While the problem of recognizing relatively straight and well defined roadways in digital images has been well studied in the literature, the more difficult problem of extracting trails has received no attention. However, trails and rough roads are less likely to be adequately mapped, and change more rapidly over time. Automated tools for finding trails will be useful to cartographers, recreational users and governments. In addition, the methods developed here are applicable to the more general problem of finding linear structure. Our approach combines local estimates for image pixel trail probabilities with the global constraint that such pixels must link together to form a path. For the local part, we present results using three classification techniques. To construct a global solution (a trail) from these probabilities, we propose a global cost function that includes both global probability and path length. We show that the addition of a length term significantly improves trail finding ability. However, computing the optimal trail becomes intractable as known dynamic programming methods do not apply. Thus we describe a new splitting heuristic based on Dijkstra's algorithm. We then further improve upon the results with a trail sampling scheme. We test our approach on 500 challenging images along the 2500 mile continental divide mountain bike trail, where assumptions prevalent in the road literature are violated.}, author = {Morris, S. and Barnard, K.}, booktitle = {Computer Vision and Pattern Recognition, 2008.

Using this measure, a set X is considered similar to Y iff every point in X is close to at least one point in Y. Formally, the Hausdorff distance HausDist(X, Y) can be computed as the Max-Min distance from X to Y, i.e., find the maximum of the distance from an element in X to its nearest neighbor (NN) in Y. Although this is similar to the closest pair and farthest pair problems, computing the Hausdorff distance is a more challenging problem since its Max-Min nature involves both maximization and minimization rather than just one or the other. A traditional approach to computing HausDist(X, Y) performs a linear scan over X and utilizes an index to help compute the NN in Y for each x in X. We present a pair of basic solutions that avoid scanning X by applying the concept of aggregate NN search to searching for the element in X that yields the Hausdorff distance. In addition, we propose a novel method which incrementally explores the indexes of the two sets X and Y simultaneously. As an example application of our techniques, we use the Hausdorff distance as a measure of similarity between two trajectories (represented as point sets). We also use this example application to compare the performance of our proposed method with the traditional approach and the basic solutions. Experimental results show that our proposed method outperforms all competitors by one order of magnitude in terms of the tree traversal cost and total response time.}, acmid = {2002978}, author = {Nutanong, Sarana and Jacox, Edwin H. and Samet, Hanan}, doi = {10.14778/2002974.2002978}, interhash = {431cfc6757195ff943dc064d42e3dc57}, intrahash = {065b9da64ffb2abff443d8d9ff24abb2}, issn = {2150-8097}, issue_date = {May 2011}, journal = {Proc.

Unfortunately, the detection and characterization of power laws is complicated by the large fluctuations that occur in the tail of the distribution -- the part of the distribution representing large but rare events -- and by the difficulty of identifying the range over which power-law behavior holds. Commonly used methods for analyzing power-law data, such as least-squares fitting, can produce substantially inaccurate estimates of parameters for power-law distributions, and even in cases where such methods return accurate answers they are still unsatisfactory because they give no indication of whether the data obey a power law at all. Here we present a principled statistical framework for discerning and quantifying power-law behavior in empirical data. Our approach combines maximum-likelihood fitting methods with goodness-of-fit tests based on the Kolmogorov-Smirnov statistic and likelihood ratios. We evaluate the effectiveness of the approach with tests on synthetic data and give critical comparisons to previous approaches. We also apply the proposed methods to twenty-four real-world data sets from a range of different disciplines, each of which has been conjectured to follow a power-law distribution. In some cases we find these conjectures to be consistent with the data while in others the power law is ruled out.}, author = {Clauset, Aaron and Shalizi, Cosma Rohilla and Newman, M. E.

