The shift towards global networking brings with it many opportunities and challenges. In this paper, we discuss key technologies in achieving global semantic interoperability among heterogeneous information systems, including both traditional and web data sources. In particular, we focus on…

Most of the search engines available over the Web are based on mathematical approaches | classical techniques in the Information Retrieval area. Thereby, they are suitable for the retrieval of documents containing some or all the terms of a query,…

We address the problem of integrating objects from a source taxonomy into a master taxonomy. This problem is not only pervasive on the nowadays web, but also important to the emerging semantic web. A straightforward approach to automating this process…

Understanding the biological signals encoded in a genome is a key challenge of computational biology. These signals are encoded in the four-nucleotide alphabet of DNA and are responsible for all molecular processes in the cell. In particular, the genome contains…

Ensuring environmental sustainability is the aim of the seventh Millennium Development Goal (MDG7). United Nations data shows insufficient progress, especially in developing countries. In order to generate new information about this progress and the main barriers that hinder it, we…

Satellite and wireless networks operate over time varying channels that depend on attenuation conditions, power allocation decisions, and inter-channel interference. In order to reliably integrate these systems into a high speed data network and meet the increasing demand for high…

This paper evaluates the different tasks carried out in the translation of pronominal anaphora in a machine translation (MT) system. The MT interlingua approach named AGIR (Anaphora Generation with an Interlingua Representation) improves upon other proposals presented to date because…

For 20 years, and more intensively during the last decade, indigenous knowledge has challenged the regime of intellectual property. If this field of law has been, in the past, challenged by new technology, it is now, with the problematic of…

Intellectual capital, as opposed to traditional conceptions of intellectual property, is neither as simple to define nor as straightforward to protect and regulate. As companies in the financial services sector attempt the efficient management of increasingly voluminous and strategically important…

An indirect crisis, the terrorist attacks of September 1 1 , is used as a catalyst to review the tasks of the Nuclear Nonproliferation Regime. However, it is insufficient to initiate a comprehensive change to the regime to incorporate the…
