We describe the fifth edition of CheckThat! lab, part 2022 Conference and Labs Evaluation Forum (CLEF). The lab evaluates technology supporting tasks related to factuality in multiple languages: Arabic, Bulgarian, Dutch, English, German, Spanish, Turkish. Task 1 asks identify relevant claims tweets terms check-worthiness, verifiability, harmfullness, attention-worthiness. 2 detect previously fa...

this study is to report characteristics of people killed in road traffic crashes and to describe major patterns of traffic crashes in china.descriptive and inferential statistical analyses were conducted. road traffic death national data, population denominator data and motor vehicles data of 2009 were obtained from the bureau of traffic management at ministry of public security and national bu...

market crash is a phenomenon which occurs in stock markets occasionally and leads to loss of the investors’ wealth and assets in a relatively short period of time. therefore, attempts for prediction of this phenomenon are of much importance for the investors, financial institutions and government. to this date, numerous and varied studies have been carried out for predicting and modeling  stock...

The likelihood of a crash or crash potential is significantly affected by short-term turbulence of traffic flow. For this reason, crash potential must be estimated on a real-time basis by monitoring the current traffic condition. In this regard, a probabilistic real-time crash prediction model relating crash potential to various traffic flow characteristics which lead to crash occurrence, or “c...

a spinal cord injury (sci) refers to any injury to the spinal cord or nerves at the end of the spinal canal that is caused by trauma instead of disease often causes permanent changes in strength, sensation and other body functions below the site of the injury. road traffic collision (rtc) or car crash occurs when a vehicle collides with another vehicle, pedestrian, animal, road debris, or other...

Most states currently use ranking procedures to identify intersections with safety concerns. One objective of a state intersection ranking procedure is to provide a reliable start to the prioritization of safety improvements. For efficiency purposes, it is crucial to have a ranking system that identifies intersections with the most severe safety concerns. Otherwise, potentially hazardous inters...

Although speed is considered to be one of the main crash contributory factors, research findings are inconsistent. Independent of the robustness of their statistical approaches, crash frequency models typically employ crash data that are aggregated using spatial criteria (e.g., crash counts by link termed as a link-based approach). In this approach, the variability in crashes between links is e...

This paper proposes and examines modifications for the method of Latent Semantic Analysis (LSA). Several new local and global weight functions, along with normalization routines, are disclosed. Changes in the general structure of LSA are discussed. An application of LSA, in which the method is used to filter advertisements in e-mail, proves the worthiness of the advancements.
