Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
At present, a retrieval model is usually used for retrieving components required by a building project from a BIM (building information modeling) building model, but most of the existing retrieval models return product-level components corresponding to product attributes and all relevant specification-level components thereof according to the product attributes of the components, so that the internal specifications of the components are difficult to filter, and the specific components meeting the user requirements cannot be judged, therefore, the existing retrieval models still need to manually distinguish the components meeting the specification requirements, the workload of users is increased, the retrieval efficiency is reduced, and the project progress is influenced.
In accordance with an embodiment of the present invention, there is provided an embodiment of a component search method, it should be noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer-executable instructions, and that while a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than here.
In this embodiment, a component searching method is provided, which can be used in electronic devices, such as a computer, a tablet computer, a palmtop computer, a mobile phone, and the like, and fig. 1 is a flowchart of the component searching method according to the embodiment of the present invention, as shown in fig. 1, the flowchart includes the following steps:
and S11, acquiring index information corresponding to the member to be searched in the BIM, wherein the index information comprises product attributes and specification attributes.
The component to be searched is a component required by a user, and the index information is used for indexing the component to be searched to a search engine, so that the search engine can return a corresponding retrieval result based on the index information. The index information comprises product attributes and specification attributes, the product attributes are type parameters of the components to be searched, namely parameters shared by the same type of components, and once the type parameters are modified, all component family individuals corresponding to the type parameters are correspondingly changed. The specification attribute is an example parameter of the component to be searched, namely a parameter which only affects the individual component and does not affect other components of the same type.
Specifically, the electronic device receives a member to be searched input by a user, may obtain a model file corresponding to the member to be searched, and analyzes the model file by the back end of the electronic device to obtain attribute information of the member to be searched. Taking a water pump as an example, the attribute information may include: water inlet pipe diameter, water outlet pipe diameter, water pump interval, water pump position, water outlet pipe height, length, width, water inlet radius, water outlet radius, water pump height, water pump length, equipment manufacturer, equipment model, installation mode, flow, lift and other parameters. The type parameters corresponding to different component models are different, and a modeling technician can specify which parameters are type parameters or instance parameters according to modeling requirements.
And the user inputs a component to be searched into the electronic equipment and triggers the electronic equipment to search. When the electronic equipment receives a component to be searched input by a user, the electronic equipment can perform word segmentation on the component to be searched, determine a word segmentation corresponding to a product attribute and a word segmentation corresponding to a specification attribute, and respectively construct index information corresponding to the product attribute and index information corresponding to the specification attribute based on word segmentation results. And indexing the component to be searched to a search engine for retrieval by generating index information.
And S12, searching candidate components corresponding to the components to be searched based on the product attributes.
The electronic equipment can perform preliminary search based on the received attribute information corresponding to the component to be searched, obtain a preliminary search result conforming to the attribute of the component to be searched, and filter the component conforming to the product attribute from the preliminary search result. Because the product attribute and the specification attribute are in a parent-child relationship, the components meeting the product attribute necessarily comprise specification-level components meeting the requirements of users, and the electronic equipment can take the components meeting the product attribute as candidate components corresponding to the components to be searched so as to further perform component retrieval.
And S13, screening the candidate components based on the specification attributes to obtain a target component list meeting the specification attributes.
After the candidate components meeting the product attributes are retrieved, the electronic device can filter the candidate components according to the specification attributes corresponding to the components to be searched to screen out a target component list meeting the specification attributes, and the target component lists in the target component list can be sorted according to the search correlation between the target components and the components to be searched, so that a user can quickly locate the target components meeting the specification requirements of the user.
In the method for constructing a search provided by this embodiment, by obtaining index information corresponding to a component to be searched in a BIM model, where the index information includes a product attribute and a specification attribute, a candidate component corresponding to the component to be searched is searched based on the product attribute in the index information, and then a target component list satisfying the specification attribute is screened from the candidate component based on the specification attribute in the index information. The method realizes automatic screening of the specification-level components, avoids manual distinguishing of the corresponding specification-level components under the product-level components, reduces the workload of users, improves the retrieval efficiency of the specification-level components, and ensures the progress of engineering.
In this embodiment, a component searching method is provided, which can be used in electronic devices, such as a computer, a tablet computer, a palmtop computer, a mobile phone, and the like, and fig. 2 is a flowchart of the component searching method according to the embodiment of the present invention, as shown in fig. 2, the flowchart includes the following steps:
and S21, acquiring index information corresponding to the member to be searched in the BIM, wherein the index information comprises product attributes and specification attributes.
Specifically, the step S21 may include the following steps:
s211, performing word segmentation on the component to be searched, and determining a target word segmentation result corresponding to the component to be searched.
The electronic equipment acquires attribute information corresponding to a member to be searched, which is input by a user, and performs word segmentation processing on the attribute information with the attribute value being a character string type, so that the member to be searched can be divided into a plurality of words, and a target word segmentation result corresponding to the member to be searched is determined.
