Therefore suitable methods that properly exploit the different dimensions of social tagging systems data are needed. In this paper, we tackle this topic from different angles: We describe data mining methods for ubiquitous and social data, specifically focusing on physical and social activities, and provide exemplary analysis results. The present work shows, how basic approaches from the field of social network analysis and information retrieval can be applied for discovering relations among names, thus extending Onomastics by data mining techniques. Abstract In social tagging systems, like Mendeley, CiteULike, and BibSonomy, users can post, tag, visit, or export scholarly publications.

Starting from a review of linguistic definitions of word abstractness, we first use several large-scale ontologies and taxonomies as grounded measures of word generality, including Yago, Wordnet, DMOZ and Wikitaxonomy. However, little progress has been made on other issues, such as understanding the different levels of tag generality (or tag abstractness), which is essential for, among others, identifying hierarchical relationships between concepts.

In such a system, it is necessary to obtain provide brief semantic descriptions of peers, so that routing algorithms or matchmaking processes can make decisions about which communities peers should belong to, or to which peers a given query should be forwarded. We run experiments on a large-scale real-world snapshot of a social bookmarking system. It is based on a differential adaptation of the PageRank algorithm to the triadic hypergraph structure of a folksonomy.

VetImaging provides equipment, training, and support for imaging-related projects to researchers of the University of Veterinary Medicine Vienna and to external users. Core Facility for Imaging / Microscopy at VetMed University of Vienna Furthermore the facility offers workstations to the users, which allow an onsite evaluation and processing of their data with the suitable software.

This exposes important features of theinvestigated similarity measures and indicates which ones are better suited in the context of a given semantic application.}, This exposes important features of theinvestigated similarity measures and indicates which ones are better suited in the context of a given semantic application.

Assessing the degree of semantic relatedness between words is an important task with a variety of semantic applications, such as ontology learning for the Semantic Web, semantic search or query expansion. abstract = In this paper we describe our post-evaluation results for SemEval-2018 Task 7 on classification of semantic relations in scientific literature for clean (subtask 1.1) and noisy data (subtask 1.2). In this paper we describe our post-evaluation results for SemEval-2018 Task 7 on classification of semantic relations in scientific literature for clean (subtask 1.1) and noisy data (subtask 1.2).

Semantic relatedness between words has been extracted from a variety of sources. Furthermore, we provide strong evidence that the semantic nature of the underlying folksonomy is an essential factor for explaining navigation., Furthermore, we provide strong evidence that the semantic nature of the underlying folksonomy is an essential factor for explaining navigation. We discuss dynamic browsing behavior of the general user population and show that different navigational subgroups exhibit different navigational traits. Understanding their behavior and differences in behavior of different user groups is an important step towards assessing the effectiveness of a navigational concept and of improving it to better suit the users’ needs.

In order to deal with the two problems, we integrate background knowledge into the process of clustering text documents. Also, it is mostly left to the user to find out why a particular partitioning has been achieved, because it is only specified extensionally. The method is suited especially for creating/merging the top part(s) of the ontologies, where high accuracy is required, and for supporting the merging of two (or more) ontologies on that level.

Subjective versus Objective Captured Social Networks: Comparing Standard Self-Report Questionnaire Data with Observational RFID Technology Data. The application of ubiquitous and social computational systems shows a rapidly increasing trend in our everyday environments: Enhancing social interactions and communication in both online and real-world settings is an important issue in a broad range of application contexts. Exploiting social links is an important issue for enhancing ubiquitous knowledge engineering because they are a substitute for a wide range of properties depending on which relation spans the link: in case of human face-to-face contacts, similar locations or potential knowledge transfer for the people in contact can be derived.

Specifically, we consider the prediction of new links, and extend it to the analysis of recurring links. Recommender Systems are well known applications for increasing the level of relevant content over the “noise” that continuously grows as more and more content becomes available online. This is a grassroots approach to organize a site and help users to find the resources they are interested in. Furthermore, we give an overview on the Ubicon platform which provides a framework for the creation and hosting of ubiquitous and social applications for diverse tasks and projects.

We structure this presentation along the different interaction phases of a user with our system, coupling the relevant research questions of each phase with the corresponding implementation issues. Often there is no evaluation data at hand in order to validate the discovered groups. While there are a variety of methods for community mining and detection, the effective evaluation and validation of the mined communities is usually non-trivial.

Moreover, the 2009 challenge included an online task where the recommender systems were integrated into BibSonomy and provided recommendations in real time. Researchers were invited to test their methods in a competition on datasets from the social bookmark and publication sharing system BibSonomy. In particular, the task of finding relevant names for a given search query is considered as a ranking task and the performance of different measures of relatedness among given names are evaluated with respect to nameling’s actual usage data. By integrating the specifically defined personas into existing methods in the field of software engineering the feasibility of the presented approach is demonstrated.

Experiments using data from the social bookmarking system BibSonomy show that both conditions must not exclude each other. In this paper we address these questions by presenting a data privacy aware feature engineering approach. They thereby experience a conflict of interests: on the one hand, they need to identify spammers based on the information they collect about users, on the other hand, they need to respect privacy concerns and process as few personal data as possible. One major application is the detection of spam in social bookmarking systems: in order to prevent a decrease of content quality, providers need to distinguish spammers and exclude them from the system.
