With the increasing of online information and recourse texts , text summarization has become an essential and more favorite domain to preserve and show the main purpose of textual information . It is very difficult for human beings to summarize manually large documents of text . Multi-document summarization is also an integral tool for document understanding and well interpreting in the existing system of text summarization . But single text document summarization has been done from a single text document only . Text summarization can be done based on its input , purpose , and output . The hybrid model depends on the linear combination of statistical measures : sentence position , TF-IDF , Aggregate similarity , centroid , and semantic measure . Our idea to include sentiment analysis for salient sentence extraction is derived from the concept that emotion plays an important role in communication to effectively convey any message hence , it can play a vital role in text document summarization . For comparison we have generated five system summaries Proposed Work , MEAD system , Microsoft system , OPINOSIS system , and Human generated summary , and evaluation is done using ROUGE score . Opinion mining has been well studied for years , but very few have considered its application in spoken dialogue systems . Review summarization , when applied to real dialogue systems , is much more complicated than pure text-based summarization . We conduct a systematic study on dialogue-system-oriented review analysis and propose a three-level framework for a recommendation dialogue system . With the rapid increase in the size of the data over the internet there is a need for new studies for text data summarization and representation ; rather than storing the full text or reading the full text we can store and read a summary that represent the original text . Furthermore , there is a need also to represent the summarized text with visual representation ; one picture worth ten thousandwords . Recognizing textual entailment ( RTE ) is the task of determining whether two natural language sentences are ( i ) contradicting each other , ( ii ) not related , or whether ( iii ) the first sentence ( called premise ) entails the second sentence ( called hypothesis ) . This task is important since many natural language processing ( NLP ) problems , such as information extraction , relation extraction , text summarization or machine translation , rely on it explicitly or implicitly and could benefit from more accurate RTE systems [ reference ] . State - of - the - art systems for RTE so far relied heavily on engineered NLP pipelines , extensive manual creation of features , as well as various external resources and specialized subcomponents such as negation detection ( e.g. [ reference ][ reference ][ reference ][ reference ] . Despite the success of neural networks for paraphrase detection ( e.g. [ reference ][ reference ][ reference ] , end - to - end differentiable neural architectures failed to get close to acceptable performance for RTE due to the lack of large high - quality datasets . Knowledge graphs , such as WordNet , Freebase , and Google Knowledge Graph , are large graph - structured databases of facts , containing information in the form of triples , where and represent subject and object entities and a relationship between them . They are considered important information resources , used for a wide variety of tasks ranging from question answering to information retrieval , coreference resolution , and text summarization . One of the main challenges with existing knowledge graphs is their incompleteness : many of the links between entities in the graph are missing . document : Abstractive Text Summarization using Sequence - to - sequence RNNs and Beyond In this work , we model abstractive text summarization using Attentional Encoder - Decoder Recurrent Neural Networks , and show that they achieve state - of - the - art performance on two different corpora . section : Introduction Abstractive text summarization is the task of generating a headline or a short summary consisting of a few sentences that captures the salient ideas of an article or a passage . We use the adjective ‘ abstractive ’ to denote a summary that is not a mere selection of a few existing passages or sentences extracted from the source , but a compressed paraphrasing of the main contents of the document , potentially using vocabulary unseen in the source document . The MuST ( Multimodal Summarization for Trend Information ) workshop was designed to encourage cooperative and competitive studies on summarization and visualization for trend information . The main objective of the workshop is to develop technologies using multimedia presentation that will allow intelligent systems to provide users with appropriate answers to their queries on trend information . Multimodal text analysis has become a crucial part of research , teaching , and practice for a wide range of academic and practical disciplines . Keywords : culture ; discourse analysis ; language and social interaction ; research methods in applied linguistics ; grammar ; sociocultural language studies How , and to what extent , will multimodal discourse analysis re-shape linguistics ? In its attempt to provide answers to the questions raised above , and many others , this book proposes concrete solutions to the problems of multimodal text analysis and transcription of printed texts , websites and film . As such , it constitutes a much needed course in multimodal text transcription and analysis . A major challenge in this domain is usually the information overlap in documents emanating from various sources . This paper introduces an optimized semantic technique for multi-document abstractive summarization . Methods/Statistical Analysis : Linguistic and semantic approaches are usually employed for abstractive summarization of multiple documents . Multi-document abstractive summarization aims is to create a compact version of the source text and preserves the important information . The existing graph based methods rely on Bag of Words approach , which treats sentence as bag of words and relies on content similarity measure . This paper studies the abstractive multi-document summarization for event-oriented news texts through event information extraction and abstract representation . Fine-grained event mentions and semantic relations between them are extracted to build a unified and connected event semantic link network , an abstract representation of source texts . Abstract The lack of multi-document based models and the inaccuracy in representing multiple long documents into a fixed size vector inspired us to solve abstractive multi-document summarization . Also , there is lack of good multi-document based human-authored datasets to train any encoder-decoder models . We define an image collection summary as a subset of images from a collection , which is visually and semantically representative . To build such a summary we propose MICS ( Multimodal Image Collection Summarization ) , a method that combines textual and visual modalities in a common latent space , which allows to find a subset of images from which the whole collection can be reconstructed . Experiments were conducted on two collections of tagged images demonstrating the ability of the approach to build summaries with representative visual and semantic contents . Deep learning provides basic models for meeting this challenge . This paper treats extractive multi-modal summarization as a classification problem and proposes a sentence – image classification method based on the multi-modal RNN model . Our method encodes words and sentences with the hierarchical RNN models and encodes the ordered image set with the CNN model and the RNN model , and then calculates the selection probability of sentences and the sentence – image alignment probability through a logistic classifier taking text coverage , text redundancy , image set coverage , and image set redundancy as features . On a test set of 1 K annotated infographics , icons are located with 38 % precision and 34 % recall ( the best model trained with natural images achieves 14 % precision and 7 % recall ) . Combining our icon proposals with icon classification and text extraction , we present a multi-modal summarization application . Our application takes an infographic as input and automatically produces text tags and visual hashtags that are textually and visually representative of the infographic 's topics respectively . This work is used to enhance an accessibility system to an interactive natural language system in order to enable visually impaired users to gain access to the informational content of graphics that appear in popular media . The textual descriptions generated by this research can also be utilized in a variety of other natural language applications such as multimodal document summarizers and question answering systems . It is concerned with the recording and browsing of meetings using audio and video data . The M4 project proposes several innovations : multimodal localization and tracking of meeting focus , automatic multimodal emotion and intent recognition , gesture and action recognition , textual and multimodal summarization and a framework for integration of multimodal data . A meeting is a dynamic process which consists of group interactions between meeting participants . The main contributions of this study are that our model enables the following two abilities . paragraph : Multi - source abstractive summarization based RC . The first idea is to use a pointer - generator mechanism for multi - passage RC , which was originally proposed for text summarization section : Proposed Model Our proposed model , Masque , is based on multi - source abstractive summarization ; the answer our model generates can be viewed as a summary from the question and multiple passages . It is also style - controllable ; one model can generate the answer with the target style . Its primary goal is to generate summaries based on the cited paper itself . Previously , traditional scientific summarization focused on citation-based methods by aggregating all citances that cite one unique paper without doing content-based citation analysis , while sometimes citations might differ between researchers or time slots . By investigating original text spans where scholars cited , the new method can reflect exact contributions of reference papers more . Scientific summarization addresses this challenge by providing summaries of the important contributions of scientific papers . We present a framework for scientific summarization which takes advantage of the citations and the scientific discourse structure . Citation texts often lack the evidence and context to support the content of the cited paper and are even sometimes inaccurate . This overview describes the official results of the CL-SciSumm Shared Task 2018 -- the first medium-scale shared task on scientific document summarization in the computational linguistics ( CL ) domain . This year , the dataset comprised 60 annotated sets of citing and reference papers from the open access research papers in the CL domain . Scientific article summarization is challenging : large , annotated corpora are not available , and the summary should ideally include the article ’s impacts on research community . This paper provides novel solutions to these two challenges . ROUGE solely relies on lexical overlaps between the terms and phrases in the sentences ; therefore , in cases of terminology variations and paraphrasing , ROUGE is not as effective . Scientific article summarization is one such case that is different from general domain summarization ( e.g. newswire data ) . We provide an extensive analysis of ROUGE 's effectiveness as an evaluation metric for scientific summarization ; we show that , contrary to the common belief , ROUGE is not much reliable in evaluating scientific summaries . The combination of full text sentences and catchphrases from cited and citing cases is particularly successful . We also apply and evaluate the methods on scientific paper summarization , where they perform at the level of state-of-the-art techniques . Our family of citation-based summarization methods is powerful and flexible enough to target successfully a range of different domains and summarization tasks . Automatically summarizing scientific articles would help researchers in their investigation by speeding up the research process . The automatic summarization of scientific articles differs from the summarization of generic texts due to their specific structure and inclusion of citation sentences . Most of the valuable information in scientific articles is presented in tables , figures , and algorithm pseudocode . Automatic related work generation is a new challenge in multi-document scientific summarization focusing on refining a related work section for a given scientific paper . In this paper , we propose a brand new framework ToC-RWG for related work generation by incorporating topic model and citation information . Even though the pyramid method looks for important keyterms in the resulting summaries , it can not distinguish between a general introductory sentence about the area and a specific sentence on the core idea , if they both contain the same keyterm . Also , our results show that the state of the art summarization method LexRank is not feasible for scientific corpus summarization because of its high computational cost . intention of MapReduce Sets for Summarization expressions analysis has to suggest criteria how summarization expressions in summarization data can be defined in a meaningful way and how they should be compared . Similitude based MapReduce Sets for summarization Expression Analysis and MapReduce Sets for Assignment is expected to adhere to fundamental principles of the scientific summarization process that are expressiveness of summarization models and reproducibility of their summarization inference . Summarization expressions are assumed to be elements of a summarization expression space or Conjecture class and summarization data provide " information " which of these summarization expressions should be used to interpret the summarization data . In this paper we present experiments on scientific text summarization . From a complete text , we produce a shorter version containing all the main parts of the research . Extractive summarization , a process that automatically picks exemplary sentences from a text ( or spoken ) document with the goal of concisely conveying key information therein , has seen a surge of attention from scholars and practitioners recently . Using a language modeling ( LM ) approach for sentence selection has been proven effective for performing unsupervised extractive summarization . However , one of the major difficulties facing the LM approach is to model sentences and estimate their parameters more accurately for each text ( or spoken ) document . Coverage maximization with bigram concepts is a state-of-the-art approach to unsupervised extractive summarization . It has been argued that such concepts are adequate and , in contrast to more linguistic concepts such as named entities or syntactic dependencies , more robust , since they do not rely on automatic processing . We search for a high-scoring summary by discrete optimization . Our proposed method achieves a new state-of-the art for unsupervised sentence summarization according to ROUGE scores . Additionally , we demonstrate that the commonly reported ROUGE F1 metric is sensitive to summary length . We present several initial models which rely on the asymmetrical nature of the task to perform the first back-translation step , and demonstrate the value of combining the data created by these diverse initialization methods . Our system outperforms the current state-of-the-art for unsupervised sentence summarization from fully unaligned data by over 2 ROUGE , and matches the performance of recent semi-supervised approaches . Despite the advances in word embeddings ( i.e. word vector representations ) , capturing sentence meaning is an open question due to complexities of semantic interactions among words . In this paper , we present an embedding method , which is aimed at learning unsupervised sentence representations from unlabeled text . We propose an unsupervised method that models a sentence as a weighted series of word embeddings . We propose a method to learn unsupervised sentence representations in a non-compositional manner based on Generative Latent Optimization . Our approach does not impose any assumptions on how words are to be combined into a sentence representation . The paper describes an attempt to improve the TextRank algorithm . TextRank is an algorithm for unsupervised text summarisation . It has two main stages : first stage is representing a text as a weighted directed graph , where nodes stand for single sentences , and edges are weighted with sentence similarity and connect sequential sentences . The paper describes an attempt to improve the TextRank algorithm . TextRank is an algorithm for unsupervised text summarisation . It has two main stages : first stage is representing a text as a weighted directed graph , where nodes stand for single sentences , and edges are weighted with sentence similarity and connect consequent sentences . We employ a fully automated temporal processing system to generate a timeline for each input document . We derive three features from these timelines , and show that their use in supervised summarization lead to a significant 4.1 % improvement in ROUGE performance over a state-of-the-art baseline . In addition , we propose TIMEMMR , a modification to Maximal Marginal Relevance that promotes temporal diversity by way of computing time span similarity , and show its utility in summarizing certain document sets . We explore and compare token-level and dialogue act-level automatic summarization methods using both unsupervised and supervised learning frameworks . In the supervised summarization setting , and given true clusterings of decision-related utterances , we find that token-level summaries that employ discourse context can approach an upper bound for decision abstracts derived directly from dialogue acts . In the unsupervised summarization setting , we find that summaries based on unsupervised partitioning of decision-related utterances perform comparably to those based on partitions generated using supervised techniques ( 0.22 ROUGE-F1 using LDA-based topic models vs. 0.23 using SVMs ) . The algorithm explores candidate summaries space following an objective function computed over ngrams probability distributions of the candidate summary and the source documents . This method does not consider a summary as a stack of independent sentences but as a whole text , and makes use of advances in unsupervised summarization evaluation . We compare this sentence extraction method to one of the best existing methods which is based on integer linear programming , and show its efficiency on three different acknowledged corpora . document : Supervised Learning of Universal Sentence Representations from Natural Language Inference Data Many modern NLP systems rely on word embeddings , previously trained in an unsupervised manner on large corpora , as base features . paragraph : Finetuning Recent work has shown promising results using unsupervised language modeling , followed by transfer learning to natural language tasks , .
