Recently, several properties of complex fuzzy sets are introduced to measure the changes in dynamic or periodic fuzzy attributes using its amplitude and phase terms. In this process, a problem is observed while discovering some of the meaningful information from the given complex data sets for the knowledge processing tasks.

The paper presents theorems characterizing concept lattices which happen to be trees after removing the bottom element. Concept lattices are the clustering/classification systems provided as an output of formal concept analysis. In general, a concept lattice may contain overlapping clusters and need not be a tree.

The basic notions of Formal Concept Analysis are those of a formal context and a formal concept. The adjective “formal” is meant to emphasize that we are dealing with mathematical notions, which only reflect some aspects of the meaning of context and concept in standard language.

Quotient lattice and incremental construction of concept lattices
The 2nd International Conference on Information Science and Engineering, 2010Concept lattice which is the core data structure in formal concept analysis has proved to be a useful tool in many applied domains: machine learning, software engineering and information retrieval, etc. The problem of constructing concept lattices is extensively studied and among various kinds of algorithms published so far, incremental ones which ...

Approximations in Concept Lattices
2010Motivated by Rough Set Theory we describe an interval arithmetic on complete lattices. Lattice elements get approximated by approximations which are pairs consisting of a lower and an upper approximation. The approximations form a complete lattice again. We describe these lattices of approximations by formal contexts.
