chinese surgical procedure information to be suitable for a kind of of illustrative methods of the present invention Speech is handled to obtain the specific embodiment of title to be encoded, including：

Step S71 pre-processes Chinese surgical procedure information character string, obtains pretreated Chinese surgical procedure Information character string.

The purpose of the step is that the character in Chinese surgical procedure information character string is converted into unified coded format, with Just subsequent processing.

Optionally, which can implement according to following concrete mode：To non-in Chinese surgical procedure information character string Chinese character is into row format normalized (for example, the symbol in Chinese surgical procedure information character string is all converted to half-angle lattice Formula is all converted to full-shape form, and English alphabet therein is all converted to uppercase format or lower case format)；And in deleting Non-medical term in literary surgical procedure information character string.The non-medical term dictionary that wherein non-medical term is pre-established by one There is provided, and non-medical term be the word of remarks effect, phrase or descriptive sentence (such as " opening inspection ", " benefit emergency treatment is remembered Account ", " bed expense is exceeded at one's own expense ", " being added more than one month, monthly received less than one month ", " paediatrics is added " etc.).

Based on the ontology dictionary, orientation dictionary, grade dictionary pre-established, pretreated Chinese is performed the operation by step S72 Operation information character string is cut into several first kind substrings and/or Second Type substring.

Wherein, first kind substring can directly be matched with the ontology in ontology dictionary, Second Type substring It can not directly be matched with the ontology in ontology dictionary.First kind substring and Second Type the substring tool being syncopated as There is independent semanteme, i.e., represented surgical procedure project information is not influenced by the character before or after it.

Ontology dictionary include aforesaid standards terminology bank and expand terminology bank, as shown in table 1, specifically include several ontologies and Ontology encodes correspondingly, standard terminology or expands term and is considered ontology in ontology dictionary.

It should be noted that before use has been arrived in the automatic coding of Chinese surgical procedure information provided by the invention When the Hypothetical classification terminology bank and/or odd encoder terminology bank stated, ontology dictionary should also be as consisting of assuming that classification terminology bank and/or more Encryption description library is (at this point, Hypothetical classification term and/or odd encoder term, omission term are also considered the sheet in ontology dictionary Body) so that can be with vacation when the first kind substring or Second Type substring that are syncopated as are as title to be encoded Surely classification term or odd encoder term or omission term match.

Orientation dictionary includes several directional terminologies, and directional terminology is for describing the targeted orientation of surgical procedure project Word.For example, directional terminology can be：Unilateral side, bilateral, left side, right side, both sides, side etc..

Grade dictionary includes several grade terms, and grade term is for describing the rank of surgical procedure project, type Word.For example, grade term can be：A grades, B grades, C grades, superfine etc..

The purpose of step S72 is that Chinese surgical procedure information is cut into the independent semantic substring (first kind Type substring or Second Type substring), effectively to avoid multiple characters with incidence relation being identified respectively The problem of so as to cause identification mistake.

After the first kind substring being syncopated as and Second Type substring are determined as title to be encoded, rear It is continuous when treating encoding name using the merging terminology bank in embodiment three or the omission terminology bank in example IV and being pre-processed, Since first kind substring and the corresponding ontology of Second Type substring may be expansion term, and merge in terminology bank Combining objects and the omission object that omits in terminology bank be standard terminology, therefore, need to by first kind substring and Expansion term corresponding to Second Type substring is converted to corresponding standard terminology, then recycles and merges terminology bank or province Slightly terminology bank is pre-processed.

As shown in figure 9, step S72 is specifically included：

Whether step S80 judges pretreated Chinese surgical procedure information character string comprising symbol；If include symbol Number, then perform step S81；If step S82 is not performed comprising symbol.

Step S81, by the character between every adjacent two symbols in pretreated Chinese surgical procedure information character string It is matched as a whole with the ontology in ontology dictionary；If successful match, step S811 is performed；If it fails to match, hold Row step S812.

Step S811, using the character cutting between the adjacent two symbols out as first kind substring.

Step S812, the adjacent two symbols and its between character be determined as wouldn't cutting character string, then perform step Rapid S83.

Step S81, step S811, step S812 foundations processing rule be：Alphabet between adjacent-symbol is made It is matched for entirety with ontology, ability cutting when only matching, otherwise temporarily not cutting.

Such as the cutting shown in table 7 to " cardiac output monitors, and consumes technology, ventricular puncture, implanted conduit with oxygen ", In, " cardiac output monitors, and consumes technology with oxygen ", " ventricular puncture, implanted conduit " they are the alphabet between symbol, and And the ontology to match can be found, therefore, it is split out respectively.

