Impact of Schemas

Impact of Schemas

Schemas are cognitive structures that provide a framework for interpreting and organizing social information. They help individuals navigate complex environments by offering expectations about people, events, and behaviors. Schemas influence attention, encoding, and retrieval processes, thereby shaping the entire trajectory of information processing in social contexts.Attention and Cognitive LoadDuring initial attention, schemas function as filters that prioritize schema-consistent information,...

Schemata

Schemata

A schema is a mental construct that organizes related concepts, allowing the brain to process information efficiently. Upon activation, schemata facilitate assumptions about people or objects.
Two types of schemata are:

Schemas

Schemas

A schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.

Structural Organization of the Human Body: An Overview

Structural Organization of the Human Body: An Overview

It is convenient to consider the body's structures in terms of fundamental levels of organization that increase in complexity: subatomic particles, atoms, molecules, organelles, cells, tissues, organs, organ systems, and organisms.
To study the chemical level of organization, scientists consider the simplest building blocks of matter: subatomic particles, atoms, and molecules. All matter in the universe is composed of one or more unique pure substances called elements, familiar examples of...

Genome Annotation and Assembly

Genome Annotation and Assembly

The genome refers to all of the genetic material in an organism. It can range from a few million base pairs in microbial cells to several billion base pairs in many eukaryotic organisms. Genome assembly refers to the process of taking the DNA sequencing data and putting it all back together in a correct order to create a close representation of the original genome. This is followed by the identification of functional elements on the newly assembled genome, a process called genome annotation.

Anatomical Terminology

Anatomical Terminology

Knowledge of anatomy is essential to understand human biology and medicine. Anatomists and health care professionals use standard terminology to describe the human body with more precision and no ambiguity. Anatomical terms have mostly Greek and Latin-derived roots. Because these languages are rarely used in conversation, the meaning of words remains the same. Each term is made up of a root in between the prefixes and suffixes. The root of a term often refers to an organ, tissue, or condition,...

Area of Science:

Biomedical Informatics
Data Integration
Knowledge Representation

Background:

Existing systems like ONTOFUSION excel at integrating structured biomedical data.
Integrating unstructured biomedical information remains a challenge due to the lack of logical schemas.

Purpose of the Study:

To develop a novel method for extracting logical schemas from unstructured biomedical text.
To enable the integration of unstructured biomedical data into existing structured frameworks.

Main Methods:

A new schema extraction technique was developed for text-based biomedical collections.
Extracted schemas allow unstructured data to be treated as structured data.
The ONTOFUSION system's integration tools were adapted for the combined data.

Main Results:

The novel method successfully extracts logical schemas from unstructured biomedical text.
This facilitated the integration of previously incompatible data sources.
An experiment with five cancer databases validated the approach's effectiveness.

Conclusions:

The proposed method effectively bridges the gap between structured and unstructured biomedical data.
This enhances the utility of systems like ONTOFUSION for comprehensive biomedical data integration.
The approach offers a scalable solution for managing diverse biomedical information sources.
