We describe a technique for video summarization that uses motion descriptors computed in the compressed domain to speed up conventional color based video summarization technique. The basic hypothesis of the work is that the intensity of motion activity of a video segment is a direct indication of its “summarizability.” We present experimental verification of this hypothesis. We are thus able to...

The research below explores schemes for evaluating automatic summaries of business meetings, using the ICSI Meeting Corpus (Janin et al., 2003). Both automatic and subjective evaluations were carried out, with a central interest being whether or not the two types of evaluations correlate with each other. The evaluation metrics were used to compare and contrast differing approaches to automatic ...

In many application contexts, like statistical databases, scientific databases, query optimizers, OLAP, and so on, data are often summarized into synopses of aggregate values. Summarization has the great advantage of saving space, but querying aggregate data rather than the original ones introduces estimation errors which cannot be in general avoided, as summarization is a lossy compression. A ...

The development of summarization systems requires reliable similarity (evaluation) measures that compare system outputs with human references. A reliable measure should have correspondence with human judgements. However, the reliability of measures depends on the test collection in which the measure is meta-evaluated; for this reason, it has not yet been possible to reliably establish which are...

We present our work on open-domain multi-document summarization in the framework of Web search. Our system, SNS (pronounced “essence”), retrieves documents related to an unrestricted user query and summarizes a subset of them as selected by the user. We present a taskbased extrinsic evaluation of the quality of the produced multi-document summaries. The evaluation results show that summarizatio...

The Weibo-oriented Chinese news summarization task aims to automatically generate a short summary for a given Chinese news article, and the short summary is used for news release and propagation on Sina Weibo. The length of the short summary is less than 140 Chinese characters. The task can be considered a special case of single document summarization. In this paper, we will introduce the evalu...

We investigate the consistency of human assessors involved in summarization evaluation to understand its effect on system ranking and automatic evaluation techniques. Using Text Analysis Conference data, we measure annotator consistency based on human scoring of summaries for Responsiveness, Readability, and Pyramid scoring. We identify inconsistencies in the data and measure to what extent the...

In recent times, data is growing rapidly in every domain such as news, social media, banking, education, etc. Due to the excessiveness of data, there is a need of automatic summarizer which will be capable to summarize the data especially textual data in original document without losing any critical purposes. Text summarization is emerged as an important research area in recent past. In this re...
