Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
The technical solution of the present invention will be described below by way of specific examples.
Referring to fig. 1, a schematic flow chart illustrating steps of a method for searching information according to an embodiment of the present invention is shown, which may specifically include the following steps:
s101, receiving a search request aiming at a hospital information system, wherein the hospital information system comprises a plurality of search nodes which are independently configured, and the search request carries a text to be searched;
it should be noted that the method can be applied to the hospital information system HIS. The HIS is a computer application system for information management and on-line operation in hospital management and medical activities, and is an information management system covering all the services and the whole process of the services of the hospital. The HIS provides collection, storage and processing of patient diagnosis and treatment information and administrative management information for each department to which the hospital belongs by using an electronic computer and communication equipment. The main aim of the method is to support the administrative management and the transaction processing business of the hospital, reduce the labor intensity of the transaction processing personnel, assist the hospital management, assist the high-level leaders in decision making and improve the working efficiency of the hospital, so that the hospital can obtain better social benefit and economic benefit with less investment.
In the embodiment of the invention, a plurality of search nodes can be independently configured in the HIS, so that medical care personnel can search diagnosis and treatment information of patients and administrative management information of hospitals through the HIS. The plurality of search nodes may be independent of the business process in the HIS.
In a particular implementation, a healthcare worker may enter text to be searched in a user interface provided by the HIS, thereby triggering a search request for the HIS.
S102, dividing the text to be searched into a plurality of search keywords;
in the embodiment of the invention, after receiving a search request submitted by a medical worker, the HIS may first divide a text to be searched carried in the search request into a plurality of search keywords.
In a specific implementation, a word segmentation technology may be adopted to divide the keywords of the text to be searched. Word segmentation can divide a Chinese character sequence into individual words or recombine continuous character sequences into word sequences according to certain specifications.
Existing word segmentation methods can be divided into three major categories: a word segmentation method based on character string matching, a word segmentation method based on understanding and a word segmentation method based on statistics.
The word segmentation method based on character string matching is also called mechanical word segmentation method, and is characterized by matching a Chinese character string to be analyzed with a vocabulary entry in a sufficiently large machine dictionary according to a certain strategy, and if a certain character string is found in the dictionary, the matching is successful (a word is identified). Common string matching methods include a forward maximum matching method, a reverse maximum matching method, a min-segmentation method, a bidirectional maximum matching method, and the like.
The word segmentation method based on understanding achieves the effect of recognizing words by enabling a computer to simulate the understanding of a sentence by a person. The basic idea is to analyze syntax and semantics while segmenting words, and to process ambiguity phenomenon by using syntax information and semantic information. It generally comprises three parts: word segmentation subsystem, syntax semantic subsystem and total control part. Under the coordination of the master control part, the word segmentation subsystem can obtain syntax and semantic information of related words, sentences and the like to judge word segmentation ambiguity, namely, the process of understanding sentences by people is simulated. This word segmentation method requires the use of a large amount of linguistic knowledge and information.
The statistical-based word segmentation method is to use a statistical machine learning model to learn the word segmentation rule (called training) on the premise of giving a large amount of segmented texts, so as to realize the segmentation of unknown texts. For example, a maximum probability word segmentation method, a maximum entropy word segmentation method, and the like.
The method for segmenting the word of the text to be searched can be selected according to actual needs, and this embodiment does not limit this.
S103, searching each search keyword by adopting the plurality of search nodes respectively to obtain a plurality of search results;
in the embodiment of the invention, each search keyword obtained after word segmentation can be searched by each search node respectively.
Since the plurality of search nodes in the embodiment are independently configured in the HIS and are not embedded in the business process of the HIS, the search of the search keywords by using each search node is beneficial to improving the search efficiency and reducing the influence on the business process in the search process.
S104, generating target search results according to the plurality of search results;
after each search node is searched by adopting the search keyword, a plurality of search results can be obtained. In the embodiment of the present invention, the target search result finally used for output may be identified from a plurality of search results, and the number of the target search results may be determined according to actual needs, which is not limited in this embodiment.
In the embodiment of the invention, aiming at a plurality of search results, the search results can be processed according to a uniform rule, and the matching degree of each search result is respectively scored. Then, according to the degree of the scores, a plurality of search results with the top scores can be selected as the target search results.
And S105, outputting the target search result.
