[0051] Figure 1 The present invention provides a schematic diagram of the overall process of a project bidding matching method.

[0052] Figure 2 This is a schematic diagram of the overall structure of a project bidding matching system provided by the present invention. DETAILED DESCRIPTION

[0053] like Figure 1-2 As shown, the present invention provides a project bid matching method and system, including a project bid matching method and a project bid matching system based on the project bid matching method. The system and method are matched and based on the same inventive concept. The system and method are introduced separately below.

[0054] A project bid matching method includes the following steps:

[0055] Step 1: Obtain bidding project information in various regions, extract project types based on the bidding project information, and screen out suitable projects based on the previous projects of the bidding company;

[0056] Step 2: Extract the bidding content of the project to be tendered to obtain the bidding requirements of the project to be tendered and the evaluation criteria corresponding to the bidding requirements;

[0057] Step 3: Obtain the previous project experience of the company to be bid, and obtain the project indicators and corresponding indicator index of the company to be bid based on the project experience;

[0058] Step 4: Match the bidding requirements and corresponding evaluation criteria of the project to be tendered with the project indicators and corresponding indicator indexes of the company to be tendered to determine the chance of winning the bid.

[0059] The present invention automatically obtains the bidding project information of various regions, analyzes the bidding project information, obtains its bidding requirements and corresponding evaluation standards, evaluates the bidding companies based on previous projects, obtains project indicators and corresponding indicator indexes, uses the previous project experience to numerically represent the strength of the bidding companies, and then compares the two based on the numerical values, automatically completes the bidding matching, and ensures the chance of winning the bid.

[0060] Below, we introduce each step in detail.

[0061] In step 1, the bidding project information of each region is obtained, and the project type is extracted based on the bidding project information. The appropriate bidding projects are screened out in combination with the previous projects of the bidding companies.

[0062] Among them, to obtain the bidding project information of various regions, you can enter multiple bidding websites and the system will regularly access to obtain the bidding project information. You can also use a web crawler program to automatically obtain the bidding project information on the Internet. The bidding project information obtained may be more than one, but multiple. After the bidding project information is released, proceed to the subsequent work.

[0063] The step of extracting the project type based on the bidding project information includes:

[0064] Converting the bidding project information into text format;

[0065] Extracting the bidding project name from the bidding project information;

[0066] Decomposing the bidding project name into words using a stop word list;

[0067] According to the part of speech and position of each word, the project type in the bidding project information is obtained.

[0068] The present invention converts the bidding project information into a text format, and obtains the project type by processing the text format. The project type is the construction object of the project, including road construction, tunnel construction, bridge construction and other project types. Among them, the bidding project names are, for example: 1. Urban road and bridge engineering 2. Water supply engineering and pipe network transformation 3. Drainage engineering and pipe network transformation 4. Power supply facility engineering and power grid transformation, etc. The stop word list can adopt the "Harbin Institute of Technology Stop Word List", disconnect each word, and then according to the magnetism of the word, this can be obtained from a word database, such as a dictionary. After obtaining, the part of speech of the word is extracted, and combined with the position where the word appears, generally at the head or tail of the bidding project name, the project type in the bidding project information can be obtained. With this basis, the following work can be carried out.

[0069] The project type is extracted based on the bidding project information, and suitable projects to be bid are screened out based on the previous projects of the bidding company, including:

[0070] Based on the project type in the bidding project information, select projects of the same type from the previous projects of the bidding company;

[0071] When the number of screened projects is not less than the set number of projects, output the projects to be tendered corresponding to the tender project information;

[0072] When the number of screened projects is less than the set number of projects, the projects to be tendered corresponding to the tender project information are deleted.

[0073] After obtaining the project type in the bidding project information, the present invention can match it with the bidding company's previous projects. For example, if the project type in the bidding project information is to build a hydropower station, the bidding company's previous projects for building a hydropower station can be found, that is, projects that are consistent with the project type. Since the company has experience in multiple projects, the chance of winning the bid after bidding is greater. The number of projects set in the present invention is generally 3, which can be modified according to actual conditions and can also be set to 1 or 2.

