How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Chapter
This work deepens in a methodology to generate Instance Level Constraints for Semi-supervised clustering by the study of the inherent nature of the data. The methodology executes a partitional clustering algorithm repetitively, so we study its behaviour according to the number of iterations of the clustering. In this scenario we propose three diffe...

Full-text available
In the last times, semi-supervised clustering has been an area that has received a lot of attention. It is distinguished from more traditional unsupervised approaches on the use of a small amount of supervision to “steer” clustering. Unfortunately in the real world, the supervision is not always available: data to process are often too large and so...
Article
This paper introduces Fuzzy HSS, a semisupervised hierarchical clustering approach that uses fuzzy instance-level constraints. These constraints are external information on the shape of fuzzy must-link and fuzzy cannot-link restrictions. They allow uncertainty when indicating whether two instances of a dataset belong to the same group. Fuzzy must-l...
Conference Paper
This paper introduces a new method of fuzzy semisupervised hierarchical clustering using fuzzy instance level constraints. It introduces the concepts of fuzzy must-link and fuzzy cannot-link constraints and use them to find the optimum α-cut of a dendrogram. This method is used to approach the problem of classifying scientific publications in web d...
Article
In this paper we introduce an automatic system to perform authority control in digital libraries based on data mining techniques. This system is able to find the different representations for an author name as well as to distinguish between different authors sharing the same name. Using that information, the system shows the user the results of a s...

This paper introduces a new semisupervised fuzzy algorithm that makes use of must-link and cannot-link constraints. These constraints are applied to the process of finding the optimum α-cut of a dendrogram. We have applied this method to identity identification in digital libraries.
Conference Paper
In this paper we present an automatic authority control system for raw noisy web data based on Data Mining. We use a hierarchical clustering approach with a special distance measure combination of three parameters: author name similarity, token similarity and co-authors similarity, each one defined in a specific way. A preliminary experimental stud...
