Towards End-to-End Transformation of Arbitrary Tables from Untagged Portable Documents (PDF) to Linked Data
2019
Scientific-practical Workshop Information Technologies: Algorithms, Models, Systems
Preserved Fulltext
We consider some perspective approaches for the deeplearning-based table detection, heuristic-based table structure recognition, rule-based table analysis, and knowledge-based table interpretation. ...
Our application experience confirms that such solutions are demanded for populating databases and generating ontologies with tabular data being extracted from weakly and semi-structured documents. ...
Additionally, ad-hoc heuristics can be handcrafted and tuned for various domain-specific PDF documents. ...
