Description

Technical Field

[0001] The present invention specifically relates to a quantitative measurement and calculation method for interdisciplinary degree. Background Art

[0002] With the development of disciplines, single-discipline research is prone to ceiling effects, prompting scholars to turn their attention to other disciplines, thereby drawing on useful ideas, theories and methods to find breakthroughs in scientific research. Modern academic research shows the characteristics of collectivism and interdisciplinary synergy, the diversification of research subjects and organizational diversity. As the country implements the innovation-driven development strategy, interdisciplinarity has become an inevitable trend in academic innovation.

[0003] Scholars are the main body of academic research. On the one hand, interdisciplinarity places higher demands on the scholars' own knowledge structure and scientific research capabilities. On the other hand, in the research process, they need to integrate the thinking, methods and knowledge of different fields and disciplines, and cooperate and communicate with researchers from other disciplines. Therefore, studying the degree of interdisciplinarity of scholars will help us understand the current interdisciplinarity status of Chinese academic research, the role of interdisciplinary scientific research in talent cultivation, and the correlation between high-level academic output and interdisciplinarity.

BRIEF DESCRIPTION OF THE DRAWINGS

[0141] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative labor.

[0142] Figure 1 It is a schematic diagram of a quantitative measurement calculation method of interdisciplinary degree of the present invention. DETAILED DESCRIPTION

[0143] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0144] like Figure 1 The present invention shows a quantitative measurement and calculation method for interdisciplinary degree, comprising: S1: determining multiple evaluation index items. S2: obtaining data of evaluation index items corresponding to the scholars to be evaluated. S3: calculating the interdisciplinary degree index scores of multiple evaluation index items through the obtained data of evaluation index items. S4: calculating the interdisciplinary degree value of the scholars to be evaluated based on the interdisciplinary degree index scores of multiple evaluation index items. The above steps are described in detail below.

[0145] For step S1: determine multiple evaluation index items.

[0146] This application analyzes the degree of interdisciplinary of scholars, mainly based on Stirling's three-dimensional measure index of interdisciplinarity: diversity (the number of disciplines), balance (the degree of evenness of discipline distribution), and difference (the degree of difference in discipline nature). Among the three-dimensional measure indexes, diversity provides motivation for scholars' academic research, the difference between disciplines provides innovation elements for scholars, and balance makes academic research tend to be stable.

[0147] In the implementation manner of this application, the specific method for determining multiple index items is as follows:

[0148] Preliminarily screen multiple candidate index items.

[0149] Calculate multiple candidate index items through a quantitative correlation analysis method.

[0150] Select the candidate indexes with higher correlation as evaluation index items according to the calculation results.

[0151] Specifically, the specific method for determining multiple evaluation index items is as follows:

[0152] Select C scholars, and relevant personnel related to the scholars (such as students and colleagues) score their degree of interdisciplinarity. The scoring range is from 0 to 1, and the average score is taken as the survey score g of the scholars' degree of interdisciplinarity. i .

[0153] Determine that there are a total of T candidate index items, 0 ≤ t < T. By collecting data and statistically calculating the values of the candidate index items, the candidate index data of C scholars are obtained:

[0154] (x i1 ,x i2 ,x it …x iT )0 ≤ i < C

[0155] Among them, x it is the value of the t-th index of the i-th scholar.

[0156] For each candidate index item, calculate its correlation with the survey score of the scholars' degree of interdisciplinarity in order to select the most relevant index item as the final index item. The specific calculation formula is as follows:

[0157]

[0158] Among them, cov(X t ,g) represents the covariance between the t-th index and the survey score of the scholars' degree of interdisciplinarity, and std(X t ) and std(g) respectively represent X tThe standard deviation of and g, the value range of R is (-1,1), and the candidate index items whose R is greater than the predetermined value are selected to obtain T′ candidate index items:

[0159] (x i1 ,x i2 ,x it …x iT′ )0≤i <C

[0160] In the implementation manner of the present application, candidate index items with R greater than 0.7 are selected to obtain T′ candidate index items.

[0161] Since there are correlations between the index items, it is necessary to remove duplicates of the index items. The specific method is to calculate the correlation between T′ candidate index items. The formula is as follows:

[0162]

[0163] Among them, cov(X t′ ,X t ) represents the covariance between the t′jth index and the tth index, std(X t′ ) and std(X t ) represent X t′ and X t The standard deviation, R t′t The value range is (-1,1), select R t′t The candidate index items within the predetermined range are the final evaluation index items. Specifically, select R t′t The index item t′j and the index item t in the range of (-1, -0.7) and (0.7, 1) are the final evaluation index items.

[0164] In the implementation manner of the present application, the multiple indicator items are academic conferences participated in, conference papers published, academic collaborators and cited literature.

