Yahoo! as an ontology

Yannis Labrou, Tim Finin
1999 Proceedings of the eighth international conference on Information and knowledge management - CIKM '99  
We suggest that one (or a collection) of names of Yahoo! (or any other WWW indexer's) categories can be used to describe the content of a document.  ...  We use Telltale as our classifier; Telltale uses n-grams to compute the similarity between documents. We experiment with various types of descriptions for the Yahoo!  ...  categories, our larger point is that Yahoo! categories can be used as a standardized way for referring to or describing the "nature" of things.  ...

Automatic Topic Identification Using Ontology Hierarchy [chapter]

Sabrina Tiun, Rosni Abdullah, Tang Enya Kong
2001 Lecture Notes in Computer Science  
The fundamental idea behind this work is to exploit an ontology hierarchical structure in order to find a topic of a text.  ...  This situation forces us to extend the ontology by enriching each of its concepts with new concepts using the external linguistics knowledge-base (WordNet).  ...  These retrieved words from WordNet will be treated as the extension of Yahoo hierarchy. The enrichment of Yahoo concept using WordNet words is not as easy as seen.  ...

Mobile web search personalization using ontological user profile

Kapil Goenka, I. Budak Arpinar, Mustafa Nural
2010 Proceedings of the 48th Annual Southeast Regional Conference on - ACM SE '10  
Our approach involves building an ontological model of user interests on the user's mobile device based on his interaction with web search results.  ...  Personalizing web search involves the process of identifying user interests during interaction with the user, and then using that information to deliver results that are more relevant to the user.  ...  of Number of Categories on Classifier precision section 4.3, i.e., using all documents under a concept as training documents.  ...

Lightweight Ontologies [chapter]

Fausto Giunchiglia, Ilya Zaihrayeu
2017 Encyclopedia of Database Systems  
All ontologies in this category are classification ontologies, for which the "intersection" relation creates an additional dimension of power of classification by allowing it to describe a specific set  ...  It is typical to characterize ontologies based on the degree of formality and expressivity of the language used to describe them.  ...

Automatic document-level semantic metadata annotation using folksonomies and domain ontologies

Hend S. Al-Khalifa, Jessica Rubart
2008 ACM SIGWEB Newsletter  
Folksonomies are ad hoc, light-weight knowledge representation artefacts to describe web resources using people's own vocabulary.  ...  This thesis presents a novel tool that uses folksonomies to automatically generate metadata with educational semantics in an attempt to provide semantic annotations to bookmarked web resources, and to  ...  using an ontological approach such as .  ...

Semantic matching in hierarchical ontologies

Sharifullah Khan, Muhammad Safyan
2014 Journal of King Saud University: Computer and Information Sciences  
Hierarchical ontologies play a key role in organizing documents in a repository. While matching the ontologies, the relationships among the concepts are considered to be a major aspect.  ...  In this paper, we discuss an approach for matching heterogeneous hierarchical ontologies that are related to the same domain through the semantic interpretation and implicit context of the concepts.  ...  ACM CCS classifies the Computer Science discipline, and MSC is used to classify Mathematics-related documents.  ...

Personal ontologies for web navigation

Jason Chaffee, Susan Gauch
2000 Proceedings of the ninth international conference on Information and knowledge management - CIKM '00  
As the number of Internet users and the number of accessible Web pages grows, it is becoming increasingly difficult for users to find documents that are relevant to their particular needs.  ...  This system is built by using the characterizations for a particular site created by the Ontology Based Informing Web Agent Navigation (OBIWAN) system and mapping from them to the user's personal ontologies  ...  The system developed by Labrou and Finin [24] uses Yahoo! [25] as an ontology. The system semantically annotates Web pages via the use of Yahoo! categories as descriptors of their content.  ...

2005 The AI Magazine  
As an example, the use of precedence to reflect business rules has not been applied elsewhere, to the best of our knowledge.  ...  We propose the use of application semantics to enhance the process of semantic reconciliation.  ...  Acknowledgements Our thanks is given to Louiqa Raschid and An-Hai Doan for useful discussions.  ...
