This paper improves the traditional text mining technology which cannot understand the text semantics. The author discusses the text mining methods based on ontology and puts forward text mining model based on domain ontology. Ontology structure is built firstly and the "concept-concept" similarity matrix is introduced, then a conception vector space model based on domain ontology is used to take the place of traditional vector space model to represent the documents in order to realize text mining. Finally, the author does a case and draws some conclusions. © ifip international Federation for Information Processing 2014.

INTERNET USAGE IN THE FRESH PRODUCE SUPPLY CHAIN IN CHINA 2nd

2nd ifip international conference on computer and computing technologies in agriculture

Although effective implementation of the Internet technologies has a great potential for improving efficiency and reducing wastage within the fresh produce supply chain. the situation of the Internet usage by SMEs (small and medium sized enterprises) in the fresh produce supply chain is still unclear in China. As the main players, SMEs haven't been given enough attention from both academics and governments. Therefore, this research attempts to address this issue by, first, investigating the current usage of the Internet and related software by Chinese SMEs in the fresh produce supply chain, and then, by identifying enablers and barriers faced by SMEs to call government's attention. As a part of an EU-Asia IT&C funded project, a survey was carried out with SMEs in this industry from five major cities in China. The results reveal that in the relatively developed areas of China, SMEs in the fresh produce supply chain are rapidly adopting the Internet and software packages, but the level of adoption varies greatly and there is a significant lack of integration among the supply chain partners. Chinese SMEs are keen to embrace emerging technologies and have acted to adopt new software and tools. Given that cost of implementation is not a barrier, their concern over legal protection and online security must be addressed for further development.

Faced with huge amounts of information to realize the accurate retrieval under the network environment, the first step is indexing words cannot appear ambiguity word. Because Chinese’s the basic unit is Chinese characters, Chinese characters form words, Word is divided into monosyllabic word and compound word, and there's no space between Chinese keywords and there are a lot of ambiguous concept. Therefore a lot of ambiguity in the indexing process will be produced. The result detected information of irrelevant or mistakenly identified. The paper focuses on a method to eliminating the crossed meanings ambiguous words in the automatic indexing. The paper puts forward a method to eliminating ambiguous words combined algorithm of exhaustive method and disambiguation rules. Experiments show that it can avoid a great lot segmenting ambiguities with better segmenting results. © ifip international Federation for Information Processing 2014.

As process technology scales down, power wall starts to hinder improvements in processor performance. Performance optimization has to proceed under a power constraint. The co-optimization requires exploration into a huge design space containing both performance and power factors, whose size is over costly for extensive traditional simulations. This paper describes a unified model covering both performance and power. The model consists of workload parameters, architectural parameters plus corresponding power parameters with a good degree of accuracy compared with physical processors and simulators. We apply the model to the problem of co-optimizing the power and performance. Concrete insights into the tradeoffs of designs for performance and power are obtained in the process of co-optimization. © ifip international Federation for Information Processing 2006.

Precision agriculture is a modern improvised online farming management concept. It is otherwise named as Internet based farming or Site specific crop management. The field parameters are observed, measured and monitored through wireless technology. It provides a Decision Support System for whole Agricultural management. The main focus of PA is optimal utilization of input resources and getting better productivity and high yield. Various machine learning approaches are used for optimizing the resource utilization among them Enhanced Learning Machine technique is used mostly and it is found that 86% accuracy achieved in regression with artificial neural network proposed by Priyadarshini A. ***. In this modernized technology, Wireless sensor nodes play a major role in collecting different types of soil parameters and uploaded at base station through gateway and Radio Frequency plays major role in communication. The data must be perfectly monitored for proper agri-decision. ELM is about Empirical Risk Minimization technique and its learning process needs only a single iteration. It avoids multiple iteration and local minimization. This technique is widely applied in various fields due to better generalization ability, robustness, control features with fast learning rate. © 2022 IEEE.

DIGITAL IMAGE ANALYSIS OF REACTIVE OXYGEN SPECIES And CA2+IN MOUSE 3T3 FIBROBLASTS 2nd

Recently, analysis of digital images with confocal microscope has become a routine technique and indispensable tool for cell biological studies and molecular investigations. Because the light emitted from the point out-of-focus is blocked by the pinhole and can not reach the detector, thus only an image of the fluorescence from the focal plane is imaged. In present studies, we use the probes 2', 7'-dichlorof luorescein diacetate (H2DCF-DA) and Fluo-3 AM to research reactive oxygen species (ROS) and Ca2+ in mouse 3T3 fibroblasts, respectively. Our results indicate that the distribution of ROS and Ca2+ were clearly seen in mouse 3T3 fibroblasts. Moreover, we acquired and quantified the fluorescence intensity of ROS and Ca2+ with Leica Confocal Software. It was found that the quantified fluorescence intensity of ROS and Ca2+ was 123.30.26 +/- 8.99 and 125.13 +/- 12.16, respectively. Taken together, our results indicate that it is a good method to research the distribution and fluorescence intensity of ROS and Ca2+ in cultured cells with confocal microscope.

To get maximum value added products, quality product monitoring is the most fundamental requirement. Pro-duction of agriculture products can be minimized due to many of the reasons. The fundamental key factor of the quality reduction is the diseases or fungal infection present in the plants. Consequently controlling the diseases or infection in plants require substantially enhancement of the quality production. These infections can lead to severe damage to the rice crop production. Diseases present in rice plants have a critical effect on crop production and accurate detection of disease is the only way to mitigate their effects on the plants. It is a complex task to accurately recognize the disease manually. Early detection and apt remedies is important to expediting the healthy production of the rice plant in order to supply adequately. It also provides foodsecurity to the promptly growing population. The current review addresses the present and projected machine vision approaches for detecting rice disorders. Various techniques have been used to detect the disease present in rice crops is discussed in this paper also associated limitation is also presented. As a result, thispaper discussed the non-destructive and possible applications of machine vision techniques for rice disease diagnosis in depth. © 2022 IEEE.
