Self-Concept01:19

Self-Concept

1.7K
Self-concept is the cognitive and emotional understanding individuals hold about their identity. It evolves through various developmental stages, beginning in infancy and maturing as children grow. This concept influences how individuals perceive their abilities, interact with others, and manage challenges throughout life.
Infancy and Emerging Recognition
During infancy, self-concept is virtually nonexistent. Babies do not distinguish themselves as separate entities and often mistake their...

Framing Effects

8.0K
Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in...

Concepts and Prototypes

574
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,...

Concept of Pressure at a Point01:15

Concept of Pressure at a Point

795
The concept of pressure at a point in a fluid establishes that pressure within a fluid is uniform in all directions at a specific location. This uniformity occurs because fluid molecules exert force evenly across any point due to their random motion and continuous collisions within the fluid. Pressure at a point is determined by the surrounding fluid molecules and is influenced by factors like depth and density, rather than by shape or orientation.
In a fluid at rest, pressure acts equally in...

Understanding Self-Concept01:20

Understanding Self-Concept

314
The self-concept encompasses individuals' beliefs about themselves, structured through cognitive frameworks known as self-schemas. These schemas function as mental representations of specific traits or behaviors, influencing how self-relevant information is perceived, processed, and remembered. For example, individuals who are schematic for body weight are more likely to interpret routine experiences—such as dining out or shopping—through the lens of that trait. Conversely, those...

Area of Science:

  • Bioinformatics
  • Natural Language Processing (NLP)

Background:

  • Concept mapping is crucial in NLP for bioinformatics, often utilizing the UMLS Metathesaurus.
  • Query expansion with synonyms (element synonyms) enhances recall in UMLS concept mapping.
  • The quality and completeness of element synonyms directly impact application success.

Purpose of the Study:

  • To develop an improved system for element synonym acquisition.
  • To enhance the performance and quality of synonym resources for concept mapping.

Main Methods:

  • The Lexical Systems Group (LSG) developed a new system for element synonym acquisition.
  • The system was designed with enhanced requirements for better performance.
  • The newly acquired synonyms were integrated into the lexSynonym resource.

Main Results:

  • The 2017 release of the Lexicon (lexSynonym) showed a 36.71-fold increase in synonyms.
  • Concept mapping demonstrated improved recall and F1 scores using the new lexSynonym.2017.
  • Precision remained comparable, indicating enhanced coverage without sacrificing accuracy.

Conclusions:

  • The new element synonym acquisition system significantly expands synonym coverage and quality.
  • This advancement positively impacts NLP applications in bioinformatics, particularly UMLS concept mapping.
  • The enhanced lexSynonym resource offers a more robust foundation for biomedical text analysis.
