Fig. 1 is a flowchart summarizing a method for displaying a chemical safety technical specification knowledge graph for professional search according to an embodiment of the present application, where on the basis of the first embodiment, this embodiment relates to a method for displaying a chemical safety technical specification knowledge graph for professional search at a user terminal, and it should be understood that if a user triggers an opening operation of a general search interface, steps S101A, S102A, S103 and step S104A are executed; and if the user triggers the opening operation of the professional search interface, executing the steps S101B, S102B, S103 and S104B. As the safety experts understand the safety technical specifications of various chemicals deeply and pay more attention to the incidence relation among the chemicals, the method also provides a knowledge map professional search interface of the safety technical specifications of the chemicals, the search interface provides a condition search bar, and forms a query requirement by the selection of a composition mode selection box and a search category selection box in each condition search bar and the input of a search content input box, and then sends the query requirement to the server; after receiving the retrieval result returned by the server, displaying the chapter content required to be checked by the user according to the retrieval result, and the method can reveal the association relationship among various chemical safety technical specifications and solve the problem that the user cannot obtain the association relationship among the chemical safety technical specifications.

The method for searching and displaying the knowledge graph speciality of the chemical safety technical specification specifically comprises the following steps:

and S101B, responding to the opening operation of the professional search interface, and displaying a knowledge graph professional search interface of the chemical safety technical specification.

In the embodiment of the application, the displayed knowledge graph professional search interface of the chemical safety technical specification comprises a condition retrieval bar; the condition search field includes: a composition mode selection box, a retrieval type selection box, a retrieval content input box and a condition retrieval bar increase and decrease control.

Specifically, clicking the composition mode selection box displays AND OR. Clicking on the search category selection box may display the following: the name of the hazardous chemical substance, the chapter mark of each chapter and the section mark of each chapter. The retrieval content input box may input therein content to be retrieved. Illustratively, if the retrieval category selected by the retrieval category selection box is a dangerous chemical name, a certain chemical identifier to be retrieved can be input in the retrieval content input box; if the search category selected by the search category selection box is a chapter identifier, the contents of the chemical safety specification to be searched under the chapter can be input in the search content input box. For example, if the search category selected by the search category selection box is "individual protection", the search content input box may input "complete work, shower, and change clothes".

It should be understood that the specialized search interface can not only display individual chemical safety specifications but also correlations between chemical safety specifications.

And step S102B, acquiring the retrieval type selected by the user in the retrieval type selection frame of the condition retrieval bar and the content to be inquired input in the retrieval content input frame, and forming a query requirement by the selected retrieval type and the content to be inquired and sending the query requirement to the server.

Specifically, the contents in the retrieval category selection box and the retrieval content input box in each condition retrieval column form corresponding retrieval requirements, and then the retrieval requirements form query requirements; the query request is sent to the server.

And step S103, receiving a search result returned by the server.

Specifically, after the user terminal sends the formed query requirement to the server, the server retrieves the pre-constructed chemical safety technical specification knowledge graph according to the query requirement, and returns the retrieval result to the user terminal.

And S104B, displaying the contents meeting the query requirements in the knowledge graph of the chemical safety technical specification in a graph or table mode according to the retrieval result.

It should be understood that the contents of the chemical safety technical specifications satisfying the query requirements or the association relationship between the chemical safety technical specifications may be displayed according to the search results.

Specifically, if the retrieval category selected by the retrieval category selection frame is a certain chapter identifier and the content to be queried is not input, displaying the content of the chapter in all the chemical safety technical specifications in the chemical safety technical specification knowledge graph; if the retrieval category selected by the retrieval category selection box is a certain chapter mark and the content to be queried is input, displaying corresponding sections of all chemical safety technical specifications in the chapter of the chemical safety technical specifications knowledge graph, wherein the corresponding sections comprise the content to be queried; and if the retrieval type selected by the retrieval type selection frame is the name of the dangerous chemical, displaying the content in the chemical safety technical specification corresponding to the input chemical identification.

