Ta-G-T: Subjectivity Capture in Table to Text Generation via RDF Graphs
This work addresses the need for more interpretable and subjective text generation from tabular data, offering a structured approach that could benefit applications requiring nuanced data interpretation, though it appears incremental by building on existing T2T methods with a focus on subjectivity.
The paper tackles the problem of generating subjective text from tables, which is underexplored in Table-to-Text generation, by introducing a novel pipeline that uses RDF graphs to enhance factual accuracy and incorporate subjectivity, achieving performance comparable to GPT-3.5 and outperforming other models like Mistral-7B and Llama-2 in several metrics.
In Table-to-Text (T2T) generation, existing approaches predominantly focus on providing objective descriptions of tabular data. However, generating text that incorporates subjectivity, where subjectivity refers to interpretations beyond raw numerical data, remains underexplored. To address this, we introduce a novel pipeline that leverages intermediate representations to generate both objective and subjective text from tables. Our three-stage pipeline consists of: 1) extraction of Resource Description Framework (RDF) triples, 2) aggregation of text into coherent narratives, and 3) infusion of subjectivity to enrich the generated text. By incorporating RDFs, our approach enhances factual accuracy while maintaining interpretability. Unlike large language models (LLMs) such as GPT-3.5, Mistral-7B, and Llama-2, our pipeline employs smaller, fine-tuned T5 models while achieving comparable performance to GPT-3.5 and outperforming Mistral-7B and Llama-2 in several metrics. We evaluate our approach through quantitative and qualitative analyses, demonstrating its effectiveness in balancing factual accuracy with subjective interpretation. To the best of our knowledge, this is the first work to propose a structured pipeline for T2T generation that integrates intermediate representations to enhance both factual correctness and subjectivity.