[0165] Specifically, academic conferences in which scholars participate include two types of conferences: one is conferences where scholars serve as organizers or reviewers, and the other is conferences where scholars publish papers. The degree of interdisciplinarity of conferences in which scholars serve as organizers or reviewers can, to a certain extent, reflect the academic interdisciplinarity of scholars. Scholars as organizers must have interdisciplinary resources and interdisciplinary knowledge to be able to play an organizational or planning role in such academic conferences. The degree of interdisciplinarity of conferences in which scholars publish papers can reflect the degree to which scholars’ academic achievements are accepted by interdisciplinary conferences. The higher the degree of interdisciplinarity of such conferences, the more interdisciplinarity of scholars’ academic achievements can be reflected from the side.

[0166] The published conference papers are the academic achievements of scholars, and their interdisciplinary level directly reflects the scholars' interdisciplinary academic output ability.

[0167] There are two types of academic collaborators: those who collaborate with scholars to publish academic results, and those who undertake scientific research projects with scholars. The distribution of academic collaborators in disciplines shows the breadth and diversity of scholars' interdisciplinary collaboration.

[0168] Cited literature refers to the literature cited in conference papers. The interdisciplinary nature of the cited literature indicates the ability of scholars to read and draw on interdisciplinary ideas, theories and methods.

[0169] For step S2: obtain the data of the evaluation index items corresponding to the scholar to be evaluated.

[0170] Specifically, data on academic conferences participated in, conference papers published, academic collaborators, and cited literature of the scholars to be evaluated are obtained.

[0171] The data for this application is mainly obtained from the personal homepages of scholars. The information on personal homepages is generally maintained by the scholars themselves. On the one hand, the data is more comprehensive and timely, and on the other hand, the data is more accurate.

[0172] To collect information about academic conferences, we first directly mine the conference information maintained on personal websites. Scholars mainly participate in the organization of conferences as editorial board members, chairmen, and editors-in-chief. Natural language processing is used to obtain conference names through deep learning models.

[0173] The second is the conference where scholars publish papers. Since the academic paper model maintained by personal websites is relatively standardized, the list of academic papers is obtained through keywords, and the conference name is obtained from the paper list.

[0174] Obtain academic conferences attended by scholars through the above two methods.

[0175] Data collection of published conference papers was obtained directly through the paper lists maintained on personal websites.

[0176] Academic collaborators are collected through personal websites. First, the published papers are obtained to obtain the list of authors of the papers and obtain the author names by segmentation; second, the author information listed in the published works;

[0177] Cited literature collection is obtained by obtaining the list of cited literature listed in published academic papers.

[0178] Construct a subject library and form a complete subject library S by collecting classification information of higher education subjects.

[0179] For step S3: the interdisciplinary degree index scores of the plurality of evaluation index items are calculated by using the acquired data of the evaluation index items.

[0180] Specifically, the interdisciplinary index scores for participating academic conferences, publishing conference papers, academic collaborators, and cited literature are calculated.

[0181] In the implementation mode of this application, the specific method for calculating the interdisciplinary degree index score corresponding to the academic conference participated in is:

[0182] The degree of interdisciplinarity of academic conferences in which scholars participate is obtained by statistically analyzing the interdisciplinarity of papers published in the academic conferences in the past three years.

[0183] Obtain the papers published in the academic conferences you participated in in the past three years.

[0184] Classify the papers by subject, extract the keywords of the papers, and input the keywords into the pre-trained RNN recurrent neural network of the subject classification;

[0185] The input is the jth keyword vector, and the output is a probability vector y of length n after the sofmax function. j , n is the number of subjects, and the subject to which keyword j belongs is:

[0186] S j =findSubject(S,y j )

[0187] Where findSubject is based on the subject library S and the probability vector yy j Obtain subject information.

[0188] By analyzing all the keywords in the paper, we can get the interdisciplinary distribution of the paper:

[0189] S ifk ={S1,S2…,S m}

[0190] Among them, k is the kth paper, i is the i-th scholar, f is conference f, and m is the number of disciplines. By counting all the papers of conference f, we can get the distribution of disciplines of conference f:

[0191] S if ={S1,S2…,S n}

[0192] And get the interdisciplinary number distribution D of all papers corresponding to conference f if ,as follows:

[0193] D if ={d if1 ,d if2 …d ifj …difn}

[0194] Where n is the number of disciplines associated with conference f, d ifj To count the number of times conference f in which scholar i participated appeared in the jth discipline.

[0195] According to D if Calculate the Brillouin index H if As the interdisciplinary diversity of the conference, the Brillouin index is a classic indicator for measuring diversity. It is based on the calculation principle of information entropy and its formula is as follows:

[0196]

[0209] Among them, V ifj is d ifj Representative SubjectS j The word embedding vector, V ifk is d ifk Representative SubjectS k The word embedding vector of .

[0210] The degree of interdisciplinaryness of a conference is calculated by averaging the diversity, balance, and differences. The calculation formula is as follows:

[0211]

[0212] After calculating the interdisciplinary level of all academic conferences participated by the scholar to be evaluated, the average is added up to obtain the average interdisciplinary level of the academic conferences participated by the scholar, which is used as the interdisciplinary level index score of the scholar's academic conference.

[0213]
