V. DISCUSSION & CONCLUSION As shown, the CPA and COA offer substantial advantages in identifying related documents in comparison to existing approaches. However, it should also be taken into account that the effort is considerable. It is not sufficient to evaluate the bibliography of documents, but it is necessary to process the complete document, identify each reference and map it to the corresponding entry in the bibliography, which is in practice not always possible, and leads in ca. 3% of cases to mismatches. This is because sometimes only an abstract and the bibliography can be accessed, documents cannot be parsed as OCR fails, or a reference style is used that makes it unfeasible to automatically link references to the corresponding items in the bibliography. This leads to the conclusion that although these new approaches deliver superior results, they cannot completely replace the already existing approaches, but should be used in combination.
