Abstract： [Purpose/significance] Identifying expertise tags of scholars is the most critical task in scholar profiling. Expertise tags contribute to finding peer experts, clustering domain scholars and selecting reviewers.[Method/process] This study analyzed related factors on the scholar expertise in academic publications, then constructed a hierarchical analysis model on the weight allocation of the factors. The TextRank algorithm has been used to identify topical terms in Chinese corpus, and the conceptual linking technique in English corpus. The extracted terms, together with the previously analyzed factors have been combined to select the expertise tags of the scholars. In this study, a group of honored scholars of different domains have been selected. Their research expertise information from their resumes have been taken as evaluation benchmark. And the expertise tags extracted from their publications have been compared with the benchmark by human judgment and additional semantic similarity judgment.[Result/conclusion] The evaluation shows that the expertise tags of 71.9% scholars are acceptable for Chinese, and 77.2% for English. The experiment proves that the method proposed in this article is pragmatic and may lead to reasonable results. The chief innovation of this study lies in three aspects, Firstly, term extraction approaches that suit to different application conditions have been explored, such as the language of publication and the availability of domain knowledge base. Secondly, multiple features have been combined together to identify the expertise tags of scholars, including the content of publications, the substantial contribution to the publications of the scholars, and the influence to the domain of the publications. Thirdly, a reasonable experimental design and evaluation method is proposed, and the proposed approach has been verified by combining manual scoring and semantic calculation results.

Abstract： Background In recent years，the prevalence of degenerative spinal deformity（DSD） has been increasing annually. Patients have to live with DSD for a long time from the onset of disease until surgical intervention is required，and self-management during this period is crucial for the development and progression of DSD. However，the current status and influencing factors of self-management in DSD patients remain unclear，making it difficult to tailor effective intervention measures. Objective To investigate the current status and influencing factors of self-management in patients with DSD，so as to provide a clinical reference for the development of targeted intervention programs. Methods A total of 200 patients with DSD who attended the department of orthopedics in the first Affiliated Hospital of the Army Medical University from June 2020 to December 2022 using a convenience sampling method to conduct questionnaire survey. The demographic information，Visual Analogue Scale（VAS） score，Oswestry Disability Index（ODI） score，Medical Outcomes Study Social Support Survey（MOS-SSS） score，and Chronic Disease Self-management Behavior Scale score were collected. Multiple linear regression were used to analyze the influencing factors of chronic disease self-management behaviors of patients. Results A total of 191（95.5%） valid questionnaires were recovered. The average age of the patients was（62.6±11.6） years，including 144 cases（75.4%） of scoliosis，37 cases（19.4%） of kyphosis and 10 cases（5.2%） of lateral kyphosis. The total score of self#2;management behaviors was（22.94±11.97）. Thestandardized scores for each dimension of self-management behaviors were cognitive symptom management（26.27±15.83），doctor-patient communication（23.53±16.27） and exercise（18.42±11.00） in descending order. The results of correlation analysis showed that age，BMI，monthly per capita household income，education level，smoking history，function disorder and medical social support were significantly correlated with the scores of each dimension and total score of Chronic Disease Self-management Behavior Scale（P<0.05）. The multiple linear regression analysis results showed that medical social support，education level，monthly per capita household income，and bone mineral density were influencing factors of Chronic Disease Self-management Behavior Scale scores（P<0.05）. Conclusion The level of self#2;management behavior in patients with DSD is low. Medical social support，education level，economic level，and bone mineral density are the main influencing factors of self-management behaviors. Healthcare providers should improve self-management behaviors of DSD patients in clinical practice to help them manage their diseases effectively by strengthening education and enhancing social support.
