A Trinity of Trials: Surrey's 2014 Attempts at Author Verification

چکیده
Encouraged by results from our approaches in previous PAN workshops, this paper explores three different approaches using stopword cooccurrence. High frequency patterns of co-occurrence can be used to some extent as identifiers of an author’s style, and have been demonstrated to operate similarly across certain languages without requiring deeper linguistic knowledge. However, making best use of such information remains unresolved. We compare results from applying three approaches overs such patterns: a frequency-mean-variance framework; a positional-frequency cosine comparison approach, and a cosine distance-based approach. A clearly advantageous approach across all languages and genres is yet to emerge.

متن کاملEffect of long-term ageing on i-vector speaker verification
Assessing the impact of ageing on biometric systems is an important challenge. In this paper, an i-vector speaker verification framework is used to evaluate the impact of long-term ageing on state-of-the-art speaker verification. Using the Trinity College Dublin Speaker Ageing (TCDSA) database, it is observed that the performance of the i-vector system, in terms of both discrimination and calib...
متن کاملEigenageing compensation for speaker verification
Dealing with the effect of vocal ageing on speaker verification is an important challenge. In this paper, a new approach to improving speaker verification performance in the presence of long-term ageing is presented. Analogous to eigenchannel compensation, the proposed eigenageing compensation method operates by adapting a speaker model to a test sample based on a predetermined ageing subspace....

This paper briefly describes the approach taken to the subtask of Text Alignment in the Plagiarism Detection track at PAN 14. We have now reimplemented our PAN12 approach in a consistent programmatic manner, courtesy of secured research funding. PAN 14 offers us the first opportunity to evaluate the performance/consistency of this re-implementation. We present results from this re-implementatio...
متن کاملTreatments for Type 2 Diabetes; a Focus on DPP4 Inhibitors
New treatments for diabetes are always exciting in the beginning but as experience grows their position in management becomes less certain. This review focuses on DPP4 inhibitors and their place in management of type 2 diabetes. Although hypoglycaemia is rarely an issue, the effectiveness in reduction in blood sugar is greatest at the higher blood sugar levels, hence much of the value of using ...