The development of ICT infrastructures has facilitated the emergence of new paradigms for looking at society and the environment over the last few years. Participatory environmental sensing, i.e. directly involving citizens in environmental monitoring, is one example, which is hoped to encourage learning and enhance awareness of environmental issues. In this paper, an analysis of the behaviour of individuals involved in noise sensing is presented. Citizens have been involved in noise measuring activities through the WideNoise smartphone application. This application has been designed to record both objective (noise samples) and subjective (opinions, feelings) data. The application has been open to be used freely by anyone and has been widely employed worldwide. In addition, several test cases have been organised in European countries. Based on the information submitted by users, an analysis of emerging awareness and learning is performed. The data show that changes in the way the environment is perceived after repeated usage of the application do appear. Specifically, users learn how to recognise different noise levels they are exposed to. Additionally, the subjective data collected indicate an increased user involvement in time and a categorisation effect between pleasant and less pleasant environments.

The procedure of recording, including the assignment of tags, has to be as easy-to-use as possible. We therefore discuss the application of tag recommender algorithms in this particular scenario. We show, that this task is fundamentally different from the well-known tag recommendation problem in folksonomies as users do no longer tag fix resources but rather sensory data and impressions. The scenario requires efficient recommender algorithms that are able to run on the mobile device, since Internet connectivity cannot be assumed to be available.

Such activities are represented in so-called social interaction networks or evidence networks, with different degrees of explicitness. We focus on evidence networks containing relations on users, which are represented by connections between individual nodes. Explicit interaction networks are then created by specific user actions, for example, when building a friend network. On the other hand, more implicit networks capture user traces or evidences of user actions as observed in Web portals, blogs, resource sharing systems, and many other social services. These implicit networks can be applied for a broad range of analysis methods instead of using expensive gold-standard information. In this paper, we analyze different properties of a set of networks in social media. We show that there are dependencies and correlations between the networks. These allow for drawing reciprocal conclusions concerning pairs of networks, based on the assessment of structural correlations and ranking interchangeability.

The considered approach starts with building co-occurrence graphs relative to data from the Social Web, respectively for given names and city names.

The analysis is carried out using two sociological frameworks: the Studies in Expertise and Experience (SEE) approach Collins and Evans, and mechanisms of sociological and institutional trust in the general sociology of science literature. I argue that the communication process is carried out in two ways: through interactional expertise that is based on deep comprehension when the interaction is between micro-cultures that are sociologically closely connected, and through lower forms of knowledge relying on trust for the micro-cultures that are sociologically far apart. Because the SEE framework is strongly based on the transmission of tacit knowledge, an analysis of the importance of tacit knowledge in theoretical physics is carried out to support the SEE analysis, and specific types of tacit knowledge are closely examined to understand how they shape theoretical physics practice. I argue that `physical intuition', one of the guiding principles of all theoretical activity, is in fact a type of tacit knowledge -somatic tacit knowledge- that is well known within social studies of science. The end result is a description of physics that highlights the importance of sociological mechanisms that hold the discipline together, and that permit knowledge to flow from the empirical to the theoretical poles of physics practice.

Finally, we argue the need for a unified architecture and envision the requirements it must satisfy.}, author = {Ganti, R.K. and Ye, Fan and Lei, Hui}, doi = {10.1109/MCOM.2011.6069707}, interhash = {8e5a7301965e4703f5caaf45f7a823d4}, intrahash = {44321e103e910e997453ffcb9877ac73}, issn = {0163-6804}, journal = {Communications Magazine, IEEE}, number = 11, pages = {32-39}, title = {Mobile crowdsensing: current state and future challenges}, url = {http://ieeexplore.ieee.org/xpl/login.jsp?tp=&arnumber=6069707&url=http%3A%2F%2Fieeexplore.ieee.org%2Fxpls%2Fabs_all.jsp%3Farnumber%3D6069707}, volume = 49, year = 2011 } @book{mitchell2010machine, address = {New York, NY [u.a.}, author = {Mitchell, Tom M.}, interhash = {8be657b11d4324941ba419c176c0229a}, intrahash = {adfebd1b18f04021ba0edd69ccaa3d96}, isbn = {0071154671 9780071154673}, publisher = {McGraw-Hill}, refid = {846511832}, title = {Machine learning}, url = {http://www.amazon.com/Machine-Learning-Tom-M-Mitchell/dp/0070428077}, year = 2010 } @article{gyongyi2004combating, author = {Gyöngyi, Zoltán and Garcia molina, Hector and Pedersen, Jan}, interhash = {428bfe5366151d07a234864481364e60}, intrahash = {cb480eab1c421d316fb8cb83f9688af3}, pages = {576--587}, title = {Combating web spam with trustrank}, url = {http://citeseer.uark.edu:8080/citeseerx/viewdoc/summary?doi=10.1.1.122.8129}, year = 2004 } @inproceedings{Scholz:2012:PHC:2411131.2411662, abstract = {While the analysis of online social networks is a prominent research topic, offline real-world networks are still not covered extensively.

