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)
