Non-equilibrium in the Cell

Non-equilibrium in the Cell

An important concept in studying metabolism and energy is that of chemical equilibrium. Most chemical reactions are reversible. They can proceed in both directions, releasing energy into their environment in one direction, and absorbing it from the environment in the other direction. The same is true for the chemical reactions involved in cell metabolism, such as the breaking down and building up of proteins into and from individual amino acids, respectively. Reactants within a closed system...

Automatic Processing and Automatic Social Behavior

Automatic Processing and Automatic Social Behavior

Automatic processing refers to the cognitive operations that occur without conscious intent or awareness, playing a fundamental role in shaping social cognition and behavior. These processes enable individuals to navigate complex social environments efficiently by relying on mental shortcuts and pre-existing knowledge structures known as schemas. One of the most influential mechanisms underlying automatic processing is priming, which subtly activates mental representations through exposure to...

Area of Science:

Bibliometrics
Information Science
Computational Linguistics

Background:

Systematic reviews require extensive title-abstract screening, a laborious process.
Natural language processing (NLP) and machine learning (ML) offer potential for automating this task.
Practical guidance for implementing NLP and ML in screening is highly needed.

Purpose of the Study:

To present a comprehensive pipeline for utilizing NLP and ML in title-abstract screening.
To provide practical guidance for applying these computational techniques in systematic reviews.

Main Methods:

Developing an NLP pipeline to prepare titles and abstracts for ML algorithms.
Applying ML algorithms to predict the relevance of publications for full-text screening.
Demonstrating the methodology with two real-world systematic reviews.

Main Results:

The proposed NLP and ML pipeline effectively predicts publications for full-text screening.
The approach shows promising performance in real-world systematic review scenarios.
The methodology offers a viable solution for semi-automating title-abstract screening.

Conclusions:

NLP and ML can significantly aid in semi-automating title-abstract screening for systematic reviews.
Successful implementation requires careful consideration of project-specific factors.
This approach can enhance the efficiency of systematic review preparation.
