Evaluating Transformer-Based Models for Abstractive Text Summarization Across Multiple Datasets with Hallucination Analysis Smriti Singh, Anil Kumar Singh Proceedings of 2025 International Conference on Signal Processing Computation Electronics Power and Telecommunication Iconscept 2025, 2025 Abstractive text summarization refers to creating a concise version of a document that conveys its main ideas in the form of a summary or headline. With the increasing performance of pre-trained transformer models, summarization has become an essential task in natural language processing. In this study, we present a comparative evaluation of four state-of-the-art transformer-based models T5, BART, PEGASUS, and Flan-T5 on three widely used datasets, namely CNN/DailyMail, XSum, and Gigaword. The evaluation of the models has been carried out using standard ROUGE metrics (ROUGE-1, ROUGE-2, ROUGE-L and ROUGE-Lsum) to assess informativeness and linguistic quality. In addition, we incorporated FactCC and SummaC metrics to measure factual consistency and estimate the hallucination rate in generated summaries. The experimental results reveal that model performance varies between datasets, highlighting the dataset-specific strengths of different architectures. For the CNN/DailyMail dataset, BART performs best with a ROUGE-1 score of 0.425, while PEGASUS performs well on the XSum dataset with a ROUGE-1 score of 0.386, where Flan-T5 consistently demonstrates competitive performance, surpassing the other models on the Gigaword dataset with a ROUGE-1 score of 0.348. However, factuality analysis shows that higher ROUGE scores do not mean lower hallucination rates. Models with strong lexical overlap sometimes produce factually inconsistent summaries. This study emphasizes the importance of combining traditional informativeness metrics with hallucination-aware evaluations to obtain a more reliable and comprehensive understanding of summarization model performance.
Recent trends in the detection of staphylococcal enterotoxins in the food matrix Biosensing Methods Applications and Technology, 2023
Virtual screening of truncated single stranded DNA aptamers for Staphylococcal enterotoxin type A Smriti Singh, Papia Chowdhury, Arabinda Ghosh, Seema Nara Journal of Biomolecular Structure and Dynamics, 2023 Single stranded DNA (ssDNA)/RNA aptamers, are screened through the labor intensive, iterative Systematic Evolution of Ligand by Exponential Enrichment process (SELEX) method. Complete sequence of screened aptamers never interacts with target or participates in final structure. Hence, in silico tools can be used to redesign a short length aptamer from previously reported aptamers which can have high affinity and specificity to the target. This approach is fast, cost effective, and less laborious than in vitro SELEX towards finding an aptamer sequence with better affinity with the target. Here, Staphylococcal enterotoxin type A (SEA) was used as target. A total of nine aptamers reported for different Staphylococcal food poisoning (SFP) enterotoxins were used as a starting pool. The aptamers were variously truncations and thoroughly analyzed through in silico methods. Three truncated aptamers namely AptSEA1.4, AptSEA2.4 and AptSEA8.4 were found to show higher affinity with target SEA. The computational data was also validated with DOT BLOT assay complemented with image analysis. These results also confirmed that the % specific binding and the dissociation constant (Kd) of truncated aptamers AptSEA1.4, AptSEA2.4 and AptSEA8.4 was better than their original counterparts. The truncated aptamers showed great promise to be used as a capture reagent in developing a sensitive assay for detection of SEA. Communicated by Ramaswamy H. Sarma
