Text Sentiment Classification Based on Mixed Cloud Vector Model Clustering and Kernel Fisher Discriminant

Yujuan Xing,Ping Tan 보안공학연구지원센터 2015 International Journal of Hybrid Information Techno Vol.8 No.9

In today’s world, the web has dramatically changed the way that people express their opinions. People use the internet to express their opinion, attitude, feeling and emotion about films, goods, news etc. It is challenging to automatically classify mass subjectivity comments into different sentiment orientation categories (e.g. positive/negative). Furthermore, the ambiguity and randomness, which are existed in natural language, lead to lower classification accuracy in text sentiment classification. In this paper, we propose a novel chinese text sentiment classification algorithm based on mixed cloud vector model clustering and kernel fisher discriminant. In this algorithm, we firstly analysis the role of cloud model theory in conversion between qualitative concept and quantitative values, and explore a mixed feature cloud model (MFCM) based on cloud model to represent a single document. In MFCM, both effect of different part-of- speech features and ambiguity of sentiment tendency are considered. And then, documents are clustered according to their similarity between MFCM. Finally, kernel fisher discriminant (KFD) is adopted as the classifier to judge views. The experimental results demonstrate that our proposed method outperforms traditional approaches.

Yujuan Su,Fengtian Yang,Bing Wang,Zhi Jia,Zhongfeng Duan 한국지질과학협의회 2018 Geosciences Journal Vol.22 No.1

Low injectivity of sandstone geothermal reservoirs during reinjection of geothermal waste water is a problem generally encountered in China, and has become a main obstacle for sustainable development of the geothermal resources. Over the last few decades, researchers have made much efforts to solve it based on the studies of reinjection schemes, hydrogeology of the reservoirs, well completion, reinjection water disposal techniques, and water-rock interactions focused on precipitation/dissolution reactions during reinjection. These studies have been very helpful in improving the injectivity. However, there are still many problems remaining for further investigations, among which characterization of the complete process of water-rock interactions during reinjection with the change in redox conditions, CO2 partial pressure, non-isothermal transport process of the reinjection water, and the mechanism of release, transport and sedimentation of colloidal particles on reservoir permeability being taken into account are considered to be the most necessary. This paper gives a brief review of the history and state of the art of the research works on reinjection of cooled water into sandstone geothermal reservoirs, and outlooks the research demands in water-rock interactions during reinjection in the future.

Current methods of fabric dyeing have a significant negative effect on the environment via toxic effluent emissions, high water usage, and high energy consumption. We demonstrate, for the first time, low-energy inkjet printing of an ecofriendly and biodegradable pigment derived from widely available spalting fungi with synthesis by-products that are fully biodegradable. Vivid and stable coloration is achieved on polyester and cotton using benign acetone-based and ethanol-based biopigment inks, with no liquid effluent or runoff, and without any synthetic dyes or mordants. We investigate the influence of fabric type, solvent type, and the number of printing passes on the color type, intensity, and uniformity, pigment crystallization, and environmental stability. Greater spatial definition of the printed pigment in inkjet printing effects greater crystallization and more vivid and uniform coloration as compared to drop-casting, the primary method used till date to color fabrics with such fungal biopigments. pH-driven interactions between the fabric, solvent, and biopigment cause solvent-driven changes in color type (from bluish to reddish) and fabric-governed changes in color intensity. The impact of our findings on minimizing the environmental impact of fabric dyeing is discussed.

Purpose: The aim of this study is to explore signal transducer and activator of transcription 3 (STAT3) expression in breast cancer and to analyze the detailed mechanism that STAT3 contributes to the progression of breast cancer. Methods: We retrospectively analyzed the clinicopathologic characteristics and overall survival (OS) of 140 breast cancer patients after curative surgery, and detected STAT3 expression, phosphorylated STAT3 (pSTAT3) expression, Ki-67 expression, vascular endothelial growth factor (VEGF)-C and -D expression in breast cancer tissues, and adjacent nontumor tissues. Survival analysis and relationship analysis were adopted for demonstrated the important mechanism of STAT3 contribution to progression of breast cancer. Results: STAT3 expression, pSTAT3 expression, Ki-67 expression, VEGF-C expression, and VEGF-D expression in breast cancer tissues were significantly higher than those in adjacent nontumor tissues, respectively. With survival analysis, only number of lymph node metastasis (N stage) was identified as the independent predictors of the OS of breast cancer patients. Besides, we demonstrated there was the most prominent correlation between STAT3 expression and lymph node metastasis in breast cancer tissues by using the multinominal regression method. Conclusion: STAT3, a poor survival biomarker potential association with lymph node metastasis, was suitable for predication the OS of breast cancer patients after curative resection.

