Information integration and consciousness are closely related, if not interdependent. But, what exactly is the nature of their relation? Which forms of integration require consciousness? Here, we examine the recent experimental literature with respect to perceptual and cognitive integration of spatiotemporal, multisensory, semantic, and novel information. We suggest that, whereas some integrati...

In this paper we consider a novel information-theoretic approach to multiple kernel learning based on minimising a Kullback-Leibler (KL) divergence between the output kernel matrix and the input kernel matrix. There are two formulations which we refer to as MKLdiv-dc and MKLdiv-conv. We propose to solve MKLdiv-dc by a difference of convex (DC) programming method and MKLdivconv by a projected gr...

The integration of information of different kinds, such as spatial and alphanumeric, at different levels of detail is a challenge. While a solution is not reached, it is widely recognized that the need to integrate information is so pressing that it does not matter if detail is lost, as long as integration is achieved. This paper shows the potential for extraction of different levels of informa...

One of the most fundamental subtasks of information integration which comes up very often in day-to-day business and research is the publishing of documents, e.g. project plans, business reports, presentation layers, product designs, idea sketches, announcements, telephone lists, reports, advertisements or research papers. Actually, over 90% of companies knowledge is according to a study of the...

Grid computing [3] constitutes the amalgamation of a drive towards the standardization of existing technologies that enable the collaboration of scientists overcoming restrictions of location, distance and compatibility. The aim is to exploit the full potential of resources, computational or informational. We aim to study how a network of distributed and heterogeneous grid resources could attai...

Information geometry is used to quantify the amount of information integration within multiple terminals of a causal dynamical system. Integrated information quantifies how much information is lost when a system is split into parts and information transmission between the parts is removed. Multiple measures have been proposed as a measure of integrated information. Here, we analyze four of the ...

This paper suggests a new approach to improve the integration of information. This approach is based on the use of semantic adaptive graphs. The adaptive feature of our proposal makes it possible to manage two specific aspects related to information integration: the adaptation of information according to the user’s access rights and the lifecycle of the integrated information.

To utilize the full potential of structured or semi-structured data stored across different information systems, users and applications must not be confronted directly with the individual, heterogeneous data sources, but instead be supplied with a customized integrated view on the data. Traditional information integration is relying on a human-driven process to accomplish this task. While feasi...

This thesis describes the design and the implementation of a wrapper engine to query semi-structured remote data sources for the Context Interchange group. Research is focused on the continued development of the query execution engine, and the design and implementation of a planner to structure and optimize user queries. Major problems dealt with include the automatic extraction of data, manipu...
