Background: The purpose of this study is to evaluate the number of reviews and scores for active members of the American Society for Surgery of the Hand (ASSH) in popular physician rating websites (Healthgrades.com and Vitals.com). Methods: A total of 433 ASSH active members were searched in two popular rating websites for a total of 866 web searches. Demographic data, overall and subcategory ...

In this paper we first propose a new statistical parsing model, which is a generative model of lexicalised context-free grammar. We then extend the model to include a probabilistic treatment of both subcategorisation and wh-movement. Results on Wall Street Journal text show that the parser performs at 88.1/87.5% constituent precision/recall, an average improvement of 2.3% over (Collins 96).

A. Clark[2] has shown that the class of languages which have a context-free grammar whose nonterminals can be defined by a finite set of contexts can be identified in the limit, given an enumeration of the language and a test for membership. We show by example that Clark’s algorithm may converge to a grammar that does not define the input language. We review the theoretical background, provide ...

In this paper, we introduce a new normal form for context-free grammars, called reversible context-free grammars, for the problem of learning context-free grammars from positive-only examples. A context-free grammar G = (N, Z, P, S) is said to be reversible if (1) A + G( and B -+ a in P implies A = B and (2) A -+ a@ and A --f aCfl in P implies B = C. We show that the class of reversible context...

In the age of digital economy, customers actively share their experiences and issues about products via online product reviews. Mining potential improvement ideas from customer needs could provide valuable insights into new functionality expected by markets. Numerous studies have attempted to identify using these reviews, but they paid less attention customer’s specific context in which was use...

This paper presents a reranking approach to combining constituent and dependency parsing, aimed at improving parsing performance on both sides. Most previous combination methods rely on complicated joint decoding to integrate graphand transition-based dependency models. Instead, our approach makes use of a high-performance probabilistic context free grammar (PCFG) model to output k-best candida...

Combining the 1-best output of multiple parsers via parse selection or parse hybridization improves f-score over the best individual parser (Henderson and Brill, 1999; Sagae and Lavie, 2006). We propose three ways to improve upon existing methods for parser combination. First, we propose a method of parse hybridization that recombines context-free productions instead of constituents, thereby pr...

Background: Investment in science is vital for the development and well-being of societies. This study aims to assess the scientific productivity of countries by quantifying their publication of systematic reviews taking the gross national income per capita (GNIPC) into account. Methods: Medline and ISI Web of Science were searched for systematic reviews published between 1st January 2006 an...
