A Scalable Approach for Efficiently Generating Structured Dataset Topic Profiles [chapter]

Besnik Fetahu, Stefan Dietze, Bernardo Pereira Nunes, Marco Antonio Casanova, Davide Taibi, Wolfgang Nejdl
2014 Lecture Notes in Computer Science  
To address this issue, we propose an approach for creating linked dataset profiles. A profile consists of structured dataset metadata describing topics and their relevance.  ...  To enable a good trade-off between scalability and accuracy of generated profiles, appropriate parameters are determined experimentally.  ...  Our main contributions consist of (i) a scalable method for efficiently generating structured dataset profiles, combining and configuring suitable methods for NER, topic extraction and ranking as part  ...

Predicting Friendship Links in Social Networks Using a Topic Modeling Approach [chapter]

Rohit Parimi, Doina Caragea
2011 Lecture Notes in Computer Science  
As an alternative, we propose a topic modeling approach to the problem of predicting new friendships based on interests and existing friendships.  ...  We construct features for the link prediction problem based on the resulting topic distributions.  ...  A topic model, in general, is a generative model, i.e. it specifies a probabilistic way in which documents can be generated.  ...

Personalized Concept-Based Search and Exploration on the Web of Data Using Results Categorization [chapter]

Melike Sah, Vincent Wade
2013 Lecture Notes in Computer Science  
When the user selects a concept lens for exploration, results are immediately personalized.  ...  Our personalization approach is non-intrusive, privacy preserving and scalable since it does not require login and implemented at the client-side.  ...  Generally user profiles are utilized for results re-ranking. In contrast to the general approach, our personalized search approach is driven by results categorization.  ...

Monitoring Network Evolution using MDL

Jure Ferlez, Christos Faloutsos, Jure Leskovec, Dunja Mladenic, Marko Grobelnik
2008 2008 IEEE 24th International Conference on Data Engineering  
We illustrate our algorithm on synthetic and large real datasets, and we show that the results of the TimeFall agree with human intuition.  ...  Given publication titles and authors, what can we say about the evolution of scientific topics and communities over time? Which communities shrunk, which emerged, and which split, over time?  ...  In Figure 1 each box represents a community of words -a user profile topic. Each topic is thus described by a set of keywords that are characteristic for the corresponding topic.  ...

Implementing a Volunteer Notification System into a Scalable, Analytical Realtime Data Processing Environment [chapter]

Jesko Elsner, Tomas Sivicki, Philipp Meisen, Tobias Meisen, Sabina Jeschke
2016 Automation, Communication and Cybernetics in Science and Engineering 2015/2016  
This paper will focus on a basic concept for implementing a VNS approach into a scalable, fault-tolerant environment that uses state-of-the-art analytical tools to process information streams in real-time  ...  With respect to volunteer notification systems (VNS), the resulting vast amounts of data can be utilized for profiling and predicting the whereabouts of people that, combined with machine learning algorithms  ...  As clients generally subscribe to specific topics in order to achieve push-like notifications, horizontal scaling will result in brokers having different information and topic structures.  ...

Roomba

Ahmad Assaf, Aline Senart, Raphaël Troncy
2015 Proceedings of the 24th International Conference on World Wide Web - WWW '15 Companion  
In this paper, we propose Roomba, a scalable automatic approach for extracting, validating, correcting and generating descriptive linked dataset profiles.  ...  While Roomba is generic, we target CKAN-based data portals and we validate our approach against a set of open data portals including the Linked Open Data (LOD) cloud as viewed on the DataHub.  ...  In this paper, we propose Roomba, a scalable automatic approach for extracting, validating, correcting and generating descriptive linked dataset profiles.  ...

DeGPar: Large Scale Topic Detection Using Node-Cut Partitioning on Dense Weighted Graphs

Kambiz Ghoorchian, Sarunas Girdzijauskas, Fatemeh Rahimian
2017 2017 IEEE 37th International Conference on Distributed Computing Systems (ICDCS)  
In this paper we address the scalability problem by introducing an efficient and scalable graph based algorithm for TD on short texts, leveraging dimensionality reduction and clustering techniques.  ...  The results on two widely used benchmark datasets show that our algorithm not only maintains a similar or better accuracy, but also performs by an order of magnitude faster than the state-of-the-art approaches  ...  For example, it does not allow for overlapping topic structures, since the model emphasizes on an orthogonal basis for topic representation.  ...

Using DMoz for constructing ontology from data stream

M. Grobelnik, J. Brank, D. Mladenic, B. Novak, B. Fortuna
2006 28th International Conference on Information Technology Interfaces, 2006.  
In general, concepts and relations can be formed into an ontological structure either by clustering or by classification into an existing topic hierarchy.  ...  We propose the latter using DMoz as an existing topic hierarchy. The approach is efficient and can scale to large data sets.  ...  The approach proposed has a great emphasis on efficiency, scalability, and being able to process large quantities of data (hundreds of thousands of documents).  ...
