SQSE: A Measure to Assess Sample Quality of Authorial Style as a Cognitive Biometric Trait

Abstract

Topic (FICSIT) corpus is controlled precisely for cross-topic samples. The corpus was compiled from data dumps provided by StackExchange 2 . The StackExchange network contains a large collection of different question-answer forums spanning 176 sites with over three million users. Out of all the topics available on the StackExchange network, cross-topic data was extracted for users contributing to two or more topics. This requirement was satisfied by 293,415 users, who were again constrained to at least 70 samples per user. Finally, a cross-topic corpus was obtained with 308 topics and 188,077 text samples for 1,237 distinct authors. No other pre-processing steps were performed on the collected data. A summary of the corpus statistics for FICSIT is given in Table 1.