Because some users, such as safety experts, need to not only refer to the contents of a single chemical safety technical specification, but also analyze the association relationship between chemical safety technical specifications; therefore, through the retrieval type selection frame and the retrieval content input frame in the condition retrieval column, a user can select to retrieve a chemical safety technical specification corresponding to a certain chemical or retrieve the association relation between the chemical safety technical specifications; if the selection of the retrieval category selection box is a dangerous chemical name and the input of the retrieval content input box is a certain chemical identification, displaying a chemical safety technical specification corresponding to the chemical identification; and if the selection of the retrieval category selection box is a certain chapter mark, and the input of the retrieval content input box is the content in the chapter, displaying the association relationship of all the chemical safety technical specifications in the chemical safety technical specification knowledge graph in the chapter, namely displaying the subsection content of the content, including the input content in the chapter, of all the chemical safety technical specifications in the chapter.

The method provided by the embodiment of the application responds to the opening operation of the professional search interface, and displays the knowledge map professional search interface of the chemical safety technical specification; the chemical safety technical specification knowledge graph professional search interface comprises a condition retrieval bar; the condition search field includes: a retrieval category selection box and a retrieval content input box; acquiring a retrieval type selected by a user in a retrieval type selection frame of a condition retrieval bar and contents to be inquired input in a retrieval content input frame, and forming a query requirement by the selected retrieval type and the contents to be inquired and sending the query requirement to a server; receiving a retrieval result returned by the server; and displaying the contents meeting the query requirements in the knowledge graph of the chemical safety technical specification in a graph or table mode according to the retrieval result. Therefore, through the selection and the input of the category selection box and the retrieval content input box in the condition retrieval column, the individual display and the common display of the knowledge map of the chemical safety technical specification can be realized, and the requirement of a safety expert on analyzing the association relationship between the chemical safety technical specifications is met.

Optionally, the chemical safety technical specification professional search interface may further include a conditional retrieval bar addition control, and after the chemical safety technical specification professional search interface is displayed in step S101B, the conditional retrieval bar displayed in the chemical safety technical specification knowledge base professional search interface may be added in response to a trigger operation for adding the control to the conditional retrieval bar. The condition search column for increasing display comprises: the composition mode selection box of the search condition appears in the 2 nd and later condition search fields.

In the embodiment of the application, the knowledge-graph professional search interface of the chemical safety technical specification can further comprise a conditional retrieval bar reduction control. For example, after the displayed condition search bar is added as shown in fig. 8, a condition search bar reduction control may be provided on the right side of the condition search bar. After the displayed condition search bar is added, the display method of the chemical safety technical specification further comprises the following steps: and responding to the triggering operation of the conditional retrieval bar reducing control, and reducing the conditional retrieval bar displayed in the professional search interface of the chemical safety technical specification. The "+" button in fig. 8 is a conditional search bar addition control, and the "-" button is a conditional search bar reduction control, and as shown in fig. 8, a conditional search bar addition control may be provided on the right side of the first conditional search bar. When more than one conditional search field is present, a composition mode selection box appears. As shown in fig. 8, a conditional search bar reduction control is provided on the right side of the second conditional search bar.

In the embodiment of the application, one conditional search column corresponds to one search requirement. The search requirement comprises a search category selected by a user in a search category selection box in the corresponding condition search column and the content to be inquired input in a search content input box.

Optionally, in this embodiment of the present application, a composition manner in the multiple conditional search fields may be defined as an and relationship.

According to the method provided by the embodiment of the application, by adding and reducing the condition search columns, the search requirements can be increased or reduced, the content which needs to be searched by a user can be locked more accurately, for example, the association relation of a plurality of chemical safety technical specifications in a plurality of chapters can be directly searched, the relation of the plurality of chemical safety technical specifications in the plurality of chapters is determined without searching and comparing for many times, and the efficiency of obtaining information by the user can be improved.

Optionally, if the additionally displayed condition search field includes a composition mode selection frame of the search condition, and the composition mode is the search condition corresponding to the condition search field or the search condition corresponding to the condition search field, then the step S102B obtains the search category selected by the user in the search category selection frame of the condition search field and the content to be queried input in the search content input frame, which includes:

and acquiring the composition mode selected by the user in the composition mode selection box, the retrieval type selected in the retrieval type selection box and the content to be queried input in the retrieval content input box.

In the embodiment of the application, the contents in the retrieval type selection box and the retrieval content input box in each condition retrieval column form corresponding retrieval requirements, and then the retrieval requirements form query requirements according to the selected composition mode; and sends the query request to the server.

Specifically, after the input and the selection of a user are obtained, a retrieval category selection frame and the content of a retrieval content input frame included in each condition retrieval column form a retrieval condition, a composition mode is determined through the selection of a composition mode selection frame which begins to exist in a second condition retrieval column, and the retrieval conditions form a query requirement according to the composition mode; the query request is sent to the server.

