Natural and Artificial Concepts

Natural and Artificial Concepts

In psychology, concepts can be divided into two categories: natural and artificial. Natural concepts are formed through direct or indirect experiences. For example, consider the concept of snow. If you live in a place with regular snowfall, such as Essex Junction, Vermont, you know snow through direct experiences. You’ve seen it fall, touched it, shoveled it, and played in it. You recognize its texture, appearance, and even its smell. In contrast, if you live on an island like Saint Vincent in...

Concepts of Health and Illness

Concepts of Health and Illness

Health is a condition of the body, mind, and spirit where an individual remains free from illness. Similarly, wellness is an active state, including living a lifestyle that promotes physical, mental, and emotional health. Physical health is critical for the overall well-being and can be affected by lifestyle, activity level, diet, and behavior. The highest attainable standard of health is a fundamental and universal human right. Consider Lisa, a fifteen-year-old born with congenital...

Extraction: Advanced Methods

Extraction: Advanced Methods

Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is formed in...

Concepts and Prototypes

The human nervous system handles vast amounts of information by translating sensory stimuli into neural impulses, which the brain processes, creating thoughts expressed through language or stored as memories. The brain also synthesizes information from emotions and memories, which significantly influence thoughts and behaviors. This intricate process creates a comprehensive mental picture.
The brain organizes this information using concepts, which are mental categories grouping linguistic data,...

Basic Concept

Basic Concept

Engineering mechanics is a branch of engineering that studies motion and the forces acting on objects. It is a fundamental subject and forms the basis of many other engineering disciplines. Length, time, mass, and force are some basic concepts in engineering mechanics.
Length, which measures the distance traveled by an object, is a fundamental concept in engineering mechanics. We use coordinates relative to a reference point to describe the distance. Length not only helps to describe the...

SBAR I: Understanding the Concept

Effective communication among healthcare professionals during hand-off reporting is essential to delivering safe and continuous patient care. Common professional interactions include reports to healthcare team members, hand-off, and transfer reports. Nurses routinely report information to other healthcare team members and also urgently contact healthcare providers to report changes in patient status.
Standardized methods of communication have been developed to ensure that information is...

Area of Science:

Biomedical Informatics
Natural Language Processing
Data Visualization

Background:

Extracting knowledge from unstructured biomedical texts is challenging.
Existing methods often fail to reveal key concepts and semantic relationships.
Computers struggle to interpret information in semi-structured and unstructured text.

Purpose of the Study:

To present a novel Biomedical Knowledge Extraction and Visualization framework, BioKEVis.
To identify key information components centered on concepts from biomedical documents.
To facilitate understanding of conceptual structures and semantic relationships in text corpora.

Main Methods:

Utilized linguistic analysis and Latent Semantic Analysis (LSA) for concept identification.
Integrated a biomedical named entity recognizer (ABNER) for tagging entities like genes and proteins.
Developed a method for collating information into a semantic network for navigation and comprehensive views.

Main Results:

BioKEVis successfully identifies key information components from biomedical texts.
Generated semantic networks provide user-navigable perspectives on document collections.
A structured repository and query-processing module enable efficient biomedical text querying.

Conclusions:

BioKEVis offers an effective approach to biomedical knowledge extraction and visualization.
The framework enhances the understanding of complex biomedical information.
Semantic networks and structured repositories improve information retrieval and analysis.