[0074] In step 2, the bidding content of the project to be tendered is extracted to obtain the bidding requirements of the project to be tendered and the evaluation criteria corresponding to the bidding requirements. This is to extract the text of the bidding content of the project to be tendered, specifically, by the following methods:

[0075] Convert the bidding content of the project to be tendered into text format;

[0076] Split the bidding requirements in the bidding content of the project to be bid according to the set keywords to obtain paragraphs of each bidding requirement;

[0077] Decompose the paragraph of the bidding requirement using a stop word list to obtain individual words;

[0078] According to the part of speech and position of each word, combined with the bidding requirement database, the evaluation criteria corresponding to the bidding requirement are obtained;

[0079] The bidding requirement database (which is pre-established) is used to store various evaluation indicators of the bidding requirements and the words corresponding to each evaluation indicator.

[0080] The present invention also processes the content of the bidding content by text processing, wherein the keywords are pre-set, and the keywords are the names of the bidding requirements and their synonyms. When the keywords are detected, they are split, so that the paragraphs of the various bidding requirements can be obtained, such as construction experience, construction efficiency, engineering quality, etc. For the evaluation criteria corresponding to the bidding requirements, we adopt a quantitative approach, evaluate the evaluation criteria according to the industry standards of construction, and express the evaluation criteria in the form of numerical ranges. For example, the construction period of a hydropower station is generally 2 years. If the evaluation criteria are required to be 3 years (greater than 2 years), then the numerical range of the evaluation criteria is defined as 2-3 years. If the evaluation criteria are required to be 2 years (equal to 2 years), then the numerical range of the evaluation criteria is defined as 2 years. If the evaluation criteria are required to be 1.8 years (less than 2 years), then the numerical range of the evaluation criteria is defined as 1.8-2 years. This concept needs to be used when comparing in the future. At this point, what we need to do is to make the evaluation criteria corresponding to the bidding requirements correspond.

[0081] The evaluation criteria corresponding to the bidding requirements are obtained based on the part of speech and position of each word in combination with the bidding requirements database, including:

[0082] According to the words corresponding to the evaluation indicators in the bidding requirements database, filter out the words in the paragraphs of the bidding requirements that are the same as the words corresponding to the evaluation indicators;

[0083] According to the positions of the identical words, the sentences containing the identical words are selected;

[0084] According to the part of speech of each word in the sentence where the same word is located, the evaluation criteria corresponding to the bidding requirements are obtained.

[0085] The present invention provides the source of the evaluation criteria. Generally, the evaluation criteria corresponding to the bidding requirements can be known based on the coherence of the sentences. Generally, there will be a numerical value after the bidding requirements as the evaluation criteria.

[0086] In step 3, the previous project experience of the company to be bid is obtained, and the project indicators and corresponding indicator indexes of the company to be bid are obtained based on the project experience, including:

[0087] Obtain the completion status of previous projects of the bidding company, each of the previous projects corresponds to a completion status, and each complete status constitutes the project experience;

[0088] Extracting a project completion report from the completion status and converting the project completion report into a text format;

[0089] Extracting project indicators and corresponding indicator indexes corresponding to the completion status from the project completion report;

[0090] The project indicators and corresponding indicator indexes corresponding to the various completion conditions are combined to obtain the project indicators and corresponding indicator indexes of the company to be bid.

[0091] In the present invention, step 3 is an analysis of the bidding company's situation. Projects completed outside the bidding company are analyzed through analysis reports to determine project indicators and indexes. Generally, project indicators are the aforementioned indicator requirements, and indexes determine whether they fall within the assessment criteria. These indicators are expressed numerically, as detailed later. This step is used to map the project indicators and indexes of the bidding company. Text processing is still used, but for multiple projects, each project will have a project completion report. To demonstrate the bidding company's overall strength, data is extracted from multiple projects, and the project indicators and indexes corresponding to each completion status are merged to obtain the project indicators and indexes of the bidding company. This merging process first obtains the project indicators and indexes per unit area for each project. Then, the project indicators and indexes per unit area for each project are selected and merged. The indexes that meet the criteria (this criterion is calculated as a percentage, and the top 50% of the data can be used) can be selected. The merging method can be to remove the median or mode, or to calculate the average.

