Video pollution on the Web
First Monday onder meer over: Video pollution on the Web.
"Videos have become a predominant part of users’ daily lives on the Web, especially with the emergence of video sharing services, such as YouTube. Part of the huge success of multimedia content in the Web is due to the change on the user perspective from content consumer to content creator. However, by allowing users to publicize their independently generated content, video sharing networks become susceptible to different types of pollution. As example, users can pollute the system spreading video messages containing undesirable content. Users can also associate metadata with videos in attempt to fool video search engines (i.e., popular tags, but unrelated to the content). Moreover, users can upload identical videos, generating duplicates of the same content on the system. Such pollution compromises not only the user satisfaction, but it also consumes system resources and can impact negatively aspects related to infrastructure. In this work we provide a general overview of pollution in video sharing systems. We define the different kinds of existent pollution, their negative impact to users and system and possible strategies to minimize the problem".

Data, data everywhere
The Economist met een special issue over het managen van data, getiteld "Data, data everywhere".
"All these examples tell the same story: that the world contains an unimaginably vast amount of digital information which is getting ever vaster ever more rapidly. This makes it possible to do many things that previously could not be done: spot business trends, prevent diseases, combat crime and so on. Managed well, the data can be used to unlock new sources of economic value, provide fresh insights into science and hold governments to account".
"But they are also creating a host of new problems. Despite the abundance of tools to capture, process and share all this information—sensors, computers, mobile phones and the like—it already exceeds the available storage space. Moreover, ensuring data security and protecting privacy is becoming harder as the information multiplies and is shared ever more widely around the world".
Artikelen:
* Data deluge. Businesses, governments and society are only starting to tap its vast potential.
* All too much. Monstrous amounts of data.
*A different game. Information is transforming traditional businesses.
* Clicking for gold. How internet companies profit from data on the web.
The open society. Governments are letting in the light
* Show me. New ways of visualising data
* Needle in a haystack. The uses of information about information.
*New rules for big data. Regulators are having to rethink their brief
* Handling the cornucopia. The best way to deal with all that information is to use machines. But they need watching.

Hoe meer, hoe minder
Hoe groter de beschikbaarheid van wetenschappelijke informatie, hoe minder de wetenschapper er gebruik van maakt. Daarnaast verwijst die zelfde wetenschapper meer en meer naar recente onderzoeken. Aldus, de socioloog James Evans van de University of Chicago, in zijn artikel "Electronic Publication and the Narrowing of Science and Scholarship" (Science, 18 Juli 2008, Vol. 321. no. 5887, pp. 395 - 399). Hierin stelt hij:
"I show that as more journal issues came online, the articles referenced tended to be more recent, fewer journals and articles were cited, and more of those citations were to fewer journals and articles".
Hier is het laatste woord nog niet over gezegd. Information Research maakt vast een beginnetje.

Inbox hulp
We worden overspoeld met emails. Inboxes barsten uit hun voegen. Deels als gevolg van wat sommigen "colleague spam" noemen (veel te vaak wordt bijvoorbeeld zonder te discrimineren de "reply to all" optie gebruikt), deels ook door de opkomst van sociale -en zakelijke netwerksites als Hyves, Facebook of LinkedIn.
Nieuwe initiatieven om deze overload te lijf te gaan zijn er genoeg. ClearContext en Seriosity buigen zich met name over de interne mail, terwijl Xobni de mail beter helpt te organiseren en doorzoekbaar te maken.
Sinds twee weken is Xobni ("it's inbox backwards") onderdeel van mijn Outlook. Het aantal mails dat elke dag mijn inbox insluipt vermindert hiermee niet, maar de mails zijn makkelijker terug te vinden, alsook adressen en attachments. In combinatie met de Copernic Desktop Search kom je dan een heel eind. Voorlopig :-(
