The average length of the queries is 3.2 words, and the average length of the documents is 1,323.3 ....

....by how well they perform on certain (extrinsic tasks [23] indicating document relevance to a topic, indicating a category for the document or intrinsic tasks whether they contain answers to specific questions. Summaries can also be evaluated by whether they extract the relevant portions of text [13,28] (intrinsic) which is the focus of my research. 2.2 Multi Document In the past few years, multi document summarization has become a subject of great interest due to the rapid increase in textual information, which has made it virtually impossible for users to browse or read many individual ....
....such as who and where, linguistic features such as name and place could be boosted in the weighting. CMU and GE used these features for the Q A section of the TIPSTER formal evaluation with some success [39] Other linguistic features include quotations, honorifics, and thematic phrases [28]. Furthermore, different document genres can be assigned weights to reflect their individual linguistic features, a method used by GE [36] For example, it is a well known fact that summaries of newswire stories usually include the first sentence of the article (see Table 1) Accordingly, this ....

....problem through the seventies and eighties (e.g. 19, 26] The resources devoted to addressing this problem grew by several orders of magnitude with the advent of the worldwide web and large scale search engines. Several innovative approaches began to be explored: linguistic approaches (e.g. [2, 3, 6, 12, 15, 16, 18, 20]) statistical and informationcentric approaches (e.g. 8, 9, 17, 25] and combinations of the two (e.g. 5, 25] Almost all of this work (with the exception of [12,16,20,24] focused on summarization by text span extraction , with sentences as the most common type of text span. This ....
