dc.description.abstract-translatedThere is a large amount of data available on the Web. Data are often represented as text, enriched with tables, lists, images or other visual structures. These data are usually coded in HTML without any additional semantics, which makes them nigh impossible to automatically process and extract. There are ap-proaches based on top-down document segmentation according to visual infor-mation and layout. We present a bottom-up approach which starts with the smallest consistent elements and matches the visual relationships among these elements to a pre-defined ontological structure of extracted records. This meth-od considers not only the visual attributes of a particular segment, but also its position amongst other segments.en
