Organochlorine pesticides are chlorinated hydrocarbon compounds.The production and use of organochlorine pesticides have been restricted around the world because they are persistent and toxic and able to undergo long-...
为有效解决构建电力运检知识图谱的关键步骤之一的电力运检命名实体识别问题,通过构建一种基于Stacking多模型融合的隐马尔可夫-条件随机场-双向长短期记忆网络(hidden Markov-conditional random fields-bi-directional long short-ter...
In spite of remote location and very limited human activities,Antarctica is affected by persistent organic pollutants(POPs).POPs investigation in Antarctica has a comparatively long history,but there are still large k...
