Summary
This study introduces an automated method to analyze implicit media frames, revealing how public understanding of science evolves. Analyzing semantic changes in newspaper debates helps detect emerging metaphors and track trends.
Area of Science:
- Science communication
- Media studies
- Computational linguistics
Background:
- Mass media framing significantly influences public perception of science and technology.
- Analyzing media frames over time is crucial for understanding science communication dynamics.
- Distinguishing between implicit and explicit media frames offers deeper insights.
Purpose of the Study:
- To introduce an automated method for analyzing implicit media frames.
- To investigate the evolution of media frames in public debates on science and technology.
- To explore the relationship between public discourse and scientific meaning.
Main Methods:
- Developed an automated method for implicit media frame analysis.
- Applied a semantic maps method to a case study.
- Analyzed newspaper debates on artificial sweeteners in the New York Times (1980-2006).
Main Results:
- Automated analysis of semantic changes effectively filters implicit frame dynamics.
- Detected emerging metaphors within public debates on artificial sweeteners.
- Demonstrated the utility of semantic analysis for tracking frame evolution.
Conclusions:
- Implicit media frames and their changes can be automatically analyzed.
- Semantic analysis reveals shifts in public understanding and metaphorical language.
- This approach offers new avenues for studying public discourse and scientific trends.

03:26Framing Effects
Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in different ways based on the...
01:10Sugars as Energy Storage Molecules
Sugar (a simple carbohydrate) metabolism (chemical reactions) is a classic example of the many cellular processes that use and produce energy. Living things consume sugar as a major energy source because sugar molecules have considerable energy stored within their bonds. Consumed carbohydrates have their origins in photosynthesizing organisms like plants. During photosynthesis, plants use the energy of sunlight to convert carbon dioxide gas into sugar molecules, like glucose. Because this...
02:16Self-Schemas
In general, 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.
