Querying a Bioinformatic Data Sources Registry with Concept Lattices
Abstract Bioinformatic data sources available on the web are multiple and heterogenous. The lack of documentation and the difficulty of interaction with these data banks require us...

A Generalized-Zero-Preserving Method for Compact Encoding of Concept Lattices
Constructing an encoding of a concept lattice using short bit vectors allows for efficient computation of join operations on the lattice. Join is the central operation any unifica...

Replacing full rectangles by dense rectangles: Concept lattices and attribute implications
— Maximal full rectangles in tabular data are useful in several areas of data engineering. This paper presents a survey of results in which we replace “full rectangles” by ...

Yet a Faster Algorithm for Building the Hasse Diagram of a Concept Lattice
Formal concept analysis (FCA) is increasingly applied to data mining problems, essentially as a formal framework for mining reduced representations (bases) of target pattern famili...

A Concept Lattice-Based Kernel for SVM Text Classification
Abstract. Standard Support Vector Machines (SVM) text classification relies on bag-of-words kernel to express the similarity between documents. We show that a document lattice can ...