[0092] In step 4, the bidding requirements and corresponding evaluation criteria of the project to be tendered are matched with the project indicators and corresponding indicator indices of the bidding company to determine the winning probability of the bid, including the following methods:

[0093] Comparing the bidding requirements of the project to be tendered and the project indicators of the company to be tendered with a synonym comparison method to obtain the degree of similarity between the two;

[0094] Screening out the bidding requirements and project indicators whose degree of similarity exceeds a set value;

[0095] Comparing the selected bidding requirements and corresponding evaluation criteria with the selected project indicators and corresponding indicator indices to obtain a comparison result;

[0096] The probability of winning the bid is determined based on the result of the comparison.

[0097] Based on the data obtained above, this step of the present invention compares and processes the data, wherein the synonym comparison method is to query the synonyms of the bidding requirements and project indicators in the dictionary respectively, and then query the synonyms of the synonyms of the bidding requirements and project indicators. If after three rounds of query, if the synonyms of the two are one word, it is determined that the degree of synonymy between the two is low. If after two rounds of query, if the synonyms of the two are one word, it is determined that the degree of synonymy between the two is average. If after one round of query or no query, if the synonyms of the two are one word, it is determined that the degree of synonymy between the two is high, and these degrees are assigned values. The value of high degree of synonymy is 90%, the value of average degree of synonymy is 80%, and the value of low degree of synonymy is 50%. The set value in this step is 60%. After having this basis, we compare them. As mentioned above, the evaluation standard is a range value, and the index is a numerical value. Therefore, by comparing the index with the evaluation standard, we can determine whether it is within the range. If it is within the range, the chance of winning the bid is very high. If not, the chance of winning the bid will be reduced. The following is the process of comparing and obtaining the comparison results, that is, comparing the selected bidding requirements and corresponding evaluation standards with the selected project indicators and corresponding indexes, and obtaining the comparison results, including:

[0098] Determining whether the index is within the range of the evaluation criteria based on the selected bidding requirements and corresponding evaluation criteria, and the selected project indicators and corresponding indicator indices;

[0099] When the indicator index is within the range of the evaluation standard, the comparison result is within the evaluation range;

[0100] When the indicator index is not within the range of the evaluation standard, the comparison result is not within the evaluation range, and a deviation value of the indicator index from the evaluation standard is given.

[0101] In the present invention, there are two comparison results: one is within the scope of the evaluation criteria, and the other is not within the scope of the evaluation criteria. For the case of being within the scope of the evaluation criteria, it means that the actual situation of the bidding company meets the requirements of the tender and the winning bid is high. For the case of not being within the scope of the evaluation criteria, it means that the actual situation of the bidding company is somewhat different from the requirements of the tender. The difference between the two values is the deviation value from the range, which is the deviation value of the index index from the evaluation criteria, which is the discount ratio for the winning bid probability. Generally, the deviation value of the index index from the evaluation criteria is inversely proportional to the discount ratio for the winning bid probability. The larger the deviation value, the smaller the discount ratio. This ratio is pre-set according to the bidding requirements and corresponds one-to-one with the deviation value. The discount ratio is combined with the winning bid probability through multiplication. Of course, in actual work, each bidding requirement needs to be weighted to obtain the final winning bid probability. The setting of the weight is also pre-set according to the needs of the bidding and the actual situation of the industry.

[0102] Based on the above-mentioned project bid matching method, the present invention proposes a project bid matching system, which is used as an execution unit to execute the project bid matching method. The method and system are based on the same inventive concept. The project bid matching system includes:

[0103] The module for acquiring projects to be tendered is used to obtain information on tendered projects in various regions, extract project types based on the information, and screen out suitable projects to be tendered based on the previous projects of the companies to be tendered.

[0106] The bidding matching module is used to match the bidding requirements and corresponding evaluation criteria of the project to be bid, with the project indicators and corresponding indicator indexes of the company to be bid, to determine the winning probability of the bid.

[0107] The above modules coordinate with each other and perform their respective tasks to complete various steps of a project bidding matching method.

[0108] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way.
