Heiko Stoermer, Nataliya Rassadko
Abstract. To investigate the problem of entity recognition, we deal with the creation of the so-called Entity Name System (ENS) which is an open, public back-bone infrastructure for the (Semantic)...
The Entity Name System: Enabling the Web of Entities (2010)
Heiko Stoermer, Themis Palpanas, George Giannakopoulos
Abstract — We are currently witnessing an increasing interest in the use of the web as an information and knowledge source. Much of the information sought after in the web is in this case relevant...
From Web Data to Entities and Back (2010)
Miklos, Zoltan, Bonvin, Nicolas, Bouquet, Paolo, Catasta, Michele, Cordioli, Daniele, Fankhauser, Peter, ...
We present the Entity Name System (ENS), an enabling infrastructure, which can host descriptions of named entities and provide unique identifiers, on large-scale. In this way, it opens new...
1144 CAiSE'06 Doctoral Consortium Introducing Context into Semantic Web Knowledge Bases (2009)
Abstract. Knowledge Representation in the Semantic Web is mainly characterized by the capabilities of the languages OWL and RDF. When attacking non-trivial problems such as the creation and...
LibSwb: Browsing the Entity Context ⋆ (2009)
Sven Buschbeck, Stefano Bortoli, Heiko Stoermer
Abstract. In this paper we are presenting ongoing work on a software library for on-the-fly browsing of Semantic Web content that forms the informational context around an entity. This library is...
Searching for Individual Entities: a Query Analysis (2009)
Bazzanella, Barbara, Stoermer, Heiko, Bouquet, Paolo
Searching for information about individual entities such as persons, locations, events, is an important activity in Internet search today, and is in its core a very semantic-oriented task. Several...
A Cognitive Contribution to Entity Representation and Matching (2009)
Bazzanella, Barbara, Bouquet, Paolo, Stoermer, Heiko
The problem of Data Linkage in the Semantic Web can be divided in two lines of action: schema and ontology matching/mapping, which allows us to draw conclusions about sets of individuals through...
RDF and Contexts: Use of SPARQL and Named Graphs to Achieve (2008)
Heiko Stoermer, Ignazio Palmisano, Domenico Redavid, Paolo Bouquet, Giovanni Semeraro
Abstract. The very simple structure of the RDF data model and semantics can lead to a number of issues when more complex scenarios are supposed to be represented in RDF. Aspects such as temporary...
Top Level Categories and Attributes for Entity Representation (2008)
Bazzanella, Barbara, Bouquet, Paolo, Stoermer, Heiko
In this document we present the results of an experiment that investigates how people represents different types of entities (Entity Identification Experiment). Using a feature-listing task paradigm...
Contextualization of a RDF Knowledge Base in the VIKEF Project (2008)
Heiko Stoermer, Ignazio Palmisano, Domenico Redavid, Paolo Bouquet, Giovanni Semeraro
Abstract. Due to the simplicity of RDF data model and semantics, complex application scenarios in which RDF is used to represent the application data model raise important design issues. Modelling...
Achieving Scalability and Expressivity in an RDF Knowledge Base by Implementing Contexts (2008)
Abstract — In this paper we are presenting the context architecture implemented on top of the RDFCore system. With this extended Knowledge Representation framework we are trying to overcome some of...
OKKAM: Enabling Entity-centric Information Integration in the Semantic Web (2008)
Like to the way the WWW provided a global space for the seamless integration of small hypertexts into a global, open, decentralized and scalable publication space, the Semantic Web has the vision to...

Like to the way the WWW provided a global space for the seamless integration of small hypertexts into a global, open, decentralized and scalable publication space, the Semantic Web has the vision to...
Foaf-O-Matic - Solving the Identity Problem in the FOAF Network (2007)
Stefano Bortoli, Heiko Stoermer, Paolo Bouquet, Holger Wache
Abstract. An issue that is equally arising both from social networks and the Semantic Web is the fact that, without the consistent use of the same identifier for an object across systems, it is...
Paolo Bouquet, Heiko Stoermer, Xin Liu
Abstract. In Protégé, any newly created RDF/OWL knowledge base refers to local instances through a local URI, which is obtained through the concatenation of the ontology URI, the hash sign # and a...
Okkam: Towards a solution to the “identity crisis” on the semantic web (2006)
Paolo Bouquet, Heiko Stoermer, Daniel Giacomuzzi
Abstract — One of the pillars of the Semantic Web enterprise is the idea that if people use standard names for resources (URIs), then the integration of information from different distributed...
Introducing Context into RDF Knowledge Bases (2005)
Paolo Bouquet, Luciano Serafini, Heiko Stoermer
Large-scale knowledge representation (KR) with RDF unveils shortcomings which become obvious when facts have to be further qualified with contextual aspects to represent anything else but simplistic...