This representation consists of optimal (in a least-squares sense) estimators of trend aspects of a time series such as average, slope, curve, change of curve, etc. The shape space representation of time series allows for a definition of a novel similarity measure for time series which we call shape space distance measure. Depending on the application, time series segmentation techniques can be applied to obtain a piecewise shape space representation of the time series in subsequent segments. In this article, we investigate the properties of the polynomial shape space representation and the shape space distance measure by means of some benchmark time series and discuss possible application scenarios in the field of temporal data mining.}, author = {Fuchs, Erich and Gruber, Thiemo and Pree, Helmuth and Sick, Bernhard}, doi = {10.1016/j.neucom.2010.03.022}, interhash = {88c499ac1dc9e9708e70187967494219}, intrahash = {fdf6865c1bece3f77cc3e29365a2c6b3}, issn = {0925-2312}, journal = {Neurocomputing}, note = {Artificial Brains}, number = {1–3}, pages = {379 - 393}, title = {Temporal data mining using shape space representations of time series}, url = {http://www.sciencedirect.com/science/article/pii/S0925231210002237}, volume = 74, year = 2010 } @incollection{ABP:11, author = {Atzmueller, Martin and Beer, Stephanie and Puppe, Frank}, booktitle = {Collaboration and the Semantic Web: Social Networks, Knowledge Networks, and Knowledge Resources}, editor = {Brüggemann, Stefan and d’Amato, Claudia}, interhash = {9c0d3f10e985d8654d8a2eae39121ef2}, intrahash = {781410de8780f9033aae08162cbdf073}, pages = {149-167}, publisher = {IGI Global}, title = {{Data Mining, Validation and Collaborative Knowledge Capture}}, year = 2012 } @article{strohmaier2011evaluation, author = {Strohmaier, Markus and Helic, Denis and Benz, Dominik and Körner, Christian and Kern, Roman}, interhash = {87e110b0ade230877db6855cacabcb4d}, intrahash = {603161eb4c5b2f87f3d3a50f87015337}, journal = {Transactions on Intelligent Systems and Technology}, title = {Evaluation of Folksonomy Induction Algorithms}, url = {http://tist.acm.org/index.html}, vgwort = {43}, year = 2012 } @article{Atzmueller:12, author = {Atzmueller, Martin}, interhash = {ce21e72d189207dbee58420af81efca8}, intrahash = {a66dc503e2f90d0a484e0dbef5febcd3}, journal = {Informatik Spektrum}, number = 2, pages = {132-135}, title = {Mining Social Media}, volume = 35, year = 2012 } @inproceedings{Atzmueller:12b, address = {New York, NY, USA}, author = {Atzmueller, Martin}, booktitle = {Proc. 3rd International Workshop on Modeling Social Media (MSM 2012), Hypertext 2012}, interhash = {59cc9a3c8221ebd802aa85acaba4506f}, intrahash = {52600def4f1f0d36b86ed4fbd15e353a}, publisher = {ACM Press}, title = {{Onto Collective Intelligence in Social Media: Exemplary Applications and Perspectives}}, year = 2012 } @incollection{LA:12, address = {Heidelberg, Germany}, alteditor = {Editor}, author = {Lemmerich, Florian and Atzmueller, Martin}, booktitle = {{Modeling and Mining Ubiquitous Social Media}}, interhash = {ae9dc5bfe7f42f1e9ca59aadda4bfd9e}, intrahash = {8435f029bf0e32340e2cf44d0eeb65e7}, publisher = {Springer Verlag}, series = {LNAI}, title = {{Describing Locations using Tags and Images: Explorative Pattern Mining in Social Media}}, url = {http://www.kde.cs.uni-kassel.de/atzmueller/paper/lemmerich-explorative-pattern-mining-socia-media-lnai-2012.pdf}, volume = 7472, year = 2012 } @proceedings{CAH:12, address = {New York, NY, USA}, editor = {Chin, Alvin and Atzmueller, Martin and Helic, Denis}, interhash = {8c21f6c9eb9d4658ca2374f12a63e950}, intrahash = {338ca2515a0f6cd77996d1bbf54c7f4d}, publisher = {ACM Press}, title = {{Proceedings MSM 2012: Workshop on Modeling Social Media -- Collective Intelligence in Social Media}}, year = 2012 } @inproceedings{AL:12a, address = {Heidelberg, Germany}, author = {Atzmueller, Martin and Lemmerich, Florian}, booktitle = {Proc.

