In this shared task paper for SemEval-2014 Task 8, we show that most semantic structures can be approximated by trees through a series of almost bijective graph transformations. We transform input graphs, apply off-th...

Software repository data, for example in issue tracking systems, include natural language text and technical information, which includes anything from log files via code snippets to stack traces. However, data mining is often only interested in one of the two types e.g. in natural language text when looking at text mining. Regardless of which type is being investigated, any techniques used have to deal with noise caused by fragments of the other type i.e. methods interested in natural language have to deal with technical fragments and vice versa. This paper proposes an approach to classify unstructured data, e.g. development documents, into natural language text and technical information using a mixture of text heuristics and agglomerative hierarchical clustering. The approach was evaluated using 225 manually annotated text passages from developer emails and issue tracker data. Using white space tokenization as a basis, the overall precision of the approach is 0.84 and the recall is 0.85.
A compact diplexer fabricated on substrate-integrated waveguide (SIW) technology is presented. The diplexer is a sixth order coupled-resonator network with no additional elements such as power dividers, composed exclu...

The main objective of Emergency Medical Assistance services is to attend patients with sudden diseases at any possible location within an area of influence. Especially for severe emergency patients, the potential of such systems to reduce mortality is directly related to the response time, e.g., the time a patient has to wait for an ambulance. An efficient coordination of the ambulance fleet is crucial for reducing the response times of a service. And this requires complete, real-time information about the current state of the ambulance fleet. Such information is usually transmitted by the ambulance crew members. However, due to the often stressful work of those professionals, the information is frequently not sent in a timely manner. In this paper we present an approach that addresses this problem. We use a Complex Event Processing architecture to automatically identify and transmit incidents and changes in the operational states of ambulances. As a result, the availability of information in the control centre and, thus, the effectiveness of the service is improved. The system is inspired by the operational model of SUMMA112, the Emergency Medical Coordination Centre of the Autonomous Region of Madrid in Spain. Copyright 2014 ACM.
In this paper we utilize Bayesian modeling and inference to learn a softmax classification model which performs Supervised Classification and Active Learning. For p p-priors are used to impose sparsity on the adaptive...

The archeological acoustics is a part of the acoustics that allows to study ancient environments which were dedicated (completely or partly) to sound performing. The combination of this acoustic area in conjunction with room acoustics can study the acoustic evolution of existing buildings (in terms of the historical documentation) or, even, make the acoustic reconstruction of rooms which has been destroyed or they are in a bad state or in ruins. In this work, an acoustical reconstruction of the church of the Hieronymites' monastery of the Murta from the XIV century, in Alzira, Spain has been developed. This building was abandoned in the XIX century and now is in ruins. The work develops a geometrical model, together with a proposal of materials which were common in the churches of the same area, an acoustical study and finally the auralization of an organ piece (as this monastery has its own musical chappele).
In the context of Web 2.0, the users become massive producers of diverse data that can be stored in a large variety of systems. The fact that the users' data spaces are distributed in many different systems makes ...
