In conjunction with the 22nd International World Wide Web Conference (WWW2013), Rio de Janeiro, 13 May 2013


The explosive growth in the amount of data created and shared on the “Web of Data” is now firmly established. However, the majority of the available Web content is still unstructured or semi-structured. As a general trend, unstructured data seems to be growing faster than structured data. According to a 2011 IDC study, unstructured data will account for 90 percent of all data created in the next decade. As the main goal of the Web of Data is to stimulate the emergence of new dedicated applications giving the machines ability to process information, there is a strong need to extract as far as possible structured data from unstructured content available on the web. Furthermore, structured data sources provide entity to entity interconnections, resulting in a Web of Linked Entities spanning structured and unstructured data. According to this, there is also a strong emergent need to study how to associate non structured content (like textual documents) and structured content (like RDF triples) with information retrieval, extraction, integration and exploration existing techniques. The WoLE workshop series envisions a Web of Linked Entities (WoLE), which transparently connects the World Wide Web (WWW) and the Giant Global Graph (GGG) using methods from Information Retrieval (IR), Natural Language Processing (NLP) and Database Systems (DB) research communities. The previous edition of WoLE workshop have shown that different methods involved in specific research tasks of those communities (like co-reference detection in NLP or information extraction in IR) can provide different ways to improve the web of Linked Entities content and its relation with unstructured documents. According to this, the primary goal of WoLE is to confront propositions from IR, NLP and DB research communities describing how their specific methods can improve quality of the Web data, structure its documents and help to explore its content.
