Building unified timelines from a collection of written news articles requires cross-document event coreference resolution and temporal relation extraction. In this paper we present an approach event coreference resolution according to: a) similar temporal information, and b) similar semantic arguments. Temporal information is detected using an automatic temporal information system (TIPSem), wh...

Distant supervision usually utilizes only unlabeled data and existing knowledge bases to learn relation extraction models. However, in some cases a small amount of human labeled data is available. In this paper, we demonstrate how a state-of-theart multi-instance multi-label model can be modified to make use of these reliable sentence-level labels in addition to the relation-level distant super...

OBJECTIVES The purpose of this study was to evaluate the relationship between calcification in tibial arteries, the degree of limb ischemia, and the near-term risk of amputation. BACKGROUND Determining the amputation risk in patients with peripheral arterial disease (PAD) remains difficult. Developing new measures to identify patients who are at high risk for amputation would allow for target...

This paper describes the outcomes of the TimeLine task (Cross-Document Event Ordering), that was organised within the Time and Space track of SemEval-2015. Given a set of documents and a set of target entities, the task consisted of building a timeline for each entity, by detecting, anchoring in time and ordering the events involving that entity. The TimeLine task goes a step further than previ...

BACKGROUND A variety of studies have linked childhood maltreatment to headaches, including migraines, and to headache severity. This study assesses the relationship of adverse childhood experiences (ACEs) to frequent headaches during adulthood. METHODS We used data from the Adverse Childhood Experiences (ACE) study, which included 17,337 adult members of the Kaiser Health Plan in San Diego, C...

introduction: hot flashes (hf) and night sweats (ns) are due to vasomotor instability and could be recognized as cardiovascular risk markers. therefore, this study aimed to evaluate the relationship between vasomotor instability and severity of coronary artery disease (cad) in postmenopausal women.  materials and methods: this observational cross sectional study, was performed in chamran hospit...

Abstract Background Leukemia is the most prevalent childhood cancer, and Acute Lymphoblastic Leukemia (ALL) constitutes 75% of all cases. Some epidemiological studies have shown a relationship between socioeconomic status (SES) and some childhood cancers. In the present study, an attempt was made to assess socioeconomical status in a case-control study. Materials and Methods In 2010, a c...
