Keyword advertising, or “sponsored links” that appear alongside online search results or other online content, has grown into a multibillion-dollar market. Providers of keyword advertising, such as Google and Yahoo, profit by auctioning keywords to advertisers. An issue of increasing importance for advertising providers is the “share structure” problem—that is, of the total available resources ...

In this paper we introduce a minimalist hypothesis for keywords extraction: keywords can be extracted from text documents by considering concepts underlying document terms. Furthermore, central concepts are individuated as the concepts that are more related to title concepts. Namely, we propose five metrics, that are diverse in essence, to compute the centrality of concepts in the document body...

•Extending our previous work on visual keywords, we use the concept of template-based visual keywords using MPEG-7 color descriptors. MPEG-7, also called the Multimedia Content Description Interface, has been a standard for many years. These color descriptors have the ability to characterize perceptual color similarity and need relatively low complexity operations to extract them, besides being...

The pharmaceutical area can present some opportunities for mechanical engineers to develop a vast type of dosage forms particularly novel forms like nanoparticles. The classical education of mechanics needs some alterations to prepare appropriate education courses in this regard. In order to present some views about this issue, we collect some information around the importance of mechanical eng...

Supply network management adopts a systematic and integrative approach to managing the operations and relationships of various parties in a supply network. The objective of the manufactures in their supply network is to reduce inventory costs and increase customer satisfaction levels. One way of doing that is to synchronize delivery performance. A supply network can be described by nodes repres...

In the current Internet, more and more providers are developing and deploying their own Content Delivery Networks in order to improve the Quality of Experience and decrease the load within their networks. An interesting scenario would be to interconnect these networks to cooperate between these different Content Delivery Networks. The IETF Content Delivery Network Interconnection Working Group ...
