Vector Algebra: Graphical Method

15.4K
Vectors can be multiplied by scalars, added to other vectors, or subtracted from other vectors. The vector sum of two (or more) vectors is called the resultant vector or, for short, the resultant.
We use the laws of geometry to construct resultant vectors, followed by trigonometry to find vector magnitudes and directions. For a geometric construction of the sum of two vectors in a plane, we follow the parallelogram rule. Suppose two vectors are at arbitrary positions. Translate either one of...

Structural Classification of Joints01:20

Structural Classification of Joints

5.1K
Joints, also known as articulations, are classified based on their structural characteristics, i.e., based on whether the articulating surfaces of the adjacent bones are directly connected by fibrous connective tissue or cartilage, or whether the articulating surfaces contact each other within a fluid-filled joint cavity. These differences serve to divide the joints of the body into three structural classifications.
A fibrous joint is where the adjacent bones are united by fibrous connective...

Protein Networks02:26

Protein Networks

4.2K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Causes of Similarity-Dissimilarity Effect

47
The similarity-dissimilarity effect, a fundamental concept in social psychology, explains how interpersonal similarities and differences influence attraction and social interactions. This effect is supported by three key psychological perspectives: balance theory, social comparison theory, and consensual validation.Balance Theory and Cognitive ConsistencyBalance theory, developed by Fritz Heider, posits that individuals seek cognitive consistency in their relationships. When two people share...

Ogive Graph01:07

Ogive Graph

6.1K
An ogive graph is sometimes called a cumulative frequency polygon. It is one type of frequency polygon that shows cumulative frequency. In other words, the cumulative percentages are added to the graph from left to right. An ogive graph plots cumulative frequency on the vertical y-axis and class boundaries along the horizontal x-axis. It’s very similar to a histogram; only instead of rectangles, an ogive displays a single point where the top right of the rectangle would be. Creating this...

Deductive Reasoning01:16

Deductive Reasoning

62.1K
Deductive reasoning, or deduction, is the type of logic used in hypothesis-based science. In deductive reasoning, the pattern of thinking moves in the opposite direction as compared to inductive reasoning, which means that it uses a general principle or law to predict specific results. From those general principles, a scientist can deduce and predict the specific results that would be valid as long as the general principles are valid.
For example, a researcher can deduce specific predictions...

Area of Science:

  • Artificial Intelligence
  • Data Science
  • Natural Language Processing

Background:

  • Entity disambiguation is crucial for knowledge graph accuracy.
  • Current methods often overlook the structural context of knowledge graphs.
  • This limitation hinders the capture of global semantic features for entities.

Purpose of the Study:

  • To enhance entity disambiguation by integrating graph structural information.
  • To improve the precision and recall of matching ambiguous entities to knowledge graphs.
  • To introduce a novel method that leverages both entity and graph embeddings.

Main Methods:

  • Propose EDEGE (Entity Disambiguation based on Entity and Graph Embedding).
  • Utilize semantic embedding vectors for entity relationships and subgraph structures.
  • Employ a graph neural network with balanced entity and graph embeddings for matching.

Main Results:

  • The EDEGE method significantly improves entity disambiguation performance.
  • Achieved 9.2% higher Precision, 7% higher Recall, and 11.2% higher F1-score on the ACE2004 dataset compared to baselines.
  • Demonstrated effectiveness in capturing global semantic features through experimental validation.

Conclusions:

  • EDEGE effectively addresses the limitations of context-based entity disambiguation.
  • Integrating graph structure and entity relationships enhances disambiguation accuracy.
  • The proposed method offers a more robust approach to knowledge graph entity matching.
