Revising Faceted Taxonomies and CTCA Expressions
A faceted taxonomy is a set of taxonomies each describing the application domain from a different (preferably orthogonal) point of view. CTCA is an algebra that allows specifying the set of meaningful compound terms (meaningful conjunctions of terms) over a faceted taxonomy in a flexible and efficient manner. However, taxonomy updates may turn a CTCA expression e ill-formed and may turn the com...
متن کاملUpdates and Revision in Faceted Taxonomies and CTCA Expressions 1
A faceted taxonomy is a forest of taxonomies each describing the application domain from a different (preferably orthogonal) point of view. CTCA is an algebra that allows specifying the set of meaningful compound terms (meaningful conjunctions of terms) over a faceted taxonomy in a flexible and efficient manner. However, taxonomy updates may turn a CTCA expression e not wellformed and may turn ...
متن کاملMulti-faceted Learning for Web Taxonomies
A standard problem for internet commerce is the task of building a product taxonomy from web pages, without access to corporate databases. However, a nasty aspect of the real world is that most web-pages have multiple facets. A web page might contain information about both cameras and computers, as well as having both specification and sale data. We are interested in methods for supervised and ...
متن کاملExtended Faceted Taxonomies for Web Catalogs
Indexing and retrieval in Web catalogs can benefit from using faceted taxonomies. A faceted taxonomy consists of a set of facets, where each facet consists of a predefined set of terms structured by a subsumption relation. We propose two extensions of faceted taxonomies, which allow inferring conjunctions of terms that are valid in the underlying domain. We give a model-theoretic interpretation...
متن کاملRapid Induction of Multiple Taxonomies for Enhanced Faceted Text Browsing
In this paper we present and compare two methodologies for rapidly inducing multiple subject-specific taxonomies from crawled data. The first method involves a sentence-level words co-occurrence frequency method for building the taxonomy, while the second involves the bootstrapping of a Word2Vec based algorithm with a directed crawler. We exploit the multilingual open-content directory of the W...
