Special Issue on Fire Model Validation

Editorial: special issue on verification and validation

As for any software , users of knowledge-based systems (KBS) need to know that they can rely on the system to do its job properly. Assuring the reliability of knowledge-based systems has become an important issue in the development of the knowledge engineering discipline. The processes employed directly to assure the reliability of software are called verification and validation (V & V). Roughl...

Special Issue on Global Land Product Validation

I N PARALLEL with the recent bloom of sensors providing frequent medium-resolution observations (Fig. 1), global land products have been increasingly developed and released within the community. The raw data acquired by these sensors are transformed into higher level products that can be more easily exploited by the user community. In many cases, multiple products are developed from each sensor...

Special Issue on Model-Based Testing

With the ever-increasing penetration of software-intensive systems into technical, business and social areas, not only the requirements on system functionality and features, but also the requirements on system quality and reliability are increasing. With the increasing requirements, the complexity of such software-intensive systems is growing – this combined with ever shortened development time...

The main aim of this study is to develop part-of-speech tagger for Afaan Oromo language. After reviewing literatures on Afaan Oromo grammars and identifying tagset and word categories, the study adopted Hidden Markov Model (HMM) approach and has implemented unigram and bigram models of Viterbi algorithm. Unigram model is used to understand word ambiguity in the language, while bigram model is u...
