User generated content on Twitter (produced at an enormous rate of 340 million tweets per day) provides a rich source for gleaning people's emotions, which is necessary deeper understanding behaviors and actions. Extant studies emotion identification lack comprehensive coverage "emotional situations" because they use relatively small training datasets. To overcome this bottleneck, we have automatically created large emotion-labeled dataset (of about 2.5 tweets) by harnessing emotion-related...

The problem of automatic extraction sentiment expressions from informal text, as in microblogs such tweets is a recent area investigation. Compared to formal product reviews or news articles, one the key challenges lies wide diversity and nature that cannot be trivially enumerated captured using predefined lexical patterns. In this work, we present an optimization-based approach automatically extract for given target (e.g., movie, person) corpus unlabeled tweets. Specifically, make three...

This paper presents our solution for the i2b2 sentiment classification challenge. Our hybrid system consists of machine learning and rule-based classifiers. For classifier, we investigate a variety lexical, syntactic knowledge-based features, show how much these features contribute to performance classifier through experiments. propose an algorithm automatically extract effective lexical patterns from training examples. The experimental results that outperforms baseline using unigram...

The information measurement of the NAR (network access requester) is key element for trusted network access. only issues TNC (trusted connection) proposed conception integrity and pointed out that if measurements passed can NAS ((network server) let endpoint enter. But no concrete techniques are expatiated in TNC, related specification IMM (integrity model) too complex to implement. Virtually, cannot be localized integrity. In this paper, a new architecture proposed, which not platform, but...
