Šimon Suchomel, Michal Brandejs
2015 Lecture Notes in Computer Science  
The paper shows the pros and cons of the stop words removal for the sliding window document profiling and discusses the utilization of the selected feature for intrinsic plagiarism detection.  ...  It was conducted for a vocabulary richness method called 'average word frequency class' using the PAN 2015 source retrieval training corpus for plagiarism detection.  ...  On the other hand, if a class change between two neighbouring plagiarized passages is detected the intrinsic plagiarism detection is successful, and so there is no need for the classification method to  ...

Using Clustering to Identify Outlier Chunks of Text - Notebook for PAN at CLEF 2011

Navot Akiva
2011 Conference and Labs of the Evaluation Forum  
Intrinsic plagiarism detection is a sub-task of authorship identification in which outlier chunks must be detected solely on the basis of stylistic differences from the main body of the text.  ...  In the first phase of our method we cluster chunks of text represented by usage of infrequent words. In the second phase, we use a training corpus to identify cluster properties of outlier chunks.  ...  Outlier Chunks Identification Our approach consists of two phases: chunks clustering and cluster properties detection.  ...

Experiments on Document Chunking and Query Formation for Plagiarism Source Retrieval

Amit Prakash, Sujan Kumar Saha
2014 Conference and Labs of the Evaluation Forum  
Our work is focused on intelligent chunking of suspicious documents and a hybrid approach of query formation.  ...  A method based on term frequency and word co-occurrence is proposed to extract query terms from a non-overlapping chunk of topically related sentences.  ...  The plagiarism detection method we proposed does minimal computations and performs the task at a speed suitable enough for practical applications.  ...
