Based on shear strength reduction finite element method, the influence of width of heel plate and toe plate, uniform load, height of retaining wall, parameters of filling on stability of cantilever retaining wall have been analyzed. It is indicated that the fractured surface is the boundary of "protected" and "unprotected" filling soil, which is essentially different with the second fractured surface of planar retaining wall. The stability of retaining wall increased with width of heel plate or toe board or distance of uniform load increased, and decreased with height of retaining wall or value uniform load of increased. It is advised to fill the retaining wall by the soil with low weight, big cohesive strength and big internal friction angle.

With the increasing amount of user generated reference texts in the web, automatic quality assessment has become a key challenge. However, only a small amount of annotated data is available for training quality assessment systems. Wikipedia contains a large amount of texts annotated with cleanup templates which identify quality flaws. We show that the distribution of these labels is topically biased, since they cannot be applied freely to any arbitrary article. We argue that it is necessary to consider the topical restrictions of each label in order to avoid a sampling bias that results in a skewed classifier and overly optimistic evaluation results. We factor out the topic bias by extracting reliable training instances from the revision history which have a topic distribution similar to the labeled articles. This approach better reflects the situation a classifier would face in a real-life application. © 2013 Association for Computational Linguistics.

In this paper, we analyze a novel set of features for the task of automatic edit category classification. Edit category classification assigns categories such as spelling error correction, paraphrase or vandalism to edits in a document. Our features are based on differences between two versions of a document including meta data, textual and language properties and markup. In a supervised machine learning experiment, we achieve a micro-averaged F1 score of 62 on a corpus of edits from the English Wikipedia. In this corpus, each edit has been multi-labeled according to a 21-category taxonomy. A model trained on the same data achieves state-of-the-art performance on the related task of fluency edit classification. We apply pattern mining to automatically labeled edits in the revision histories of different Wikipedia articles. Our results suggest that high-quality articles show a higher degree of homogeneity with respect to their collaboration patterns as compared to random articles. © 2013 Association for Computational Linguistics.

Automatic document summarization is always attractive to computer science researchers. A novel approach is proposed to address this topic and mainly focuses on the summarization of plain documents. Conventional summarization methods do not fully use the inter-sentence relevance that is not preserved during the processing. In contrast, to tackle the problem and incorporate the latent relations among sentences, our approach constructs relevance structures at sentence-level for plain documents and each sentence is scored with a significance value. Accordingly, important sentences "present" themselves automatically, and the summary paragraph is then generated by selecting top-k scored sentences. Convergence of the algorithm is proved, and experiment, which is conducted on two data sets (DUC 2006 and DUC 2007), shows that the proposed model gives convincing results. © Springer-Verlag 2013.

Boosting prediction performance of protein-protein interaction hot spots by using structural neighborhood properties (extended abstract)

17th Annual International Conference on Research in Computational Molecular Biology, RECOMB 2013

Binding of one protein to another in a highly specific manner to form stable complexes is critical in most biological processes, yet the mechanisms involved in the interaction of proteins are not fully clear. The identification of hot spots, a small subset of binding interfaces that account for the majority of binding free energy, is becoming increasingly important in understanding the principles of protein interactions. Despite experiments like alanine scanning mutagenesis and a variety of computational methods have been applied to this problem, comparative studies suggest that the development of accurate and reliable solutions is still in its infant stage. We developed PredHS (Prediction of Hot Spots), a computational method that can effectively identify hot spots on protein binding interfaces by using 38 optimally chosen properties. The optimal combination of features was selected from a set of 324 novel structural neighborhood properties by a two-step feature selection method consisting of a random forest algorithm and a sequential backward elimination method. We evaluated the performance of PredHS using a benchmark of 265 alanine-mutated interface residues (Dataset I) and a trimmed subset (Dataset II) with 10-fold cross validation. Compared with the state of the art approaches, PredHS achieves a significant improvement on the prediction quality, which stems from the new structural neighborhood properties, the novel way of feature generation as well as the selection power of the proposed two-step method. We further validated the capability of our method by an independent test and obtained promising results.

Study on influence of surcharge preloading on deformation of embankment with FEM

Based on nonlinear finite element method, the deformation and stability of embankment influenced by surcharge preloading is analyzed. It is shown that the location of the maximal lateral displacement of embankment is changeable at different construction stages. The location of the maximal lateral displacement is nearer the shoulder of embankment with construction of embankment. The lateral displacement and vertical settlement become larger and stability of embankment become smaller, when the location of surcharge loads nearer the axis of symmetry of embankment. Therefore, in order to accelerate the settlement of embankment during construction, surcharge preloading should be located nearer the axis of symmetry of embankment. © (2013) Trans Tech Publications, Switzerland.

Based on nonlinear finite element method (FEM), the effect of back berm has been systematically studied. It is found that the lateral displacement of embankment could be reduced by back berm effectively, and the stability of embankment increased rapidly with the width of back berm enlarged. There is a critical value of width of back berm, that the stability of embankment is no more increased with the width of back berm enlarged than critical value. © (2013) Trans Tech Publications, Switzerland.

A table-of-contents (TOC) provides a quick reference to a document's content and structure. We present the first study on identifying the hierarchical structure for automatically generating a TOC using only textual features instead of structural hints e.g. from HTML-tags. We create two new datasets to evaluate our approaches for hierarchy identification. We find that our algorithm performs on a level that is sufficient for a fully automated system. For documents without given segment titles, we extend our work by automatically generating segment titles. We make the datasets and our experimental framework publicly available in order to foster future research in TOC generation.
