On the Usefulness of Compression Models for Authorship Verification
TLDR
We propose an intrinsic AV method, which yields competitive results compared to a number of current state-of-the-art approaches, based on support vector machines or neural networks. Expand

Authorship Verification in the Absence of Explicit Features and Thresholds
TLDR
We propose a novel parameter-free AV approach, which derives its thresholds for each verification case individually and enables AV in the absence of explicit features and training corpora. Expand

Rethinking the Evaluation Methodology of Authorship Verification Methods
TLDR
We propose an alternative evaluation methodology based on the construction of reliable corpora in combination with a more suitable performance measure. Expand

Authorship Verification based on Compression-Models
TLDR
We propose an intrinsic AV method, which yields competitive results compared to state-of-the-art approaches, based on support vector machines or neural networks. Expand

Cross-Domain Authorship Attribution Based on Compression: Notebook for PAN at CLEF 2018
TLDR
We present a lightweight authorship attribution approach named COBAA ("Compression-Based Authorship Attribution") which is an attempt to answer this question. Expand

An Improved Topic Masking Technique for Authorship Analysis
TLDR
We propose an effective technique called POSNoise, which aims to mask topic-related content in documents and show that it is able to outperform a well-known topic masking approach. Expand

Data Corpora for Digital Forensics Education and Research
TLDR
Data corpora are very important for digital forensics education and research. Expand

Assessing the Applicability of Authorship Verification Methods
TLDR
We propose criteria and properties to improve the characterization of existing and future AV approaches, including the current state-of-the-art. Expand

A Step Towards Interpretable Authorship Verification
TLDR
A central problem that has been researched for many years in the field of digital text forensics is the question whether two documents were written by the same author. Expand
