1. Product/Brand extraction from WikiPedia

Author

Subjects

Abstract

In this paper we describe the task of extracting product and brand pages from wikipedia. We present an experimental environment and setup built on top of a dataset of wikipedia pages we collected. We introduce a method for recognition of product pages modelled as a boolean probabilistic classification task. We show that this approach can lead to promising results and we discuss alternative approaches we considered., Comment: 17 pages. Manuscript first creation date: November 27, 2009. At the time of first creation both authors were affiliated with the University of Amsterdam (The Netherlands)

Abstract

An analysis of the physical properties of peroxometal complexes containing ligands reveals that the IR O bond O bond frequency of the complexes is responsible for their ability to act as single electron acceptors. The correlation is valid for different metals with the same ligand and a single metal with different ligands. The various coordinate spheres of a metal's derivatives determine its oxidation chemistries. The O bond O strength controls the reduction potential of the oxometal species.

Abstract

In this paper we present an unsupervised learning approach to detect meaningful job traffic patterns in Grid log data. Manual anomaly detection on modern Grid environments is troublesome given their increasing complexity, the distributed, dynamic topology of the network and heterogeneity of the jobs being executed. The ability to automatically detect meaningful events with little or no human intervention is therefore desirable. We evaluate our method on a set of log data collected on the Grid. Since we lack a priori knowledge of patterns that can be detected and no labelled data is available, an unsupervised learning method is followed. We cluster jobs executed on the Grid using Affinity Propagation. We try to explain discovered clusters using representative features and we label them with the help of domain experts. Finally, as a further validation step, we construct a classifier for five of the detected clusters and we use it to predict the termination status of unseen jobs.
