Entity linking(EL)is the task of determining the identity of textual entity mentions given a predefined knowledge base(KB).Plenty of existing efforts have been made on this task using either"local"information(contextual information of the mention in the text),or"global"information(relations among candidate entities).However,either local or global information might be insufficient especially when the given text is *** get richer local and global information for entity linking,we propose to enrich the context information for mentions by getting extra contexts from the web through web search engines(WSE).Based on the intuition above,two novel attempts are *** first one adds web-searched results into an embedding-based method to expand the mention's local information,where we try two different methods to help generate high-quality web contexts:one is to apply the attention mechanism and the other is to use the abstract extraction *** second one uses the web contexts to extend the global information,i.e.,finding and utilizing more extra relevant mentions from the web contexts with a graph-based ***,we combine the two models we propose to use both extended local and global information from the extra web *** empirical study based on six real-world datasets shows that using extra web contexts to extend the local and the global information could effectively improve the F1 score of entity linking.

Aluminum alloys with ultra-strength and high-toughness are fundamental structural materials applied in the aerospace *** to the intrinsic restriction between strength and toughness,optimizing a desirable combination of these conflicting properties is always challenging in material *** this study,171 sets of data were curated based on the characteristics of high-strength and high-toughness aluminum alloys in the ***,a machine learning design system(MLDS)with a property-oriented design strategy was established to rapidly discover novel aluminum alloys with ductility and toughness indexes(with elongationδ=8%–10%and fracture toughness K_(IC)=33–35 MPa·m^(1/2))comparable to those of current state-of-the-art AA7136 aluminum alloys when the ultimate tensile strength(UTS)exceeded approximately 100 MPa,with values reaching 700–750 *** the MLDS for experimental verification,three typical candidate alloys show satisfactory performance with UTS of 707–736 MPa,δof 7.8%–9.5%,and K_(IC)of 32.2–33.9 MPa·m^(1/2).The high contents of Mg and Zn alloying elements in the novel alloys form abundantη'phases,which produce a significant hardening effect,while the reasonable matching of Cr,Mn,Ti and Zr dispersoids refines the grain *** decreased Cu content compared with that in the AA7136 alloy inhibits the formation of theσphase and S phase,so that the alloys show high toughness.

Chinese Chemical Letters 2009年第10期20卷 1195-1197页

作者： Duo Li Hai shen Yang Qing Cui shen jie Mao Xiao Hua Xu State Key Laboratory of Elemento-Organic Chemistry Nankai University Tlanjin 300071 China

The bacillamide 1 is a new algaecide from the marine bacterium Bacillus sp. SY-1. Its analogues bacillamide 3 and alkaloid 4 were firstly synthesized effectively from D-alanine. The key step was a coupling reaction via the mixed anhydride. All structures were confirmed by IH NMR and 13C NMR. The final compounds were confirmed by 1H NMR, 13C NMR and HRMS and the results are consistent with the reported natural products.

Shell Model Representation as a Substitute of LoD3 for 3D Modeling in CityGML

Geo-Spatial Information Science 2011年第2期14卷 79-84页

The OGC standard for 3D city modeling is widely used in an increasing number of applications. It defines five consecutive Levels of Detail （LoD0 to LoD4 with increasing accuracy and structural complexity）, in which LoD3 includes all exterior appearances and geometrical details and subsequently requires much storage space. A new LoD is introduced as shell model with the exterior shell of the LoD3 model and the opening objects like windows, doors as well as smaller facade objects are projected onto walls. In this paper, a user survey is presented. The results of this survey show that the shell model can give users almost the same visual impression as the LoD3 model. Furthermroe, algorithms are developed to extract the shell model from LoD3 model. Experiments show that this shell model can reduce up to 90% storage of the original LoD3 model. Therefore, on one hand it can be used as a substitute for a LoD3 model for the visualization on small displays. On the other hand, it can be treated as a sub-level of detail （SLoD3） in CityGML, since it retains almost the same amount of information but requires much less storage space.

With the popularity of online payment, how to perform creditcard fraud detection more accurately has also become a hot issue. And withthe emergence of the adaptive boosting algorithm (Adaboost), credit cardfraud detection has started to use this method in large numbers, but thetraditional Adaboost is prone to overfitting in the presence of noisy ***, in order to alleviate this phenomenon, this paper proposes a newidea: using the number of consecutive sample misclassifications to determinethe noisy samples, while constructing a penalty factor to reconstruct thesample weight assignment. Firstly, the theoretical analysis shows that thetraditional Adaboost method is overfitting in a noisy training set, which leadsto the degradation of classification accuracy. To this end, the penalty factorconstructed by the number of consecutive misclassifications of samples isused to reconstruct the sample weight assignment to prevent the classifierfrom over-focusing on noisy samples, and its reasonableness is ***, by comparing the penalty strength of the three different penalty factorsproposed in this paper, a more reasonable penalty factor is ***, in order to make the constructed model more in line with theactual requirements on training time consumption, the Adaboost algorithmwith adaptive weight trimming (AWTAdaboost) is used in this paper, so thepenalty factor-based AWTAdaboost (PF_AWTAdaboost) is finally ***, PF_AWTAdaboost is experimentally validated against other traditionalmachine learning algorithms on credit card fraud datasets and otherdatasets. The results show that the PF_AWTAdaboost method has betterperformance, including detection accuracy, model recall and robustness, thanother methods on the credit card fraud dataset. And the PF_AWTAdaboostmethod also shows excellent generalization performance on other *** the experimental results, it is shown that the PF_AWTAdaboost algorithmhas better classification

作者： Ji-shuai Wang Yang Hu jie shen Xin-yi Huang 阚成友 Department of Chemical Engineering and Key Laboratory of Advanced Materials of Ministry of Education Tsinghua University

Crosslinked x-P（St-MAA） seed latex was first prepared via soap-free emulsion copolymerization of styrene （St） and methyl methacrylic acid （MAA） with divinyl benzene as crosslinker and ammonium persulfate as initiator, and x-P（St-MAA）/x-P（St-NaSS） core/shell latex particles were then synthesized through a novel seeded emulsion copolymerization of St and sodium styrene sulphonate （NaSS） in the presence of water-soluble crosslinker N,N＇-methylene bisacrylamide （BAA） using oil-soluble 2,2-azobis isobutyronitrile as initiator. TEM observation indicated that narrow dispersed core/shell latex particles were obtained, and element analysis showed that NaSS unit content in the whole particle and in the shell reached 22.8 wt% and 51.2 wt%, respectively.
