Progress in the Researches on Domain Informatics

With the application of computer technology and network technology, domain informatics have generated. Almost every combination of a basic subject and informatics can generate a new field of domain informatics by cross-study. However, the development of each discipline is in a different situation and a special degree. In this paper, the authors introduce chemical informatics, bioinformatics, medical informatics, and linguistics: their definitions, researches, and


Definition of Chemical informatics
Chemical Informatics as a discipline to say the name is very new, but we will soon be able From this perspective, we intend to give a broader meaning of the definition of chemical informatics: Chemical informatics is an application of chemical methods to solve the problem of discipline 1 .

Research fields of chemical informatics
Because of the rapid development of

Research trends of Bioinformatics
The human genome project marks the results, large-scale use of highly complex mathematical and statistical models of smart, the whole system and the level of substantial biological phenomenon some new theories and doctrines.For these doctrines and theories will be to verify the biological experiments to a new height so that the biological research into systems biology of the new era.Therefore, we have every reason to believe that biological information in the 21st century will continue to be rapid development, including nanotechnology and the combination of biological medicine to have a profound revolutionary impact 4,5 .

Medical informatics 4.1 Definition of Medical informatics
Broadly speaking, the entire information in the field of health care can be called medical informatics, here the definition of Medical informatics is: The medical informatics is a new cross-edge disciplines which handling of medical information on the main subjects, the movement of medical information and its application method as the main research contents, computer as the main research tool and expansion of the information function of health care workers (especially the intellectual function) as the main research objectives.

Research fields of Medical informatics
Generally speaking, the medical information of the main areas of research includes the following four aspects.medical Information.The third and the fourth are on the medical information applications.
Understanding is the basis, the application is the goal.

Research trends of Medical informatics
Based on the details of research, we have  theory of value being represented as up, and now to rectify the "pragmatics" of misunderstanding, also its true colors.
With the development of various basic disciplines, and its rapid growth in the amount of information to information organization, management and treatment, such as job faces enormous challenges, the urgent need to improve the speed and deal with information management.The rapid development of computer technology and network technology, timely for the basic disciplines of management provides the necessary tools and technical means.And with computer technology in the chemical professional in the field of data analysis, mathematical modeling, information inquiries and deal with the work of interaction play an increasing role, attracting a lot of experts in various disciplines and the concerns of information scientists and research, and gradually formed not only an information Different from the traditional sense of the scope of study, but also on different subject areas of the traditional sense there is the very edge of the development prospects of cross-disciplinary -Domain informatics.Domain informatics is a broad concept, the paper highlights on the Zhan Yin CC: Creative Commons License, 2008.
chemical informatics, bioinformatics, medical informatics, linguistics and other fields to introduction.
to understand that it exists in around us already have a period of time.Different people often give a different definition of chemical informatics.Therefore, we have listed a few of the earliest definition: "Application of information technology and information-processing method has become the drug discovery process in a very important part of Chemical Informatics is actually a mixture of sources of information.It can be converted to compound data structure, by the structural information into knowledge, which makes our lead compounds in drug identification and organization of the decision-making process has become more effective.""Chemical Informatics -an old issue of the new term.""Chemical Informatics is a broad sense of the term; it will include the design of chemical information, creation, organization, processing, retrieval, analysis, dissemination and use."In the article, we would like to study the establishment of chemical information in the application of methods to solve the problem of the long-term development on the history, as dedicated to those who decades ago began to develop this cross-disciplinary scientists their gift.

Bioinformatics as emerging disciplines, its broad definition refers to any use of computer networks and databases and large-scale biological data collection, management and organization of the relevant research fields, and the more narrow definition refers to computer the means and methods of biological genetic information and data management and analysis.Accurately said, referring to the computational biology to computer systems and computer algorithms used in the model of biological phenomena.Bioinformatics to computer technology to study means and tools, using mathematics, statistical models, simulation of biological sciences approach to solve the problem, thereby becoming biology, statistics, mathematics, computer science or engineering, and other disciplines of The cross-cutting areas.Research fields of Bioinformatics ① the establishment and biological database search.Biological database storage of biological information on the raw data, It is the basic of existence and development.② DNA and protein sequence analysis.The existing sequence databases to identify and sequence the user the same or similar sequence, and this sequence can provide features and functions related to important information, the problem is that DNA and protein sequence similarity analysis.③ Forecast gene structure.Forecast for a section of DNA sequence or a species of the genome sequence in which specific regional representative for the function of genes encoding proteins Bioinformatics is the study of another classic problem.④ Forecast protein Zhengzhou University Press, 10. structure and function.So far despite the known protein sequence over millions, but the structure of the protein known number is still only known protein sequence of less than 2% of the total.⑤ Analysis genomic data.⑥ Comparative genomic and phylogenies genetic analysis.⑦ Functional genomics and proteomics data analysis ⑧ Signal transduction, metabolism and gene regulation means the Construction and description 3 .

Firstly, study the
concept property, nature, characterization and measurement of medical information; these are the theoretical basis of the study, including the sense of philosophy.Secondly, the study of medical information systems concept, composition, functions, principles, methods and means.Study information production, extraction, detection, the use of medical information to carry out the principles and methods of control.Under the guidance of control theory, develop a variety of information, intelligence of the diagnostic equipment.Lastly, Study the best implementation of medical information systems principles and methods of organization.Under the guidance of system theory, use of systems engineering technical, Hardware engineering, software engineering and knowledge of the method, developed the most effective medical information systems.The first and the second are the understanding of law of exercise about the tripleC i(i): pp-pp, year 5 CC: Creative Commons License, 2008.
knowledge of medical information is divided into two parts: The first part is the medical information processing tools and methods, another part of the medical fields of computer applications.At the same time we believe that medical informatics has four branches: computer tools and technology, engineering equipment and technology, medical information systems, and medical services management systems.As shown in Figure 1.
