In other words, Information Extraction involves extracting the interesting information from a mass of text, and representing it in a structured format. Its basic objectives are to increase the speed and improve the quality of information processing, and ultimately release manpower from the burden of intensive and inefficient text reading.
This paper discusses the use of the basic theories of mass communication in the compilation of a journal of science and technology from the perspectives of the communication process, the assurance of the quality and the communication effects of the journal of science and technology.
By questionnaire,the authors study the status quo and motivation of the students who participate in the PE activities in Beijing PE University,and investigate the actual statue quo of the related seeing and listening to the mass media information,and then analyze it theoretically.
But there are many obstacles on the way of its development: the low level of production, the localization of TV broadcasting, the contradiction between financial TV program's given audience and TV's attribute of mass media, the single profitable mode and severe homogeneity among themselves.
The present status and development of distillation technology in China are reviewed from the point of view of distillation equipment,distillation process simulation and mass transfer dynamics,etc. Some key problems for development in this traditional discipline are discussed.
The mass fragmentation pattern of thiones is also discussed.
Two compounds were designed, synthesized, and characterized by 1H-nuclear magnetic resonance (1H-NMR), ultraviolet (UV)-visible, and matrix-assisted laser desorption/ionization (MALDI) mass spectra.
For two important special cases of mass action incidence and standard incidence, global stability of the endemic equilibrium is proved provided the threshold is larger than unity.
In this paper, a method has been established and validated for screening and identification of individual as well as total BFA by high-performance liquid chromatography and liquid chromatography/electrospray mass spectrometry in fungal raw materials.
Their structures were identified by nuclear magnetic resonance and mass spectrum.
