Some suggestions on improving the quality of novelty retrieval through the power of attorney for sci-tech projects

Novelty retrieval consultation of scientific research projects is an important part of scientific and technological management, which is highly policy-oriented, scientific and technical. It is of great significance to improve the scientificity and standardization of scientific and technological management and decision-making, reduce low-level repetition of scientific research projects and inaccurate evaluation of scientific and technological achievements, and improve the efficiency of scientific and technological investment. The power of attorney for novelty retrieval of scientific and technological projects is an important basis for novelty retrieval. The power of attorney for novelty retrieval of scientific and technological projects (hereinafter referred to as power of attorney) is the main description of scientific and technological projects entrusted by project researchers and an important basis for retrieval personnel to carry out novelty retrieval. In the power of attorney, the novelty retrieval personnel are most concerned about the main technical content of the project, the purpose and requirements of retrieval and the quality of filling in Chinese and English keywords. Therefore, the project entrusting unit should invite the technical personnel of the project as far as possible when entrusting the project. Technicians are familiar with the key points and technological innovations of the project, and proper keyword selection is very helpful for novelty retrieval personnel to locate accurately in information retrieval. On the basis of fully understanding the content of the subject or project, the novelty retrieval personnel decompose the required novelty retrieval content according to the novelty retrieval requirements of the core and technical points of the subject or project research put forward by the client and the novelty retrieval regulations of the superior science and technology management department, browse the retrieved documents with high correlation, analyze the scope, distribution and correlation of the documents against the novelty retrieval points, determine the closely related documents, and compare and analyze the closely related documents with the novelty retrieval points, and finally get pertinence. The influence of the power of attorney for novelty retrieval of scientific and technological projects on the quality of novelty retrieval: Lancaster, an American intelligence expert, analyzed 3200 retrieval problems in the evaluation and analysis of the system. Among 797 retrieval failures, 279 were caused by retrieval strategies, accounting for 35% of all retrieval failures; Among 3038 errors, 983 errors were caused by retrieval strategies, accounting for 32% of all errors. Therefore, whether the retrieval strategy is correct or not directly affects the retrieval effect. However, the formulation of retrieval strategy should be based on the novelty search points and Chinese and English keywords provided in the Novelty Search Power of Attorney. Power of attorney is an important document for novelty retrieval personnel. Therefore, if the information provided by the client is inaccurate or vague, it will directly restrict the quality of novelty retrieval. I. Influence of Accuracy of Novelty Retrieval Point on Novelty Retrieval Quality Novelty Retrieval Point is a brief description of the research contents, research methods, technical routes and innovation points of the main technical indicators of Novelty Retrieval Project, which is summarized and refined by novelty retrieval personnel based on the relevant information provided by the client in the Novelty Retrieval Power of Attorney, through communication with the client, and on the basis of in-depth research and reading of the subject application and achievement declaration. The key to novelty retrieval is accuracy, not the more the better. Improper extraction of novelty retrieval points often leads to the deviation of novelty retrieval users in selecting retrieval words and formulating retrieval strategies, which directly affects the reliability and pertinence of novelty retrieval conclusions. For example, a project studies the preparation of 2,5-dimethylpyrazine, and the novelty provided by customers is to prepare 2,5-dimethylpyrazine with high yield and high purity by using new catalysts and fixed bed reactors. Through the communication with customers, we know that the catalyst used by the research group is zinc, copper, chromium and aluminum. After preliminary search, it was found that the preparation of 2,5-dimethylpyrazine from isopropanolamine or ZnO, aluminosilicate zeolite, platinum-palladium alloy, nickel-cobalt alloy, iron, copper chromite and zinc chromite as catalysts has been reported in foreign literature. However, there is no literature at home and abroad about the simultaneous use of raw materials and catalysts in our research group. Therefore, the novelty of refining lies in the preparation of 2,5-dimethylpyrazine with isopropanolamine as raw material and Zn-Cu-Cr-Al as catalyst. The preparation method of chemical substances in this project has been refined through this scheme, but the vague terms such as high yield and high purity provided by the research group can not be reflected in the novelty retrieval point. Another example is "Research and Development of EQ6 102Ni Engine with Electronic Control Injection of CNG for Large Passenger Cars". By studying the technical data and technical performance index data provided by customers, we find that although the engine provided by customers is characterized by: (1) single fuel compressed natural gas; (2) Open-loop control of electronically controlled injection, maximum air-fuel ratio and minimum air-fuel ratio; (3) electrically controlled high-energy sequential ignition; (4) supercharging and intercooling; (5) shallow basin combustion chamber, fuel system with low vortex, high efficiency, low pollution and strong turbulence entering the air passage; (6)EQ6 102Ni electronically controlled CNG injection engine, reaching mass production level, used for large passenger cars; (7) The post-treatment of tail gas adopts an oxidation catalytic conversion port; (8) Develop an electronic control simulation device, which is