Deductive Reasoning01:16

Deductive Reasoning

70.7K
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...

Inductive Reasoning

Inductive reasoning is a form of logical thinking that uses related observations to arrive at a general conclusion. It is uncertain and operates in degrees to which the conclusions are credible. As such, inductive arguments can be weak or strong, rather than valid or invalid, and conclusions can be used to formulate testable, falsifiable hypotheses.
Inductive reasoning is common in descriptive science. A life scientist makes observations and records them. This data can be qualitative or...

Cognitivism

3.2K
Cognitive psychology emerged as a significant field in the mid-20th century. It focused on understanding humans' internal mental processes. This approach emphasizes how people perceive, remember, think, and solve problems—elements critical to human cognition.
Previously dominated by behaviorism, which prioritized observable behaviors and largely ignored mental processes, psychology transformed in the 1950s. Cognitive psychologists argue that understanding how we think and process...

Hindsight Biases

4.5K
Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?

Natural and Artificial Concepts01:24

Natural and Artificial Concepts

619
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...

Spanning Openings in Brick Walls

597
In brick wall construction, supporting structures are crucial for openings like windows and doors to maintain the integrity and support the weight of the wall above. These supports include lintels, corbels, and arches, each serving specific structural purposes.
Lintels are primary supports used to span openings and can be crafted from materials such as reinforced concrete, steel-reinforced brick masonry, or simple steel angles. These are straightforward to install and are typically concealed...

Summary
This summary is machine-generated.

This study demonstrates that knowledge embeddings effectively capture both common-sense and domain-specific knowledge, such as medical information. Acquired common-sense knowledge showed less neutrality and plausibility compared to medical knowledge.

Area of Science:

  • Natural Language Processing
  • Knowledge Representation
  • Machine Learning

Background:

  • Language comprehension relies on common-sense and domain-specific knowledge.
  • Open information extraction and knowledge embeddings are key to capturing this knowledge.
  • Knowledge graphs represent concepts and relations for learning embeddings.

Purpose of the Study:

  • To acquire and represent common-sense and medical knowledge using knowledge embeddings.
  • To evaluate the effectiveness of a unified knowledge acquisition methodology.
  • To compare the characteristics of acquired common-sense and medical knowledge.

Main Methods:

  • Utilized open information extraction techniques to build knowledge graphs.
  • Employed knowledge embeddings to represent concepts and relations.
  • Acquired common-sense knowledge from blogs, books, and WordNet.
  • Acquired medical knowledge from electronic health records.

Main Results:

  • The knowledge acquisition methodology using knowledge embeddings proved effective for both common-sense and medical knowledge.
  • Learned knowledge embeddings captured semantic compositionality and implied knowledge.
  • Acquired common-sense knowledge was less neutral and less plausible than medical knowledge.
  • Differences in neutrality and plausibility reflect the complexities of common-sense knowledge acquisition.

Conclusions:

  • Knowledge embeddings offer a robust method for acquiring diverse forms of knowledge.
  • The methodology is adaptable for both general common-sense reasoning and specialized domains like medicine.
  • Further research is needed to address the nuances and challenges in acquiring common-sense knowledge.
