Methods of Data Extraction from the Web
Perina, Lukáš ; Křivka, Zbyněk (oponent) ; Burget, Radek (vedoucí práce)
The purpose of this bachelor thesis is to design an architecture and subsequent implementation of an application designed for data extraction (web scraping) from web documents. Unlike conventional methods, it is an extraction based on defining data types and regular expressions of requested elements. Extraction is executed in such a manner, where it is not necessary to know the detailed structure of given web document and the possibility of using just one definition to detect requested elements on different web pages. Algorithm is able to achieve overall accuracy of 85,51% and recall 80,28%. This approach can reduce the time required for analysis of web pages significantly and not to take the structure of the code as a determining factor while creating web scraping requests.
