Comparison between Scrapple & Ducky

From the experiments performed with the Scrapple framework, we see that correctly written configuration files give accurate results. In the single page linear extractor example and link crawler example (where over 2800 pages were crawled through), an accuracy level of 100% was achieved.

The accuracy of the implementation of the Scrapple framework is dependent on the user’s understanding of web structure and the ability to write correct selector expressions.

On comparison with Ducky [1], it can be seen that Ducky also provides an accuracy of 100%. The primary difference between the Scrapple framework and the Ducky framework is the features provided.
