The Grid is evolving and new concepts like Semantic Grid, Knwoledge Grid are rapidly emerging, where humans and distributed machines share, exchange, and manage data and resources intelligently. Computational scientists typically use workflows to describe and manage scientific discovery processes. However, the credibility of the obtained results in the scientific community is questionable if the computational experiment is not reproducible. This issue is being addressed in our research reported in this paper via development of workflow provenance system for Grid-enabled scientific workflows. Workflow provenance collects data on workflow activities, data flow and workflow clients. Provenance information can be used to trace and test workflows and the data produced. Our approach supports reproducibility (i.e. to support re-enactment of workflow by an independent user) and dataflow visualization (i.e. visualization of statistical characteristics of input/output data). We illustrate our approach on the Non-Invasive Glucose Measurement (NIGM) application.

knowledge graphs (KGs) are typically used to enhance the performance of recommender systems by leveraging their characteristic to supplement the sparse user-item interaction data in the latter. This is because KGs feature abundant semantic information about entities (e.g. users or items in recommender systems) and inter-entity relationships. Deep learning has been seen gain wide use in boosting the performance of recommender systems. Thanks to focusing merely on nodes in a KG, or entities, such an approach, however, suffers from well capturing the semantics hidden in the node connectivity when learning node embeddings, leading to undesirable discovery of potential semantic associations between nodes. Against this background, we propose for recommender systems a multi-level cross-view contrastive learning mechanism that learns high-quality feature representations from unlabeled data. By incorporating item-item correlations into item embeddings, we developed an interitem semantic association graph (SAG), which was intended to model more comprehensive and finer-grained inter-item semantic associations. A series of experiments have been carried out and the findings verify that the proposed mechanism outperforms other baseline models on all metrics, confirming the effectiveness of coupling SAGs with contrastive learning in enhancing the performance of recommender systems.

The venue of WETICE 2012 (the 21st WETICE) is Toulouse, France, with Professor Michel Diaz of LAAS-CNRS and Professor Patrick Senac of ISAE, ENSICA, both from Toulouse, France, as the General Co-Chairs. WETICE 2012 consists of 12 tracks of which 8 are ongoing tracks from previous years and 4 are new: 1) ACEC: Adaptive computing (and Agents) for Enhanced Collaboration (tenth year). 2) AROSA: Adaptive and Reconfigurable Service-Oriented and Component-Based Applications and Architectures (second year). 3) CDCGM: Convergence of distributed Cloud, Grids, and Their Management (second year). 4) CKDD: Cooperative knowledgediscovery and Data Mining( third year). 5) CoMetS: Collaborative Modeling and Simulation (third year). 6).. COPECH: Collaboration Tools for Preservation of Environment and Cultural Heritage (third year). 7) CPS: cyber Physical Society with SOA, BPM, and Sensor Networks (second year). 8) CT2CM: Collaborative Technology for Coordinating Crisis Management (second year). 9) CAGing: Collaborative and Autonomic Green computing (new). 10) MADYNE: Management of Dynamic Networked Enterprises (new). 11) CSP: Collaborative Software Processes (new). 12) Web2Touch: Modeling the Collaborative Web knowledge (new). A total of 132 papers were submitted to the tracks, of which 70 were accepted as full papers (53% acceptance) and 17 as short papers. You will also find the summary reports from each track in the proceedings written by the track chairs/organizers. The authors of the accepted papers are from 26 different countries around the world, thus keeping with the tradition of the international nature of WETICE.
