Clustering bipartite graphs in terms of approximate formal concepts and sub-contexts [PDF]

International Journal of Computational Intelligence Systems, 2013
The paper first offers a parallel between two approaches to conceptual clustering, namely formal concept analysis (augmented with the introduction of new operators) and bipartite graph analysis.

Graph Theoretic Lattice Mining Based on Formal Concept Analysis (FCA) Theory for Text Mining

International Journal on Advanced Science, Engineering and Information Technology, 2017
The growth of the semantic web has fueled the need to search for information based on the understanding of the intent of the searcher, coupled with the contextual meaning of the keywords supplied by the searcher. The common solution to enhance the searching process includes the deployment of formal concept analysis (FCA) theory to extract concepts from

ESG Measurement and Ratings Divergence: A Cross‐Jurisdictional Review of Institutional, Stakeholder, and Digital Accountability Perspectives

Business Strategy and the Environment, EarlyView.
ABSTRACT ESG ratings for the same firm‐year often diverge, shaping capital allocation and accountability. Drawing on a structured systematic‐narrative hybrid review, I synthesize evidence across the European Union, the United States, and China and develop a transnational accountability framework that traces divergence through the measurement pipeline ...

Simplifying Implications with Positive and Negative Attributes: A Logic-Based Approach

Mathematics, 2022
Concepts and implications are two facets of the knowledge contained within a binary relation between objects and attributes. Simplification logic (SL) has proved to be valuable for the study of attribute implications in a concept lattice, a topic of ...

Issue Construals and Corporate Water Stewardship

Business Strategy and the Environment, EarlyView.
ABSTRACT In the face of mounting environmental and social pressures, the importance of responsible corporate water stewardship (CWS) should be evident, yet not all businesses are taking water management issues seriously. The aim of this study is to explore why differences in CWS persist, especially within industries facing similar resource challenges ...

Board Gender Diversity and the Quality of Corporate Climate Impact Disclosure: UK Evidence

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines how board gender diversity influences the quality of corporate climate impact disclosure, a critical element of firms' environmental transparency. Focusing on UK nonfinancial firms, we draw on gender socialisation and critical mass theories to explore how diverse boards contribute to strategic climate reporting.

High‐throughput development and scale‐up of recombinant adeno‐associated virus 5 anion‐exchange chromatography for high‐purity capsid separation

Biotechnology Progress, EarlyView.
High‐throughput anion‐exchange chromatography process development enables scalable purification of high‐purity recombinant adeno‐associated virus capsids. Abstract Recombinant adeno‐associated virus (rAAV) production commonly yields a high proportion of empty and partially filled capsids, necessitating downstream purification to enrich full capsids ...
