41. There are broadly two types of extractive summarization tasks depending on what the summarization program focuses on. 42. LexRank is an algorithm essentially identical to TextRank, and both use this approach for document summarization . 43. While submodular functions are fitting problems for summarization , they also admit very efficient algorithms for optimization. 44. Most summarization systems perform an extractive approach, selecting and copying important sentences from the source documents. 45. According to the Affycomp benchmark FARMS outperformed all other summarizations methods with respect to sensitivity and specificity. 46. The technique allows summarization to reduce the number of forwarding table entries within the carrier network switches. 47. Also in biotechnology, he developed " Factor Analysis for Robust Microarray Summarization " ( FARMS ). 48. It could perform archiving automatically, and maybe even allow for summarizations of threads to be inserted. 49. Similarly, in image summarization the system finds the most representative and important ( or salient ) images. 50. Video summarization is a related domain, where the system automatically creates a trailer of a long video.
