Exploring Negation Annotations in the DrugDDI Corpus
Detecting drug-drug interactions (DDI) is an important research field in pharmacology and medicine and several publications report every year the negative effect of combining drugs and chemical treatments. The DrugDDI corpus is a collection of documents derived from the DrugBank database and contains manual annotations for interactions between drugs. We have investigated the negated statements ...
متن کاملNegation Without Negation in Probabilistic Logic Programming
Probabilistic logic programs without negation can have cycles (with a preference for false), but cannot represent all conditional distributions. Probabilistic logic programs with negation can represent arbitrary conditional probabilities, but with cycles they create logical inconsistencies. We show how allowing negative noise probabilities allows us to represent arbitrary conditional probabilit...
متن کاملExploring Surface-Level Heuristics for Negation and Speculation Discovery in Clinical Texts
We investigate the automatic identification of negated and speculative statements in biomedical texts, focusing on the clinical domain. Our goal is to evaluate the performance of simple, Regex-based algorithms that have the advantage of low computational cost, simple implementation, and do not rely on the accurate computation of deep linguistic features of idiosyncratic clinical texts. The perf...
متن کاملStable Ilp : Exploring the Added Expressivity of Negation in the Background Knowledge
We present stable ILP, a cross-disciplinary concept straddling machine learning and nonmonotonic reasoning. Stable models give meaning to logic programs containing negative assertions. In stable ILP, we employ stable models to represent the current state speciied by (possibly) negative EDB and IDB rules. The state then serves as the background knowledge for a top-down ILP learner. We present a ...
متن کاملNegation and Double-Negation of Chinese Oppositeness
Oppositeness refers to the paradigmatic relationship of two words holding the contrast meanings. The fact that linguistic opposite differs from logical contrast has been discussed in theories, but has not been tested in practice. In this paper, we investigate three main subtypes of Chinese oppositeness, via using logical tests of negation and double-negation. Result shows that purely logical te...
