This paper aims to contribute to a theory of integration within the field of information systems (IS) project management. Integration is a key IS project management issue when new systems are developed and implemented into an increasingly integrated information infrastructure in corporate and governmental organizations. Expanding the perspective of traditional project management research, we dr...

The Arabic-Urdu-Farsi family of languages is used by over 300 million people. Unlike letters of the Roman alphabet, each Arabic character can assume different shapes which leads to a more compact representation of linguistic information, but which also causes increased difficulties in printing. In previous work IHyder, 1971], a grammatical model was developed which determines the appropriate sh...

Due to the large size of typical Enterprise Architecture models, it is often difficult for humans to fully grasp their contents. Moreover, because of their inherent complexity, the task of generating additional value from these models is very challenging without suitable analysis methods. Impact analysis, which determines the effects of changes or failures on other architectural elements, can t...

That parthood is a transitive relation is among the most basic principles of classical mereology. Alas, it is also very controversial. In a recent paper, Ingvar Johansson has put forward a novel diagnosis of the problem, along with a corresponding solution. The diagnosis is on the right track, I argue, but the solution is misleading. And once the pieces are properly put together, we end up with...

Typically native speakers of Arabic mix dialectal Arabic and Modern Standard Arabic in the same utterance. This phenomenon is known as linguistic code switching (LCS). It is a very challenging task to identify these LCS points in written text where we don’t have an accompanying speech signal. In this paper, we address automatic identification of LCS points in Arabic social media text by identif...

In a paper of W. B. Smith [1], some normal form theorems have been presented about context-sensitive grammars. Professor A. Salomaa has noticed that the proof of Lemma 2 in this paper was incorrect and he has given an example in which the proof does not work. 1 It was guessed that there was no simple way to repair Smith's proof, while M. Penttonen has found a rather complicated proof of a somew...

We present a process-calculus model for expressing and analyzing service-based systems. Our approach addresses central features of the service-oriented computational model such as distribution, process delegation, communication and context sensitiveness, and loose coupling. Distinguishing aspects of our model are the notion of conversation context, the adoption of a context sensitive, message-p...

We describe a pattern acquisition algorithm that learns, in an unsupervised fashion, a streamlined representation of linguistic structures from a plain natural-language corpus. This paper addresses the issues of learning structured knowledge from a large-scale natural language data set, and of generalization to unseen text. The implemented algorithm represents sentences as paths on a graph whos...

This paper focuses on recognizing image concepts by introducing the ISTOP model. The model parses the images from scene to object's parts by using a context sensitive grammar. Since there is a gap between the scene and object levels, this grammar proposes the “Visual Term” level to bridge the gap. Visual term is a higher concept level than the object level representing a few co-occurring object...

Secure group communication in mobile ad hoc networks is often dynamic and impromptu, and thus requires efficient and automated secure group management and seamless combination of secure groups with distributed applications running upon them. Existing approaches to secure group communication cannot satisfy these requirements. In this paper, an automated secure group management approach is presen...
