High-Level and Low-Level Awareness01:19

High-Level and Low-Level Awareness

Controlled processes in human consciousness represent high-alert mental states where individuals deliberately focus their attention on achieving specific goals. Controlled processes can be seen in situations like mastering new technology, where a person might become so absorbed that they ignore surrounding distractions. Such processes involve selective attention, requiring one to concentrate on particular elements of experience while disregarding others. These are governed by executive...
Levels of Use of a GIS01:29

Levels of Use of a GIS

Geographic Information Systems (GIS) operate across three levels of application, each representing an increasing degree of complexity: data management, analysis, and prediction. These levels reflect the expanding functionality and versatility of GIS technology in handling spatial data for diverse purposes.Data ManagementAt its foundational level, GIS serves as a tool for data management, enabling the input, storage, retrieval, and organization of spatial data. This level is often employed in...

Levels of Organization

Biological organization is the classification of biological structures, ranging from atoms at the bottom of the hierarchy to the Earth's biosphere. Each level of the hierarchy represents an increase in complexity that builds upon the previous level.Molecules Are Composed of Atoms, and Biomolecules Are Assembled from Molecules:The most basic levels include atoms, molecules, and biomolecules. Atoms, the smallest unit of ordinary matter, are composed of a nucleus and electrons. Molecules comprise...

Collisions in Multiple Dimensions: Problem Solving

In multiple dimensions, the conservation of momentum applies in each direction independently. Hence, to solve collisions in multiple dimensions, we should write down the momentum conservation in each direction separately. To help understand collisions in multiple dimensions, consider an example.
A small car of mass 1,200 kg traveling east at 60 km/h collides at an intersection with a truck of mass 3,000 kg traveling due north at 40 km/h. The two vehicles are locked together. What is the...
Drug Discovery: Overview01:26

Drug Discovery: Overview

Drug discovery is a multifaceted process involving extensive screening, testing, and optimization of lead compounds to identify potential new drugs for therapeutic use. It combines several approaches, including screening large numbers of natural products, chemical modification of known active molecules, identification of new drug targets, and rational design based on biological mechanisms and drug-receptor structure. These approaches are carried out in both academic research laboratories and...
Models of Health Promotion and Illness Prevention I01:25

Models of Health Promotion and Illness Prevention I

A model is a theoretical way to understand a concept or an idea. Models can overcome barriers to health regardless of diverse economic and cultural backgrounds. In addition, models make the task easier by providing different ways to approach complex issues. There are two major health promotion models: the health belief model and the health promotion model.
The health belief model (HBM) attempts to predict health-related behavior in specific belief patterns. According to the HBM, a person's...

Area of Science:

  • Biomedical Informatics
  • Computational Biology
  • Knowledge Discovery

Background:

  • Previous methods for uncovering Undiscovered Public Knowledge (UPK) required significant manual effort and were limited to disease-effect relations.
  • Advancements in biomedical science necessitate automated methods for extracting and integrating information from diverse research to generate new hypotheses.

Purpose of the Study:

  • To develop an automated system for discovering implicit relationships within biomedical literature.
  • To extract and combine information across multiple research articles to infer new hypotheses and expand scientific knowledge.

Main Methods:

  • The Multi-level Knowledge Emergence Model (MKEM) utilizes Natural Language Processing (NLP) and ontologies like Unified Medical Language System (UMLS) MetaMap.
  • MKEM extracts implicit relationships across molecular (gene, protein) and phenomic (disease, treatment) levels.
  • Biological concepts are tagged using MetaMap, and a systematic approach is employed for relationship discovery.

Main Results:

  • The MKEM system was applied to 5000 PubMed abstracts.
  • Performance evaluation demonstrated good precision and recall, although a gold standard is not yet available.
  • The system successfully generated 24 novel hypotheses.

Conclusions:

  • MKEM is an effective tool for discovering hidden relationships among biological entities.
  • The Substance-Effect-Process-Disease-Body Part (SEPDB) model aids in representing extracted entities for knowledge discovery.
