Distinguishing the flavor of B and B hadrons is critical in studies of CP-violation, B 0 − B 0 mixing, and the underlying b-decay mechanisms. Methods of b " flavor tagging " are broadly divided into " opposite b " tagging and self-tagging of the signal b hadron. The former, while understood, has the perceived drawback of low efficiency. The latter, while having the potential for an order of mag...

The number of word forms in agglutinative languages is theoretically infinite and this variety in word forms introduces sparsity in many natural language processing tasks. Part-of-speech tagging (PoS tagging) is one of these tasks that often suffers from sparsity. In this paper, we present an unsupervised Bayesian model using Hidden Markov Models (HMMs) for joint PoS tagging and stemming for ag...

A type flaw attack on a security protocol is an attack where a field in a message that was originally intended to have one type is subsequently interpreted as having another type. Heather et al. proves that type flaw attacks can be prevented with the technique of tagging each field with the information that indicates its intended type. We simplify Heather et al.’s tagging scheme by combining al...

While recent progress has been achieved in understanding the structure and dynamics of social tagging systems, we know little about the underlying user motivations for tagging, and how they influence resulting folksonomies and tags. This paper addresses three issues related to this question: 1.) What motivates users to tag resources, and in what ways is user motivation amenable to quantitative ...

In recent years, tagging systems have become increasingly popular. These systems enable users to add keywords (i.e., “tags”) to Internet resources (e.g., web pages, images, videos) without relying on a controlled vocabulary. Tagging systems have the potential to improve search, spam detection, reputation systems, and personal organization while introducing new modalities of social communication...

Although user tagging of library resources shows substantial promise as a means of improving the quality of users’ access to those resources, several important questions about the level and nature of the warrant for basing retrieval tools on user tagging are yet to receive full consideration by library practitioners and researchers. Among these is the simple evaluative question: What, specifica...
