Practical Usage of Regular Expressions

Practical Usage of Regular Expressions

Although this book concentrates on a translation tool environment, the described basic language elements and examples apply to Microsoft(R) .NET(R)-based environments, and indeed, most regex engines.

The aim of Practical Usage of Regular Expressions is to show that there are many practical uses of even simple regexes for tasks such as quality assurance (ensuring consistency), automating conversions, etc., in particular in conjunction with a translation tool, such as memoQ(R) or Trados Studio(R). Although this book concentrates on a translation tool environment, the described basic language elements and examples apply to Microsoft(R) .NET(R)-based environments, and indeed, most regex engines. Even complex constructs are explained clearly with schematic diagrams and appropriate examples. The clear structure, many illustrative examples and syntax summary make the book ideal as reference. The extensive worked example gives beginners a painless introduction to regexes, and explains all concepts needed except for the most advanced applications. The readers exercises (with solutions) also make the book ideal as tutorial. Although concise, the book provides entry- and intermediate-level regex users with detailed reference material, not just for translators, but also for general applications.

PAAMS, the International Conference on Practical Applications of Agents and Multi-Agent Systems is an international yearly forum to present, to discuss, and to disseminate the latest developments and the most important outcomes related to real-world applications. It provides a unique opportunity to bring multi-disciplinary experts, academics and practitioners together to exchange their ex-perience in the development of Agents and Multi-Agent Systems. This volume presents the papers that have been accepted for the 2010 edition in the Special Sessions and Workshops. PAAMS'10 Special Sessions and Workshops are a very useful tool in order to complement the regular program with new or emerging topics of particular interest to the participating community. Special Sessions and Workshops that emphasize on multi-disciplinary and transversal aspects, as well as cutting-edge topics were especially encouraged and welcomed.

The growth in the Bioinformatics and Computational Biology fields over the last few years has been remarkable and the trend is to increase its pace. In fact, the need for computational techniques that can efficiently handle the huge amounts of data produced by the new experimental techniques in Biology is still increasing driven by new advances in Next Generation Sequencing, several types of the so called omics data and image acquisition, just to name a few. The analysis of the datasets that produces and its integration call for new algorithms and approaches from fields such as Databases, Statistics, Data Mining, Machine Learning, Optimization, Computer Science and Artificial Intelligence. Within this scenario of increasing data availability, Systems Biology has also been emerging as an alternative to the reductionist view that dominated biological research in the last decades. Indeed, Biology is more and more a science of information requiring tools from the computational sciences. In the last few years, we have seen the surge of a new generation of interdisciplinary scientists that have a strong background in the biological and computational sciences. In this context, the interaction of researchers from different scientific fields is, more than ever, of foremost importance boosting the research efforts in the field and contributing to the education of a new generation of Bioinformatics scientists. PACBB‘13 hopes to contribute to this effort promoting this fruitful interaction. PACBB'13 technical program included 19 papers from a submission pool of 32 papers spanning many different sub-fields in Bioinformatics and Computational Biology. Therefore, the conference will certainly have promoted the interaction of scientists from diverse research groups and with a distinct background (computer scientists, mathematicians, biologists). The scientific content will certainly be challenging and will promote the improvement of the work that is being developed by each of the participants.
