The conducts to copy using other person's source codes and submit as reports are regarded as a problem for program exercises of programming subjects in universities or colleges. An automatic detection algorithm to detect illicit copies is required in these educational organizations. In previous researches, these methods based on the detection standard of the token length have been proposed. These methods use the threshold simply using the character length. In these cases, miss detections occur in the case of the simple program such as the sequence of the print statement or the case that token sequences appear in the middle of a statement. This paper proposes the detection method using the program complexity and the complete token sequence. As the results of experiments, our method can improve the recall R adopting the complexity as the detection standard and the precision P adopting the complete token sequence for exercise programs submitted by students.

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.

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.

The management of university web sites is becoming more critical than before due to the rapid growth of the population dep.ndent on the world wide web as the most important (if not the only) information source. A university can spread its research outcomes and education achievements through its web site, and consequently gain visibility and influence from the web population. Webometrics Ranking of World Universities (WR) proposed by Centre for Scientific Information and Documentation (CINDOC-CSIC), which ranks the university web sites, has obtained much attention recently. The rankings of WR are well recognized as an important index for universities willing to promote themselves by the internet technology. In this paper, we proposed WRES as an early warning system for Webometrics Rankings. WRES gathers the WR indices from the WWW automatically in flexible periods, and provides useful information in real time for the managers of university web sites. If the WR ranking of an institution is below the expected position according to their academic performance, university authorities should reconsider their web policy, by promoting substantial increases of the volume and quality of their electronic publications. Besides, the web site manages may adopt effective approaches to promote their WR rankings according to the hints given by WRES. © (2012) Trans Tech Publications, Switzerland.

The Internet has emerged to be an effective platform for world universities to share their academic outcomes and to show their influence and contribution via constructing rich and easy-to-access web sites. At the same time, Webometrics Ranking of World Universities (WR), proposed by Centre for Scientific Information and Documentation (CSIC), ranks the world universities by the quantity of digital documents available on their web sites and the quality of the web pages measured by the incoming hyperlinks. Therefore, WR is currently recognized as an important index and opportunity for universities willing to promote themselves by the Internet technology. In this paper, we propose a novel cloud-based information providing system for Webometrics Rankings which employs web mining techniques to gather the WR indices from the Internet automatically, and provides useful information in real time for the managers of university web sites. The proposed system is dep.oyed on Microsoft Azure cloud platform in order to give up-to-data and deeper insights of the WR ranking indicators for its users. It utilizes the scalable computation and storage capability of the cloud platform to continually gather the WR index data from the Internet. The proposed system is designed with architecture suitable for cloud-based application such that the period to thoroughly update the WR ranking data is shortened from six months to be within one week. The proposed service model provides a paradigm for constructing cloud-based service of information providing applications. © 2012 IEEE.

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.

Boolean satisfiability (SAT) solvers are used heavily in electronic engineering verification tools for checking satisfiability of Boolean formulas. Most state-of-the-art SAT solvers are based on the DPLL algorithm and require the input formula to be in conjunctive normal form (CNF). We represent the vhpform of a given NNF formula in the form of two graphs called vpgraph and hpgraph. The input formula is translated into a 2-dimensional format called vertical-horizontal path form (vhpform). In this form disjuncts (operands of) are arranged orizontally and conjuncts (operands ofˆ) are arranged *** formula is satisfiable if and only if there exists a vertical path through this arrangement that does not contain two opposite literals (l and ¬l). The input formula is not required to be in CNF. This algorithm is very important both for the design of integrated circuit and the development of electronic engineering. © 2012 Springer-Verlag Berlin Heidelberg.

Web 2.0 has facilitated interactive information sharing on the WWW, allowing users the opportunity to articulate their opinions on different topics. In this framework, certain practices implement information monitoring systems so as digests, reports on keywords and thematic queries regarding opinions on government decisions to be created. Analysis of rubrics associations, primary semantic and statistical interpretation of the texts is usually carried out. It is, on the other hand, rather difficult to get punctual predicts and estimate sufficiently forum users' opinion strength. In this work we present a methodology which automatically mines and estimates the strength of users' opinions on text forums regarding government decisions. According to our methodology, quantitative features are automatically mined from forum posts and then passed to a Support Vector Machine based classifier where the users' opinion strength is estimated. The proposed methodology has been validated in real data and initial experimental results are presented. © 2012 IFIP International Federation for Information Processing.
