Dimensions of Argumentation in Social Mediaalso justify their views, giving arguments. Understanding arguments in social media would yield richer knowledge about the views of individuals and collectives. Extracting arguments from social media is difficult. Messages appear to lack indicators for argument, document structure, or inter-document

Extracting Multilingual Natural-Language Patterns for RDF Predicatesormation available on the document-oriented Web. In this paper, we present BOA, a bootstrapping strategy for extracting RDF from text. The idea behind BOA is to extract natural-language patterns that represent predicates found on the Data Web from unstructured data by using background knowledge from

Improving the Performance of a Named Entity Recognition System with Knowledge Acquisitionased on formal documents, but informal web documents usually contain noise, and incorrect and incomplete expressions. The performance of current NER systems drops dramatically as informality increases in web documents and a different kind of NER is needed. Here we propose a Ripple-Down-Rules-based N

Knowledge Extraction Based on Discourse Representation Theory and Linguistic Framesstic frame semantics, and ontology design patterns. We show that DRT-based frame detection is feasible by conducting a comparative evaluation of our approach and existing tools. Furthermore, we define a mapping between DRT and RDF/OWL for the production of quality linked data and ontologies, and pre

Ranking RDF with Provenance via Preference Aggregationnformation such as origin of data, certainty, and temporal information on . statements can be used to rank search results according to one of those dimensions. In this paper, we consider the problem of aggregating provenance information from different dimensions in order to obtain a joint ranking ov

An Interactive Guidance Process Supporting Consistent Updates of RDFS Graphsready known properties of the new object. We propose UTILIS, an interactive process to help users add new objects. While creating a new object, relaxation rules are applied to its current description to find similar objects, whose properties serve as suggestions to expand the description. A user stu

Effective Retrieval Model for Entity with Multi-valued Attributes: BM25MF and Beyondforms such as documents embedding metadata (RDF, RDFa, Microdata, Microformats). International benchmarking campaigns, e.g., the Text REtrieval Conference or the Semantic Search Challenge, propose entity-oriented search tracks. This reflects the need for an effective search and discovery of entities
