We describe our submissions to the WMT11 shared MT evaluation task: MTeRater and MTeRater-Plus. Both are machine-learned metrics that use features from e-rater R ©, an automated essay scoring engine designed to assess writing proficiency. Despite using only features from e-rater and without comparing to translations, MTeRater achieves a sentencelevel correlation with human rankings equivalent t...

In this paper we analyze the source and level of the marketing gains when structured debt securities are sold at yields that reflect only their credit ratings, or specifically at the yield on an equivalently rated reference bond. We distinguish between credit ratings that are based on probabilities of default and ratings that are based on the expected default losses. We show that the marketing ...

This paper studies the collaborative rating allocation problem, in which each user has limited ratings on all items. These users are termed “energy limited”. Different from existing methods which treat each rating independently, we investigate the geometric properties of a user’s rating vector, and design a matrix completion method on the simplex. In this method, a user’s rating vector is estim...

Recommendation systems are an important units in today’s e-commerce applications, such as targeted advertising, personalized marketing and information retrieval. In recent years, the importance of contextual information has motivated generation of personalized recommendations according to the available contextual information of users. Compared to the traditional systems which mainly utilize use...

Yelp is a popular crowd-sourced local business reviews and social networking platform. For each individual business, users can submit a review on their products or services using a one to five star rating system while interacting with each other through following users and voting on reviews. Having accumulated an enormous amount of data on information, reviews, and ratings of businesses, Yelp h...

This tutorial paper gives a fairly gentle introduction to the basic mathematics required to understand encryption systems. Three main areas are covered: modular arithmetic, prime numbers and probability theory. These should help the reader to understand how conventional and public-key encryption systems work, how they might be attacked and how to improve their security. snellwilcox.com Putting ...

In this paper we analyse the source and magnitude of marketing gains from selling structured debt securities at yields that reflect only their credit ratings, or specifically at yields on equivalently rated corporate bonds. We distinguish between credit ratings that are based on probabilities of default and ratings that are based on expected default losses. We show that subdividing a bond issue...

Over the past few decades, a number of clinician-rated and patient-rated instruments have been developed as primary efficacy measures in depression clinical trials. All those scales have relative strengths and weaknesses and some of them have been more successful than others, and have become the gold standards for depression clinical research. With all these measures available and with the evid...

In the offline world, we look to the people we trust and those they trust for reliable information. In this paper, we present a computational model of this phenomenon and show how it can be used to identify high quality content in an Open Rating System, i.e., a system in which any user can rate content. We present a case study (Epinions.com) of a system based on this model and describe a new pl...