S212, constructing an inverted index of the component to be searched based on the target word segmentation result, and obtaining index information of the component to be searched.
And according to the target word segmentation result, acquiring the attribute value corresponding to each target word segmentation, and forming an index table according to each attribute value and the address recorded by the attribute value. Instead of determining the attribute value from the record, the index table determines the address of the record from the attribute value, i.e. the index table belongs to the inverted index. And the index table generated based on the inverted index is the index information corresponding to the member to be searched.
And S22, searching candidate components corresponding to the components to be searched based on the product attributes. For a detailed description, refer to the related description of step S12 corresponding to the above embodiment, and the detailed description is omitted here.
And S23, screening the candidate components based on the specification attributes to obtain a target component list meeting the specification attributes.
Specifically, the step S23 may include the following steps:
and S231, obtaining the specification level segmentation words of the component to be searched, which correspond to the specification attributes.
The specification grade segmentation words are the segmentation words only influencing the individual component to be searched, such as the water inlet pipe diameter value and the water outlet pipe height value corresponding to the water pump component. After the electronic equipment acquires the target word segmentation result of the component to be searched, the specification-level word segmentation corresponding to the specification attribute can be extracted from the target word segmentation result. For example, if the component to be searched, which is received by the electronic device and input by the user, is a water pump with a model "a", a pipe diameter B, and a height C, the electronic device may extract the participles "pipe diameter B" and "height C" corresponding to the water pump and synonyms corresponding to the participles "pipe diameter B" and "height C" as the specification-level participles.
S232, filtering a plurality of target components containing the specification grade participles from the candidate components.
And searching the candidate building blocks according to the specification level participles, and filtering one or more target building blocks containing the specification level participles. The target participles containing the specification level participles are target components meeting the specification attributes.
S233, the display order of the plurality of target members is calculated.
After the electronic device receives the target components which are returned by the search engine and meet the specification attributes, the display sequence of the target components can be calculated, and the target components can be displayed to the user in the calculated display sequence.
Specifically, the step S233 may include the steps of:
(1) and acquiring the search relevance of the target word segmentation.
The search relevance of the target participle is the relevance between the target participle and the search word, wherein the search word is a synonym corresponding to each participle. Specifically, a synonym thesaurus, a thesaurus dictionary, a stop word thesaurus and the like can be added by means of the ElasticSearch engine, after the electronic device obtains a plurality of target segmented words corresponding to the component to be searched, the segmentation results can be optimized by means of the synonym thesaurus, the thesaurus dictionary, the stop word thesaurus and the like added by the ElasticSearch engine, operations such as synonym addition and stop word removal can be performed, for example, windows and the like are common search words, and the words can be set as synonyms. When the target word is "window", the search word may be "window", and may also be "window", i.e. these words are equivalent, and any one of the inputs may search for the relevant component. The electronic device may determine the search relevance by comparing search results returned by its search engine.
(2) Scoring each target component based on the search correlation and the feature data of the target component; the feature data comprises component version, browsing amount, downloading amount and parametrizable parameter number.
The score corresponding to each target member may be determined based on its search relevance and feature data. Specifically, the feature data includes a component version, a browsing amount, a downloading amount, and the number of parameterable parameters. The final scoring result D is the composite score + the relevance score. Wherein, the comprehensive score is the component parameterization score, the component version score, the component monthly average browsing amount score and the component monthly average downloading amount score; the building block parameterization score is 100 (1-math.pow (0.895, number of building block parameterization parameters)).
The more version support, the higher the score; the higher the monthly average download amount is, the higher the score is; the higher the monthly average browsing volume is, the higher the score is; the more the number of parametrizable parameters is, the higher the score is; the higher the search relevance, the higher the score. Relevant data may be returned by the search engine for each of the above scores to determine, for example, a score of 100 when the component version is 2014; score 99 at 2015; a score of 2016 of 98; a score of 54 at 2017; a score of 41 at 2018, etc. Of course, the final scoring result may also be a weighted sum of the scores corresponding to the search relevance and the scores corresponding to the feature data, which is not limited in the present application.
(3) And determining the display sequence corresponding to the target components based on the scoring result.
The electronic equipment sorts the obtained scoring results corresponding to the target components from high to low, and the ranking order of the scoring results from high to low is used as the display order of the target components.
S234, a plurality of target members are arranged in the display order, and a target member list is generated.
And arranging all the target components according to the determined display sequence to obtain a target component list meeting the specification attribute, and displaying the target component list to a user so that the user can quickly locate the target components required to be searched by the user.
According to the search construction method provided by the embodiment, the target word segmentation result corresponding to the component to be searched is obtained, and the inverted index of the component to be searched is constructed based on the target word segmentation result, so that the index information of the component to be searched is obtained. Index information of the member to be searched is generated based on the inverted index, and the member to be searched is retrieved through the index information, thereby increasing the search speed of the target member.
