The goal of this paper is to show a connection between FCA generalisations and the Chu construction on the category ChuCors, the category of formal contexts and Chu correspondences. All needed categorical properties like categorical product, tensor product and its bifunctor properties are presented and proved. Finally, the second order generalisation of FCA is represented by a category built up...

Since the Civil War, False Claims Act has served as a tool to combat fraud perpetrated against government. Early by government contractors during War was quaint: selling same horse twice or filling Union Army contract for sugar with sand. Today, recovers billions of dollars annually through actions under FCA. Essential FCA’s functioning are “relators,” private citizens who serve whistleblowers ...

The booming of Social Internet Things (SIoT) has witnessed the significance graph mining and analysis for social network management. Online Networks (OSNs) can be efficiently managed by monitoring users’ behaviors within a cohesive group represented maximal clique. They further provide valued intelligence their users. Maximal Cliques Problem (MCP) as fundamental problem in is to identify clique...

In this paper, we present a browsing framework for digitised cultural collections. Using a data analysis technique called Formal Concept Analysis (FCA), units of thought can be constructed from a series of objects and their tags. FCA can dynamically generate links in between objects and induce a serendipitous browsing experience using a relatively simple data structure. We evaluate the utility ...

Classical Formal Concept Analysis (FCA) extracts, represents and manages knowledge from positive information, i.e., its fundamental data model is a binary relation between a set of objects and attributes indicating the presence of a property in an object. However, some applications require to treat the absence of some property in an object as a negative information to be explicitly represented ...

Recycling implies additional costs for separated municipal solid waste (MSW) collection. The aim of the present study is to propose and implement a management tool - the full cost accounting (FCA) method - to calculate the full collection costs of different types of waste. Our analysis aims for a better understanding of the difficulties of putting FCA into practice in the MSW sector. We propose...

Recent literature reports the growing interests in data analysis using Formal Concept Analysis (FCA), in which data is represented in the form of object and attribute relations. FCA analyzes and then subsequently visualizes the data based on duality called Galois connection. Attribute exploration is a knowledge acquisition process in FCA, which interactively determines the implications holding ...

Our aim was to determine whether tantalum m arkers improved the accuracy and/or precision of methods for the measurement of migration in total hip replacement based on conventional measurements without mathematical correction of the data, and with Ein Bild Roentgen Analyse - Femoral Component Analysis (EBRA-FCA) which allows a computerised correction. Three observers independently analysed 13 s...

The simple formalization and the intuitive graphical representation are main reasons for the growing popularity of Formal Concept Analysis (FCA). FCA gives the user the possibility to explore the structure of data and understand correlations and implications in the data set. Recently, triadic FCA (3FCA) has become increasingly popular, but exploring triadic conceptual landscapes is not easy, es...

The Affordable Care Act (ACA) has altered the healthcare landscape in the US. ACA mandated US residents to obtain health insurance. However, having insurance does not necessarily provide access to healthcare. These legislation changes made it imperative for researchers to explore into more detail the problem of healthcare accessibility. Recent advances in measuring healthcare accessibility have...
