Identifying multidisciplinary problems from scientific publications based on a text generation method

Journal of Data and Information Science 2024年第3期9卷 213-237页

Purpose:A text generation based multidisciplinary problem identification method is proposed,which does not rely on a large amount of data ***/methodology/approach:The proposed method first identifies the research objective types and disciplinary labels of papers using a text classification technique;second,it generates abstractive titles for each paper based on abstract and research objective types using a generative pre-trained language model;third,it extracts problem phrases from generated titles according to regular expression rules;fourth,it creates problem relation networks and identifies the same problems by exploiting a weighted community detection algorithm;finally,it identifies multidisciplinary problems based on the disciplinary labels of ***:Experiments in the“Carbon Peaking and Carbon Neutrality”field show that the proposed method can effectively identify multidisciplinary research *** disciplinary distribution of the identified problems is consistent with our understanding of multidisciplinary collaboration in the *** limitations:It is necessary to use the proposed method in other multidisciplinary fields to validate its *** implications:Multidisciplinary problem identification helps to gather multidisciplinary forces to solve complex real-world problems for the governments,fund valuable multidisciplinary problems for research management authorities,and borrow ideas from other disciplines for ***/value:This approach proposes a novel multidisciplinary problem identification method based on text generation,which identifies multidisciplinary problems based on generative abstractive titles of papers without data annotation required by standard sequence labeling techniques.

Body dynamic interference is one of the common phenomena in the process of vehicle road *** is easy to cause sensitive and disgusting problems such as knock off paint,friction deformation,noise and so *** on the principle of direct method,this paper studies the theory of multi degree of freedom forced vibration,the algorithm and process of time-domain transient response analysis,and puts forward a dynamic interference method for vehicle body,which adopts the self-developed DIA（dynamic interference）*** load input,modeling analysis,diagnosis and optimization of the system are carried out,and the system is applied to the trunk lid system to identify and optimize the problem more *** method can be extended to the prediction of dynamic interference among vehicle,subsystem and parts.
