In C4, when W≧1000, L=1+S / W; when W<1000, L=(W+S) / 1000; if the number of words W of the content related to the achievement is too small and the achievement information is incomplete, the understanding of the achievement will not be in place, and the conversion will be difficult. For example, if a scientific and technological achievement has only 20 words and the residence time is slightly longer than a few seconds, their scores will be very high if the existing calculation method is used, which will not be consistent with the actual situation. Therefore, the formula of step C4 can avoid this problem.

[0030] Preferably: in the C5, if the same day, 0.1 day or 0.6 day are all 1, and 1.3 day or 1.8 day are all 2, the priority is, R is the maturity score, I is the innovation score, A is the advancement score, V is the market value score, K is the evaluation type coefficient, L is the visitor preference, N is the number of views, and T is the registration time. The reason why the score R of maturity, the score I of innovation, the score A of advancement and the score V of market value are all added with 1 is to avoid the situation that the result is 0 when one of them is equal to 0. When screening the results, the formula can make the scientific and technological achievements evaluated by the third party be recommended first (because the third-party evaluation is more objective and fair), followed by the evaluation of invited experts, and finally the self-evaluation. The user will receive the question "Do you need intelligent recommendation information?". If you check "Yes", the scientific and technological achievements screened from the highest to the lowest priority P will be pushed to the customer, and new scientific and technological achievements that meet the conditions will be uploaded every day in the form of links or through the app. In the recommendation method of classification and grading of scientific and technological achievements, the corresponding scientific and technological achievements are first screened out through the classification content after classification and the lower and upper limit intervals of the grading content in the classification and grading of scientific and technological achievements, and then the scientific and technological achievements are sorted according to the priority after calculating their priority, so that users can see the scientific and technological achievements that best meet their needs at the first time, thereby improving the accuracy of scientific and technological achievement recommendations.

[0044] In this embodiment, a method for recommending scientific and technological achievements is provided, including: S201, constructing a scientific and technological achievement triplet based on scientific and technological achievement information. In some embodiments, the scientific and technological achievement information includes descriptive information of the scientific and technological achievements and supply-side supplementary information and other information. Based on the descriptive information of the scientific and technological achievements, analysis and processing are performed to obtain a first attribute and a first attribute value corresponding to the scientific and technological achievements; constructing a scientific and technological achievement attribute triplet based on the scientific and technological achievements, the first attribute corresponding to the scientific and technological achievements, and the first attribute value.