also suitable for the development and calibration of electronic control systems of other CNG engines. However, after trial test, many technologies are common technologies adopted by engines. When dealing with this kind of topic, we must get rid of some features that are not particularly novel and leave the most essential features. After a lot of searching and analysis, the novelty of this topic is "single fuel lean-burn natural gas engine", and the novelty of this topic is engine, and the attributive of this engine can be decomposed into three items: "single fuel", "lean-burn" and "natural gas". In retrieval, we should firmly grasp these three items in order to make a comparative analysis in literature analysis. If any item is omitted, the novelty retrieval of this topic is incomplete, and the conclusion of this topic is inaccurate, objective and unfair in the novelty retrieval conclusion part. Similarly, if we add any item to the novelty search according to the original description of the client, it will be redundant to the subject and may eventually cause huge losses to the users. Another example is the project "High Resistance Target in Magnetron Sputtering of High Stability Thin Film Resistors". Customers need to know that the components of high resistance target in magnetron sputtering are nickel, chromium and silicon. The research group gives the temperature coefficient of resistance of the target, and carries out temperature resistance test, life test and high temperature storage test, and gives the specific data. The client thinks that no one else has done these experiments, which is what the research group thinks is novel. After searching, it is found that there are studies on temperature resistance test, life test and high temperature storage test at home and abroad, but the data are different from this topic. Therefore, the novelty and advancement of this project are mainly reflected in various indicators and parameters. If "high stability", "thin film resistance" and "magnetron sputtering" are literally attributes of "medium and high resistance target", we will think that the novelty of this project lies in the preparation process. Therefore, after discussion and negotiation, the novelty retrieval point is: "study the high resistance metal film resistor in sputtering of Ni, Cr and Si targets and optimize various indexes". In practical work, we often encounter novelty retrieval topics similar to these situations, whose novelty is only to make some small improvements on the basis of other people's existing research, such as adopting a new method, new technology, partial improvement or a collection of methods. For this kind of novelty retrieval problem, we should focus on reflecting the key technical indicators of novelty when refining the main points of novelty retrieval, which will be the basis for literature retrieval and comparative analysis. If some words with vague semantics are used as novelty retrieval points, the retrieval scope will be expanded and the quality of novelty retrieval will be reduced. Although in this case, we successfully completed the novelty retrieval task through contact and discussion with the client, it is undeniable that this prolonged the novelty retrieval time, disrupted the client's declaration plan and reduced our work efficiency. Secondly, the accuracy of keywords affects the quality of novelty retrieval. In the process of retrieval, the retrieval words and/or symbols (including subject words, sub-subject words, keywords, classification number, patent number, chemical substance registration number, etc.) must be correctly selected. ), accurately match the logic, correctly formulate the retrieval type and retrieval strategy, and try to check the retrieval strategy; At the same time, we should constantly adjust the retrieval strategy, in addition to the logical combination between retrieval words, we should also consider the possible combination between retrieval types and retrieval words and between retrieval types. Only by expanding and limiting the continuous alternation of retrieval can we detect documents with high correlation or close correlation. In the power of attorney, it is very important for novelty retrieval personnel to fill in Chinese and English keywords during the retrieval process. Using different search terms, the retrieval results are different. Therefore, how to choose keywords is more important. For the entrusting party, the following points should be noted. (The figure below mostly shows the number of documents detected from VIP library) 1. Pay attention to the loanwords Boltzmann 55 Euclid 30 1 Boltzmann 15 Euclid 207 Boltzmann 2 17 Euclid 5 Niels Boltzmann 12 Euclid 3 Boltzmann 2 Euclid Geometry 655. 2. The practice of careful use of phrases or phrases in novelty retrieval shows that many English keyword groups in novelty retrieval contracts are pieced together by the entrusting party, such as: title: optimization of dump parameters and dump scheme in open pit mine ① optimization of mining and drainage integration ② zoning &; Periodic dumping 0.3 ecological adaptation index 0.4 automatic dumping design 0.5 multi-objective optimization multi-objective programming 845 (The above is the word frequency of English phrase test from Google search engine provided by the entrusting party, only 5 see a few results. After novelty retrieval, the English phrase "multi-objective optimization" was changed to "multi-objective optimization", and the word frequency suddenly rose to 289,000! ) 3. Avoid using self-made text search terms, which should cover common technical terms familiar in the industry. Self-made words of the entrusting party, product names and product models named by enterprises themselves shall not be used as search terms. The accuracy of the power of attorney will indeed have a great impact on the quality of novelty retrieval, but it is not only the responsibility of the client to improve the quality of the power of attorney, but also the novelty retrieval personnel will always pay attention to the seriousness and authority of novelty retrieval, so that the client can understand the technical requirements of filling in the power of attorney from all aspects and guide the user to fill in the power of attorney as much as possible to ensure the continuous improvement of novelty retrieval in practice.
