Head and Tail Entity Fusion Model in Medical Knowledge Graph Construction: Case Study for Pituitary Adenoma
JMIR Medical Informatics
|May 31, 2021
Summary
A novel data fusion method creates a high-quality knowledge graph for pituitary adenoma (KGPA). This KGPA aids physicians by integrating diverse medical data for improved clinical practice and knowledge discovery.
Area of Science:
- Medical Informatics
- Artificial Intelligence in Medicine
- Data Science
Background:
- Pituitary adenoma is a common yet challenging central nervous system tumor.
- Diagnosis and treatment difficulties, including misdiagnosis and recurrence, are prevalent.
- A shortage of experienced neurosurgeons necessitates advanced support tools.
Purpose of the Study:
- To develop a data fusion method for integrating heterogeneous medical data.
- To construct a comprehensive knowledge graph for pituitary adenoma (KGPA).
- To enable knowledge discovery and support clinical decision-making.
Main Methods:
- Developed a framework for medical knowledge graph construction.
- Manually designed the KGPA schema.
- Extracted information from Chinese electronic medical records (CEMRs) and health portals using NLP and web scraping.
- Implemented an entity fusion method for heterogeneous data integration.
Main Results:
- Extracted data from 300 CEMRs and 4 health portals.
- Achieved high F1 scores for head (97.32%) and tail (98.57%) entity fusions.
- Evaluated KGPA triples, demonstrating 95.4% accuracy.
Conclusions:
- Introduced an effective approach for fusing triples from diverse data sources to build knowledge graphs.
- The constructed KGPA contains high-quality data.
- The KGPA can significantly assist physicians in clinical practice.

01:17The Pituitary Gland
8.2K
The pituitary is a small endocrine organ in the sphenoid bone under the hypothalamus. Primarily, the pituitary in adults has two distinct anatomical and functional regions— the anterior and posterior lobes. During human fetal development, a third pituitary gland region called the pars intermedia atrophies and disappears. However, some of its cells migrate and exist adjacent to the anterior pituitary in adults.

The adrenal or supra-renal glands, situated above the kidneys and aligned with the twelfth rib, are paired pyramid-shaped structures crucial for the body's stress response. During stress, these glands secrete hormones vital for adaptive physiological reactions.
These glands possess a distinctive yellow tinge due to the stored cholesterol and fatty acids required for hormone synthesis. They are encased in a fibrous capsule and cushioned by fat.

Adrenal gland disorders manifest when the production of adrenal hormones deviates from the norm, resulting in either excessive or insufficient concentrations.
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...