The method comprises the steps of obtaining specification grade words of a component to be searched corresponding to specification attributes, filtering candidate components based on the specification grade words, and screening out a target component list meeting the specification attributes, so that a user is prevented from manually screening the specification grade components. The display sequence of each target component in the target component list is determined based on the scoring result, and the scoring result corresponding to each target component is determined based on the component search correlation, the component version, the browsing amount, the downloading amount and the parametrizable parameter number corresponding to the target component. Therefore, the components which best meet the requirements of the user are ensured to be displayed at the forefront, and the workload of the user for searching the target components which meet the specification requirements of the user from the target component list is further reduced.
In this embodiment, a component searching method is provided, which can be used in electronic devices, such as a computer, a tablet computer, a palmtop computer, a mobile phone, and the like, and fig. 3 is a flowchart of the component searching method according to the embodiment of the present invention, as shown in fig. 3, the flowchart includes the following steps:
and S31, acquiring index information corresponding to the member to be searched in the BIM, wherein the index information comprises product attributes and specification attributes. For a detailed description, refer to the related description of step S23 corresponding to the above embodiment, and the detailed description is omitted here.
And S32, searching candidate components corresponding to the components to be searched based on the product attributes.
Specifically, the step S32 may include the following steps:
s321, obtaining a preliminary search result corresponding to the component to be searched based on a preset search rule.
The preset search rule is a general search rule, so that the component to be searched is subjected to initial search, and an initial search result containing the component to be searched is obtained.
Specifically, the step S321 may include the following steps:
(1) the search condition is generated based on a preset search rule, wherein the preset search rule is determined based on the attribute name, the value and the value type.
The electronic equipment can carry out standardized coding on the component to be searched and store the standardized coding in the database so as to carry out retrieval based on the standardized coding when receiving the component to be searched input by the user.
Specifically, the preset search rule is shown in table 1, the electronic device may obtain an attribute name, a value, and a value type of a component to be searched, which are input by a user, and generate the following search condition based on a standardized code corresponding to the attribute name, the value, and the value type:
43513301_ S _55^43111313_ S _23^4311111401_ S _22^43511717_ I _0^43511717_ D _200.0^43511717XX _ E _200| | 300. The search criteria may be filtered as follows:
single value matching is performed on the character string attribute 43513301, and the value is 55;
single value matching is performed on the character string attribute 43111313, and the value is 23;
single value matching is performed on the character string attribute 4311111401, and the value is 22;
a single value match is made to integer attribute 43511717, with a value of 0;
performing single value matching on the floating point type attribute 43511717, wherein the value is 200.0;
the enumerated attribute 43511717XX is multi-valued matched, with values of 200, 300.
TABLE 1 Preset search rules
| Type of value | Multiple value matching | Single value matching | Is greater than or equal to | Is less than or equal to | Range matching |
| Floating point type | √ | √ | √ | √ | √ |
| Shaping machine | √ | √ | √ | √ | √ |
| Character string type | × | √ | × | × | × |
| Enumerated type | √ | √ | × | × | × |
Wherein "√" represents a supported search; "X" indicates an unsupported search. For example, for floating-point type attributes, it supports multiple-value matching, single-value matching, greater-or-equal-to matching, less-or-equal-to matching, and range matching; string-type attributes only support single-value matching. Specifically, the multi-value matching can be expressed as: code _ type _ val1| | | val2, e.g., 43511717XX _ E _200| | 300. The single value match can be expressed as: code _ type _ val1, e.g., 43513301_ S _ 55. Greater than or equal to may be expressed as: code _ type _ val + "ge", e.g., 43511717_ I _23+ "ge". Less than or equal to can be expressed as: code _ type _ val + "le", e.g., 43511717_ I _23+ "le". The range match can be expressed as: code _ type _ val1-val2, e.g., 43511717_ D _ 200.0-300.0. Wherein, code is an attribute standard code; type is an attribute value type, and val, val1, and val2 are all values.
(2) Based on the search condition, the search obtains a preliminary search result corresponding to the component to be searched.
The search engine of the electronic device can retrieve the components related to the components to be searched based on the search conditions to obtain the initial search results of the components to be searched, for example, the height of the components to be searched is within a range of 100-200, and at this time, the search engine can perform range filtering on the heights of the components to query all the components with the heights of 100-200.
S322, acquiring product-level segmentation words of the component to be searched, wherein the product-level segmentation words correspond to product attributes.
The product-level segmentation is a segmentation affecting members of the family to which the member to be searched belongs, such as the model corresponding to the water pump member. After the electronic equipment acquires the target word segmentation result of the component to be searched, the specification-level word segmentation corresponding to the product attribute can be extracted from the target word segmentation result. For example, if the component to be searched, which is input by the user, is a water pump with a model a, a pipe diameter B and a height C, the electronic device may extract the word "model a" corresponding to the product attribute of the water pump and the synonym corresponding to the word "model a" as the product-level word.
