In this paper, we describe the event nugget annotation created in support of the pilot Event Nugget Detection evaluation in 2014 and in support of the Event Nugget Detection and Coreference open evaluation in 2015, which was one of the Knowledge Base Population tracks within the NIST Text Analysis Conference. We present the data volume annotated for both training and evaluation data for the 201...

A tight criterion under which the abstract version Lovász Local Lemma (abstract-LLL) holds was given by Shearer [43] decades ago. However, little is known about that of the variable version LLL (variable-LLL) where events are generated by independent random variables, though this model of events is applicable to almost all applications of LLL. We introduce a necessary and sufficient criterion f...

Hydrogen bonding has a ubiquitous role in electron transport and in molecular recognition, with DNA base pairing being the best-known example. Scanning tunnelling microscope images and measurements of the decay of tunnel current as a molecular junction is pulled apart by the scanning tunnelling microscope tip are sensitive to hydrogen-bonded interactions. Here, we show that these tunnel-decay s...

Event grounding aims at linking mention references in text corpora to events from a knowledge base (KB). Previous work on this task focused primarily single KB event, thereby overlooking the hierarchical aspects of events. Events documents are typically described various levels spatio-temporal granularity. These relations utilized downstream tasks narrative understanding and schema construction...

With an increasingly large amount of sequences properly aligned, comparative sequence analysis can accurately identify not only common structures formed by standard base pairing but also new types of structural elements and constraints. However, traditional methods are too computationally expensive to perform well on large scale alignment and less effective with the sequences from diversified p...

This paper proposes the impacts of event and event actor alignment in English and Bengali phrase based Statistical Machine Translation (PB-SMT) System. Initially, events and event actors are identified from English and Bengali parallel corpus. For events and event actor identification in English we proposed a hybrid technique and it was carried out within the TimeML framework. Events in Bengali...

The event detection is one of the fundamental researches in wireless sensor networks (WSNs). Due to the consideration of various properties that reflect events status, the Composite event is more consistent with the objective world. Thus, the research of the Composite event becomes more realistic. In this paper, we analyze the characteristics of the Composite event; then we propose a criterion ...

This work identifies novel structure-function relationships between Tn5 transposase (Tnp) and its DNA recognition sequence. The Tn5 Tnp-DNA co-crystal structure revealed the protein-DNA contacts of the post-cleavage complex (Davies, D. R., Goryshin, I. Y., Reznikoff, W. S., and Rayment, I. (2000) Science 289, 77-85). One of the most striking features of this complex is the rotation of thymine 2...

We report the first electrophysiological investigation of the inverse base-rate effect (IBRE), a robust non-rational bias in predictive learning. In the IBRE, participants learn that one pair of symptoms (AB) predicts a frequently occurring disease, whilst an overlapping pair of symptoms (AC) predicts a rarely occurring disease. Participants subsequently infer that BC predicts the rare disease,...
