For homogenous document collections, where it is reasonable to assume the prominence of a topic, multi-document summarization can be largely driven by this assumption. In any case, work on visualizing and navigating multi-document collections to date does not typically make provisions for, or use, multi-document summarization. The task of retrieving text spans is similar to the sentence selection task in automatic text summarization systems. Single-document summaries obtained in this way were concatenated and used as input in our tool for multi-document summarization. The second category of evaluation, an extrinsic evaluation, tests the summarization based on how it affects the completion of some other task. In the overview, the editors mention other new research areas that haven't featured in this collection such as multi-lingual information extraction and hybrid multi-document summarization. In the limit, question answering and summarization may merge as research areas. Efficiently computed lexical chains as an intermediate representation for automatic text summarization. Here the topic was not known to the summarization system. Intrinsic evaluation tests the summarization system in itself. Evaluating content selection in summarization: the pyramid method. Ideally, the tables of contents should be evaluated extrinsically in different tasks, among which the most important being information retrieval and text summarization. Providing appropriate coherent answers will be a major research area and will depend heavily on progress in text summarization. The dry-run indicated that we could expect very large effect sizes for the summarization condition and participant system tests. To address the issue in this paper, we take an intermediate approach between a fully structural model and pure data summarization. But a collection of input sentences doesn't constitute a natural class, so it doesn't lend itself to summarization to lighten the load. Coherence in itself is not a sufficient test of summarization capability; it is certainly possible to have a well-written but atrocious summary. Another challenge is designing evaluations which exploit features unique to summarization. Compared to approaches in text summarization, the key problem is determining what information in the source text should be included in the summary. The emphasis is on new research areas like multi-document summarization and multimedia summarization. In multi-document summarization, paraphrasing is important to avoid redundant statements in a summary. Another relevant area is the summarization of news articles. In the context of automatic text summarization, similar self-referencing statements can be formulated mathematically as the defining equations of a singular value problem. Further research is needed that will draw heavily on work in interactive retrieval, answer presentation and summarization, conversational interfaces and human-computer interaction in general. For each topic, 30 relevant documents from the ad hoc task corpus were chosen as the source texts for topic-related summarization. These examples are from corpora and from sources on the web.
