CRIS Current Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishSeveral efficient and very powerful algorithms exist for detecting changes in tree-based textual documents, such as those encoded in XML. An important aspect is still underestimated in their design and implementation: the quality of the output, in terms of readability, clearness and accuracy for human users. Such requirement is particularly relevant when diff-ing literary documents, such as books, articles, reviews, acts, and so on. This paper introduces the concept of ’naturalness’ in diff-ing tree-based textual documents, and discusses a new extensible set of changes which can and should be detected. A naturalness-based algorithm is presented, as well as its application for diff-ing XML-encoded legislative documents. The algorithm, called JNDiff, proved to detect significantly better matchings (since new operations are recognized) and to be very efficient.

| Abstract: | Several efficient and very powerful algorithms exist for detecting changes in tree-based textual documents, such as those encoded in XML. An important aspect is still underestimated in their design and implementation: the quality of the output, in terms of readability, clearness and accuracy for human users. Such requirement is particularly relevant when diff-ing literary documents, such as books, articles, reviews, acts, and so on. This paper introduces the concept of ’naturalness’ in diff-ing tree-based textual documents, and discusses a new extensible set of changes which can and should be detected. A naturalness-based algorithm is presented, as well as its application for diff-ing XML-encoded legislative documents. The algorithm, called JNDiff, proved to detect significantly better matchings (since new operations are recognized) and to be very efficient. | |
