Topic Maps and the Semantic Web

by , Category: Conferences & Events, Miscellaneous, Tools & Software

tmraFrom November 11 – 13, 2009 this will be one of the big issues at the 5th International Conference on Topic Maps taking place in Leipzig/Germany. When asked about the relationship between TM and SemWeb conference organizer Lutz Maicher says:

With the vision of the web of data Topic Maps and the Semantic Web move closer over time. Anywhere URIs represent subjects, structured statements are gathered around them. In this context I see subj3ct.com as an interesting ventures. This recently launched service provides URIs for 15 million subjects to be used in structured data. Naturally, linked data hubs like dbpedia or geonames.org are part of it. The crowd is invited to contribute to this collection, also the Topic Maps Lab provides several feeds to register new URIs. Subj3ct.com turns out to be an infrastructure technology for Web 3.0 applications, regardless whether they are based on Topic Maps or other Semantic Web technologies.

Through this convergence the uniqueness of each technology sharpens. Reasoning is the strong point of the Semantic Web. But the strength of Topic Maps are semantic portals and the global federation of facts around subjects. Bringing together all and even contradictory information about each subject – and not building reasoning-ready consistent models of the world – is built into the genes of Topic Maps.

Chris Bizer talks about the commercial opportunities of linked data

bizerIn a recent interview Prof. Chris Bizer from FU Berlin gave some insights into the commercial opportunities of linked data. In the short run he predicts three application areas:

I think we will see a growing number of applications that use data from the public Web as background knowledge to offer better search capabilities and to augment local content with additional content from the Web of Data.
[...]
Beside of the classic search engines, there might also be market opportunities for new search engines that specialize on Linked Data. [...] This will allow them to sell access to cleaned views on the Data Web and to become central components within Linked Data applications.
[...]
Within the corporate market, there is interest in using Linked Data as a lightweight, pay-as-you-go data integration technology.

Additionally Chris comments on the latest developments in the area of triple stores and D2RQ, and the necessity for more privacy awareness and information accountability in an increasingly interlinked world.

The Times They Are A-Changin … yes, we can

President Obama

One of the many ways that the election of Barack Obama as president has echoed that of John F. Kennedy is his use of a new medium that will forever change politics. For Mr. Kennedy, it was television. For Mr. Obama, it is the Internet. Obama´s Internet Campaign Changed Politics. “Were it not for the Internet, Barack Obama would not be president. Were it not for the Internet, Barack Obama would not have been the nominee,” said Arianna Huffington, editor in chief of The Huffington Post.

America´s new president Barack Obama didn’t go out and recruit on facebook, they came to him at first. Did the internet make Obama’s natural “viralness” quicker and more transparent? Obama’s huge victory on Tuesday night was celebrated in Austria and Germany, as it was around the world: German Press on Obama Victory: “The Dream is Alive“. Der Spiegel‘s Gabor Steingart – who for months dismissed the notion that Obama had a real chance for the White House – writes about the Resurrection of the American Dream: “His base note is conciliatory, his overtone is exalted and the harmony is finely balanced. If anyone out there still doubted that the American dream was alive, he called out to his supporters in Chicago, “tonight is your answer.”

However things will happen or not and however the „Change has come to America“: The president´s new official website is online www.whitehouse.gov. And here users are really being involved. We all are involved. Obama means change. Let´s see in what ways this will concern the future of the internet.

Read this: Linking Social Networks on the Web with FOAF

ABSTRACT
One of the core goals of the Semantic Web is to store data in distributed locations, and use ontologies and reasoning to aggregate it. Social networking is a large movement on the web, and social networking data using the Friend of a Friend (FOAF) vocabulary makes up a significant portion of all data on the Semantic Web. Many traditional webbased social networks share their members’ information in FOAF format. While this is by far the largest source of FOAF online, there is no information about whether the social network models from each network overlap to create a larger unified social network model, or whether they are simply isolated components. In this paper, we present a study of the intersection of FOAF data found in many online social networks. Using the semantics of the FOAF ontology and applying Semantic Web reasoning techniques, we show that a significant percentage of profiles can be merged from
multiple networks. We present results on how this affects network structure and what it says about relationships and individual behavior. Finally, we discuss the implications this has for using web-based social networking data to create intelligent user interfaces and social software.
