Recovering the logical structure of tables from unstructured texts based on logical inference
The paper addresses the issues on the automation for structuring of tabular information that was originally presented in an unstructured form. An approach for this analysis was suggested as a table structure (i.e. recovering relations of its elements) using the rule engine. The table model and the tabular information processing algorithms are also considered in the paper. Based on the approach, models and algorithms, a system for structuring of the unstructured tabular information presented in spreadsheet format was developed. The experimental results obtained with the help of the proposed approach show the effectiveness of the approach for a wide range of tables.