Here, the search condition in the AND-condition search field may be represented as "AND", OR the search condition in the condition search field may be represented as "OR".

In the embodiment of the application, if the contents of multiple chapters are to be searched, multiple condition search fields can be additionally displayed, multiple chapter marks are selected from the multiple condition search fields, and the corresponding composition mode is selected to be "OR" in the composition mode selection frame, so that the contents of the multiple chapters can be displayed, and the contents of 16 chapters can be displayed in the limit condition. If the contents of a section below a certain chapter are searched, a condition search field can be added, 3 condition search fields are displayed, and the condition search fields are respectively selected from the 3 condition search fields: the name of a hazardous chemical; AND, a chapter mark; AND, some section identification.

On the basis that the additionally displayed condition retrieval bar comprises a composition mode selection frame, wherein the composition mode is the retrieval condition or the retrieval condition, and step S104B shows the content meeting the query requirement in the knowledge graph of the chemical safety technical specification in the form of a graph or a table according to the retrieval result, the method comprises the following steps:

and step S104B1, if the retrieval types of the plurality of condition retrieval columns are chapter marks and the corresponding composition modes are all same, displaying the association relation of the chemical safety technical specifications meeting the query requirement in the knowledge graph of the chemical safety technical specifications on the chapters only in a table form.

And step S104B2, if the retrieval types of the plurality of condition retrieval fields are chapter marks and at least one corresponding composition mode is or, or the retrieval types of the plurality of condition retrieval fields are not chapter marks, displaying the association relationship between the chemical safety technical specifications meeting the query requirement in the chemical safety technical specification knowledge graph in a table form or a graph form.

Since the knowledge graph can only search the OR relation of two chapters, but can not search the AND relation of the two chapters, if the search categories of a plurality of condition search columns are chapter marks AND the corresponding composition modes are all corresponding to the search conditions, the association relation of the chemical safety technical specifications meeting the query requirements in the knowledge graph of the chemical safety technical specifications on the chapters is displayed in a table form. It should be understood that a query result may be presented in a table form if it can be presented in a graph form, but may not necessarily be presented in a graph form if it can be presented in a table form.

Optionally, if there are multiple search categories of the conditional search query field as chapter identifiers and corresponding composition manners are all the same, the user cannot select to display the query result in the form of a graph.

Illustratively, the case where the retrieval categories of the plurality of conditional retrieval fields are section identifiers AND the corresponding composition manners are all "AND" which is a retrieval condition, includes at least the following:

(1) The user selects the following three condition search fields: the name of a hazardous chemical; AND, a chapter mark; AND, a chapter identification. If the content of the chapter corresponding to each chapter mark of the chemical safety technical specification corresponding to the input chemical mark contains the corresponding content to be inquired, the result displayed by the table can be obtained. In the technical specification of the chemical safety corresponding to toluene, the sections of 'complete work, bathing and changing clothes' and 'emergency measures' in the section of 'individual protection' include 'for example, breathing difficulty and oxygen delivery', so that as shown in fig. 9, after the query control is clicked, a table corresponding to the query requirement can be displayed.

(2) The selections of the plurality of conditional retrieval fields are AND AND a certain chapter mark, namely, the joint query of the plurality of chapter ANs. And if no content exists in the retrieval content input box, not displaying the query result. If the retrieval content input box has content, the server queries all chemical safety technical specifications of the content to be queried on chapters corresponding to the chapter identifications in the knowledge graph, and the user terminal displays retrieval results in a form. Fig. 10 shows the association relationship between the chemical safety specifications in the chapter "emergency treatment" and "individual protection", and specifically shows the contents of the chemical safety specifications in the chapter "individual protection" including "work done, bathing and changing clothes" and "emergency treatment" including "respiratory distress, oxygen supply".

(3) The user selects the following four condition search fields: the name of a hazardous chemical; AND, a chapter mark; AND, a chapter mark; OR, name of dangerous chemical. And if the content of the chapter corresponding to each chapter mark of the plurality of chemical safety technical specifications in the OR relationship contains the content to be inquired which is input by each chapter mark, obtaining a result displayed by the table. Fig. 11 shows the case where the chemical safety technical specification corresponding to toluene and the chemical safety technical specification corresponding to chloroacetic acid both include the contents in the corresponding input boxes in the chapters "emergency measures" and "individual protection", and is also the correlation between the "toluene knowledge map" and the "chloroacetic acid knowledge map" in the chapters "emergency measures" and "individual protection".

