abstractive text summarization using deep learning

The qualitative evaluation involved the manual evaluation of the proposed model. In the bidirectional decoder, there are two decoders: a forward decoder and a backward decoder. In addition, the RCT was evaluated using ROUGE1, ROUGE2, and ROUGE-L with values 37.27, 18.19, and 34.62 compared with the Gigaword dataset. The last hidden state of the forward decoder is fed as the initial input to the backward decoder, and vice versa. In the first model, the proposed model by Jobson et al., the word embedding, randomly initialised and updated during training, while GloVe word embedding was employed to represent the words in the second and third models [38]. Several variations in the Wang et al. While extractive models learn to only rank words and sentences, abstractive models learn to generate language as well. Experimental results on the datasets CNN and DailyMail show that our ATSDL framework outperforms the state-of-the-art models in terms of both semantics and syntactic structure, and achieves competitive results on manual linguistic quality evaluation. Abstractive Text Summarization (ATS), which is the task of constructing summary sentences by merging facts from different source sentences and condensing them into a shorter representation while preserving information content and overall meaning. Moreover, phrase extraction includes phrase combination, during which phrases with the same meaning are combined to minimise redundancy and the time required to train the LSTM-RNN. model were implemented. to perform text summarization. ROUGE-L is the longest common subsequence (LCS), which represents the maximum length of the common matching words between the reference summary and the generated summary. Two participants evaluated the summaries of 50 test examples that were selected randomly from the datasets. In all cases, the first input of the decoder is the token, and the same calculations are applied to compute the loss. For example, assume that the reference summary R and the automatic summary A are as follows: R: Ahmed ate the apple. Recent studies utilised the CNN/Daily Mail datasets for training and evaluation. Khandelwal [51] employed a sequence-to-sequence model that consists of an LSTM encoder and LSTM decoder for abstractive summarisation of small datasets. Deep learning analyses complex problems to facilitate the decision-making process. We proposed the use of the word embedding, which was built by considering the dependency parsing or part-of-speech tagging. Therefore, the output summary was balanced by considering both past and future information and by using a bidirectional attention mechanism. The proposed dual attention approach consists of three modules: two bidirectional GRU encoders and one dual attention decoder. T. Shi, Y. Keneshloo, N. Ramakrishnan, and C. K. Reddy, A. Joshi, E.

A bidirectional decoder with a sequence-to-sequence architecture, which is referred to as BiSum, was employed to minimise error accumulation during testing [62]. Lopyrev [29] proposed a simplified attention mechanism that was utilised in an encoder-decoder RNN to generate headlines for news articles. This paper proposes a text summarization approach for fac- tual reports using a deep learning model. Dima Suleiman, Arafat Awajan, "Deep Learning Based Abstractive Text Summarization: Approaches, Datasets, Evaluation Measures, and Challenges", Mathematical Problems in Engineering, vol. The proposed approach considered past and future context on the decoder side when making a prediction as it employed a bidirectional RNN. In the QRNN, the GRU was utilised in addition to the attention mechanism. to perform text summarization. BERT creates a single large transformer by combining the representations of the words and sentences. Text Summarization is the task of condensing long text into just a handful of sentences. The forward decoder considers a reference from the backward decoder. Few-Shot Learning for Abstractive Multi-Document Opinion Summarization. Nine research papers utilised Gigaword, fourteen papers employed the CNN/Daily Mail datasets (largest number of papers on the list), and one study applied the ACL Anthology Reference, DUC2002, DUC2004, New York Times Annotated Corpus (NYT), and XSum datasets. The most common challenges faced during the summarisation process were the unavailability of a golden token at testing time, the presence of OOV words, summary sentence repetition, sentence inaccuracy, and the presence of fake facts. The encoder reads the input words and their representations. Electron Commer Res 18(1):109–124. Figure 17 displays the number of surveyed papers that applied each of the datasets. However, our approach will be the second type, called Abstractive Summarization. Immediate online access to all issues from 2019. Moreover, the decoder utilised copying and coverage mechanisms. Furthermore, to obtain several vectors for a phrase, multiple kernels with different widths that represent the dimensionality of the features were utilised. in 2015, where a local attention-based model was utilised to generate summary words by conditioning it to input sentences [18]. 92,000 text sources and 219,000 text sources and 219,000 text sources, including Gigaword CNN/Daily.
