Алгоритм реферирование текста_2 ® Утёмов В.В.
2008г.
Алгоритм симметрического реферирования
Симметричное реферирование основано на установлении весов (количества связей между предложениями). При первом проходе устанавливаются связи с правой стороны, при втором – с левой. Можно принимать во внимание только левосторонние связи, то есть связи с предшествующим текстом, не учитывая правосторонние связи, но в этом случае нарушается принцип симметричности, и реферирование становится асимметричным.
Цель: с помощью алгоритма симметрического реферирования получить реферат (выбор текста осуществляется в соответствии с предыдущим вариантом реферирования. см. приложение№2)
Пример
Исходный текст (Microsoft Corp. Introducing Windows NT. http://www.mcp.com/846201600/0-672/0-672-30933-5/ch01.htm)
