Семантический дрейф

Bootstrapping has a tendency, called seman- tic drift, to select instances unrelated to the seed instances as the iteration proceeds. We demonstrate the semantic drift of bootstrap- ping has the …...

Multi-category bootstrapping algorithms were developed to reduce semantic drift. By ex- tracting multiple semantic lexicons simultane- ously, a category’s search space may be re- stricted. The best results have been …...

Iterative bootstrapping methods are widely employed for relation extraction, especially because they require only a small amount of human supervision. Unfortunately, a phenomenon known as semantic drift can affect the …...

AbstractNLP models often degrade in performance when real world data distributions differ markedly from training data. However, existing dataset drift metrics in NLP have generally not considered specific dimensions of …...
