A photonic-nose for the detection and discrimination of volatile organic compounds (VOCs) was constructed. Each sensing element on the photonic sensor array was formed by infiltrating a specific type of ionic liquid (IL) into the pore channel of a patterned porous silicon (PSi) chip. Upon exposure to VOC, the density of IL dramatically decreased due to the nano-confinement effect. As a result, the...
Sentiment bag of words plays an important role in sentiment analysis. In the paper we propose a method to construct an AMBIGUOUS SENTIMENT CONFINED LIBRARY without hard work. Followed by preprocessing and extracting features based on our AMBIGUOUS SENTIMENT CONFINED LIBRARY Maximum Entropy classifier is trained by our selected corpus and used to classify Chinese review sentiment. Comparing with extracting...
