A model LSI-BERT based on BERT and fused lexical and syntactic information (LSI) is proposed to address the shortcomings of the existing end- to- end aspect-based sentiment analysis (E2E-ABSA) method research that does not fully utilize textual information. A BERT embedding layer and a TFM feature extractor are used to extract semantic information, and lexical information is extracted by the industrial- grade natural language processing tool SpaCy. Two weighting factors α and β are introduced to fuse semantic and lexical information. Graph attention networks (GAT) is used to extract syntactic dependency information based on the adjacency matrix generated from the syntactic dependency tree. A dual-stream attention network is used to fuse syntactic dependency information and textual information fused with lexical information to achieve better interaction between these two types of information. The experimental results show that the model outperforms the current representative model on three commonly used benchmark datasets. [ABSTRACT FROM AUTHOR]

Poetry discloses the fundamentals of truths and values about lives. Tourism in its purpose enhances tourists' well-being through inhabiting the environments of poetics and authenticity compared to everydayness. This study employs a hermeneutic phenomenological analysis of Three Hundred Tang Poems, guided by Heidegger's ideas of Dasein and being-in-the-world, to explore the intrinsic connection between poetry and tourism. This study also proposes a conceptual framework of 'tourist being-in-the-world'. Through the manual qualitative identification method, the findings reveal that: (a) the interpretation of the tourism essence should be grounded on the existential state of human being; (b) tourist being-in-the-world should be considered as a constitution of Dasein, as the most connotations in Three Hundred Tang Poems are associated with tourism (86.9%). Seeing life as a journey, men are born tourists in philosophy, who make sense of the experience of a tourist being-in-the-world (the appearance of authentic selves). Our findings elucidate how tourism destinations were depicted, manifested, and transcended by the Tang Poetry and highlight that the traditional Eastern ideologies of 'nature as humanity' and 'humanized nature in the sense of spirituality' were embedded in tourism.

Because wireless sensor networks (WSNs) are becoming increasingly integrated into daily life, solving the energy efficiency problem of such networks is an urgent problem. Many energy-efficient algorithms have been proposed to reduce energy consumption in traditional WSNs. The emergence of software defined networks (SDNs) enables the transformation of WSNs. Some SDN-based WSNs architectures have been proposed and energy-efficient algorithms in SDN-based WSNs architectures have been studied. In this paper, we integrate an SDN into WSNs and an improved software-defined WSNs (SD-WSNs) architecture is presented. Based on the improved SD-WSNs architecture, we propose an energy-efficient algorithm. This energy-efficient algorithm is designed to match the SD-WSNs architecture, and is based on the residual energy and the transmission power, and the game theory is introduced to extend the network lifetime. Based on the SD-WSNs architecture and the energy-efficient algorithm, we provide a detailed introduction to the operating mechanism of the algorithm in the SD-WSNs. The simulation results show that our proposed algorithm performs better in terms of balancing energy consumption and extending the network lifetime compared with the typical energy-efficient algorithms in traditional WSNs.