After determining the target search result, the HIS may display the target search result in a user interface for reference by a healthcare worker.
In the embodiment of the invention, after a search request aiming at a hospital information system is received, a text to be searched carried in the search request is divided into a plurality of search keywords, and a plurality of search nodes which are independently configured are adopted to search for each search keyword respectively to obtain a plurality of search results, so that a target search result can be generated according to the plurality of search results and output. Since the plurality of search nodes in the embodiment are independently configured in the hospital information system and are not embedded in the business process of the hospital information system, the search of the search keywords by adopting each search node is beneficial to improving the search efficiency and reducing the influence on the business process in the search process.
Referring to fig. 2, a schematic flow chart illustrating steps of another information searching method according to an embodiment of the present invention is shown, which may specifically include the following steps:
s201, receiving a search request aiming at a hospital information system, wherein the hospital information system comprises a plurality of search nodes which are independently configured, and the search request carries a text to be searched;
it should be noted that the method can be applied to the hospital information system HIS.
In the embodiment of the invention, a plurality of search nodes can be independently configured in the HIS, so that medical care personnel can search diagnosis and treatment information of patients and administrative management information of hospitals through the HIS. The plurality of search nodes may be independent of the business process in the HIS.
In a particular implementation, a healthcare worker may enter text to be searched in a user interface provided by the HIS, thereby triggering a search request for the HIS.
For example, the text to be searched entered by the healthcare worker may be "liver injury".
S202, dividing the text to be searched into a plurality of search keywords;
in the embodiment of the invention, after receiving a search request submitted by a medical worker, the HIS may first divide a text to be searched carried in the search request into a plurality of search keywords by using a word segmentation technology.
For example, for a text to be searched, which is "liver damage", the plurality of search keywords obtained after word segmentation may include "liver", "damage", and "liver damage", etc.
S203, respectively sending each search keyword to a plurality of search nodes, wherein the search nodes are respectively provided with corresponding databases;
in the embodiment of the present invention, each search node may correspond to a database, and the database may be used to store data of each subsystem in the HIS.
For example, the database corresponding to the search node 1 may be a database of an electronic medical record system, the database corresponding to the search node 2 may be a database of a laboratory information system, and the like.
S204, searching each search keyword in each database respectively to obtain a plurality of search results;
after each search node receives the search keyword, the search node can search in the corresponding database.
For example, the search node 1 may search for search keywords such as "liver", "injury", and "liver injury" in a database of the electronic medical record system and obtain corresponding search results; the search node 2 may search for the search keywords such as "liver", "injury", and "liver injury" in the database of the inspection information system, and obtain a search result.
S205, sending the plurality of search results to a central node;
in the embodiment of the present invention, a central node may be further configured in the HIS, and the central node may be configured to perform subsequent processing on search results obtained by each search node. Such as matching search results, deduplication, calculating a matching score, and so forth.
S206, calculating matching scores of the plurality of search results through the central node;
in the embodiment of the present invention, the matching score calculated by the central node may be used to indicate the matching degree between each search result and the text to be searched. Generally, the higher the degree of match, the greater the probability that the search result will be the search result that the healthcare worker actually desires to obtain.
In a specific implementation, for any search result, the occurrence frequency of each search keyword may be respectively counted, and then the matching score of the search result is calculated according to the occurrence frequency of each search keyword. Generally, the match score is positively correlated with the number of occurrences of each search keyword.
For example, for a certain search result, the number of times that a search keyword such as "liver", "injury", and "liver damage" appears in the search result may be counted, and the search result may be scored according to the number of times of appearance.
S207, identifying a target search result according to the matching score;
in the embodiment of the invention, the plurality of search results can be sorted according to the matching scores, and the plurality of search results with the matching scores exceeding the preset numerical value are identified as the target search results.
And S208, outputting the target search result.
In the embodiment of the invention, the text to be searched is segmented into a plurality of search keywords and is searched in the corresponding databases by a plurality of search nodes, so that the concurrent processing capacity of the search process is improved, the access times of the search process to the public retrieval unit of the hospital information system are reduced, the search efficiency is improved, and the influence on the service flow in the search process is reduced.
It should be noted that, the sequence numbers of the steps in the foregoing embodiments do not mean the execution sequence, and the execution sequence of each process should be determined by the function and the internal logic of the process, and should not constitute any limitation on the implementation process of the embodiments of the present invention.
