Summary
Information content measures assess terminological systems like SNOMED CT and medical records. These methods evaluate system structure and data content, proving useful for healthcare informatics.
Area of Science:
- Medical Informatics
- Information Science
Background:
- Terminological systems, such as SNOMED CT, are crucial for modern healthcare record-keeping.
- Assessing the content and structure of these systems and the medical records within them is essential.
Purpose of the Study:
- To explore the utility of information content as a metric for evaluating terminological systems and medical record content.
- To propose and apply novel information-content-based measures.
Main Methods:
- Developed two measures for terminological systems: proportion of concepts with zero information content and average information content.
- Applied these measures to recent SNOMED CT releases.
- Described two measures to estimate the content of terminologically captured medical records.
Main Results:
- The proposed measures effectively indicate the overall structure of terminological systems or specific subsets.
- Information content provides a valuable basis for assessing both terminological system structure and medical record content.
Conclusions:
- Information content is a robust metric for analyzing the structure of terminological systems.
- This approach offers a reliable method for estimating the content captured in medical records using these systems.

01:20Anatomical Terminology
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,...
01:29Measures of Intelligence
Psychologists measure intelligence by using standardized tests that produce a score known as the intelligence quotient or IQ. To understand IQ tests, it's important to recognize the key principles behind their construction: validity, reliability, and standardization.
Validity refers to how well a test measures what it claims to measure. An intelligence test should accurately assess intelligence rather than another characteristic, like anxiety. Criterion validity is one way to evaluate this; it...

00:56Nominal Level of Measurement
The way a set of data is measured is called its level of measurement. Correct statistical procedures depend on a researcher being familiar with levels of measurement. Not every statistical operation can be used with every set of data. For analysis, data are classified into four levels of measurement—nominal, ordinal, interval, and ratio.
The data that cannot be measured but can be grouped into categories fall under the nominal level of measurement. Data that is measured using a nominal scale is...

01:19Encoding
Information enters the brain through encoding, which is the input of information into the memory system. Once sensory information is received from the environment, the brain labels or codes it. The information is then organized with similar information and connected to existing concepts. Encoding occurs through automatic processing and effortful processing.
Automatic processing involves the encoding of details like time, space, frequency, and the meaning of words, usually done without conscious...

03:02Measurement: Derived Units
The International System of Units or SI system, by international agreement, has fixed measurement units for seven fundamental properties: length, mass, time, temperature, electric current, amount of substance, and luminosity. These are called the SI base units.
01:23System of Memory
Memory is categorized into three major systems: sensory memory, short-term memory (STM), and long-term memory (LTM). These systems differ in their capacity and the duration for which they can hold information. Sensory memory captures raw sensory input from the environment, holding it for just a few seconds or less. For example, on hearing a brief, loud sound, like a car horn honking, the sound seems to linger in the mind for a moment even after it stops. This is an instance of sensory memory...
