I am new user of Rapidminer and I like to konw if there is some operators or some process made to show inconsistency or incompleteness in a database. ???
For me inconsistency is some mistakes in database wich can be bad for the integrity. For example, orthograph mistakes in the name of people. The architecture of my database is the following : /phdthesis/#id | /phdthesis/@key| /phdthesis/@mdate| /phdthesis/author| /phdthesis/ee| /phdthesis/isbn| /phdthesis/school | /phdthesis/title | /phdthesis/url | /phdthesis/year
and I am trying to underline the fact that wrong orthograph in the name of the autor lead inconsistency problem.
unfortunately finding spelling errors is not the main focus of RapidMiner. It would be possible to create a process to do something like that, but unless you want to do further data processing, ETL and data analysis I would probably use another tool for finding the orthographic mistakes.
Hm, no, not really. The k-NN operator is used for classification problems. You are right in that it creates its predictions by comparing new instances to the nearest, i.e. most similar other instances, but the user does not have access to these comparisons, but only sees the final prediction.
In any case, unfortunately, it cannot be used to find spelling errors.
