With the advancement in digitalization, archived documents such as newspapers have been increasingly converted into electronic documents and become available for user search. Many of these newspaper articles appear in several publication avenues with some variations. Their presence decreases both effectiveness and efficiency of search engines which directly affects user experience. This emphasizes on development of a duplicate detection method, however, digitized newspapers, in particular, have their own unique challenges. One important challenge that is discussed in this paper is the presence of OCR (Optical Character recognition) errors which negatively affects the value of document collection. The frequency of syndicated stories within the newspaper domain poses another challenge during duplicate/near duplicate detection process. This paper introduces a duplicate detection method based on clustering that detects duplicate/near duplicate digitized newspaper articles. We present the experiments and assessments of the results on three different data subsets obtained from the Trove digitized newspaper collection.
