Leveraging Natural Language Processing to Automate the Analysis of Public Perceptions and Discourse around Biodiversity from Digital Media

Core Concepts

This study introduces a novel pipeline that leverages modern natural language processing techniques to efficiently retrieve, filter, and analyze online news articles and social media posts related to biodiversity, enabling comprehensive monitoring of public perceptions and discourse around different animal taxa.

Abstract

The study presents a comprehensive pipeline for monitoring public discourse on biodiversity using online news and social media data. Key aspects of the pipeline include:

Constructing a "folk taxonomy" to identify common names used by the public to refer to different animal taxa, overcoming the limitations of using only scientific or full common names.
Retrieving relevant news articles and social media posts using keyword searches based on the folk taxonomy, while incorporating negative keywords to improve search specificity.
Employing zero-shot text classification with large language models to efficiently filter out irrelevant content, avoiding the need for manual data annotation.
Deduplicating syndicated news articles and extracting sentences directly mentioning the target taxa to enable focused analyses.

The pipeline is illustrated through a case study examining public discourse around various mammal taxa, including bats, pangolins, elephants, and gorillas, before and during the COVID-19 pandemic. Key findings include:

Significant geographic variations in media coverage, with globally recognized taxa like gorillas receiving widespread attention, while lesser-known taxa like pangolins and pipistrelle bats see more concentrated coverage.
Differences in the distribution of topics associated with news media coverage of different taxa, with horseshoe bats exhibiting more discourse on health, food, and socioeconomic issues compared to long-tongued bats.
A significant increase in the volume of news articles about horseshoe bats at the onset of the COVID-19 pandemic, accompanied by a shift toward more positive sentiment in both news and social media discourse.
The authors argue that this automated approach to monitoring public perceptions of biodiversity can provide crucial insights to support conservation efforts and track progress toward global biodiversity targets.

Stats

Up to 62% of articles mentioning "bats" were deemed irrelevant to biodiversity, highlighting the importance of relevance filtering.
The volume of news articles about horseshoe bats increased significantly at the onset of the COVID-19 pandemic.
There was a significant positive shift in sentiment toward horseshoe bats in both news media and social media discourse in late 2020.

Deeper Inquiries

How can the proposed pipeline be extended to incorporate data sources in languages other than English to provide a more comprehensive global perspective on public discourse around biodiversity?

Expanding the proposed pipeline to include data sources in languages other than English is crucial for capturing a more diverse and comprehensive global perspective on public discourse around biodiversity. To achieve this, several key steps can be taken:

Language Translation: Implementing language translation capabilities within the pipeline can help convert non-English content into English for analysis. Utilizing machine translation tools like Google Translate or custom language models can facilitate this process.

Multilingual NLP Models: Integrating multilingual Natural Language Processing (NLP) models such as mBERT (multilingual BERT) or XLM-R (Cross-lingual Language Model) can enable the pipeline to process and analyze text data in multiple languages simultaneously.

Language-specific Search Terms: Developing language-specific search terms and folk taxonomies for different languages can enhance the accuracy and relevance of data retrieval from non-English sources.

Collaboration with Linguistic Experts: Collaborating with linguistic experts or native speakers of different languages can provide valuable insights into cultural nuances, idiomatic expressions, and common terms used in local contexts, ensuring the pipeline's effectiveness across diverse linguistic landscapes.

Data Source Diversification: Expanding the range of data sources to include social media platforms, news outlets, and online forums in various languages can enrich the dataset and offer a more holistic view of public attitudes towards biodiversity on a global scale.

By incorporating these strategies, the pipeline can effectively capture and analyze public discourse in multiple languages, offering a more inclusive and nuanced understanding of biodiversity perceptions worldwide.

What are the potential limitations and biases introduced by relying on digital media data, and how can they be addressed to ensure the reliability of insights derived from this approach?

While digital media data provides valuable insights into public attitudes towards biodiversity, several limitations and biases can impact the reliability of the derived insights. Some key considerations include:

Selection Bias: Digital media data may not represent the entire population, as certain demographics or regions may be overrepresented or underrepresented in online discussions. This can lead to biases in the analysis results.

Content Quality: The quality and accuracy of information shared on digital platforms vary, and misinformation or sensationalized content can skew perceptions and sentiments related to biodiversity.

Language and Cultural Biases: Language nuances, cultural differences, and context-specific interpretations can introduce biases in sentiment analysis and topic categorization, especially when analyzing data from diverse linguistic backgrounds.

Algorithmic Biases: Machine learning algorithms used for data processing and analysis may exhibit biases based on the training data, leading to skewed results or misinterpretations of public discourse.

To address these limitations and biases and ensure the reliability of insights derived from digital media data, the following strategies can be implemented:

Diverse Data Sources: Incorporate data from multiple platforms and sources to mitigate selection bias and provide a more comprehensive view of public perceptions.

Validation and Verification: Implement fact-checking mechanisms and validation processes to verify the accuracy of information extracted from digital media sources.

Human Oversight: Combine automated analysis with human oversight to interpret nuanced content, identify biases, and ensure the validity of insights derived from the data.

Continuous Monitoring: Regularly assess and recalibrate the analysis methods to adapt to evolving digital trends, platform changes, and emerging biases in online discourse.

By implementing these strategies, researchers can enhance the reliability and robustness of insights derived from digital media data, enabling more accurate assessments of public attitudes towards biodiversity.

Given the dynamic nature of online platforms and the evolving landscape of digital data accessibility, how can conservation practitioners and researchers adapt their monitoring approaches to remain agile and responsive to these changes?

To adapt to the dynamic nature of online platforms and evolving digital data accessibility, conservation practitioners and researchers can employ the following strategies to ensure their monitoring approaches remain agile and responsive:
