23 Oct 2016TL;DR: The amount of redundancy in a document collection can be used for assigning importance to sentences in multi-document extractive summarization and an unsupervised graph-based technique is proposed that allows for experiment with intra-document and inter-document redundancy.
Abstract: Multi-document summarization differs from single-document summarization in excessive redundancy of mentions of some events or ideas. We show how the amount of redundancy in a document collection can be used for assigning importance to sentences in multi-document extractive summarization: for instance, an idea could be important if it is redundant across documents because of its popularity; on the other hand, an idea could be important if it is not redundant across documents because of its novelty. We propose an unsupervised graph-based technique that, based on proper similarity measures, allows us to experiment with intra-document and inter-document redundancy. Our experiments on DUC corpora show promising results.

26 Apr 2004TL;DR: This article discusses a technique of generating hierarchical topic trees of a text and to use them in various ways to build summaries of a flexible length and compares the results when the topic tree is used for automatic summarization.
Abstract: Summarizing document texts at various levels of detail is required for many information selection tasks For instance, when loading and visualizing documents on small screens of handheld devices, it is important to be able to dynamically compress texts In this article we discuss a technique of generating hierarchical topic trees of a text and to use them in various ways to build summaries of a flexible length For the topic tree building process we have implemented both a deterministic and probabilistic approach We compare the results when the topic tree is used for automatic summarization

TL;DR: An approach for summarization from multiple documents which report on events that evolve through time, taking into account the different document sources, is presented, distinguish the evolution of an event into linear and non-linear.
Abstract: Panagiotis Stamatopoulos Department of Informatics, University of Athens, Greece takis@di.uoa.gr Abstract We present an approach for summarization from multiple documents which report on events that evolve through time, taking into account the different document sources. We distinguish the evolution of an event into linear and non-linear. According to our approach, each document is represented by a collection of messages which are then used in order to instantiate the cross-document relations that determine the summary content. The paper presents the summarization system that implements this approach through a case study on linear evolution.

20 Jun 2011TL;DR: This paper proposes an ontology enhanced multimedia summarization environment able to derive a synthetic representation of audio/video contents by a limited loss of meaningful information while overcoming the information overload problem.
Abstract: The growing amount of multimedia data acquired during courtroom debates makes information and knowledge management in judicial domain a real challenge. In this paper we tackle the problem of summarizing this large amount of multimedia data in order to support fast navigation of the streams, efficient access to the information and effective representation of relevant contents needed during the judicial process. In particular, we propose an ontology enhanced multimedia summarization environment able to derive a synthetic representation of audio/video contents by a limited loss of meaningful information while overcoming the information overload problem.