Table 7

Step S82, will be in pretreated Chinese surgical procedure information character string and ontology dictionary using mechanical Chinese word segmentation method Ontology matched；If all characters in pretreated Chinese surgical procedure information character string can be with ontology Match, then perform step S821；If there is the list failed with Ontology Matching in pretreated Chinese surgical procedure information character string A character or multiple continuous characters, then perform step S822.

Step S821 cuts the character in pretreated Chinese surgical procedure information character string according to the matched ontology of institute It branches away as first kind substring.

Step S822, judgement fail with the single character of Ontology Matching or multiple continuous characters whether be 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.

Step S82, step S821, step S822 foundations processing rule be：It will be pretreated using mechanical Chinese word segmentation method Character in Chinese surgical procedure information character string is matched with ontology, and only alphabet can find the sheet to match Ability cutting during body, otherwise temporarily not cutting.

Such as table 8 show the cutting to " 24 hours monitoring of blood pressure of electroencephalogram ", can be searched respectively using mechanical Chinese word segmentation method The ontology to match to " electroencephalogram " and " 24 hours monitoring of blood pressure ", therefore, is split out respectively.

Table 8

The mechanical Chinese word segmentation method that step S82 is used can be Forward Maximum Method type, reverse maximum matching type or minimum cutting Type.Specific dicing process, the present embodiment repeat no more.

Step S8221, according to fail with the single character of Ontology Matching or multiple continuous characters after the pre-treatment in Position in literary surgical procedure information character string, will fail with the single character of Ontology Matching or multiple continuous characters and its it It is preceding or can merge with the single character of Ontology Matching or multiple continuous characters cut out as the sub- word of Second Type later Symbol string, and can be with the single character of Ontology Matching or multiple continuous character cuttings out as first kind using remaining Character string.

Step S8222 integrally cuts out pretreated Chinese surgical procedure information character string as Second Type Substring.

Step S8221, the processing rule of step S8222 foundations is：Failing to the single character of Ontology Matching or more A continuous character is directional terminology or grade term, then performs cutting, and during cutting be by its with before or after it Character merging is cut out.

Such as table 9 show the cutting to " lung volume reduction surgery right lung neoplasty ", can be looked into respectively using mechanical Chinese word segmentation method Find " lung volume reduction surgery ", the ontology that " lung neoplasty " matches, " right side " therein is directional terminology, therefore, by " right side " Merge with " lung neoplasty " and cut out, " lung volume reduction surgery " is individually cut out.

Table 9

Whether step S83, judgement wouldn't include preset additional character in cutting character string；It if wouldn't cutting character string In comprising additional character, then perform step S831；If additional character wouldn't not be included in cutting character string, step is performed S833。

Step S831, search wouldn't be belonging to cutting character string character model, and the character model according to belonging to this corresponds to Segmentation rules to wouldn't cutting character string carry out cutting；Wherein, the character model library that character model is pre-established by one provides, And character model has one-to-one segmentation rules.

Step S832 matches the character cut out with the ontology in ontology dictionary, should if successful match The character cut out is determined as first kind substring, if it fails to match, the character that this cuts out is determined as Two type substrings；

Step S833, wouldn't cutting character string be determined directly as Second Type substring.

Step S83, step S831, step S832, step S833 foundations processing rule be：When wouldn't be in cutting character string During comprising preset additional character, cutting is carried out according to character model that wouldn't be belonging to cutting character string, is otherwise directly syncopated as Come；And match the character being syncopated as based on character model with ontology again, it wherein can will directly be matched with ontology Conduct first kind substring, it is impossible to directly it is matched be used as Second Type substring.

Such as preset additional character can include but is not limited to fullstop, colon, plus sige, branch, slash line etc..

Such as following partial character model and its segmentation rules in character model library：

(1) character model：XAY types, A is plus sige, colon；

Segmentation rules：XAY is cut out as a whole；

(2) character model：CDE types, and one of C, E are Chinese character, D is fullstop, branch；

Segmentation rules：Chinese character segmentation in C, E is come out；

(3) character model：STU types, and S and/or U is individual Chinese character, T is slash line；

Segmentation rules：STU is cut out as a whole.

Such as to " blood fat (P).Renal function detects (P) " cutting is carried out, it understands to belong to CDE through searching character model library Type then individually cuts out " blood fat (P) ", " renal function detects (P) ".
