Formal Concept Analysis (FCA) and concept lattices have shown their effectiveness for binary clustering and concept learning. Moreover, several links between FCA and unsupervised data mining tasks such as itemset mining and association rules extraction have been emphasized. Several works also studied FCA in a supervised framework, showing that popular machine learning tools such as decision tre...

Inferring biotic interactions from functional, phylogenetic and geographical proxies remains one great challenge in ecology. We propose a conceptual framework to infer the backbone of biotic interaction networks within regional species pools. First, interacting groups are identified to order links and remove forbidden interactions between species. Second, additional links are removed by examina...

We describe the GOHSE system, an application to support browsing of biology resources. The Conceptual Open Hypermedia Service (COHSE) system enhances web resources through the dynamic addition of hypertext links. These links are derived through the use of an ontology and associated lexicon along with a mapping from concepts to possible link targets. GOHSE applies COHSE to Bioinformatics, using ...

In this chapter, we review several strands of research that share one common theme: the close conceptual and empirical links between categorization and recognition memory. We demonstrate that these links are strong, and often surprising. We explore the relation between recognition and unsupervised learning, and we investigate how perceptual processes can provide a unifying link between categori...

This note describes a scoring scheme for the coreference task in MUC6 . It improves o n the original approach l by: (1) grounding the scoring scheme in terms of a model ; (2) producing more intuitive recall and precision scores ; and (3) not requiring explici t computation of the transitive closure of coreference . The principal conceptual differenc e is that we have moved from a syntactic scor...

This paper offers an overview for a special issue on agroindustrialization, globalization, and international development. It out a conceptual framework for understanding the links among these three broad phenomena and then discusses emerging issues and evidence concerning the factors conditioning agroindustrialization in developing countries and the subsequent effects on employment, poverty, an...

A new architecture for autonomous agents is proposed. The architecture integrates the symbolic and and the behavioral processing of data coming from the robot sensors. The integration is based on the introduction of a conceptual space representation that links the subconceptual level, which is a repository of behavioral modules, with the symbolic level, in which rich symbolic descriptions of th...

Recent distributed systems, in a P2P scenario, are characterized by a set of independent peers that dynamically need to cooperate by sharing data and services. For effective collaboration, under highly dynamic conditions and in absence of a global view of the resources shared across the information systems, semantic modeling tools need be defined. In particular, the emergence of semantics is a ...

The practice of setting quantum fields as sources for classical general relativity is examined. Several conceptual problems are identified which invalidate apparently innocuous equations. Alternative ways to links classical general relativity with quantum theory using Bohm’s theory are proposed. PACS numbers: 12.90.+b, 03.65.Ta, 04.20.Cv Submitted to: Class. Quantum Grav. Quantum fields as grav...
