Error tolerant backbone resonance assignment is the cornerstone of the NMR structure determination process. Although a variety of assignment approaches have been developed, none works sufficiently well on noisy fully automatically picked peaks to enable the subsequent automatic structure determination steps. We have designed an integer linear programming(More)
A central task of computational linguistics is to decide if two pieces of texts have similar meanings. Ideally, this depends on an intuitive notion of semantic distance. While this semantic distance is most likely undefinable and un-computable, in practice it is approximated heuristically, consciously or unconsciously. In this paper, we present a theory,(More)
This paper describes a fault identification method based on the equivalence between the fault current drawn at an arbitrary point along a given line section and a pair of virtual superimposed current injections at the terminal nodes of the same line section. Therefore a fault can be located by estimating the pair of terminal current injections that would(More)
In this paper, we describe our submission to the NTCIR-12 Short Text Conversation task. We consider short text conversation as a community Question-Answering problem, hence we solve this task in three steps: First, we retrieve a set of candidate posts from a pre-built indexing service. Second, these candidate posts are ranked according to their similarity(More)
Error tolerant backbone resonance assignment is the cornerstone of the NMR structure determination process. Although a variety of assignment approaches have been developed, none works well on noisy automatically picked peaks. We have designed an integer linear programming (ILP) based assignment system (IPASS) for this purpose. In order to reduce size of the(More)
