As part of our studies to discover new HIV‐1 reverse transcriptase inhibitors, a series of 3,4‐dichlorophenyl substituted 1,2,3‐thiadiazole thioacetanilide (TTA=[(1,2,3‐thiadiazole‐5‐yl)sulfanyl]acetanilide) derivatives were synthesized, and in vitro anti‐HIV activity was evaluated. The results revealed that nearly half of the compounds show moderate‐to‐good inhibitory potency against HIV‐1. In particular,...
We present a new approach to analyze Chinese questions based on a semantic knowledge base called conceptual network (ConNet). ConNet is composed of concepts, each of which describes the meaning of a Chinese word. Since there are no word boundaries in Chinese, we firstly segment each question into words, and then transform all the words into an ordered concept list. After that, an algorithm is proposed...
