Sentiment of Emojis.

Abstract: There is a new generation of emoticons, called emojis, that is increasingly being used in mobile communications and social media. In the past two years, over ten billion emojis were used on Twitter. Emojis are Unicode graphic symbols, used as a shorthand to express concepts and ideas. In contrast to the small number of well-known emoticons that carry clear emotional contents, there are hundreds of emojis. But what are their emotional contents? We provide the first emoji sentiment lexicon, called the Emoji Sentiment Ranking, and draw a sentiment map of the 751 most frequently used emojis. The sentiment of the emojis is computed from the sentiment of the tweets in which they occur. We engaged 83 human annotators to label over 1.6 million tweets in 13 European languages by the sentiment polarity (negative, neutral, or positive). About 4% of the annotated tweets contain emojis. The sentiment analysis of the emojis allows us to draw several interesting conclusions. It turns out that most of the emojis are positive, especially the most popular ones. The sentiment distribution of the tweets with and without emojis is significantly different. The inter-annotator agreement on the tweets with emojis is higher. Emojis tend to occur at the end of the tweets, and their sentiment polarity increases with the distance. We observe no significant differences in the emoji rankings between the 13 languages and the Emoji Sentiment Ranking. Consequently, we propose our Emoji Sentiment Ranking as a European language-independent resource for automated sentiment analysis. Finally, the paper provides a formalization of sentiment and a novel visualization in the form of a sentiment bar.

C# Language Specification

Abstract: C# is a simple, modern, object-oriented, and type-safe programming language that combines the high productivity of rapid application development languages with the raw power of C and C++. Written by the language's architect and design team members, The C# Programming Language is the definitive technical reference for C#. Moving beyond the online documentation, the book provides the complete specification of the language along with descriptions, reference materials, and code samples from the C# design team.The first part of the book opens with an introduction to the language to bring readers quickly up to speed on the concepts of C#. Next follows a detailed and complete technical specification of the C# 1.0 language, as delivered in Visual Studio .NET 2002 and 2003. Topics covered include Lexical Structure, Types, Variables, Conversions, Expressions, Statements, Namespaces, Exceptions, Attributes, and Unsafe Code.The second part of the book provides an introduction to and technical specification of the four major new features of C# 2.0: Generics, Anonymous Methods, Iterators, and Partial Types.Reference tabs and an exhaustive print index allow readers to easily navigate the text and quickly find the topics that interest them most. An enhanced online index allows readers to quickly and easily search the entire text for specific topics.With the recent acceptance of C# as a standard by both the International Organization for Standardization (ISO) and ECMA, understanding the C# specification has become critical. The C# Programming Language is the definitive reference for programmers who want to acquire an in-depth knowledge of C#.0321154916B10142003

Document Object Model (DOM) Level 2 Specification

Abstract: This specification defines the Document Object Model Level 2, a platform- and language-neutral interface that allows programs and scripts to dynamically access and update the content, structure and style of documents. The Document Object Model Level 2 builds on the Document Object Model Level 1. The DOM Level 2 is made of a set of core interfaces to create and manipulate the structure and contents of a document and a set of optional modules. These modules contain specialized interfaces dedicated to XML, HTML, an abstract view, generic stylesheets, Cascading Style Sheets, Events, traversing the
