Factor on filtered original query: dssm-distance from query without words to original query is calculated, then cutoff by threshold. Weighted stream aggregation Url,Title,Body,Links,CorrectedCtr,LongClick,OneClick,BrowserPageRank,SplitDwellTime,SamplePeriodDayFrc,SimpleClick,YabarVisits,YabarTime. Word weights aggregation algorithm: Bm15FLog (Bm15 aggregation of word occurrence logarithms). The normalization coefficient is 0.001.

description Фактор по фильтрованному оригинальному запросу: вычисляется dssm-расстояние от запроса без слов до исходного запроса, после чего происходит отсечение по порогу. Взвешенное объединение стримов Url,Title,Body,Links,CorrectedCtr,LongClick,OneClick,BrowserPageRank,SplitDwellTime,SamplePeriodDayFrc,SimpleClick,YabarVisits,YabarTime. Алгоритм агрегации весов слов: Bm15FLog (Bm15 агрегация логарифмов встречаемости слов). Коэффициент нормализации 0.001.
