Generating Domain-Specific Affective Ontology from Chinese Reviews for Sentiment Analysis

Considering the diversities and ambiguities of opinion expressions in Chinese online product reviews,normal sentiment analysis technologies have exposed their inadequateness in both classification accuracy and identifying effectiveness.We propose a novel approach which can easily identify product features and corresponding opinions by building a domain-specific affective ontology and thus mapping comment sentences to the objects defined in the affective ontology.Ontology is created automatically by processing the online reviews;both product features and affective words are presented as nodes which are connected to each other by their semantic relationship.Furthermore,in order to increase the accuracy,we introduce a dynamic polarity detection technique for affective words whose sentimental tendencies are dependent on particular contexts.The experimental results clearly demonstrate the performance improvement of our approach compared with others in real world online product reviews for classification tests.

Feature extraction of search product based on multi-feature fusion-oriented to Chinese online reviews

The increasing Chinese online reviews contain rich product demand information,especially for search products.This study suggests a product feature extraction model from online reviews based on multi-feature fusion named PFEMF(products features extraction based on multi-feature fusion)model.Combining sentence and word characteristics of Chinese online reviews,the model explores the lexical features,frequency features,span features,and semantic similarity features of words.And then,they are fused to identify the features that customers are concerned about most by sequential relationship analysis.The identified product feature provides direction for product innovation and facilitates the product selection for customers.Finally,the study takes iPad Air as an example to prove this model.The results show that the extraction performance of the PFEMF model is superior to the traditional term frequency-inverse document frequency(tf-idf)algorithm,word span algorithm,and semantic similarity algorithm.

Systematic Reviews/Meta-Analyses of Integrative Medicine in Chinese Need Regulation and Monitoring Urgently and Some Suggestions for Its Solutions

With the introduction and development of evidence-based medicine in China, it has been spread rapidly in the area of integrative medicine（IM） and has become a new unique discipline. During almost 20 years, as one of the most important parts of evidence-based IM, systematic review（SR）/meta-analysis（MA） of IM have shown a good development momentum in the aspects of quantity, depth, breadth and influence, but also face the harsh situation of the uncontrolled quantity and quality, especially for SRs in Chinese. Therefore, how to supervise and standardize this area effectively becomes a problem to be solved. Based on the experience both at home and abroad, the authors put forward several kinds of solutions for laying the foundation for further development such as promoting the registration system of SR/MA of IM, effectively setting up the regulatory platform of quality and quantity, launching professional training for SR/MA reviewers, formingqualification registration, developing the data transfer and sharing platform to realize the transparency of evidence process.

Fine-Grained Opinion Mining on Chinese Car Reviews with Conditional Random Field

Nowadays,the Internet has penetrated into all aspects of people's lives.A large number of online customer reviews have been accumulated in several product forums,which are valuable resources to be analyzed.However,these customer reviews are unstructured textual data,in which a lot of ambiguities exist,so analyzing them is a challenging task.At present,the effective deep semantic or fine-grained analysis of customer reviews is rare in the existing literature,and the analysis quality of most studies is also low.Therefore,in this paper a fine-grained opinion mining method is introduced to extract the detailed semantic information of opinions from multiple perspectives and aspects from Chinese automobile reviews.The conditional random field (CRF) model is used in this method,in which semantic roles are divided into two groups.One group relates to the objects being reviewed,which includes the roles of manufacturer,the brand,the type,and the aspects of cars.The other group of semantic roles is about the opinions of the objects,which includes the sentiment description,the aspect value,the conditions of opinions and the sentiment tendency.The overall framework of the method includes three major steps.The first step distinguishes the relevant sentences with the irrelevant sentences in the reviews.At the second step the relevant sentences are further classified into different aspects.At the third step fine-grained semantic roles are extracted from sentences of each aspect.The data used in the training process is manually annotated in fine granularity of semantic roles.The features used in this CRF model include basic word features,part-of-speech (POS) features,position features and dependency syntactic features.Different combinations of these features are investigated.Experimental results are analyzed and future directions are discussed.

