Description: 形式概念分析，概念格算法
包含两个算法，一个算法是对给定的概念上下文数据集并生成概念格，另一个算法则是绘制出概念格的图。-This demo shows two algorithms related to Formal Concept Analysis. Algorithm one calculates all Formal Concepts contained in a given Formal Context. The second algorithm draws a Formal Concept Lattice corresponding to the given Context. The Lattice is not drawn taking any aesthetic considerations into account. This will be part of future enhancements. The program was written using Java (my first Java experience, a quite complex "Hello World"). Platform: |

Description: Code duplication exists for many reasons, although it is known to be a bad practice. It
may save costs on the development phase, but it surely has a higher cost of maintenance.
What can we do to detect and eliminate those problems?
This document shows how to use the mathematical foundation of Formal Concept
Analysis to detect code duplication.
Formal Concept Analysis allows us to identify concepts, or groupings of elements, that
have common properties. We work with a particular kind of elements and properties:
Methods containing similar Regular Parse Tree Expressions. We classify these concepts
in a certain way to reveal candidates for code duplication refactorings and show them in
an ordered way, so that the user can decide to apply the refactoring when needed.
This work is done as an extension of the existing Delfstof framework for VisualWorks
Smalltalk, which is currently being developed by researchers at CWI1 and UCL. Platform: |

Description: 概念格的构造问题是形式概念分析应用的前提。由于概念格的时空复杂度随着形式背景的增大而可能指数性的增大，有关概念格的生成问题一直是形式概念分析应用研究的一个重点。国内外的学者和研究人员对此进行了深入的研究，提出了一些有效的算法来生成概念格，这些算法一般可分为两类：批生成算法(Batch Algorithm)和渐进式生成算法(Incremental Algorithm )。。
-Concept lattice structure problem is the premise formal concept analysis applications. Since the concept of space-time lattice with the increasing complexity of the form and context may increase exponentially, generating questions about the concept lattice has been a focus of formal concept analysis applied research. Domestic and foreign scholars and researchers conducted a thorough study made a number of efficient algorithms to generate the concept lattice, these algorithms can be divided into two categories: batch generation algorithm (Batch Algorithm) and progressive generation algorithm (Incremental Algorithm ). .

Description: 概念格建格代码，模型的建立概念格（Concept Lattice）是一个以概念为元素的偏序集，它可以通过Hasse图可视化，其中每个节点是一个概念。概念格结构模型来源于形式概念分析（FCA）理论，是FCA中的核心数据分析工具，它本质上描述了对象（样本）与属性（特征）之间的关联。[1](The concept lattice (Concept, Lattice) is a poset of concept elements, which can be visualized by Hasse diagrams, where each node is a concept. The concept lattice structure model, derived from formal concept analysis (FCA) theory, is the core data analysis tool in FCA, which essentially describes the association between objects (samples) and attributes (features)) Platform: |
