Bioinformatics has been evolved into a critical inter-disciplinary field that benefits studies in both molecular biology and computer science. On the one hand, it grants the possibility to comprehend biological information and process in a more effective and efficient way by employing computational technologies to extracting knowledge from dense amounts of intermixed biological data; on the other hand, it provides a new and complex domain for researching advanced algorithms and techniques for data analysis. Nevertheless, bioinformatics also poses a great challenge to grasp for both computer science and biology majors due to its interdisciplinary and advanced natures. As many bioinformatics software tools are generally involved in analysis tasks, scientists are more and more requiring that these heterogeneous bioinformatics tools be integrated in a uniform way. They are also requiring graphical user interfaces of these tools, and the ability to compose workflows without much programming effort.

Named Entity Recognition in Natural languages u...

Named Entity Recognition (NER) aims to detect and categorize named entities in a document into certain predefined named entities classes such as Name of Person, Location, Organization, River, Location, Expressions of times, Quantities, Monetary value, Percentages, etc. In the nomenclature of computational linguistics tasks, Named Entity Recognition lies in the domain of ´´information extraction´´, which detect definite kinds of information from documents as opposed to the more general task of ´´document management´´ which seeks to extract all of the information found in a document Named Entity Recognition in Indian Languages is a very problematical task. Since, In English and in Other European Languages, the method of Capitalization makes it easy to identify the Proper Nouns in a document, which is not so in case of Indian Languages. Moreover, Indian languages are free order, and highly inflectional and morphologically rich in nature. I have performed NER using HMM in following Natural Languages: Hindi, Bengali, Telugu, Urdu, Marathi, Punjabi, English and French. I have also dealt with problem of Unknown words in Named Entity Recognition using Transliteration.

The exposition is example and problem-oriented, where the applications are taken from mathematics, numerical calculus, statistics, physics, biology and finance. The book teaches ´´Matlab-style´´ and procedural programming as well as object-oriented programming. High school mathematics is a required background and it is advantageous to study classical and numerical one-variable calculus in parallel with reading this book. Besides learning how to program computers, the reader will also learn how to solve mathematical problems, arising in various branches of science and engineering, with the aid of numerical methods and programming. By blending programming, mathematics and scientific applications, the book lays a solid foundation for practicing computational science. From the reviews: Langtangen ... does an excellent job of introducing programming as a set of skills in problem solving. He guides the reader into thinking properly about producing program logic and data structures for modeling real-world problems using objects and functions and embracing the object-oriented paradigm. ... Summing Up: Highly recommended. F. H. Wild III, Choice, Vol. 47 (8), April 2010 Those of us who have learned scientific programming in Python ´on the streets´ could be a little jealous of students who have the opportunity to take a course out of Langtangen´s Primer.´´ John D. Cook, The Mathematical Association of America, September 2011 This book goes through Python in particular, and programming in general, via tasks that scientists will likely perform. It contains valuable information for students new to scientific computing and would be the perfect bridge between an introduction to programming and an advanced course on numerical methods or computational science. Alex Small, IEEE, CiSE Vol. 14 (2), March /April 2012 ´´This fourth edition is a wonderful, inclusive textbook that covers pretty much everything one needs to know to go from zero to fairly sophisticated scientific programming in Python...´´ Joan Horvath, Computing Reviews, March 2015