Illustratively, the case where there are a plurality of search categories of the conditional search listing as section identifiers and at least one corresponding component is either a search condition, i.e., "OR", OR there are no search categories of the conditional search listing as section identifiers includes at least the following cases:

the user selects the following four condition search fields: the name of a hazardous chemical substance; AND, a chapter mark; OR, hazardous chemical name; OR, a certain chapter mark, and the content to be retrieved corresponding to the chapter mark is empty. At this time, the association relationship between the two dangerous chemicals and the corresponding chapters of the two headlines is inquired. As shown in fig. 12, the association relationship between the "toluene knowledge map" and the "chloroacetic acid knowledge map" in the two sections of "individual protection" or "emergency treatment" can be displayed in the form of a map.

It should be understood that if the selections of the multiple conditional search fields are all AND, bar identifiers, there is no search result. This is because it is necessary that all chemical safety specifications in the knowledge map are identical in the contents of the corresponding section.

The method in the embodiment is applied to a chemical safety technical specification knowledge graph display device, and the chemical safety technical specification knowledge graph display device can be located in a server. The server may be, among other things, a digital computer that represents various forms. Such as a desktop computer, a workstation, a server, a blade server, a mainframe computer, and other suitable computers. It should be understood that any knowledge-graph search engine is included in the server.

As shown in fig. 13, the method comprises the following specific steps:

step S201, receiving an inquiry requirement sent by a user terminal. The query requirement may include content to be queried.

Specifically, after a user inputs content to be queried and selects chapter marks in a common search interface of a knowledge graph of a chemical safety technical specification provided by a user terminal, the user terminal forms a query requirement by the content to be queried and the selected chapter marks and sends the query requirement to a server; the method comprises the following steps that a user selects a composition mode selection frame and a retrieval type selection frame of each condition retrieval column of a chemical safety technical specification knowledge graph professional search interface provided by a user terminal and retrieves content input by a content input frame, the user terminal combines the selection of the retrieval type selection frame and the content input by the retrieval content input frame into a retrieval condition, and the retrieval condition of each retrieval column is combined into a retrieval requirement and sent to a server in a composition mode;

after receiving the query request sent by the user terminal, the server executes step S202 to retrieve the chemical safety technical specification knowledge graph and returns the retrieval result to the user terminal; and after receiving the retrieval result, the user terminal displays the received retrieval result.

It should be understood that the query requirement may also include the search condition and the composition of the search condition. The retrieval conditions comprise the selection of a retrieval category selection box and the content to be queried input by a retrieval content input box.

And S202, retrieving the content meeting the query requirement in the pre-constructed chemical safety technical specification knowledge graph according to the query requirement, and returning the retrieval result to the user terminal.

If the query requirement comprises query content and the selected chapter mark, the retrieval result comprises the corresponding content of the chapter mark selected in the chemical safety technical specification corresponding to the content to be queried; the content to be inquired is a chemical identification; the content to be inquired is input by a user in a dangerous chemical search box in a common search interface; the selected chapter mark is selected in a search bar in a common search interface by a user; if the query requirement is that the user terminal is composed of the retrieval types selected by each condition retrieval column of the professional search interface and the content to be queried through the composition mode selected by the composition mode selection frame, the retrieval result meets the retrieval types, the content to be queried and the composition modes of each condition retrieval column.

Exemplarily, if the user terminal displays a knowledge graph common user search interface of the chemical safety technical specification, a query requirement which is sent by the user terminal and consists of the content to be queried and the selected chapter mark and section mark can be received; and retrieving the content meeting the query requirement in the chemical safety technical specification knowledge graph constructed in advance according to the query requirement, and returning the corresponding content comprising the chapter mark and the subsection mark selected from the chemical safety technical specification corresponding to the content to be queried to the user terminal.

Exemplarily, if the user terminal displays a professional search interface of a knowledge graph of a chemical safety technical specification, a query requirement which is sent by the user terminal and consists of a retrieval category selected by each condition retrieval column and a composition mode selected by a composition mode selection frame of contents to be queried can be received; and searching the content meeting the query requirement in a pre-constructed chemical safety technical specification knowledge graph according to the query requirement, and returning the search result meeting the search category, the content to be queried and the composition mode of each condition search column to the user terminal.

