บทคัดย่อ

The study evaluates the ability of (Chat)GPT and BERT to detect semantic changes over time using two diachronic extensions of the Word-in-Context task. While (Chat)GPT shows potential for long-term change detection, it struggles with short-term changes compared to BERT. The research raises questions about the effectiveness of language models in capturing semantic shifts accurately.

สถิติ

Can language models like (Chat)GPT be optimized for better performance in detecting short-term semantic changes?

In order to optimize language models like (Chat)GPT for better performance in detecting short-term semantic changes, researchers can consider several strategies. One approach is to fine-tune the model on specific datasets that focus on short-term semantic shifts, providing it with more targeted training data. This can help the model learn and adapt to the nuances of short-term changes in meaning.
Additionally, researchers can explore different prompting strategies that are tailored towards capturing short-term variations in language usage. By designing prompts that specifically highlight contextual cues indicative of rapid semantic shifts, the model can be guided to pay closer attention to these dynamics during inference.
Furthermore, incorporating mechanisms for continual learning and adaptation within the model architecture can enable it to dynamically update its understanding of evolving language patterns over time. This adaptive capability would allow the model to stay current with changing semantics and improve its performance in detecting short-term shifts.

How can researchers address the limitations of nondeterminism when evaluating models like ChatGPT?

Researchers can address the limitations of nondeterminism when evaluating models like ChatGPT by implementing rigorous experimental protocols and methodologies. One key strategy is conducting multiple runs of experiments with varying parameters such as temperature settings or prompt structures. By averaging results across multiple runs, researchers can mitigate the impact of randomness inherent in ChatGPT's responses.
Moreover, establishing clear evaluation criteria and metrics based on objective standards is essential for ensuring consistency and reliability in assessing model performance. Researchers should define specific benchmarks and validation procedures that account for variability introduced by nondeterministic outputs.
Another approach is leveraging ensemble methods where predictions from multiple instances or versions of ChatGPT are aggregated to reduce uncertainty and enhance overall prediction accuracy. Ensemble techniques help smooth out inconsistencies arising from individual instances' unpredictability.
Lastly, transparency regarding experimental setups, including detailed descriptions of input prompts used, parameter configurations applied, and any post-processing steps taken will aid in reproducibility efforts and facilitate a deeper understanding of how nondeterminism impacts evaluation outcomes.

What implications do these findings have for future research on semantic change detection beyond English language texts?

The findings presented regarding (Chat)GPT's performance in detecting semantic changes have significant implications for future research beyond English language texts:

Multilingual Semantic Change Detection: Researchers could extend similar evaluations to other languages using multilingual pre-trained models like mBERT or XLM-RoBERTa. Understanding how well these models capture cross-lingual lexical variations over time could enrich comparative studies across diverse linguistic contexts.

Cross-Cultural Semantic Shifts: Exploring how cultural factors influence semantic change detection could offer insights into how meanings evolve differently across various societies. Comparative analyses between languages may reveal universal patterns or unique cultural influences shaping lexical transformations.

Historical Text Analysis: Investigating diachronic corpora from different historical periods or regions could shed light on broader trends in linguistic evolution beyond contemporary English texts alone.

4 .Domain-Specific Semantic Evolution: Focusing on specialized domains such as medical terminology or legal jargon could uncover domain-specific lexical shifts over time—providing valuable insights into professional discourse evolution outside general language use cases.
By expanding research horizons beyond English-language datasets while considering diverse linguistic contexts and historical perspectives,
researchers stand poised to deepen our understanding
of semantic change dynamics globally across varied languages
and cultures through advanced AI technologies like (Chat) GPT
and BERT."
