Author profiling consists of predicting some author’s characteristics (e.g. age, gender, personality) from her writing. After addressing at PAN@CLEF mainly age and gender identification, and also personality recognition in Twitter, in this PAN@FIRE track on Personality Recognition from SOurce COde (PR-SOCO) we have addressed the problem of predicting author’s personality traits from her source ...

Remote predictions of the nitrogen nutrition index (NNI) are useful for precise nitrogen (N) management in the field. Several studies have recommended two methods for estimating the NNI, which are classified as mechanistic and semi-empirical methods in this study. However, no studies have been conducted to thoroughly analyze and compare these two methods. Using winter wheat as an example, this ...

In this paper, we carry out a performance analysis from a probabilistic perspective to introduce the EDHVW methods’ expected performances and limitations. Then, we propose a new general error diffusion based halftone visual watermarking (EDHVW) method, Content aware Double-sided Embedding Error Diffusion (CaDEED), via considering the expected watermark decoding performance with specific content...

In this paper we report the results of a Dutch speech recognition system evaluation held in 2008. The evaluation contained mate­ rial in two domains: Broadcast News (BN) and Conversational Telephone Speech (CTS) and in two main accent regions (Flem­ ish and Dutch). In total 7 sites submitted recognition results to the evaluation, totalling 58 different submissions in the various conditions. Bes...

We revisit the problem of evaluating the performances of communication systems with optical ampliiers and a wideband optical lter. We compute the exact probability of error and the optimal threshold and compare them with those predicted by Gaussian approximations for ASK, FSK or DPSK modulations, both for ideal photodetectors and for the case where shot noise is signiicant.

The Available Bit Rate (ABR) service has been developed to support 21st century data applications over Asynchronous Transfer Mode (ATM). The ABR service uses a closed-loop rate-based traac management framework where the network divides left-over bandwidth among contending sources. The ATM Forum traac management group also incorporated open-loop control capabilities to make the ABR service robus...

The absolute time required to check and repair a file system is increasing because disk capacities are growing faster than disk bandwidth and seek time remains almost unchanged. At the same time, file system repair is becoming more common, because the per–bit error rate of disks is not dropping as fast as the number of bits per disk is growing, resulting in more errors per disk. With existing f...

The choice of block interleavers in a MIMOOFDM based broadband fixed wireless access system for the HIPERMAN and IEEE 802.16a standards with spacefrequency trellis coding under typical channel conditions is examined and block interleavers that maximise the diversity performance in typical channels is found. It has prevously been shown that a given code offers varying levels of error performance...

In this paper, we consider the improvement of packet error rate on wireless multi-hop networks. One of the important and interesting techniques for wireless multihop networks is multi-path routing. By using multipath routing, multiple routes can be established from a source node to a destination node. In this paper, we propose the error correcting scheme in which the coded different packets are...