Chinese Ethics Review System and Chinese Medicine Ethical Review:Past,Present,and Future

The Chinese medical ethics committee and the ethical review system have made the following achievements： （1） enabled the institutionalization of medical ethics, （2） carried out the ethics review of Chinese medicine （CM） and integrative medicine extensively, （3） trained a large number of ethical professionals, （4） supported and protected the interests of patients and subjects, and （5） ensured the correct direction of biological research and provided ethical defense for the publication of its results. However, at the same time, they are also faced with some new problems and difficulties that need to be resolved in the following ways： （1） to refine the relevant rules of ethical review, （2） to develop the relevant standards of the CM and integrative medicine ethical review, （3） to enhance the independence and authority of ethics committee, （4） to emphasize innovation and to discover and solve new problems, and （5） to increase international exchanges and improve relevant research.

A Systematic Review of RCTs and quasi-RCTs on Traditional Chinese Patent Medicines for Treatment of Chronic Hepatitis B

Traditional Chinese patent medicines (TCPMs) are widely used for treatment of chronic hepatitis B (CHB) in China. To estimate the overall effectiveness of TCPMs for CHB, we performed a systematic review of clinical reports designed as randomized controlled trials (RCTs). One hundred and thirty-eight available RCTs and quasi-RCTs on 62 TCPMs, involving 16,393 patients, were included. The methodological quality of these trials was generally "poor". Few trials (6.52%) reported the methods of randomization correctly. Another common problem was the lack of allocation concealment, proper blinding, and the reporting of lost cases and dropouts. Forty-two trials (30.43%) on 27 TCPMs reported some anti-viral effect of TCPMs. Others reported beneficial aspects, including improvements of liver function (79.71% of the studies), liver fibrosis (29.99%), and CHB symptoms (92.75%). Forty-one articles (29.71%) reported mild adverse events with TCPMs but these occurred infrequently. In summary, the outcome of the report on currently registered TCPMs may be biased due to poor methodology. The data from these trials, therefore, is too weak to use in forming a recommendation for treatment of CHB. Nevertheless, five drugs (Dan Shen agents, Da Huang Zhe Chong pill/capsule, Shuang Hu Qing Gan granule, Fu Zheng Hua Yu granule and Cao Xian Yi Gan capsule) appear to be more effective than the other TCPMs.

Chinese Herbal Medicine Xingnaojing Injection(醒脑静注射液) for Hypoxic Ischemic Encephalopathy in Newborns:A Systematic Review and Meta-Analysis

Objectives： To evaluate the efficacy and safety of Chinese herbal medicine Xingnaojing Injection（醒脑静注射液） for newborns with hypoxic ischemic encephalopathy（HIE）. Methods： Literature was identified by searching the Pub Med, EMBASE, Cochrane Library, Cochrane Central, and four Chinese literature databases from the establishment of database to October in 2013. Relevant reference lists were also screened. Two reviewers independently evaluated the methodological quality of included studies. We also conducted the meta-analysis. Results： Thirteen trials involving 1,169 patients were included. There was no trial reported death or disability at the end of follow-up period. Meta-analysis of 4 trials（n=371） showed that there was no significant difference in the reduction of mortality [risk ratios（RR）=0.48, 95% confidence intervals（CI, 0.21, 1.13）, P=0.09] between the Xingnaojing and control groups. Meta-analysis of 5 trials（n=359） showed that there was significant difference in reducing the major neurodevelopmental disability [RR=0.36, 95% CI（0.19, 0.66）, P=0.001]. Meta-analysis of 6 trials（n=447） showed that there was a significant difference in the author self-defined symptom improvement [RR=1.25, 95% CI（1.14, 1.37）, P〈0.01]. No fatal side-effects were reported. Conclusion： Based on the limited evidence, the routine use of Xingnaojing Injection for treatment of HIE in newborns is not recommended. Further well-conducted trials are justified.

