Extracting Comparative Commonsense from the Web [chapter]

Yanan Cao, Cungen Cao, Liangjun Zang, Shi Wang, Dongsheng Wang
2010 IFIP Advances in Information and Communication Technology  
We firstly extract potential comparative statements from related texts based on multiple lexico-syntactic patterns. Then, we assess the candidates using Web-scale statistical features.  ...  Comparative commonsense, such as "In general, a man is stronger than a woman", denotes that one entity has a property or quality greater or less in extent than that of another.  ...  Then, we assess the candidates based on multiple Web-scale statistical features.  ...

Extraction of Relevant Resources and Questions from DBpedia to Automatically Generate Quizzes on Specific Domains [chapter]

Oscar Rodríguez Rocha, Catherine Faron Zucker, Alain Giboin
2018 Lecture Notes in Computer Science  
The production of quizzes is a time-consuming task that can be automated by taking advantage of existing knowledge bases available on the Web of Linked Open Data (LOD).  ...  Such heuristic has been implemented and used for the automatic generation of quizzes in the geography and privacy domains. We report a comparative user evaluation of it.  ...  Since the knowledge bases on the Semantic Web use different ontologies and ways of structuring their data, we decided to focus our study on DBpedia since it is widely used and provides a large amount of  ...

Combining Linked Data and Statistical Information Retrieval [chapter]

Ricardo Usbeck
2014 Lecture Notes in Computer Science  
By using Semantic Web methods and Linked Data the doctoral work will present how the underlying knowledge is created and elaborated searches can be performed on top.  ...  The Semantic Web provides necessary procedures to augment the highly unstructured Web with suitable metadata in order to leverage search quality and user experience.  ...  It is a web-scale semantic relation extraction framework capable to identify known as well as novel relations on Web pages creating RDF out of them.  ...

Semi-Automatic Semantic Annotations for Web Documents

Nadzeya Kiyavitskaya, Nicola Zeni, James R. Cordy, Luisa Mich, John Mylopoulos
2005 Semantic Web Applications and Perspectives  
Considering the scale and dynamics of worldwide web, the largest knowledge base ever built, it becomes clear that we cannot afford to annotate web documents manually.  ...  Semantic annotation of the web documents is the only way to make the Semantic Web vision a reality.  ...  Also KIM has a knowledge base of approximately 80,000 entities of general importance to allow information extraction on inter-domain web content. -Methodology.  ...

Discovering Non-taxonomic Relations from the Web [chapter]

David Sánchez, Antonio Moreno
2006 Lecture Notes in Computer Science  
The discovery of non-taxonomical relationships is one of the less studied knowledge acquisition tasks, even though it is a crucial point in ontology learning.  ...  We also discuss how the obtained relationships may be automatically evaluated, using relatedness measures based on WordNet.  ...  Moreover, web search engines can provide confident measures (web-scale statistics) in an immediate way if the appropriate search queries are formulated [9] .  ...

Refined Commonsense Knowledge from Large-Scale Web Contents [article]

Tuan-Phong Nguyen, Simon Razniewski, Julien Romero, Gerhard Weikum
2022 arXiv   pre-print
This paper presents a method called ASCENT++ to automatically build a large-scale knowledge base (KB) of CSK assertions, with refined expressiveness and both better precision and recall than prior works  ...  For high coverage, our method taps into the large-scale crawl C4 with broad web contents.  ...  In contrast, ASCENT++ extracts concept-centric knowledge explicitly mentioned in a large web corpus.  ...

Automated story capture from internet weblogs

Andrew S. Gordon, Qun Cao, Reid Swanson
2007 Proceedings of the 4th international conference on Knowledge capture - K-CAP '07  
We describe the large-scale application of story extraction technology to Internet weblogs, producing a corpus of stories with over a billion words.  ...  Millions of these stories appear in Internet weblogs, offering a potentially valuable resource for future knowledge management and training applications.  ...  By extrapolation, we can estimate that there are 23.8 billion words of story text available on the web for use in knowledge management and training applications.  ...