In the embodiment of the application, the pre-constructed knowledge graph of the chemical safety technical specification comprises a plurality of knowledge graphs of the chemical safety technical specification. Examples provided in this application employ a pre-constructed chemical safety specification knowledge graph as a fused knowledge graph. Specifically, a chemical safety technical specification knowledge graph constructed in advance by a knowledge graph fusion technology can be adopted.

In the embodiment of the application, the chemical safety technical specification which meets the query requirement in the chemical safety technical specification knowledge graph constructed in advance can be retrieved, and the retrieval result is returned to the user terminal.

Optionally, a display form selected by the user and sent by the user terminal may also be obtained, and if the display form is a table, the queried knowledge graph is converted into the table and returned to the user terminal.

Optionally, if the user terminal displays a knowledge graph common user search interface of the chemical safety technical specification, the user terminal can also receive a query requirement which is sent by the user terminal and consists of the content to be queried and the selected chapter identification and/or section identification; and retrieving the pre-constructed chemical safety technical specification knowledge graph by adopting a knowledge graph retrieval technology, and returning a retrieval result to the user terminal.

Optionally, if the user terminal displays a common search interface of the chemical safety technical specification knowledge graph, and the server does not receive the selected chapter mark and/or the selected bar mark, the knowledge graph corresponding to the chemical mark in the chemical safety technical specification knowledge graph constructed in advance is retrieved according to the query requirement by using a knowledge graph retrieval technology, and the retrieval result is returned to the user terminal.

Optionally, if the user terminal displays a chemical safety technical specification knowledge graph professional search interface, and there are multiple retrieval categories as chapter identifiers and at least one corresponding composition manner is or in the received query requirement, or there are no retrieval categories of multiple conditional retrieval columns as chapter identifiers, step S202 retrieves, according to the query requirement, contents meeting the query requirement in a chemical safety technical specification knowledge graph constructed in advance, and returns a retrieval result to the user terminal, which specifically includes:

searching the content meeting the query requirement in a pre-constructed chemical safety technical specification knowledge graph by adopting a knowledge graph searching technology; and returning contents meeting the query requirement in the knowledge graph of the chemical safety technical specification of the user terminal in a form of a table or a graph.

Optionally, if the user terminal displays a professional search interface of a chemical safety technical specification knowledge graph, and multiple retrieval categories exist in the received query requirement as chapter identifiers and corresponding composition manners are all the same, step S202 retrieves, according to the query requirement, content meeting the query requirement in a chemical safety technical specification knowledge graph constructed in advance, and returns a retrieval result to the user terminal, which specifically includes:

For example, if a chemical safety technical specification is searched for content to be queried which satisfies a given relationship between two chapters, that is, two chapters included in the chemical safety technical specification on two chapters simultaneously, the knowledge graph search technology cannot handle such a relationship.

Illustratively, a specific implementation manner for obtaining the initial table is as follows: if the received query request has the retrieval types of the plurality of condition retrieval columns as the chapter names and the corresponding composition modes are all same, changing the composition mode corresponding to the retrieval condition with the retrieval type as the chapter name into the composition mode; then, the knowledge map retrieval technology is adopted to retrieve the contents meeting or retrieving the requirements and process the contents into an initial table, then the database query technology is adopted to process the contents, and the final result is returned to the user terminal in the form of a table.

The method provided by the embodiment of the application receives the query requirement sent by the user terminal; the query requirement comprises query content and a selected chapter mark; the content to be inquired is a chemical identification; the content to be inquired is input by a user in a dangerous chemical search box in a chemical safety technical specification knowledge graph common search interface; the selected chapter mark is selected by a user in a search bar in a common search interface of a knowledge graph of a chemical safety technical specification; retrieving the contents of the chemical safety technical specifications meeting the query requirements in the pre-constructed chemical safety technical specifications knowledge graph by adopting a knowledge graph retrieval technology according to the query requirements, and returning the retrieval result to the user terminal; the retrieval result comprises corresponding contents of chapter marks selected from the chemical safety technical specification corresponding to the contents to be queried. The chapter contents which the user needs to check are retrieved by obtaining the selection of the user in the search bar, and the retrieval result is returned to the user terminal, so that the user can randomly check any chapter of any chemical safety technical specification, namely one chapter, multiple chapters or all chapters, and the chapter contents which the user pays attention to can be presented to relevant personnel for inquiring and using, such as production enterprises, sales enterprises, transportation enterprises, academic institutions, supervision institutions, safety evaluation and the like.
