Consuming Linked Data

Sunday, October 23rd - 09:00-18:00 - Room: Reger

The quantity of published Linked Data is increasing dramatically. However, applications that consume Linked Data are not yet widespread. Current approaches lack methods for seamless integration of Linked Data from multiple sources, dynamic discovery of available data and data sources, provenance and information quality assessment, application development environments, and appropriate end user interfaces. Addressing these issues requires well-founded research, including the development and investigation of concepts that can be applied in systems which consume Linked Data from the Web. Following the success of the 1st International Workshop on Consuming Linked Data, we organize the second edition of this workshop in order to provide a platform for discussion and work on these open research problems. The main objective is to provide a venue for scientific discourse — including systematic analysis and rigorous evaluation — of concepts, algorithms and approaches for consuming Linked Data.

Detection, Representation, and Exploitation of Events in the Semantic Web

Sunday, October 23rd - 09:00-18:00 - Room: Koch

In recent years, researchers in several communities involved in aspects of the web have begun to realise the potential benefits of assigning an important role to events in the representation and organisation of knowledge and media. The goal of this workshop is to advance research on this general topic within the semantic web community, focusing on topics such as detection and extraction of events, modeling and representation of events, and the use of events within applications, including visualization and interaction. Prior to the workshop, a dataset containing linked events will be made available and a prize is awarded to those participants that submit the best application/analysis based on this data.

Knowledge Evolution and Ontology Dynamics

Monday, October 24th - 09:00 - 18:00 - Room: Koenig

EvoDyn builds on the success of the previous editions of the Ontology Dynamics workshop formerly known as IWOD (organised as a part of the ESWC'07, ISWC'08, ISWC'09 and ISWC'10 conferences). EvoDyn continues in the tradition of IWOD in being the core annual event to discuss advances in the broad area of ontology dynamics, and to track recent work directly or indirectly related to the problem of evolving ontologies. This year, however, the scope of the workshop is broadened by a special focus on the knowledge evolution. In particular, the workshop focuses on analysis of trends and change in formal descriptions (i.e., ontologies), but also in associated raw sources of knowledge (scientific publications, unstructured or semi-structured web content, traditional data stores, e-mail or on-line discussion threads, etc.). We are especially interested in research targeted on various states of knowledge evolution, such as (a) conflicts, (b) consolidation, (c) discovery, (d) paradigm shifts, and (e) breakthroughs. One crucial objective of better understanding these different states may be to study directly the underlying causes and dynamics needed to generate discoveries and breakthroughs. We will only be able to facilitate and possibly also generate such desirable situations if we can understand the process of how knowledge evolves. The process of how knowledge in a field grows and changes, crystallizes, and fractures are all areas of interest of this workshop.

Linked Science

Monday, October 24th - 09:00-18:00 - Room: Koch

Scientific efforts are traditionally published only as articles, with an estimate of millions of publications worldwide per year; the growth rate of PubMed alone is now 1 papers per minute. The validation of scientific results requires reproducible methods, which can only be achieved if the same data, processes, and algorithms as those used in the original experiments were available. However, the problem is that although publications, methods and datasets are very related, they are not always openly accessible and interlinked. Even where data is discoverable, accessible and assessable, significant challenges remain in the reuse of the data, in particular facilitating the necessary correlation, integration and synthesis of data across levels of theory, techniques and disciplines. In the 1st International Workshop on Linked Science (LISC 2011) we will discuss and present results of new ways of publishing, sharing, linking, and analyzing such scientific resources motivated by driving scientific requirements, as well as reasoning over the data to discover interesting new links and scientific insights.

The Multilingual Semantic Web

Sunday, October 23 - 09:00 - 18:00 - Room: Lenné

Multilingualism has become an issue of major interest for the Semantic Web community, in light of the substantial growth of internet users that create and update knowledge all over the world in languages other than English. This process has been accelerated due to initiatives such as the Linked Data initiative, which encourages not only governments and public institutes to make their data available to the public, but also private organizations in domains as far apart as medicine, cartography or music. These actors publish their data sources in the languages they are available in, and as such, in order to make this information available to an international community, multilingual knowledge representation, access and translation are an impending need. Building on the success of the first edition of this workshop, we have organized a second workshop focusing on topics such as the representation of multilingual information in the Semantic Web, cross-lingual querying, multilingual mapping, machine translation, and localization strategies for the Semantic Web.

Ontologies come of Age in the Semantic Web

Monday, October 24th - 09:00 - 12:30 - Room: Mann

The real challenge for Semantic Web technologies and ontologies lays in the adoption; although the need for this disruptive technology is clear, it has not yet been fully adopted by the mainstream. Ontologies: where, what for, how, when and why? Ontologies are being used in several applications, but is ontology engineering a mature discipline? Not only are we interested in practical realizations of the Semantic Web, but also in visions of technology that illustrate how SW technology and ontologies could change our experience of the Web.

