值得一提的是,所有baseline都利用了attention机制,ATAE-LSTM还通过将方面连接到上下文单词的每个单词嵌入中来对上下文和方面建模。相反,AA-LSTM只对上下文建模,不进行任何其他处理。这证明了AA-LSTM的上下文建模结果是面向aspect的。这是因为方面信息在建模过程中用于控制信息流、保留和过滤信息,而这些信息作为早期的attenti...

But the attention mechanism used in them does not take the distance into account when calculating the weight of words and ignores the important influence of their neighboring words. To solve this problem, we introduce an A spect and O pinion Terms Co- E xtraction model, AOExtractor, that ...
Recently, wireless sensor networks (WSNs) have received considerable attention due to their applicability to reconnaissance, surveillance, security, and environmental monitoring [1,2]. A typical WSN consists of a large number of low-cost battery-powered devices and usually has very stringent energy an...
