Web-Scale Extension of RDF Knowledge Bases from Templated Websites [chapter]

Lorenz Bühmann, Ricardo Usbeck, Axel-Cyrille Ngonga Ngomo, Muhammad Saleem, Andreas Both, Valter Crescenzi, Paolo Merialdo, Disheng Qiu
2014 Lecture Notes in Computer Science  
In this paper, we present a holistic and open-source framework for the extraction of RDF from templated websites.  ...  While converting structured data to RDF is well supported by tools, most approaches to extract RDF from semi-structured data rely on extraction methods based on ad-hoc solutions.  ...  REX addresses the extraction of RDF from templated websites by providing a modular and extensible architecture for learning XPath wrappers and extracting consistent RDF data from these web pages.  ...

Balloon Synopsis: A Modern Node-Centric RDF Viewer and Browser for the Web [chapter]

Kai Schlegel, Thomas Weißgerber, Florian Stegmaier, Christin Seifert, Michael Granitzer, Harald Kosch
2014 Lecture Notes in Computer Science  
Nowadays, the RDF data model is a crucial part of the Semantic Web. Especially web developers favour RDF serialization formats like RDFa and JSON-LD.  ...  However, the visualization of large portions of RDF data in an appealing way is still a cumbersome task.  ...  Balloon Synopsis was developed to allow Web developers an easy-to-use and embeddable RDF visualization for their website, enabling simple access and re-use of Linked Data.  ...

Effective web scraping with OXPath

Giovanni Grasso, Tim Furche, Christian Schallhart
2013 Proceedings of the 22nd International Conference on World Wide Web - WWW '13 Companion  
Even in the third decade of the Web, scraping web sites remains a challenging task: Most scraping programs are still developed as ad-hoc solutions using a complex stack of languages and tools.  ...  In this presentation, we want to introduce you to a new paradigm of scraping: declarative navigation-instead of complex scripting or heavyweight, limited visual tools, OXPath turns scraping into a simple  ...  The idea is to use a knowledge base of known web applications (e.g., vBullettin, Word-Press) and their publishing templates, in order to archive only valuable information (e.g., posts, authors, comments  ...

SWoTSuite: A Development Framework for Prototyping Cross-domain Semantic Web of Things Applications [article]

Pankesh Patel, Amelie Gyrard, Dhavalkumar Thakker, Amit Sheth, Martin Serrano
2016 arXiv   pre-print
Semantic Web of Things (SWoT) applications focus on providing a wide-scale interoperability that allows the sharing of IoT devices across domains and the reusing of available knowledge on the web.  ...  It hides the use of semantic web technologies as much as possible to avoid the burden of designing SWoT applications that involves designing ontologies, annotating sensor data, and using reasoning mechanisms  ...  Taking inspiration from Content Management Systems (e.g., Drupal, Wordpress) that enables a design of websites without learning web technologies, we reduce the gap of learning semantic web technologies  ...
