A clustering approach to extract data from HTML tables
نویسندگان
چکیده
HTML tables have become pervasive on the Web. Extracting their data automatically is difficult because finding relationships between cells not trivial due to many different layouts, encodings, and formats available. In this article, we introduce Melva, which an unsupervised domain-agnostic proposal extract from without requiring any external knowledge bases. It relies a clustering approach that helps make label apart value establish relationships. We compared Melva four competitors more than 3000 Wikipedia Dresden Web Table Corpus. The conclusion our 21.70% better best competitor equals supervised regarding effectiveness, but it 99.14% efficiency.

Table is a very common presentation scheme, but few papers touch on table extraction in text data mining. This paper focuses on mining tables from large-scale HTML texts. Table filtering, recognition, interpretation, and presentation are discussed. Heuristic rules and cell similarities are employed to identify tables. The F-measure of table recognition is 86.50%. We also propose an algorithm to...
