Italian, Greek, Spanish and German. The main advantage of the FCD with 308 respect to traditional compression-based methods, apart from the reduced 309 computational complexity, is that it yields more accurate results. We can 310 justify this with two remarks: firstly, the FCD should be more robust since it 311 performs a word-based analysis, focusing exclusively on meaningful patterns 312 which better capture the information contained in the documents; secondly, 313 the use of a full dictionary allows discarding any limitation that real compres- 314 sors have concerning the size of buffers and lookup tables employed, being 315 the size of the dictionaries bounded only by the number of relevant patterns 316 contained in the objects. At the same time, the data-driven approach typi- 317 cal of NCD is maintained. This allows keeping an objective, parameter-free 318 workflow for all the problems considered in the applications section, in which 319 promising results are presented on collections of texts in Italian, English, and 320 German. 321 323 324 325 326 327 328 References 322 Adair, D., 1974.
