A methodology for obtaining the discrimable matrix or table (more decisive attributes) and knowledge reduction for the above information system is proposed.
Especially, the related family-based approaches have been provided for attribute reduction of covering information systems.
Finally, we apply the obtained matroids to attribute reduction issues in information systems.
Many attribute reduction algorithms were designed for the static information system in the past years.
We firstly employ belief and plausibility functions to measure lower and upper approximations in neighborhood-covering rough sets, and then, the attribute reductions of covering information systems and decision systems are characterized by these respective functions.
Computing the core of decision information system and designing efficient relative attribution reduction algorithms are the main research content in rough set theory.
They demonstrated an 87% reduction of reporting errors in health centers using the e-Chasqui electronic laboratory information system compared with those using a paper-based system through reductions in missing results.
The reduction in the labor costs to operate the building is about US$20,0000 per year, which alone could pay for the information system in about 5 years.