Chinese Legal System is a kind of continental legal system, which means things relating to rights protection and duties performance shall be provided by the law. In China, there are more than 10,000 laws, regulations and judicial interpretations, which are implemented everyday by the administrative agencies, the courts, the police and other judicial organs. Laws are made by the legislature- the people's congress of China, while regulations are made by the central government, the central departments, the local governments and their administration agencies. Interpretations are made by the Supreme Court, the Supreme Procuratorate,16) the Ministry of Public Security and so on. In China, the legislation system is very complicated, it's much more complicated than the law system itself. This paper made an introduction of the university-enterprise cooperation in China, the legal provisions on Intellectual Property ownership and benefit concerning technology licensing regarding university-enterprise cooperation. It also pointed out a balance on economic interests between the parties engaged in the cooperation is needed.

Objective: Acetate plays an important role in host lipid metabolism. However, the network of acetate-regulated lipid metabolism remains unclear. Previous studies show that mitogen-activated protein kinases (MAPKs) and mechanistic target of rapamycin (mTOR) play a crucial role in lipid metabolism. We hypothesize that acetate could affect MAPKs and/or mTOR signaling and then regulate lipid metabolism. The present study investigated whether any cross talk occurs among MAPKs, mTOR and acetate in regulating lipid metabolism.Methods: The ceramide C6 (an extracellular signaling-regulated kinases 1 and 2 [ERK1/2] activator) and MHY1485 (a mTOR activator) were used to treat rabbit adipose-derived stem cells (ADSCs) with or without acetate, respectively.Results: It indicated that acetate (9 mM) treatment for 48 h decreased the lipid deposition in rabbit ADSCs. Acetate treatment decreased significantly phosphorylated protein levels of ERK1/2 and mTOR but significantly increased mRNA level of hormone-sensitive lipase (HSL). Acetate treatment did not significantly alter the phosphorylated protein level of p38 MAPK and c-Jun aminoterminal kinase (JNK). Activation of ERK1/2 and mTOR by respective addition in media with ceramide C6 and MHY1485 significantly attenuated decreased lipid deposition and increased HSL expression caused by acetate.Conclusion: Our results suggest that ERK1/2 and mTOR signaling pathways are associated with acetate regulated HSL gene expression and lipid deposition.

( Qiang Zhang ),( Yujuan Li ),( Fangxue Xu ),( Mengmeng Zheng ),( Xiaozhi Xi ),( Xuelan Zhang ),( Chunchao Han ) 한국균학회 2017 Mycobiology Vol.45 No.2

Different endophytes isolated from the seeds of Sophora flavescens were tested for their ability to produce matrine production. Response surface methodology (RSM) was applied to optimize the medium components for the endophytic fungus. Results indicated that endophyte Aspergillus terreus had the ability to produce matrine. The single factor tests demonstrated that potato starch was the best carbon source and the combination of peptone and NH₄NO₃ was the optimal nitrogen source for A. terreus. The model of RSM predicted to gain the maximal matrine production at 20.67 μg/L, when the potato starch was 160.68 g/L, peptone was 24.96 g/L and NH₄NO₃ was 2.11 g/L. When cultured in the optimal medium, the matrine yield was an average of 20.63 ± 0.11 μg/L, which was consistent with the model prediction. This study offered an alternative source for the matrine production by endophytic fungus fermentation and may have far-reaching prospect and value.

Changbo Dai,Yujuan Jia,Qing-Lian Wang,Myeong-Hyeon Wang 한국작물학회 2010 한국작물학회 학술발표대회 논문집 Vol.2010 No.04

Chromosome segment substitution lines (CSSLs), in which each line carries a single or a few defined chromosome segment of donor genome and has a pure genetic background from a recurrent genotype, is a fundamental approach to conduct the QTL mapping in order to improve the mapping precision. In the present study, variety ‘ZM36’ (Gossypium. hirsutum) and ‘Hai1’ (Gossypium. Barbadense) were used as recurrent and donor parent to produce a segment substitution lines populations, respectively. The results indicated that most of fiber quality traits, yield-related traits and verticillium wilt traits fit the normal distribution in the Kolmogorov-Smirnov test. In 133 lines of BC4S2:3 generation fiber length longer the recurrent parent has 37, micronaire lower than the recurrent parent has 58, Fiber strength over than the recurrent parent has 34. In 199 individuals of BC4S2:4 generation fiber length longer the recurrent parent has 37, micronaire lower than the recurrent parent has 36, Fiber strength over than the recurrent parent has 49. Fiber length had significantly positive correlation with fiber strength and negative correlation with micronaire, seed index had significantly positive correlation with boll weight and negative correlation with lint percentage, lint percentage had negative correlation with fiber length and strength.
