Authorship analysis aims at classifying texts based on the stylistic choices of their authors.
The idea is to discover characteristics of the authors of the texts.
This task has a growing importance in forensics, security, and marketing.
In this work, we focus on discovering age and gender from blog authors.
With this goal in mind, we analyzed a large number of features -- ranging from Information Retrieval to Sentiment Analysis.
This paper reports on the usefulness of these features.
Experiments on a corpus of over 236K blogs show that a classifier using the features explored here have outperformed the state-of-the art.
More importantly, the experiments show that the Information Retrieval features proposed in our work are the most discriminative and yield the best class predictions.
