relatively recently, there are a few research works that are devoted to this topic. In this paper, we are focusing on using Twitter, the most popular micro blogging platform, for the task of Emotion analysis. We will show how to automatically collect a corpus for Emotion analysis and opinion mining purposes
Artist classification with web-based data
- in Proc. Int. Symp. on Music Information Retrieval (ISMIR’04
, 2004
"... Manifold approaches exist for organization of music by genre and/or style. In this paper we propose the use of text categorization techniques to classify artists present on the Internet. In particular, we retrieve and analyze webpages ranked by search engines to describe artists in terms of word occ ..."

TRank: ranking Twitter users according to specific topics
"... Abstract-Twitter is the most popular real-time microblogging service and it is a platform where users provide and obtain information at rapid pace. In this scenario, one of the biggest challenge is to find a way to automatically identify the most influential users of a given topic. Currently, there ..."

, there are several approaches that try to address this challenge using different Twitter signals (e.g., number of followers, lists, metadata), but results are not clear and sometimes conflicting. In this paper, we propose TRank, a novel method designed to address the problem of identifying the most influential
UKPDIPF: A Lexical Semantic Approach to Sentiment Polarity Prediction in Twitter Data
"... We present a sentiment classification sys-tem that participated in the SemEval 2014 shared task on sentiment analysis in Twit-ter. Our system expands tokens in a tweet with semantically similar expressions us-ing a large novel distributional thesaurus and calculates the semantic relatedness of the e ..."

Studying aesthetics in photographic images using a computational approach
- In Proc. ECCV
, 2006
"... Abstract. Aesthetics, in the world of art and photography, refers to the principles of the nature and appreciation of beauty. Judging beauty and other aesthetic qualities of photographs is a highly subjective task. Hence, there is no unanimously agreed standard for measuring aesthetic value. In spit ..."

Automated classifiers are built using support vector machines and classification trees. Linear regression on polynomial
Ranking-Based Classification of Heterogeneous Information Networks
"... It has been recently recognized that heterogeneous information networks composed of multiple types of nodes and links are prevalent in the real world. Both classification and ranking of the nodes (or data objects) in such networks are essential for network analysis. However, so far these approaches ..."

Making sense of Twitter Search
"... Twitter provides a search interface to its data, along the lines of traditional search engines. But the single ranked list is a poor way to represent the richlystructured Twitter data. A more structured approach that recognizes original messages, re-tweets, people, and documents as interesting const ..."

Label Ranking by Learning Pairwise Preferences
"... Preference learning is an emerging topic that appears in different guises in the recent literature. This work focuses on a particular learning scenario called label ranking, where the problem is to learn a mapping from instances to rankings over a finite number of labels. Our approach for learning s ..."

such a mapping, called ranking by pairwise comparison (RPC), first induces a binary preference relation from suitable training data using a natural extension of pairwise classification. A ranking is then derived from the preference relation thus obtained by means of a ranking procedure, whereby different
