With the rapid development of the robotic industry, domestic robots have become increasingly popular. As domestic robots are expected to be personal assistants, it is important to develop a natural language-based human-robot interactive system for end-users who do not necessarily have much programming knowledge. To build such a system, we developed an interactive tutoring framework, named " Holert”, which can translate task descriptions in natural language to machine-interpretable logical forms automatically. Compared to previous works, Holert allows users to teach the robot by further explaining their intentions in an interactive tutor mode. Furthermore, Holert introduces a semantic dependency model to enable the robot to " understand” similar task descriptions. We have deployed Holert on an open-source robot platform, Turtlebot 2. Experimental results show that the system accuracy could be significantly improved by 163.9% with the support of the tutor mode. This system is also efficient. Even the longest task session with 10 sentences can be handled within 0.7 s. 展开更多

This study examines the representation of China’s policy in the media reporting of the South China Sea dispute in The New York Times and The Washington Post by investigating the semantic prosody of the term“China”with a corpus-based approach.The analysis of collocates of China,namely“claim,action,disputes”in the co-text of concordances indicates that media representation of China in US news coverage is associated with negative semantic prosodies that revolve around China’s territorial claims,island construction,and resolution of the dispute.This reveals that the stance of news report is influenced by its social,cultural,and political context. 展开更多

Synonym differentiation has always been a difficulty in English learning.Traditionally,definitions and examples from dictionaries are taken to illustrate shades of differences between synonyms,which fails to provide a comprehensive description of these differences for students to differ synonyms.However,with the large volume,authentic materials,fast and convenient retrieval provided by corpus,the corpus-based synonym differentiation method can make a comprehensive description of synonyms in terms of their distinctive features in frequency distribution,collocation,colligation and semantic prosody.A corpus-based method will be employed to analyze the differences among the three English synonyms“conquer”“overcome”and“surmount”based on the data collected from COCA(Corpus of Contemporary American English),so as to throw new light on synonym differentiation,offering a new way to study synonyms,and to provide references for lexical teaching and second language acquisition. 展开更多

An effective approach is proposed for 3D urban scene reconstruction in the form of point cloud with semantic labeling. Starting from high resolution oblique aerial images,our approach proceeds through three main stages: geographic reconstruction, geometrical reconstruction and semantic reconstruction. The absolute position and orientation of all the cameras relative to the real world are recovered in the geographic reconstruction stage. Then, in the geometrical reconstruction stage,an improved multi-view stereo matching method is employed to produce 3D dense points with color and normal information by taking into account the prior knowledge of aerial imagery.Finally the point cloud is classified into three classes(building,vegetation, and ground) by a rule-based hierarchical approach in the semantic reconstruction step. Experiments on complex urban scene show that our proposed 3-stage approach could generate reasonable reconstruction result robustly and efficiently.By comparing our final semantic reconstruction result with the manually labeled ground truth, classification accuracies from86.75% to 93.02% are obtained. 展开更多

Cloud detection plays a very significant role in remote sensing image processing.This paper introduces a cloud detection method based on super pixel level classification and semantic segmentation.Firstly,remote sensing images are segmented into super pixels.Segmented super pixels compose a super pixel level remote sensing image database.Though cloud detection is essentially a binary classification task,our database is labeled into four categories to improve the generalization ability:thick cloud,cirrus cloud,building,and other culture.Secondly,the super pixel level database is used to train our cloud detection models based on convolution neural network(CNN)and deep forest.Hierarchical fusion CNN is proposed considering super pixel level images contain less semantic information than normal images.Taking full advantage of low-level features like color and texture information,it is more applicable for super pixel level classification.Besides,a distance metric is proposed to refine ambiguous super pixels.Thirdly,an end-to-end cloud detection model based on semantic segmentation is introduced.This model has no restrictions on the input size,and takes less time.Experimental results show that compared with other cloud detection inethods.our proj)osed method acliieves better performance. 展开更多

With the widespread use of smart phones and mobile Internet,social network users have generated massive geo-tagged tweets,photos and videos to form lots of informative trajectories which reveal not only their spatio-temporal dynamics,but also their activities in the physical world.Existing spatial trajectory query studies mainly focus on analyzing the spatio-temporal properties of the users'trajectories,while leaving the understanding of their activities largely untouched.In this paper,we incorporate the semantics of the activity information embedded in trajectories into query modelling and processing,with the aim of providing end users more informative and meaningful results.To this end,we propose a novel trajectory query that not only considers the spatio-temporal closeness but also,more importantly,leverages a proven technique in text mining field,probabilistic topic modelling,to capture the semantic relatedness of the activities between the data and query.To support efficient query processing,we design a hierarchical grid-based index by integrating the probabilistic topic distribution on the substructures of trajectories and their spatio-temporal extent at the corresponding level of the index hierarchy.This specialized structure enables a top-down search algorithm to traverse the index while pruning unqualified trajectories in spatial and topical dimensions simultaneously.The experimental results on real-world datasets demonstrate the good efficiency and scalability performance of the proposed indices and trajectory search methods. 展开更多
