Abstract： [Purpose/Significance] Relation extraction under academic full-text is the key technology for the construction of academic full-text knowledge graph. The constructed academic knowledge graph can realize the structure and knowledge of documents, and improve the efficiency of researchers retrieving documents, analyzing documents and grasping scientific research trends, and cognitive reasoning through graphs contributes to implicit knowledge discovery.[Method/Process] Enhancing relation extraction through external knowledge has achieved results in many studies, but relation extraction for specific fields often lacked available external knowledge. The research in this paper found that the high-confidence knowledge in the full-text could also be used to assist the extraction of full-text relations. For this reason, based on the dual-system theory of cognitive processes (system 1 is intuitive cognition, system 2 is reasoning cognition), this paper designed a sentence-level model to acquire knowledge, and obtained high-confidence knowledge through remote supervision, and then high-confidence knowledge was integrated into the final classification layer of the text-level deep learning model.[Result/Conclusion] On the biomedical academic full-text data set (CDR-revised), the F1 is about 11.13% higher than the current state-of-the-art model.

Abstract： [Purpose/significance] Online surrogate health information seeking is an everyday life information practice mode based on interpersonal cooperation. It is of great significance of deeply understanding the information behaviors to explore the influencing factors and mechanisms of this behavior based on the classical theories. [Method/process] Based on the health belief model and social support theory, this paper constructed the influencing factors model of surrogate health information seeking and put forward 12 research hypotheses. 475 valid data were collected through questionnaire survey and analyzed by SmartPLS. [Result/conclusion] The results show that empathy, information support intention, perceived severity and perceived benefits have positive impact on online surrogate health information seeking intention (OSHISI), while perceived barriers have a negative impact on OSHISI. Perceived susceptibility and self-efficacy have no direct relationship with OSHISI. The mediating effect analysis showed that the relationship between perceived susceptibility and OSHISI is completely mediated by empathy. Empathy plays a partial mediating role in the relationship between perceived severity and OSHISI. The relationship between self-efficacy and OSHISI is partially mediated by information support intention. The results of this study provide a reference for further motivating, managing and intervening online surrogate health information seeking practices.
