Summarization of Multimodal Information

چکیده
Information Summarization is one of the key challenges for current and future information systems. In this paper, we will outline a system that comprises modules for summarizing texts and time series to study the link between the two. Summaries of texts are generated using a lexical analysis of cohesion in texts focusing on key sentences that provide cohesion: by implication, these are the sentences that comprise chief points of a given text. Time series summarization is accomplished using the so-called wavelet analysis to separate out the trend, cyclical fluctuations and autocorrelational effects and generating verbal signals to describe each phenomenon. Finally, we present a case study performed on the UK financial market with regards to multimodal information processing, namely textual and numerical summarization.

Toward Extractive Summarization of Multimodal Documents
Summarization research has focused on text, and relatively little attention has been given to the summarization of multimodal documents. If extractive summarization techniques are to be used on multimodal documents containing information graphics (bar charts, line graphs, etc.), then a strategy must be devised both for extracting the high-level content of the information graphics and for identi...

متن کاملA survey on Automatic Text Summarization
Text summarization endeavors to produce a summary version of a text, while maintaining the original ideas. The textual content on the web, in particular, is growing at an exponential rate. The ability to decipher through such massive amount of data, in order to extract the useful information, is a major undertaking and requires an automatic mechanism to aid with the extant repository of informa...
متن کاملExpansion of Multimodal Summarization for Trend Information -- Report on the first and second cycles of the MuST Workshop --
A trend, which is a general tendency in the way a situation is changing or developing, is based on temporal statistical data, and can be obtained by synthetically summarizing it. A system that can properly answer questions on interesting trends must help users to understand and review a huge amount of information. MuST, a workshop on multimodal summarization for trend information, was designed ...
متن کاملTowards a Framework for Abstractive Summarization of Multimodal Documents
We propose a framework for generating an abstractive summary from a semantic model of a multimodal document. We discuss the type of model required, the means by which it can be constructed, how the content of the model is rated and selected, and the method of realizing novel sentences for the summary. To this end, we introduce a metric called information density used for gauging the importance ...
