Statistical and Similarity Methods for Classifying Emotion in Suicide Notes
In this paper we report on the approaches that we developed for the 2011 i2b2 Shared Task on Sentiment Analysis of Suicide Notes. We have cast the problem of detecting emotions in suicide notes as a supervised multi-label classification problem. Our classifiers use a variety of features based on (a) lexical indicators, (b) topic scores, and (c) similarity measures. Our best submission has a pre...
متن کاملA Naïve Bayes Approach to Classifying Topics in Suicide Notes
The authors present a system developed for the 2011 i2b2 Challenge on Sentiment Classification, whose aim was to automatically classify sentences in suicide notes using a scheme of 15 topics, mostly emotions. The system combines machine learning with a rule-based methodology. The features used to represent a problem were based on lexico-semantic properties of individual words in addition to reg...
متن کاملClassifying pentavalnet symmetric graphs of order $24p$
A graph is said to be symmetric if its automorphism group is transitive on its arcs. A complete classification is given of pentavalent symmetric graphs of order 24p for each prime p. It is shown that a connected pentavalent symmetric graph of order 24p exists if and only if p=2, 3, 5, 11 or 17, and up to isomorphism, there are only eleven such graphs.
متن کاملSuicide and attempted suicide
Accurate prediction of suicide risk remains a challenge, in its prevention. Many people with psychiatric disorders do not manifest suicidal behaviour, suggesting the importance of diathesis, or susceptibility to suicide, in addition to associated disorders. At present there are no biomarkers to predict suicidal behaviour. The authors of this article have attempted to describe the neurobiology o...