Few approaches for recommending tags to a user for a document address this new item problem, concentrating instead on artificially created post-core datasets where it is guaranteed that the user as well as the document of each test post is known to the system and already has some tags assigned to it. In order to recommend tags for new documents, approaches are required which model documents not only based on the tags assigned to them in the past (if any), but also the content. In this paper we present a novel adaptation to the widely recognised FolkRank tag recommendation algorithm by including content data. We adapt the FolkRank graph to use word nodes instead of document nodes, enabling it to recommend tags for new documents based on their textual content. Our adaptations make FolkRank applicable to post-core 1 ie. the full real-world tagging datasets and address the new item problem in tag recommendation. For comparison, we also apply and evaluate the same methodology of including content on a simpler tag recommendation algorithm. This results in a less expensive recommender which suggests a combination of user related and document content related tags.

Including content data into FolkRank shows an improvement over plain FolkRank on full tagging datasets. However, we also observe that our simpler content-aware tag recommender outperforms FolkRank with content data. Our results suggest that an optimisation of the weighting method of FolkRank is required to achieve better results.}, acmid = {2365936}, address = {New York, NY, USA}, author = {Landia, Nikolas and Anand, Sarabjot Singh and Hotho, Andreas and Jäschke, Robert and Doerfel, Stephan and Mitzlaff, Folke}, booktitle = {Proceedings of the 4th ACM RecSys workshop on Recommender systems and the social web}, doi = {10.1145/2365934.2365936}, interhash = {7400e35f8d412d15722fe3399aba14a3}, intrahash = {200a05b24a08dd33e377838ae5bdcf71}, isbn = {978-1-4503-1638-5}, location = {Dublin, Ireland}, numpages = {8}, pages = {1--8}, publisher = {ACM}, series = {RSWeb '12}, title = {Extending FolkRank with content data}, url = {http://doi.acm.org/10.1145/2365934.2365936}, year = 2012 } @book{ACHH:12, address = {Heidelberg, Germany}, editor = {Atzmueller, Martin and Chin, Alvin and Helic, Denis and Hotho, Andreas}, interhash = {ebf8e8b66c6c0723092e11e40998d61f}, intrahash = {a0e5d144b39199fa4acb6319f29e7a15}, publisher = {Springer Verlag}, series = {Lecture Notes in Computer Science}, title = {Modeling and Mining Ubiquitous Social Media}, url = {http://www.springer.com/computer/ai/book/978-3-642-33683-6}, volume = 7472, year = 2012 } @inproceedings{SNKA:12, address = {Bristol, UK}, author = {Seipel, Dietmar and Neubeck, Philipp and Köhler, Stefan and Atzmueller, Martin}, booktitle = {Proc.
