Linguistic Boosting Factor. Type of extensions: XfDtShowKnn (closest by dssm-model, trained to predict XfDtShow extensions). Aggregation over all extensions. Largest weighted factor value. Normalized to the maximum weight of the extension. Stream: CorrectedCtrLongPeriod. Algorithm BclmPlaneProximity1Bm15W0Size1: uses bclm with weightless weighting if there are multiple query words, if there is one word then the match-weighted sum of hits is used. The normalization coefficient is 0.001.

description Фактор лингвистического бустинга. Тип расширений: XfDtShowKnn (ближайшие по dssm-модели, обучаемой предсказывать XfDtShow расширения). Агрегация по всем расширениям. Наибольшее взвешенное значение фактора. Нормировано на максимальный вес расширения. Стрим: CorrectedCtrLongPeriod. Алгоритм BclmPlaneProximity1Bm15W0Size1: использует bclm с безвесовым взвеживанием если слов запроса несколько, если слово одно, то используется взвешенная по типу совпадения сумма хитов. Коэффициент нормализации 0.001.
