Retrieving relevant tweets corresponding to cultural events can be used in various applications like event reporting, event recommendation, etc. This type of retrieval is challenging due to short length of the tweet, noise, out of vocabulary words, abbreviations in the tweet. In this paper, we focus on the problem of retrieving relevant tweets related to given cultural event of a festival. We c...

Not much is known about event apprehension, the earliest stage of information processing in elicited language production studies, using pictorial stimuli. A reason for our lack of knowledge on this process is that apprehension happens very rapidly (<350 ms after stimulus onset, Griffin & Bock 2000), making it difficult to measure the process directly. To broaden our understanding of apprehensio...

The most precise top quark mass measurements use kinematic reconstruction methods, determining the top mass parameter of a Monte Carlo event generator m_{t}^{MC}. Because of hadronization and parton-shower dynamics, relating m_{t}^{MC} to a field theory mass is difficult. We present a calibration procedure to determine this relation using hadron level QCD predictions for observables with kinema...

This paper addresses the problem of predicting the k events that are most likely to occur next, over historical real-time event streams. Existing approaches to causal prediction queries have a number of limitations. First, they exhaustively search over an acyclic causal network to find the most likely k effect events; however, data from real event streams frequently reflect cyclic causality. Se...

Single-lepton plus jets signals from t ¯ t production at hadron colliders generally give more spherically symmetrical events than the principal backgrounds from W production. We show that sphericity and aplanarity criteria, applied to lepton plus neutrino plus four jet final states at the Fermilab Tevatron p¯ p collider, help to discriminate; they can be used either to validate an eventual top ...

This paper describes the preliminary work on the project of extending the BulTreeBank with temporal information that will serve as a golden standard for Bulgarian language. We outline a flexible markup scheme that is based on a language-specific verb taxonomy and test its capabilities by implementing algorithms for temporal entities recognition in the CLaRK System tool.

A Binary Decision Diagram (BDD) [1-3] provides an efficient representation and manipulation of Boolean formulae, and it was shown that a BDD is effective in the diverse fields of computer science and reliability [4]. Bryant [3] popularized the use of a BDD by developing a set of algorithms for an efficient construction and manipulation of BDDs. The BDD algorithm was applied to a reliability ana...

This paper is about a new type of event database that enables efficient reasoning about things, people, companies, relationships between people and companies, and about places and events. The event database is built on top of a scalable distributed RDF triple store that can handle literally billions of events. Like objects, events have at least one actor, but usually more, a start-time and poss...

Recent measurements of the mass of the top quark (t) are presented using 162 pb of data of pp collisions at √ s = 1.96TeV collected by the CDF detector at the Tevatron collider during Run II. The analyses focus on the semi-leptonic decay mode tt̄ → (blν)(bqq̄) with one or two identified bottom quarks (b). The Template Method (TM) reconstructs the invariant mass of the top quark in each event. The...