Ontology Matching

Monday, October 24th - 09:00 - 18:00 - Room: Reger

Ontology matching is a key interoperability enabler for the Semantic Web, as well as a useful tactic in some classical data integration tasks dealing with the semantic heterogeneity problem. It takes the ontologies as input and determines as output an alignment, that is, a set of correspondences between the semantically related entities of those ontologies. These correspondences can be used for various tasks, such as ontology merging, data translation, query answering or navigation on the web of data. Thus, matching ontologies enables the knowledge and data expressed in the matched ontologies to interoperate. The workshop has three goals:

  • To bring together leaders from , and institutions to assess how academic advances are addressing real-world requirements. The workshop will strive to improve academic awareness of industrial and final user needs, and therefore direct research towards those needs. Simultaneously, the workshop will serve to inform industry and user representatives about existing research efforts that may meet their requirements. The workshop will also investigate how the ontology matching technology is going to evolve.

  • To conduct an extensive and rigorous evaluation of ontology matching approaches through the OAEI (Ontology Alignment Evaluation Initiative) 2011 campaign. The particular focus of this year's OAEI campaign is on real-world specific matching tasks involving, e.g., open linked data and biomedical ontologies. Therefore, the ontology matching evaluation initiative itself will provide a solid ground for discussion of how well the current approaches are meeting business needs.

  • To examine similarities and differences from database schema matching, which has received decades of attention but is just beginning to transition to mainstream tools.

Semantic Personalized Information Management: Retrieval and Recommendation

Monday, October 24th - 09:00 - 18:00 - Room: Lenné

Search engines implementing the canonical search paradigm are adequate for most ad-hoc keyword-based search tasks, but they reach limits when user needs have to be satisfied in a personalized way. With the advent of the Semantic Web, new opportunities emerge for semantic information retrieval systems to better match user needs. Next generation search engines should implement a novel search paradigm, where the user perspective is completely reversed: from finding to being found. Recommender Systems may help to support this new perspective, because they have the effect of pushing relevant objects to potentially interested users. An emerging approach is to use Semantic Web technologies to model information about users, their needs and preferences, their context and relations, and to incorporate data from other resources like Linked Open Data. The aim of the workshop is to investigate whether and how this large amount of wide-coverage and linked semantic knowledge can significantly improve the search/recommendation process in those tasks that cannot be solved merely through a straightforward matching of queries and documents.

Social Data on the Web

Sunday, October 23rd - 09:00 - 18:00 - Room: Einstein

The 4th international workshop on Social Data on the Web (SDoW2011) aims to bring together researchers, developers and practitioners involved in semantically-enhancing social media websites, as well as academics researching more formal aspect of these interactions between the Semantic Web and Social Web, including people involved in recent active developments in collaborative and social software and their Semantic Web counterparts, notably in the industry, such as Facebook Open Graph Protocol. It is now widely agreed in the community that the Semantic Web and the Social Web can benefit from each other. One the one hand, the speed at which data is being created on the Social Web is growing at exponential rate. Recent statistics showed that about 100 million Tweets are created per day and that Facebook has now 500 million users. Yet, some issues still have to be tackled, such as how to efficiently make sense of all this data, how to ensure trust and privacy on the Social Web, how to interlink data from different systems, whether it is on the Web or in the enterprise, or more recently, how to link Social Network and sensor networks to enable Semantic Citizen Sensing. Following the successful SDoW workshops at ISWC 2008, 2009 and 2010, this workshop will tackle these various topics and aims at bringing together researchers and practitioners, as in the 3 previous editions.

Terra Cognita - Foundations, Technologies and Applications of the Geospatial Web

Sunday, October 23rd - 09:00 - 18:00 - Room: Koenig

The wide availability of technologies such as GPS, map services and social networks, has resulted in the proliferation of geospatial data on the Web. Researchers have been quick to realize the importance of this development and have started working on the relevant research problems, giving rise to new topical research areas such as “Geographic Information Retrieval”, “Geospatial (Semantic) Web”, “Linked Geospatial Data” and “GeoWeb 2.0”. Similarly, standardization bodies such as the Open Geospatial Consortium (OGC) have been developing relevant standards such as the Geography Markup Language (GML) and GeoSPARQL.
The goal of this workshop is to bring together researchers and practitioners from related disciplines, as well as interested parties from industry and government, to advance the frontiers of this exciting research area.

Web Scale Knowledge Extraction

Monday, October 24th - 14:00 - 18:00 - Room: Haber

There has been a significant amount of interest recently in automatically creating large-scale knowledge bases from unstructured text. Compared to traditional, manually created representations, these knowledge bases have the advantage of scale and coverage. They often contain tens of millions of propositions, represented using a variety of encodings, from simple binary assertions to more complicated frame-like structures, and are extracted by parsing and analyzing large text corpora. This workshop is designed to gather researchers in the area of building and applying textually mined knowledge bases and to discuss key related issues and applications.
