Information Retrieval in Folksonomies: Search and Ranking
TLDR
We present a formal model and a new search algorithm for folksonomies, called FolkRank, that exploits the structure of the folksonomy. Expand
Learning Concept Hierarchies from Text Corpora using Formal Concept Analysis
TLDR
We present a novel approach to the automatic acquisition of taxonomies or concept hierarchies from a text corpus. Expand
Tag Recommendations in Folksonomies
TLDR
We evaluate and compare two recommendation algorithms on large-scale real life datasets: an adaptation of user-based collaborative filtering and a graph-based recommender built on top of FolkRank. Expand
A Brief Survey of Text Mining
TLDR
The enormous amount of information stored in unstructured texts cannot simply be used for further processing by computers, which typically handle text as simple sequences of character strings. Expand
Tag recommendations in social bookmarking systems
TLDR
We evaluate and compare several recommendation algorithms on large-scale real life datasets: an adaptation of user-based collaborative filtering, a graph-based recommender built on top of the FolkRank algorithm and simple methods based on counting tag occurrences. Expand
BibSonomy: a social bookmark and publication sharing system
Auch erschienen in: Moor, Aldo de u.a. (Hrsg.): Proceedings of the First Conceptual Structures Tool Interoperability Workshop at the 14th International Conference on Conceptual Structures. Aalborg :Expand
WordNet improves text document clustering
TLDR
Text document clustering plays an important role in providing intuitive navigation and browsing mechanisms by organizing large amounts of information into a small number of meaningful clusters. Expand
Ontologies improve text document clustering
TLDR
We integrate core ontologies as background knowledge into the process of clustering text document clustering by integrating an explicit conceptual account of terms found in thesauri and ontologies like WordNet. Expand
FolkRank : A Ranking Algorithm for Folksonomies
TLDR
We present a formal model and a new search algorithm for folksonomies, called FolkRank, that exploits the structure of the folksonomy. Expand
Evaluating similarity measures for emergent semantics of social tagging
TLDR
Social bookmarking systems are becoming increasingly important data sources for bootstrapping and maintaining Semantic Web applications. Expand