The description information of the scientific and technological achievement can be processed by content segmentation, and the text and pictures extracted by content segmentation are used as the attribute values ​​of the scientific and technological achievement. For example, the description information of the scientific and technological achievement "a water-to-hydrogen technology" includes: the material description and process description used for water-to-hydrogen; using the existing Ji eBa and other word segmentation technologies are used to extract keywords from the material description and process description to obtain the first attribute and the first attribute value corresponding to the scientific and technological achievement "a water-to-hydrogen technology", the first attribute is "description", and the first attribute value is the keyword obtained after keyword extraction from the material description and process description; the scientific and technological achievement attribute triple constructed according to the scientific and technological achievement, the first attribute and the first attribute value is the [achievement, description, keyword] triple, if there are pictures in the material description and the process description, the picture representation model such as the ResNet50 model is used to process the picture to obtain the picture vector of the picture; the first attribute corresponding to the scientific and technological achievement "a water-to-hydrogen technology" is "picture", and the first attribute value is the picture vector; the scientific and technological achievement attribute triple constructed according to the scientific and technological achievement, the first attribute and the first attribute value is the [achievement, picture, picture vector] triple, the supply-side supplementary information of the scientific and technological achievement includes: information on the owner of the scientific and technological achievement and information on the technical team, etc.; the supply-side supplementary information of the scientific and technological achievement is subjected to content segmentation processing, and the text and pictures extracted after content segmentation processing are used as the supplementary attribute values ​​of the scientific and technological achievement.For example, the supply-side supplementary information of the scientific and technological achievement "a water-to-hydrogen technology" includes: the introduction text of Professor Wang's team at a certain University A, other achievement materials, etc., and the existing word segmentation technologies such as Jieba are used to extract keywords from the introduction text of Professor Wang's team at a certain University A, other achievement materials, etc., to obtain the supplementary attributes and supplementary attribute values ​​corresponding to the scientific and technological achievement "a water-to-hydrogen technology". The supplementary attribute is "supplementary information", and the supplementary attribute value is the keyword obtained after the introduction text of Professor Wang's team at a certain University A, other achievement materials, etc. are extracted; the scientific and technological achievement supplementary triple constructed according to the scientific and technological achievement, supplementary attribute and supplementary attribute value is the [achievement, supplementary information, keyword] triple. The obtained scientific and technological achievement attribute triple and scientific and technological achievement supplementary attribute triple of the scientific and technological achievement "a water-to-hydrogen technology" are merged to generate the scientific and technological achievement triple of the scientific and technological achievement "a water-to-hydrogen technology". The scientific and technological achievement triple is [achievement, attribute, attribute value], and the attributes include: description, picture, supplementary information, etc.; the attribute value corresponds to the description, picture, supplementary information, etc., including keywords, picture vectors, etc. The same scientific and technological achievement has only one node in the demand and achievement knowledge graph, S202, constructing an enterprise demand triple according to the enterprise demand information. In some embodiments, the enterprise demand information includes: descriptive information and supplementary descriptive information of the enterprise demand and other information; analyzing and processing is performed based on the descriptive information of the enterprise demand to obtain the second attribute and the second attribute value corresponding to the enterprise demand; constructing an enterprise demand attribute triple according to the enterprise demand and the second attribute and the second attribute value corresponding to the enterprise demand; analyzing and processing is performed based on the supplementary descriptive information of the enterprise demand to obtain the supplementary attribute and the supplementary attribute value corresponding to the enterprise demand; constructing an enterprise demand supplementary attribute triple according to the enterprise demand and the supplementary attribute and the supplementary attribute value corresponding to the enterprise demand; generating an enterprise demand triple based on the enterprise demand attribute triple and the enterprise demand supplementary attribute triple, and performing content segmentation processing on the descriptive information of the enterprise demand, and using the text and pictures extracted after content segmentation processing as the attribute values ​​of the enterprise demand respectively.For example, the description information of enterprise demand is "a low-cost production technology of hydrogen is needed for hydrogen energy vehicles". The description information of enterprise demand is extracted with keywords using word segmentation technologies such as Ji eBa to obtain the first attribute and the second attribute value corresponding to the description information of enterprise demand. The second attribute is "description", and the second attribute value is the keyword obtained after keyword extraction from the description information of enterprise demand. The enterprise demand attribute triple constructed according to the enterprise demand, the second attribute and the second attribute value is the [demand, description, keyword] triple. If there is a picture in the description information of enterprise demand, the picture representation model such as the ResNet50 model is used to process the picture to obtain the picture vector of the picture. The second attribute corresponding to the description information of enterprise demand is "picture", and the second attribute value is the picture vector. The enterprise demand attribute triple constructed according to the enterprise demand, the second attribute and the second attribute value is the [demand, picture, picture vector] triple. The supplementary description information of enterprise demand includes: introduction to main products, introduction to the enterprise, introduction materials of the enterprise's research and development achievements, etc. The supplementary description information of enterprise demand is processed with content segmentation, and the text and pictures extracted after content segmentation are respectively used as the supplementary attribute values ​​of enterprise demand. Use JieBa and other word segmentation technologies to extract keywords from the main product introduction, company introduction, and company research and development results introduction materials to obtain supplementary attributes and supplementary attribute values ​​related to the company's needs. The supplementary attribute is "supplementary information", and the supplementary attribute value is the keyword obtained by extracting keywords from the main product introduction, company introduction, and company research and development results introduction materials; the company demand supplementary triple constructed according to the company's needs, supplementary attributes, and supplementary attribute values ​​is the [demand, supplementary information, keyword] triple, and the company demand attribute triple and the company demand supplementary attribute triple obtained are merged to generate the company demand triple. The company demand triple is [demand, attribute, attribute value], and the attributes include: description, picture, supplementary information, etc.; the attribute values ​​correspond to the description, picture, supplementary information, etc., including keywords, picture vectors, etc. The same enterprise demand has only one node in the demand and achievement knowledge graph; S203, determine the matching coefficient between the attribute value of the scientific and technological achievement attribute triplet and the attribute value of the enterprise demand triplet. In some embodiments, multiple methods can be used to obtain the matching coefficient between the attribute value of the scientific and technological achievement attribute triplet and the enterprise demand triplet.For example, use a variety of existing methods to obtain the attribute values ​​of the scientific and technological achievement attribute triples and the word vectors of the enterprise demand triples; based on the existing multiple distance algorithms, calculate the cosine similarity between the attribute values ​​of the scientific and technological achievement attribute triples and the word vectors of the enterprise demand triples, and use the cosine similarity as the matching coefficient; S204, based on the matching coefficient, as well as the scientific and technological achievement attribute triples and the enterprise demand triples, construct a demand and achievement knowledge graph. In some embodiments, the same attribute values ​​of the scientific and technological achievement attribute triples and the enterprise demand triples are merged. If the matching coefficient between the attribute value of the scientific and technological achievement attribute triples and the attribute value of the enterprise demand triples is greater than the matching coefficient threshold, then the matching coefficient between the attribute value of the scientific and technological achievement attribute triples and the attribute value of the enterprise demand triples is marked;.

