A bibliographic co-occurrence analysis system(BICOMB software) was used to perform keyword word frequency analysis and generate a keyword co-occurrence matrix. In addition, Ucinet software's Netdraw tool was used to create visualized network diagrams.Results: A total of 27890 articles were retrieved, and word frequency analysis revealed that the highestfrequency keywords consisted of anxiety, depression, the elderly, expectant women, coronary heart disease, diabetes, breast cancer, perioperative period, quality of life, and psychological intervention.Research hotspot analysis revealed that consistent hotspots comprised anxiety, depression, health education, and perioperative period; expectant women became a hotspot during 2010-2012, and quality of life and efficacy became hotspots during 2013-2015.Conclusions: In addition to the care process, clinical psychological nursing research hotspots in China have increasingly included the effectiveness of psychological nursing and impact on patient quality of life. In addition, research hotspots have been influenced by the incidence of illnesses and people's health consciousness.展开更多

The approaches based on large corpus statistic Markov language model (such as bigram, trigram) become more and more popular today. This paper presents an improved Chinese word bigram, space-compressed Chinese word bigram, which stores the bi-word co-articulation frequency in the form of the bi-character co-articulation frequency. The bi-word co-articulation frequency is estimated from the bi-character co-articulation frequency library. The CPCC experiment with the improved Chinese word bigram shows: it can reach a higher correct conversion ratio with less space occupation.展开更多
