[0017] The features and advantages of the present invention will be more clearly understood by referring to the accompanying drawings, which are schematic and should not be construed as limiting the present invention in any way. In the accompanying drawings: Figure 1 It is a structural diagram of the scientific and technological achievement evaluation and management system of the present invention. DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0019] Based on the problems pointed out in the background technology that the existing scientific and technological achievement evaluation is imperfect and the resource matching efficiency is low, resulting in low efficiency and quality of scientific and technological achievement transformation. The present invention provides a scientific and technological achievement evaluation and management system, which aims to improve the efficiency and quality of scientific and technological achievement transformation and promote the deep integration of science and technology and economy.

[0020] like Figure 1 As shown, the scientific and technological achievement evaluation and management system of the present invention includes: an information collection and extraction module 100, an information input module 200, an analysis conclusion output module 300, a semantic analysis and extraction module 400, a matching module 500, a screening module 600 and a solution generation module 700. The function of each module is described below: The information collection and extraction module 100 is used to collect enterprise information and extract target information from the enterprise information; An information input module 200, which is used to input the extracted target information into the scientific and technological achievement transformation evaluation service model; An analysis conclusion output module 300 is used to analyze the enterprise according to the scientific and technological achievement transformation evaluation service model and output a multi-dimensional analysis conclusion; In a preferred embodiment, the target information includes multiple indicators; the scientific and technological achievement transformation evaluation service model is: ; in, is the score calculation value of the scientific and technological achievement transformation evaluation service model. is the number of indicators, For the The weight of the indicator, For the The standardized value of the indicator is For the The actual value of the indicator, For the The expected value of an indicator, For the The tolerance of an indicator to deviate from the expected value. The calculation formula is: ,in, is the maximum value of all actual values ​​of indicators. It is the minimum value among all the actual values ​​of the indicators.

[0021] In the above, the target information includes the enterprise's technological innovation capability (such as the proportion of R&D investment, the number and quality of R&D personnel, and the number and quality of scientific and technological innovation projects), technology transformation efficiency (such as technology transformation cycle, transformation success rate and market response speed), industry influence (such as industry influence, market share and technical standard formulation capabilities), organizational management capabilities (such as organizational coordination capabilities, resource allocation capabilities and risk management capabilities), innovation cooperation capabilities, technology contract transaction volume (such as technology development contracts, technology transfer contracts, technology consulting contracts and technology service contracts), patent implementation rate, patent industrialization rate, number of scientific and technological achievements transformation, success rate of scientific and technological achievements transformation, diversity of scientific and technological achievements transformation forms, economic benefits of scientific and technological achievements (such as sales revenue and profit margin of transformed products), market competitiveness, scientific and technological achievements transformation cycle and at least two of the internationalization level of scientific and technological achievements.

[0022] Further preferably, the value is calculated according to the obtained score The range in which the enterprise is located determines the evaluation level of scientific and technological achievements transformation, for example, and Divide the entire interval into three subintervals. When the enterprise's scientific and technological achievements transformation evaluation level is A, When the enterprise's scientific and technological achievements transformation evaluation level is B, When the enterprise's technology transformation evaluation level is C, the subsequent resource library has an A-level resource set corresponding to the A level, a B-level resource set corresponding to the B level, and a C-level resource set corresponding to the C level. For different enterprise technology transformation evaluation levels, resources can only be matched from the corresponding resource sets. Of course, the technology transformation evaluation level is not limited to the above three levels, and can also be other levels. In addition, the score can be calculated for each indicator separately, that is, through the formula Calculate the score for each indicator separately , select the relevant content of some indicators with high scores (for example, greater than a set scoring threshold) as the basis for the subsequent generation of multidimensional analysis conclusions. For example, the calculated technology maturity score is 0.85, which is 85 points in percentage form, the industry influence score is 0.73, which is 73 points in percentage form, and the economic benefit score of scientific and technological achievements is 0.4, which is 40 points in percentage form. Assuming that the scoring threshold is set to 60 points, the two indicators greater than 60 points are technology maturity and industry influence, respectively, indicating that the company has great advantages in technology maturity and industry influence. Then the relevant content of these two indicators is used as the basis for generating multidimensional analysis conclusions, and thus as the basis for subsequent matching of resources to ensure that the matched resources can correspond to the company's advantageous dimensions.

