Investigating Text Shortening Strategy in BERT: Truncation vs Summarization

Q: How can other languages benefit from similar text shortening strategies?

Other languages can benefit from similar text shortening strategies by adapting the approach to suit their linguistic characteristics and specific datasets. By implementing extractive summarization techniques, languages with diverse structures and syntaxes can identify key information in a document efficiently. This method allows for the extraction of essential content while maintaining context, which is crucial for tasks like classification or sentiment analysis. Additionally, by exploring different variations of summarization and truncation methods tailored to each language's nuances, researchers can optimize performance in natural language processing tasks across various linguistic contexts.

Q: Does relying on extractive summarization limit creativity or originality in content?

Relying solely on extractive summarization may potentially limit creativity or originality in content due to its nature of selecting existing segments from the source material. Extractive summarization focuses on extracting important sentences verbatim from the input text without generating new phrases or restructuring information creatively. While this method ensures that critical details are preserved, it may overlook unique perspectives or innovative expressions present in the full document. As a result, there is a risk that some nuanced insights or creative elements could be lost when using extractive summarization exclusively.

Q: How can automated abstractive summarization be improved to enhance performance?

Automated abstractive summarization can be enhanced to improve performance through several approaches: Fine-tuning Models: Continuously fine-tuning pre-trained models on domain-specific data helps capture intricate patterns and generate more coherent summaries. Enhancing Language Understanding: Improving language understanding capabilities within models enables better comprehension of context and semantics for accurate abstraction. Incorporating Attention Mechanisms: Implementing attention mechanisms allows models to focus on relevant parts of the input during summary generation, enhancing coherence. Controlling Summary Length: Regulating summary length prevents excessive compression leading to loss of vital information while ensuring concise yet informative outputs. Utilizing Diverse Training Data: Training models on diverse datasets aids in capturing varied writing styles and vocabulary usage for robust performance across different texts. By integrating these strategies into automated abstractive summarization systems, researchers can elevate their effectiveness in producing high-quality summaries that maintain originality and convey essential content accurately.

Statistik

"The best strategy obtained in this study is taking the head of the document."
"The average number of tokens in a document is 346 tokens."
"Filtered IndoSum has around 13 thousand (13K) articles."

Citat

"This study concludes that extractive summaries as an alternative shortening strategy has great potential for a Transformer-based classification model."
"In general, whenever the location of the main idea of the document is unknown, taking the first part of the document seems to be the best assumption."
