This quantity includes the complaints of ICFCA 2004, the second overseas convention on Formal idea research. The ICFCA convention sequence goals to be the most excellent discussion board for the ebook of advances in utilized lattice and order concept and particularly scienti?c advances on the topic of formal suggestion research. Formal inspiration research emerged within the Eighties from e?orts to restructure lattice idea to advertise higher conversation among lattice theorists and potentialusersoflatticetheory.Sincethen,the?eldhasdevelopedintoagrowing study sector in its personal correct with a thriving theoretical neighborhood and a growing number of functions in info and information processing together with info visualization, details retrieval, desktop studying, information research and data administration. by way of thought, formal notion research has been prolonged into characteristic exploration, Boolean judgment, contextual common sense etc to create a strong common framework for wisdom illustration and reasoning. This convention goals to unify theoretical and utilized practitioners who use formal inspiration an- ysis, drawing at the ?elds of arithmetic, computing device and library sciences and software program engineering. The subject of the 2004 convention was once ‘Concept Lattices” to recognize the colloquial time period used for the road diagrams that seem in nearly each paper during this quantity. ICFCA 2004 incorporated educational periods, demonstrating the sensible bene?ts of formal thought research, and highlighted advancements within the foundational idea and criteria. The convention showcased the expanding number of formal inspiration research software program and integrated 8 invited lectures from uncommon speakersinthe?eld.Sevenoftheeightinvitedspeakerssubmittedaccompanying papers and those have been reviewed and seem during this volume.

In order to prove this, for each S ∈ C(Simp (K)) we need to find an (ag )g∈G with ϕ((ag )g∈G ) = S. (g, p) ∈ S}, and for each g ∈ A we consider the set Pg := {p ∈ P(K) | (g, p) ∈ S}. Since S is a closure, we obtain for each g ∈ G that {g} × Pg ⊆ S, thus (g, Pg ) ∈ S. Since Pg is a −semiconcept by definition, we have Pg ∈ hg and hence Pg = [ Pg ). Therefore, S = g∈A {g} × [ Pg ).
