part of the Web 2.0. In such systems

users describe bookmarks by keywords

called tags. The structure behind these social

systems, called folksonomies, can be viewed

as a tripartite hypergraph of user, tag and resource

nodes. This underlying network shows

specific structural properties that explain its

growth and the possibility of serendipitous

exploration.

Today’s search engines represent the gateway

to retrieve information from the World Wide

Web. Short queries typically consisting of

two to three words describe a user’s information

need. In response to the displayed

results of the search engine, users click on

the links of the result page as they expect

the answer to be of relevance.

This clickdata can be represented as a folksonomy

in which queries are descriptions of

clicked URLs. The resulting network structure,

which we will term logsonomy is very

similar to the one of folksonomies. In order

to find out about its properties, we analyze

the topological characteristics of the tripartite

hypergraph of queries, users and bookmarks

on a large snapshot of del.icio.us and

on query logs of two large search engines.

All of the three datasets show small world

properties. The tagging behavior of users,

which is explained by preferential attachment

of the tags in social bookmark systems, is

reflected in the distribution of single query

words in search engines. We can conclude

that the clicking behaviour of search engine

users based on the displayed search results

and the tagging behaviour of social bookmarking

users is driven by similar dynamics. ER - TY - CONF AU - Ducrou, J. AU - Vormbrock, B. AU - Eklund, P. W.

accessing information within a semantically structured information

portal, while offering the possibility to integrate own

information. It discusses research performed within the project

`Semantic Methods and Tools for Information Portals (SemIPort)'.

In particular, it focuses on (1) the development of scalable

storing, processing and querying methods for semantic data, (2)

visualization and browsing of complex data inventories, (3)

personalization and agent-based interaction, and (4) the

enhancement of web mining approaches for use within a

semantics-based portal. ER - TY - JOUR AU - Cole, Richard J. AU - Eklund, Peter W.

conceptual clustering by formal concept analysis. The program

allows users to navigate email using a visual lattice metaphor

rather than a tree. It implements a virtual file structure over

email where files and entire directories can appear in multiple

positions. The content and shape of the lattice formed by the

conceptual ontology can assist in email discovery. The system

described provides more flexibility in retrieving stored emails

than what is normally available in email clients. The paper

discusses how conceptual ontologies can leverage traditional

document retrieval systems and aid knowledge discovery in document

collections. ER - TY - CONF AU - Hotho, A AU - Staab, S. AU - Stumme, G. A2 - T1 - Wordnet improves text document clustering T2 - Proc.

In this paper we present GALOIS, a system that automates and applies this theory. The algorithm utilized by GALOIS to build a concept lattice is incremental and efficient, each update being done in time at most quadratic in the number of objects in the lattice. Also, the algorithm may incorporate background information into the lattice, and through clustering, extend the scope of the theory. The application we present is concerned with information retrieval via browsing, for which we argue that concept lattices may represent major support structures. We describe a prototype user interface for browsing through the concept lattice of a document-term relation, possibly enriched with a thesaurus of terms. An experimental evaluation of the system performed on a medium-sized bibliographic database shows good retrieval performance and a significant improvement after the introduction of background knowledge.
