Intelligent recommendation system for College English courses based on graph convolutional networks.

With the rapid development of international communication, the number of English courses has shown an explosive growth trend, which has caused a serious problem of information overload, resulting in poor teaching performance of recommended English courses. To solve this problem, this paper proposes a graph convolutional neural network model based on College English course texts, students' major, English foundation and network structure characteristics. First, by analyzing the relevant data of College English courses and combining with graph neural network, an English course recommendation algorithm model based on the College English learning strategy of proximity comparison is proposed. Then, the College English texts are taken as feature input, and multi-layer graph convolutional neural network is used to process the above graph neural network structure. Attention mechanism is introduced to enhance the representation of graph features in College English skills. Finally, multi-layer attention model is used to process the courses that users have learned, and intelligent course recommendation is made by combining the multi-layer attention modeling of College English skills. The experimental data show that the proposed method achieves the best performance compared with the commonly used College English course recommendation method.

Intelligent recommendation system based on decision model of archive translation tasks.

How to recruit, test, and train the intelligent recommendation system users, and how to assign the archive translation tasks to all intelligent recommendation system users according to the intelligent matching principles are still a problem that needs to be solved. With the help of proper names and terms in China's Imperial Maritime Customs archives, this manuscript aims to solve the problem. When the corresponding translation, domain or attributes of a proper name or term is known, it will be easier for some archive translation tasks to be completed, and the adaptive archive intelligent recommendation system will also improve the efficiency of intelligent recommendation quality of archive translation tasks. These related domains or attributes are different labels of these archives. To put it simply, multi-label classification means that the same instance can have multiple labels or be labelled into multiple categories, which is called multi-label classification. With the multi-label classification, archives can be classified into different categories, such as the trade archives, preventive archives, personnel archives, etc. The system users are divided into different professional domains by some tests, for instance, system users who are good at economic knowledge and users who have higher language skills. With these labels, the intelligent recommendation system can make the intelligent match between the archives and system users, so as to improve the efficiency and quality of intelligent archive translation tasks. In this manuscript, through multi-label classification, the intelligent recommendation system can realize the intelligent allocation of archive translation tasks to the system users. The intelligent allocation is realized through the construction of intelligent control model, and verifies that the intelligent recommendation system can improve the performance of task allocation over time without the participation of task issuers.

Effect of methylphenidate hydrochloride combined with mentalization-based family therapy on clinical efficacy and social function in children with attention deficit hyperactivity disorder / 中华行为医学与脑科学杂志

Objective:To observe the effect of methylphenidate hydrochloride (MPH) combined with mentalization-based family therapy (MBFT) on clinical efficacy and social function in children with attention deficit hyperactivity disorder (ADHD).Methods:Sixty-four children with ADHD diagnosed in Wuxi Children's Hospital and Affiliated Hospital of Jiangnan University from June 2019 to May 2021 were selected and divided into observation group ( n=32) and control group ( n=32) according to the random number table.Children in both groups received methylphenidate hydrochloride extended-release tablets, while those in the observation group were given additional MBFT.The duration of treatment was 12 weeks in both groups.The parent symptom questionnaire (PSQ), swanson nolan and pelham-version Ⅳ (SNAP-Ⅳ) parent Al scale, and Weiss impairment functional scale (WFIRS-P) were used to evaluate the effectiveness of treatment.Statistical analysis was performed by SPSS 25.0 statistical software.In particular, the χ2 test was used for counting data and the paired sample t test was used for comparison of measurement data between the two groups before and after treatment. Results:(1) All the PSQ dimension scores of patients in the observation group and the control group after treatment were significantly lower than those before treatment (all P<0.01). Compared with the control group after treatment, the PSQ dimension scores of personality and behavior problems ((1.25±0.15), (0.94±0.18), t=7.484, P<0.001), learning problems ((1.57±0.16), (1.32±0.20), t=5.522, P<0.001), psychosomatic disorders ((0.56±0.11), (0.44±0.13), t=3.986, P<0.001), impulse hyperactivity ((1.76±0.23), (1.54±0.25), t=3.663, P<0.001), anxiety ((0.94±0.12), (0.76±0.11), t=6.255, P<0.001) and hyperactivity index ((1.74±0.19), (1.51±0.16), t=5.238, P<0.001) decreased significantly in the observation group after treatment.(2) Compared with the pre-treatment period, the SNAP-Ⅳ scale scores of attention deficit, impulsivity-hyperactivity and oppositional defiance were significantly lower in both groups after treatment (all P<0.01); and compared with the control group, the SNAP-Ⅳ scale scores of the above three dimensions were significantly lower in the observation group (all P<0.01). (3) All six dimensions (family, learning and school, life skills, self-management, social activities, and risk-taking activities)of the WFIRS-P scale were significantly lower in the children in the observation group after treatment compared with those before treatment (all P<0.01), and all the six dimensions of the WFIRS-P scale were significantly lower in the observation group compared with those in the control group (all P<0.01). Conclusion:Methylphenidate hydrochloride extended-release tablets combined with MBFT can significantly improve the clinical symptoms and social function of children with ADHD.
