Relation Extraction (RE) is a multi-task process that is a crucial part of all information extraction pipelines. With the introduction of the generative language models, Large Language Models (LLMs) have showcased significant performance boosts for complex natural language processing and understanding tasks. Recent research in RE has also started incorporating these advanced machines in their pipelines. However, the full extent of the LLM’s potential for extracting relations remains unknown. Consequently, this study aims to conduct the first feasibility analysis to explore the viability of LLMs for RE by investigating their robustness to various complex RE scenarios stemming from data-specific characteristics. By conducting an exhaustive analysis of five state-of-the-art LLMs backed by more than 2100 experiments, this study posits that LLMs are not robust enough to tackle complex data characteristics for RE, and additional research efforts focusing on investigating their behaviors at extracting relationships are needed.

LLMs are increasingly applied for tasks requiring deep interpretive abilities and psychological insights, such as identity profiling, mental health diagnostics, personalized content curation, and human resource management. However, their performance in these tasks remains inconsistent, as these characteristics are not explicitly perceptible in the text. To address this challenge, this paper introduces a novel protocol called the “Psychological Text Extraction and Refinement Framework (PsyTEx)” that leverages LLMs to isolate and amplify psychologically informative segments and evaluate LLM proficiency in interpreting complex psychological constructs from text. Using personality recognition as a case study, our extensive evaluation of five SOTA LLMs across two personality models (Big Five and Dark Triad) and two assessment levels (detection and prediction) highlights significant limitations in LLM’s ability to accurately interpret psychological traits. However, our findings show that LLMs, when used within the PsyTEx protocol, can effectively extract relevant information that closely aligns with psychological expectations, offering a structured approach to support future advancements in modeling, taxonomy construction, and text-based psychological evaluations.

User-centric personalization of text opens many avenues of applications from stylized email composition to machine translation. Existing approaches in this domain often encounter limitations in data and resource requirements. Drawing inspiration from the success of resource-efficient prompt-enabled stylization in related fields, this work conducts the first feasibility into testing 12 pre-trained SOTA LLMs for author style emulation. Although promising, the results suggest that current off-the-shelf LLMs fall short of achieving effective author style emulation. This work provides valuable insights through which off-the-shelf LLMs could be potentially utilized for user-centric personalization easily and at scale.
