Summary
Wikipedia covers 80% of clinical concepts, offering a promising resource for building an open clinical terminology. This study explored Wikipedia
Area of Science:
- Medical Informatics
- Bioinformatics
- Computational Linguistics
Background:
- Clinical terminologies are vital for semantic interoperability in electronic health records.
- Existing terminologies face challenges like content gaps and slow update cycles, impacting data quality.
- There is a need for efficient methods to develop and maintain comprehensive clinical terminologies.
Purpose of the Study:
- To evaluate Wikipedia's content coverage as a source for bootstrapping an open clinical terminology.
- To assess the feasibility of using community-driven resources for clinical knowledge representation.
- To determine the extent to which clinical concepts are represented in Wikipedia.
Main Methods:
- Manual mapping of a clinically relevant subset of SNOMED CT concepts to Wikipedia articles.
- Expert clinical terminologists performed the mapping process.
- Analysis of coverage and composability of clinical concepts within Wikipedia.
Main Results:
- Approximately 80% of the evaluated SNOMED CT concepts have coverage in Wikipedia.
- Many concepts without direct Wikipedia matches can be composed from multiple articles.
- Wikipedia demonstrates significant potential for representing clinical terminology content.
Conclusions:
- Wikipedia is a suitable resource for bootstrapping an open clinical terminology.
- The high coverage suggests Wikipedia can aid in addressing content gaps in existing terminologies.
- Further research can explore automated methods for extracting clinical concepts from Wikipedia.

26.4K
Knowledge of anatomy is essential to understand human biology and medicine. Anatomists and health care professionals use standard terminology to describe the human body with more precision and no ambiguity. Anatomical terms have mostly Greek and Latin-derived roots. Because these languages are rarely used in conversation, the meaning of words remains the same. Each term is made up of a root in between the prefixes and suffixes. The root of a term often refers to an organ, tissue, or condition,...

01:14Circuit Terminology
2.8K
An electrical network is a system composed of interconnected elements, such as resistors, capacitors, inductors, and voltage or current sources. Unlike a circuit, an electrical network does not necessarily form a closed path. In other words, while all circuits can be considered networks due to their interconnected nature, not every network qualifies as a circuit.
A circuit, on the other hand, is also an interconnected system of electrical elements but must contain one or more closed paths.

Chromatography is an analytical technique widely used in fields such as chemistry, biology, environmental science, and pharmaceuticals to separate the components of a mixture and identify substances between them. The process of chromatography is based on the interactions between two distinct phases: the stationary phase and the mobile phase. The stationary phase is fixed in place by a supporting material, while the mobile phase moves over it, carrying the solutes. As the mobile phase travels,...

Clinical trials are prospective experimental studies conducted on humans to determine the safety and efficacy of treatments, drugs, diet methods, and medical devices. Using statistics in clinical trials enables researchers to derive reasonable and accurate conclusions from the collected data, allowing them to make wise decisions in uncertain situations. In medical research, statistical methods are crucial for preventing errors and bias.
