Duplicate Detection with Efficient Language Models for Automatic Bibliographic Heterogeneous Data Integration

We present a new method to detect duplicates used to merge different bibliographic record corpora with the help of lexical and social information. As we show, a trivial key is not available to delete useless documents. Merging heteregeneous document databases to get a maximum of information can be of interest. In our case we try to build a document corpus about the TOR molecule so as to extract relationships with other gene components from PubMed and WebOfScience document databases. Our approach makes key fingerprints based on n-grams. We made two documents gold standards using this corpus to make an evaluation. Comparison with other well-known methods in deduplication gives best scores of recall (95%) and precision (100%).
