Formal concept analysis in knowledge discovery: a survey

In this paper, we analyze the literature on Formal Concept Analysis (FCA) using FCA. We collected 702 papers published between 2003-2009 mentioning Formal Concept Analysis in the abstract. We developed a knowledge browsing environment to support our literature analysis process. The pdf-files containing the papers were converted to plain text and in...

Terrorist threat assessment with formal concept analysis

The National Police Service Agency of the Netherlands developed a model to classify (potential) jihadists in four sequential phases of radicalism. The goal of the model is to signal the potential jihadist as early as possible to prevent him or her to enter the next phase. This model has up till now, never been used to actively find new subjects. In...

Beyond genes, proteins, and abstracts: Identifying scientific claims from full-text biomedical articles.

Published in Journal of biomedical informatics

Massive increases in electronically available text have spurred a variety of natural language processing methods to automatically identify relationships from text; however, existing annotated collections comprise only bioinformatics (gene-protein) or clinical informatics (treatment-disease) relationships. This paper introduces the Claim Framework t...

Une approche générique pour l'analyse croisant contenu et usage des sites Web par des méthodes de bipartitionnement

Dans cette thèse, nous proposons une nouvelle approche WCUM (Web Content and Usage Mining based approach) permettant de relier l'analyse du contenu à l'analyse de l'usage d'un site Web afin de mieux comprendre le comportement général des visiteurs du site. Ce travail repose sur l'utilisation de l'algorithme CROKI2 de classification croisée implémen...

BioPPISVMExtractor: a protein-protein interaction extractor for biomedical literature using SVM and rich feature sets.

Published in Journal of biomedical informatics

Protein-protein interactions play a key role in various aspects of the structural and functional organization of the cell. Knowledge about them unveils the molecular mechanisms of biological processes. However, the amount of biomedical literature regarding protein interactions is increasing rapidly and it is difficult for interaction database curat...

Exploring the feasability and accuracy of Latent Semantic Analysis based text mining techniques to detect similarity bet...

In this study, we examine and validate the use of existing text mining techniques (based on the vector space model and latent semantic indexing) to detect similarities between patent documents and scientific publications. Clearly, experts involved in domain studies would benefit from techniques that allow similarity to be detected—and hence facilit...

WCUM pour l'analyse d'un site Web

La caractérisation des internautes fréquentant un site Web est un problème incontournable pour assister l'internaute et prédire son comportement. Ces considérations ont motivé d'importants efforts dans l'analyse des traces des internautes sur les sites Web. D'autres efforts ont été concentrés sur l'analyse du contenu des pages Web. Sachant que le c...

Textual data mining applications for industrial knowledge management solutions

In recent years knowledge has become an important resource to enhance the business and many activities are required to manage these knowledge resources well and help companies to remain competitive within industrial environments. The data available in most industrial setups is complex in nature and multiple different data formats may be generated t...
