Cohesion01:07

Cohesion

60.3K
Cohesion is the attraction between molecules of the same type, such as water molecules. Water molecules have an overall neutral charge but are polar molecule. An oxygen atom in one water molecule has a partial negative charge that can bind to a hydrogen atom with a partial positive charge in a second water molecule, forming a hydrogen bond. Each water molecule can form up to four hydrogen bonds with other water molecules. Hydrogen bonds are responsible for water's cohesive nature.

Correlation and Causation01:27

Correlation and Causation

43.6K
Statistical tests can calculate whether there is a relationship, or correlation, between independent and dependent variables. An indirect relationship of the variables signifies a correlation, while a direct relationship shows causation. If it is determined that no connection exists between the variables, then the correlation is a coincidence.
Correlation versus Causation
If the dependent variable increases or decreases when the independent variable increases, there is a positive or negative...

Van der Waals Interactions01:24

Van der Waals Interactions

72.7K
Atoms and molecules interact with each other through intermolecular forces. These electrostatic forces arise from attractive or repulsive interactions between particles with permanent, partial, or temporary charges. The intermolecular forces between neutral atoms and molecules are ion–dipole, dipole–dipole, and dispersion forces, collectively known as van der Waals forces.

Viral Structure00:56

Viral Structure

75.4K
Viruses are extraordinarily diverse in shape and size, but they all have several structural features in common. All viruses have a core that contains a DNA- or RNA-based genome. The core is surrounded by a protective coat of proteins called the capsid. The capsid is composed of subunits called capsomeres. The capsid and genome-containing core are together known as the nucleocapsid.

Frequency-dependent Selection01:21

Frequency-dependent Selection

24.4K
When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.

Area of Science:

  • Computational linguistics
  • Network science
  • Stylometry

Background:

  • Complex network theory aids authorship identification without semantic knowledge.
  • Previous studies focused on large text networks; suitability for small text chunks was less explored.

Purpose of the Study:

  • Introduce a methodology using word co-occurrence network dynamics for text classification.
  • Assess the effectiveness of network metrics in capturing authorship stylistic features.

Main Methods:

  • Texts were segmented into equal linguistic token sections.
  • Time series of 12 network topological metrics were generated.
  • Distribution moments of stationary/integrable network metrics were used as features.

Main Results:

  • A supervised learning procedure with Isomap nonlinear transformation and K-nearest neighbors was employed.
  • 71 out of 80 texts (88.75%) were correctly classified by author.
  • Dynamic fluctuations in network metrics proved effective for authorship characterization.

Conclusions:

  • Dynamic network metrics offer a robust method for authorship attribution.
  • This approach enables the description of large texts using small, evolving networks.