[0023] Semantic analysis and extraction module 400, which is used to perform semantic analysis on the multi-dimensional analysis conclusion and extract key information; In the above, the step of "performing semantic analysis on the multidimensional analysis conclusions and extracting key information" includes: Use text segmentation and part-of-speech screening to pre-process the text of the multidimensional analysis conclusions; The preprocessed words are used as nodes, and a graph model is constructed based on the co-occurrence relationship between words; Use the iterative formula of TextRank to calculate the TextRank value of each node until convergence, where the iterative formula of TextRank is: ; in, For Node The TextRank value of the node importance score), , and are nodes in the graph model (i.e. , and represent different words in the text), is the damping coefficient (i.e., used to control the convergence speed during the iteration process, usually set to a value between 0 and 1, such as 0.85, which indicates the probability that a node passes its TextRank value to other nodes during the iteration process), Point to the node The node set (that is, the node other words that co-occur), For slave nodes The node set of departure (that is, co-occurrence and other words pointed to), For Node To Node The weight of the edge (i.e., the and The strength of the association between For Node To Node The weight of the edge (i.e., the and The strength of the association between For Node The TextRank value of the node importance score), where Used to traverse from All nodes starting from The sum of the weights of all outgoing edges; Sort the words according to the TextRank value and select the top preset number of words as keywords.

[0024] In the above, through text preprocessing, such as text segmentation and part-of-speech screening, irrelevant information and noise are effectively removed, substantive words are retained, and the co-occurrence relationship between words is used to build a graph model to capture the semantic association between words, so as to more accurately identify key information. The TextRank algorithm is used to calculate the TextRank value of each node, efficiently evaluate the importance of words, and iterative calculation is performed until convergence to ensure that the keyword extraction results are stable and reliable. The extracted keywords directly reflect the core content of the multidimensional analysis conclusion, which is convenient for quickly grasping the key points of the analysis, and at the same time enhances the interpretability and readability of the results. This method does not rely on specific domain knowledge or data formats, has wide versatility and adaptability, and can flexibly adapt to analysis conclusions of different lengths and complexities by adjusting the preprocessing rules and the parameters of the TextRank algorithm. Ultimately, the extracted key information can serve as the basis for further analysis, support deeper data mining and knowledge discovery, and also provide a concise and clear overview to help make decisions quickly. Of course, in addition to using the above method to perform semantic analysis on the multidimensional analysis conclusions and extract key information, the TF-IDF algorithm can also be used to extract keywords in the text.

[0025] A matching module 500, which is used to input the extracted key information into the resource library and perform matching using a matching model; In a preferred embodiment, the matching model is: ; in, is the matching degree calculated by the matching model. is the weight factor, For key information eigenvalues, The first eigenvalues, is the total number of features, Features and Features The correlation coefficient between Features and Features The variance between .

[0026] Specifically, all characteristic values ​​of key information can be converted into vector form. Similarly, each resource in the resource library has some attributes, which can also be converted into vector form. The matching degree can be calculated through the formula of the above matching model. .

[0028] A screening module 600 is used to screen all resources with a matching degree greater than a preset value using a matching model; The solution generation module 700 is used to generate a recommended solution for the transformation of scientific and technological achievements based on all the screened resources and enterprise information.

[0029] Preferably, the above step of "generating a recommended plan for transformation of scientific and technological achievements based on all the screened resources and enterprise information" includes: Perform text summarization and information extraction on all screened resources and enterprise information; Specifically, first input the information set, for example, the text information set of all resources is , the enterprise information text is , for each resource text and corporate information text , using a deep learning-based text summarization model (such as BERTSum) to generate summaries, where the resource summary is , the enterprise summary is , using named entity recognition (NER) and relation extraction (RE) techniques to extract key information from the summary, where the entity set is , the relationship set is .

[0030] Build a knowledge graph and perform semantic reasoning on the knowledge graph, converting the semantic reasoning into an intermediate representation; Specifically, a knowledge graph is constructed using entity and relationship sets. , perform semantic reasoning on the knowledge graph to discover potential associations and patterns (use path finding algorithms to discover indirect relationships between entities and use rule reasoning to derive new relationships), and convert the reasoning results into an intermediate representation, such as a logical expression or graph structure, to facilitate subsequent natural language generation.

[0031] An example of using the above path finding algorithm to calculate indirect relationships between entities is as follows, assuming Representing Entities and The set of paths between The formula is as follows: This formula indicates that and The path between them can be found by finding an intermediate entity , so that and Between and and There are relationships between them to build, recursively apply this formula, you can find all possible paths, the above Is a connected entity and intermediate entities relationship, Is an intermediate entity and the target entity relationship.

[0032] Fill in the preset text template based on the intermediate representation and perform text polishing; Specifically, a large number of text templates for generating recommendation solutions are preset, and specific text content is filled in according to the intermediate representation and templates. Natural language processing technology (such as grammar checking and sentence reorganization) is used to polish the generated text to improve readability and fluency.

[0033] The polished and finally generated recommendation solution is output in text form.

[0034] The present invention has the following beneficial technical effects: The scientific and technological achievement evaluation and management system provided by the present invention realizes the comprehensive collection of enterprise information, accurate extraction of target information, scientific evaluation of scientific and technological achievements, in-depth interpretation of multi-dimensional analysis conclusions, effective extraction of key information, accurate matching of resources, and intelligent generation of recommended solutions for the transformation of scientific and technological achievements by integrating multiple functional modules such as information collection and extraction, information input, analysis conclusion output, semantic analysis and extraction, matching, screening, and solution generation.
