Named Entity Recognition (NER) is a well-studied area in natural language processing (NLP) and the reported results in the literature are generally very high (~>%95) for most of the languages. Today, the focus area of most practical natural language applications (i.e. web mining, sentiment analysis, machine translation) is real natural language data such as Web2.0 or speech data. Nevertheless, the NER task is rarely investigated on this type of data which differs severely from formal written text. In this paper, we present 3 new Turkish data sets from different domains (on this focused area; namely from Twitter, a Speech-to-Text Interface and a Hardware Forum) annotated specifically for NER and report our first results on them. We believe, the paper draws light to the difficulty of these new domains for NER and the possible future work.

A novel digital musical interface based on sound source localization using a microphone array is presented. It allows a performer to plan and conduct the expressivity of a performance by controlling an audio processing module in real-time through the spatial movement of a sound source (i.e., voice, traditional musical instruments, and sounding mobile devices). The prototype interface consists of an adaptive parameterized Steered Response Power Phase Transform (SRP-PHAT) with a Zero-Crossing Rate (ZCR) threshold and a Kalman filter that provides a more accurate estimate and tracking of the source position if there is movement. A real-time software based on external Max object was developed to test the system in a real-world moderately reverberant and noisy environment, focusing on the performance of pseudo-periodic sounds in a multisource scenario.

In this study, the results of the ongoing work of the authors on the topic of the analysis of the acoustical environment from reverberant signals will be presented. Initially, some theoretical aspects on the relationships of the statistical quantities of the room transfer functions and the reverberant signals will be given. Then, the way that these statistical relationships can assist acoustical scene analysis methods will be discussed. The advantage of the use of twochannel (i.e. binaural) instead of single channel signals will be underlined. Finally, the implementation details of methods for the estimation of various acoustical parameters from signals will be presented. Copyright 2012 ACM.

Nowadays, numerous daily life applications related to wireless networks, sensors, low power electronics, biomedical applications etc. demand small amount of electrical power for their operation. These applications are rapidly increasing and bringing to the fore the need for small scale electrical power generation. To this end, strong efforts are being made to exploit ambient and man made energy sources such as electromagnetic radiation including sun, infrared and RF radiation, thermal sources, mechanical stress and strain, vibrations, biochemistry etc. Acoustic signals seem to be such an alternative ambient energy source. Firstly, this work gives an overview of the proposed harvesting methods and systems derived from related patent applications during the past decade. Moreover, a first estimation of the available ambient acoustic power density is presented and then is compared to the ambient power density of the aforementioned energy sources. Copyright 2012 ACM.

Correct annotation and identification of salient regions in Kidney biopsy images can provide an estimation of pathogenesis in obstructive nephropathy. This paper presents a tool for the automatic or manual segmentation of such regions along with methodology for their characterization in terms of the exhibited pathology. The proposed implementation is based on custom code written in Java and the utilization of open source tools (i.e. RapidMiner, ImageJ). The corresponding implementation details along with the initial evaluation of the proposed integrated system are also presented in the paper.