The classified content is deemed to have no restriction conditions. When the lower limit of the score is not set, the restriction condition of the lower limit of the score of the classified content is deemed to be the minimum value. When the upper limit of the score is not set, the restriction condition of the upper limit of the score of the classified content is deemed to be the maximum value. In one embodiment, when the classification label formed by the classification content of a certain graded score or classification category of the scientific and technological achievements uploaded by the user received by the system in the scientific and technological achievements grading and classification method is not clear, when searching for scientific and technological achievements in the scientific and technological achievements retrieval method, the lower limit and upper limit interval of the graded content or the classified content is checked, then the scientific and technological achievements are deemed to not meet the screening requirements and will not appear in the corresponding list of scientific and technological achievements found in step B2; when searching for scientific and technological achievements in the scientific and technological achievements retrieval method, the lower limit and upper limit interval of the graded content or the classified content is not checked or unchecked, then the scientific and technological achievements are deemed to meet the screening requirements.

[0049] It is worth noting that the last set filtering parameters (check or uncheck the categories to be filtered in step B1, and the lower and upper rating limits set in step B3) will be used as the default filtering conditions for the next search of the results. All filtering parameters can be adjusted manually.

[0050] The basic research category in the achievement type is checked, and the software in the achievement form is unchecked. At this time, the system will find all scientific and technological achievements of all industries, the achievement type is the basic research category, the achievement form is not software, all the regions where the completion teams are located, the nature of the units where the completion teams are located, all the proposed transformation methods and all the registration times, and then set the upper limit of the innovation score to 10 points, the lower limit of the innovation score to 9 points, the upper limit of the economic value score to 9 points, the lower limit of the economic value score to 7 points, the upper limit of the market valuation score to 10 points, and the lower limit of the market valuation score to 5 points. On the basis of step B2, scientific and technological achievements that simultaneously meet the requirements of innovation between 9 and 10 points, all advanced scores, all maturity scores, economic values ​​between 7 and 9 points, market valuations between 5 and 10 points, all social value corresponding scores, all risk levels and all intellectual property scores can be screened out; in the retrieval method for classifying and grading scientific and technological achievements, by using the classification content after the grading and classification of scientific and technological achievements and the lower and upper limit intervals of the grading content, the scientific and technological achievements required by the user can be accurately retrieved;

[0051] A method for recommending scientific and technological achievements, using a scientific and technological achievement data set formed by the scientific and technological achievement classification and grading method; comprising the following steps: C1: setting screening parameters: checking or unchecking the classification content to be screened for each classification category, and setting a lower limit and an upper limit for each grading content; C2: extracting the maturity score R, the innovation score I, the advancement score A and the market value score V of the scientific and technological achievements; C3: setting the evaluation type coefficient K, when there is only self-evaluation, K=1, when there is only invited expert evaluation, K=2, when there is a third-party evaluation, K=3; when there is a third-party evaluation, the third-party evaluation result is given priority; when there is no third-party evaluation and there is an invited expert evaluation, the expert evaluation result is given priority; when there is no third-party evaluation and invited expert evaluation, the self-evaluation result is given priority; when there is no self-evaluation result, the indicator is determined to be unsatisfactory, that is, it is not recommended; C4: setting the visitor's preference L, the average time S for users to browse scientific and technological achievements and the number of words W of the content related to the achievement;

[0052] When W≧1000, L=1+S / W; when W<1000, L=(W+S) / 1000; if the word count W of the content related to the achievement is too small, the achievement information is incomplete, the understanding of the achievement is not in place, and the conversion is difficult. For example, if a scientific and technological achievement has only 20 words and the stay time is slightly longer than a few seconds, the score will be very high if the existing calculation method is used, which will not match the actual situation. Therefore, the formula of step C4 can avoid this problem; C5: Set the number of views N; N is obtained according to the number of user views; C6: Set the registration time of the scientific and technological achievement from the current time The duration is the registration time T; the unit of T is day, take the smallest integer larger than the actual time value (i.e. round up), such as the same day, 0.1 day or 0.6 day are all 1; 1.3 day or 1.8 day are both 2, C7: calculate the priority P of scientific and technological achievements that simultaneously meet the screening parameters of step C1, and then recommend them in descending order according to the size of the priority P; the priority wherein R is the maturity score, I is the innovation score, A is the advancement score, V is the market value score, K is the evaluation type coefficient, L is the visitor preference, N is the number of views, and T is the registration time. The reason why the score R of maturity, the score I of innovation, the score A of advancement and the score V of market value are all added with 1 is to avoid the situation that the result is 0 when one of them is equal to 0. When screening the results, the formula can make the scientific and technological achievements evaluated by the third party be recommended first (because the third-party evaluation is more objective and fair), followed by the evaluation of invited experts, and finally the self-evaluation. The user will receive the question "Do you need intelligent recommendation information?". If you check "Yes", the scientific and technological achievements screened from the highest to the lowest priority P will be pushed to the customer, and new scientific and technological achievements that meet the conditions will be uploaded every day in the form of links or through the app. In the recommendation method of classification and grading of scientific and technological achievements, the corresponding scientific and technological achievements are first screened out through the classification content after classification and the lower and upper limit intervals of the grading content in the classification and grading of scientific and technological achievements, and then the scientific and technological achievements are sorted according to the priority after calculating their priority, so that users can see the scientific and technological achievements that best meet their needs at the first time, thereby improving the accuracy of scientific and technological achievement recommendations.

[0053] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