Case-based learning in education of Traditional Chinese Medicine: a systematic review

OBJECTIVE:To assess the effect of case-based learning(CBL)in the education of Traditional Chinese Medicine(TCM).METHODS:The studies concerning TCM courses designed with CBL were included by searching the databases of EBSCO,Pubmed,Science Citation Index,China National Knowledge Infrastructure,Chongqing VIP database.The valid data was extracted in accordance with the included criteria.The quality of the studies was assessed with Gemma Flores-Masteo.RESULTS:A total of 22 articles were retrieved that met the selection criteria:one was of high quality;two were of low quality;the rest were categorized as moderate quality.The majority of the studiesdemonstrated the better effect produced by CBL,while a few studies showed no difference,compared with the didactic format.All included studies confirmed the favorable effect on learners'attitude,skills and ability.CONCLUSION:CBL showed the desirable results in achieving the goal of learning.Compared to didactic approach,it played a more active role in promoting students'competency.Since the quality of the articles on which the study was based was not so high,the findings still need further research to become substantiated.

Toward Evidence-Based Chinese Medicine：Status Quo,Opportunities and Challenges

How to test the treatments of Chinese medicine（CM） and make them more widely accepted by practitioners of Western medicine and the international healthcare community is a major concern for practitioners and researchers of CM.For centuries,various approaches have been used to identify and measure the efficacy and safety of CM.However,the high-quality evidence related to CM that produced in China is still rare.Over the recent years,evidence-based medicine（EBM） has been increasingly applied to CM,strengthening its theoretical basis.This paper reviews the past and present state of CM,analyzes the status quo,challenges and opportunities of basic research,clinical trials,systematic reviews,clinical practice guidelines and clinical pathways and evidence-based education developed or conducted in China,pointing out how EBM can help to make CM more widely used and recognized worldwide.

Traditional Chinese Medicine for Diminished Ovarian Reserve: A Systematic Review and Meta-analysis

Objective To assess the effectiveness and safety of traditional Chinese medicine（TCM）for women with diminished ovarian reserve（DOR）.Methods A literature search was conducted in eight electronic databases for randomized controlled trials.Results Seventeen randomized controlled trials involving 1174 patients were included.Meta-analysis indicated that TCM was superior to Western medicine（WM）in reducing basal serum FSH level[MD=-1.70,95%CI（-2.63,-0.77）;P=0.0004]and FSH/LH（MD=-0.43,95%CI[-0.56,-0.30];P=0.0001）,and the effect was more obvious two months after the last treatment（MD=-4.60,95%CI[-6.26,-2.90],P〈0.000 01 and MD=-0.56,95%CI[-0.85,-0.28],P=0.0001）,and increasing antral follicle count（AFC）（MD=0.44,95%CI[0.04-0.83];P=0.03）.The review also revealed the positive role of CMM as an adjuvant to IVF-ET in improving pregnancy rate（PR=1.75,95%CI[1.25,2.46];P=0.001）.Conclusion TCM,with its unique way of replenishing the kidney,may provide an effective and safe alternative therapy to patients with DOR.

Individual Patient Data Meta-Analysis Is Needed in Chinese Medical Research

Publication biases and collection limitations are the main disadvantages of a traditional meta-analysis based on aggregate patient data（APD）from published articles.Individual patient data（IPD）meta-analysis,as the gold standard of systematic review,is a possible alternative in this context.However,the publications relative to IPD meta-analyses are still rare compared with the traditional ones,especially in the research oriented to Chinese medicine（CM）.In this article,the strengths and detailed functioning of IPD meta-analysis are described.Furthermore,the need for IPD meta-analysis to assess the treatments based on CM was also discussed.Compared with the traditional APD meta-analysis,the IPD meta-analysis might give a more accurate and unbiased assessment and is worth to be recommended to CM researchers.
