Introduction Cri du chat syndrome is a rare genetic disorder due to deletion of variable length of short arm of chromosome 5(5p). It mainly presents with typical cat like cry, facial dysmorphism, poor growth with feeding problems and severe cognitive, speech, and motor delays. Case Report We present here a one year old child who did not presented with typical features but presented with recurre...

Malicious users on chat network systems would reduce the willingness of benevolent users to chat on the same network. Thus it is often desirable to classify malicious users based on their personal profile and chat contents. In this study, different algorithms including Naive Bayes, SVM, Decision Table, Multilayer Perceptron, and Logistic classification are applied on the dataset from an anonymo...

This paper investigates the use of chat by Greek students. An appropriate questionnaire was developed. Among others, the questions attempted to identify the users’ preferences regarding chat rooms and discussion subjects, their expectations for advanced chat features, as well as the relation between chat and normal life. The questionnaire was

Chat rooms and newsgroup on the internet is a valuable, and often free of charge, source of information. In this paper, a design of smart chat room bots that automatically retrieve and filter on line messages is proposed. The design is based on internet technology and Bayesian Networks. Technical details of connecting to and retrieving data from web based chat room servers are presented. A Naiv...

In recent years many online text chat systems have been developed and use. Internet Relay Chat or IRC, ICQ, AOL and MSN are some examples of the most popular tools for real-time communications via the Internet and have been used both for doing serious work [4], decision making [5] and for entertainment purpose. Messaging programs tend to imitate each other and they imitate other chat programs e...

Purpose This paper studies the characteristics of chat messages from analyzing a collection of 33,121 sample messages gathered from 1700 sessions of conversations of 72 pairs of MSN Messenger users over 4-month duration from June to September of 2005. The primary objective of chat message characterization is to understand the properties of chat messages for effective message analysis such as me...

Release of acetylcholine (ACh) in the hippocampus (HC) occurs during exploration, arousal, and learning. Although the medial septum-diagonal band of Broca (MS-DBB) is the major extrinsic source of cholinergic input to the HC, cholinergic neurons intrinsic to the HC also exist but remain poorly understood. Here, ChAT-tauGFP and ChAT-CRE/Rosa26YFP (ChAT-Rosa) mice were examined in HC. The HC of C...

We consider the task of classifying chat contributions by dialogue act in a multi-party setting. This extends the problem significantly over the 1-1 chat scenario due to the semiasynchronous and “entangled” nature of the contributions by chat participants. We experiment with a number of machine learning approaches, using different categories of features: lexical, contextual, structural, keyword...
