In this paper, the specific trait of Persian signatures is applied to signature verification. Efficient features, which can discriminate among Persian signatures, are investigated in this approach. Persian signatures, in comparison with other languages signatures, have more curvature and end in a specific style. An experiment has been designed to determine the function indicating the most robus...

Kooperative Medien sind Softwaretools und Netzdienste, die sowohl synchrone und asynchrone Kommunikation unterstützen als auch den Aufbau virtueller Gemeinschaften ermöglichen. Weblogs sind vor diesem Hintergrund als eine Form web-basierter kooperativer Medien zu verstehen. Solche Medien spielen bei der Gestaltung neuer Lehrund Lernformen für die Lehre an Hochschulen eine immer stärkere Rolle. ...

In the 1980s we witnessed the dawning of the Information Age. Today, the use of information technology has become an integral part of our lives. Education is no exception. With the introduction of Web 2.0 tools such as weblogs, students are presented a new platform for interaction and exchanging ideas. A review of the literature however reveals few empirical studies examining the relationship o...

Weblogs have become a leading form of self-publication on the web. Personal weblogs are often considered to represent a person, and the links between webogs can naturally be given a social interaction. Against this background, finding a community around a given weblog—i.e., identifying a set of weblogs that forms a natural group together with the starting point, because of content or social rea...

This paper presents an automated supervised method for Persian wordnet construction. Using a Persian corpus and a bi-lingual dictionary, the initial links between Persian words and Princeton WordNet synsets have been generated. These links will be discriminated later as correct or incorrect by employing seven features in a trained classification system. The whole method is just a classification...

In this paper, a new proposed system for Persian printed numeral characters recognition with emphasis on representation and recognition stages is introduced. For the first time, in Persian optical character recognition, geometrical central moments as character image descriptor and fuzzy min-max neural network for Persian numeral character recognition has been used. Set of different experiments ...

The Persian Universal Dependency Treebank (Persian UD) is a recent effort of treebanking Persian with Universal Dependencies (UD), an ongoing project that designs unified and cross-linguistically valid grammatical representations including part-of-speech tags, morphological features, and dependency relations. The Persian UD is the converted version of the Uppsala Persian Dependency Treebank (UP...
