A conceptual similarity and correlation discrimination method based on HowNet

The similarity and correlation analysis of word concepts has a wide range of applications in natural language processing, and has important research significance in information retrieval, text classification, data mining, and other application fields. This paper analyzes and summarizes the information of sememes relationship through the definition of words in HowNet and proposes a method to distinguish the similarity and correlation of words. Firstly, using a combination of the part of speech and sememes to distinguish the similarity and correlation between words concept. Secondly, the similarity and correlation calculation results between vocabulary concepts are used to further optimize the judgment results. Finally, the similarity and correlation distinction and discrimination between vocabulary concepts are realized. The experimental results show that the method reduces the complexity of the algorithm and greatly improves the work efficiency. The semantic similarity and correlation judgment results are more in line with the human intuitive experience and improve the accuracy of computer understanding of natural language. which provides an important theoretical basis for the development of natural language

Flexible self-supporting interconnected cobalt sulfide nanosheets enable high-loading and long-cycling Li-S batteries with high areal capacity

Lithium-sulfur batteries (LSB) with high theoretical specific capacity/energy density still face some practical challenges, for instance shuttle effect and sluggish redox kinetics, which leads to rapid capacity decay. To overcome these challenges, herein, a porous and flexible sulfur host composed of interconnected Co9S8 nanosheets grown on carbon cloth was constructed. The interconnected carbon fiber skeleton and porous conductive Co9S8 nanosheets can not only provide abundant electron/ion-transport channels, but also offer adequate void to accommodate volume expansion of sulfur, thus ensuring high sulfur utilization and remarkable cycle stability of electrode. Meanwhile, the abundant adsorption and catalytic sites provided by Co9S8 nanosheets can effectively inhibit dissolution of polysulfides and improve conversion kinetics of polysulfides, effectively suppressing “shuttle effect”. The Co9S8-CC/Li2S6 electrode achieves high discharge capacity (1315.1 mAh g−1, 0.1C), excellent rate capability (872.4 mAh g−1, 2C) and outstanding cyclic stability (decay of 0.02 %/cycle over 1500 cycles, 2C)
