Today, a huge amount of unstructured tabular data is contained in tables from different sources, e.g. image documents, web pages, and spreadsheets. Sometimes these tables are only available data source. To use that information in business intelligence we need to transform data from these tables to structured form like relational databases. We propose an approach to the tabular data transformation from unstructured (spreadsheets) to structured (relational databases) form using a rule engine. Our table interpretation rules can use spatial, style (typographical), and natural language information from tables. The experimental evaluation shows that the approach can be applied to a wide range of tables from statistical and financial reports.

The paper describes the background and prospects of the development of the spatial data infrastructure (SDI) in the scientific institutions of the Mongolian Academy of Sciences (MAS). This paper also discusses the integration of information resources for the development of SDI. Some original technological solutions are proposed for building SDI in the MAS based on international standards.
Quadratic programming problems (QP) arise in a vast variety of real-world applications in finance, engineering, operational research, and many other fields. A huge number of methods and their various modifications hav...
