Abstract

This study is focused on querying accomplished on structured spaces of information. Querying is understood in terms of mining structures of information and of knowledge understanding. We consider information as a subject of descriptions expressed in some language. Information is hidden behind such descriptions. Operations done on structured spaces of information are performed on language constructions describing such structures. However, automatic operations not always can be performed directly on language constructions. In such cases it is necessary to expand performance to the space of information. The study concerns paginated (i.e. printed and handwritten) music notation. It is shown that querying in the space of music information requires syntactic structuring as well as its expansion to semantic analysis. It is worth underlining that data understanding requires analysis of uncertainty: analyzed data are usually incomplete, uncertain and with some incorrectness. Such imperfectness of information is hidden under the level of syntax and semantics. Due to limitation of the paper this problem is not studied.
