A Visualization Method of Knowledge Graphs for the Computation and Comprehension of Ultrasound Reports

Knowledge graph visualization in ultrasound reports is essential for enhancing medical decision making and the efficiency and accuracy of computer-aided analysis tools. This study aims to propose an intelligent method for analyzing ultrasound reports through knowledge graph visualization. Firstly, we provide a novel method for extracting key term networks from the narrative text in ultrasound reports with high accuracy, enabling the identification and annotation of clinical concepts within the report. Secondly, a knowledge representation framework based on ultrasound reports is proposed, which enables the structured and intuitive visualization of ultrasound report knowledge. Finally, we propose a knowledge graph completion model to address the lack of entities in physicians' writing habits and improve the accuracy of visualizing ultrasound knowledge. In comparison to traditional methods, our proposed approach outperforms the extraction of knowledge from complex ultrasound reports, achieving a significantly higher extraction index (η) of 2.69, surpassing the general pattern-matching method (2.12). In comparison to other state-of-the-art methods, our approach achieves the highest P (0.85), R (0.89), and F1 (0.87) across three testing datasets. The proposed method can effectively utilize the knowledge embedded in ultrasound reports to obtain relevant clinical information and improve the accuracy of using ultrasound knowledge.

Conference season

Health library and information workers no longer find themselves restricted to presenting at purely local or national health-related library events, a diversity evidenced by the two conferences supported by CILIP's Health Libraries Group this month, June 2019. The Health Libraries Group is an official sponsor of #EBLIP10, the 10th international Evidence Based Library and Information Practice conference, which encourages us to think about the evidence we collect and use to inform practice. The Health Libraries Group also strengthens its links with EAHIL: The European Association of Health Information and Libraries by aligning the content of this year's Virtual Issue of the Health Information and Libraries Journal with EAHIL 2019s themes of evidence-based practice, impact & assessment, and technology uptake, available at: https://bit.ly/2PAZw2X.
