Improving Spatial Reference in American Sign Language Animation through Data Collection from Native ASL Signers
Authors: Matt Huenerfauth
Venue: Proceedings of the 5th International Conference on Universal Access in Human-Computer Interaction. Part III: Applications and Services (2009)

Many deaf adults in the U.S. have difficulty reading written English text; computer animations of American Sign Language (ASL) can improve these individuals' access to information, communication, and services. Current ASL animation technology cannot automatically generate expressions in which the signer associates locations in space with entities under discussion, nor can it generate many ASL signs whose movements are modified based on these locations. To determine how important such phenomena are to user-satisfaction and the comprehension of animations by deaf individuals, we conducted a study in which native ASL signers evaluated ASL animations with and without entity-representing spatial phenomena. We found that the inclusion of these expressions in the repertoire of ASL animation systems led to a significant improvement in user comprehension of the animations, thereby motivating future research on automatically generating such ASL spatial expressions.
Learning large scale common sense models of everyday life
Authors: William Pentney, Matthai Philipose, Jeff Bilmes, Henry Kautz
Venue: Proceedings of the 22nd national conference on Artificial intelligence - Volume 1 (2007)

Recent work has shown promise in using large, publicly available, hand-contributed commonsense databases as joint models that can be used to infer human state from day-to-day sensor data. The parameters of these models are mined from the web. We show in this paper that learning these parameters using sensor data (with the mined parameters as priors) can improve performance of the models significantly. The primary challenge in learning is scale. Since the model comprises roughly 50,000 irregularly connected nodes in each time slice, it is intractable either to completely label observed data manually or to compute the expected likelihood of even a single lime slice. We show how to solve the resulting semi-supervised learning problem by combining a variety of conventional approximation techniques and a novel technique for simplifying the model called context-based pruning. We show empirically that the learned model is substantially better at interpreting sensor data and an detailed analysis of how various techniques contribute to the performance.

Fuzzy Evaluation on ERP System Implementing Risk Based on Membership Degree Transformation New Algorithm M(1,2,3)
Authors: Hua Jiang
Venue: Proceedings of the 2009 Second International Symposium on Electronic Commerce and Security - Volume 02 (2009)

The implementing risk of ERP systems has much ambiguity, having no quantifiable indicators and evaluation results only are "big", "small", "general" or other qualitative description, so it is reasonable and scientific to apply fuzzy comprehensive evaluation method for the fuzzy evaluation on ERP system implementing risk. The core of fuzzy evaluation is membership degree transformation. But the transformation methods should be questioned, because redundant data in index membership degree is also used to compute object membership degree, which is not useful for object classification. The new algorithm is: using data mining technology based on entropy to mine knowledge information about object classification hidden in every index, affirm the relationship of object classification and index membership, eliminate the redundant data in index membership for object classification by defining distinguishable weight and extract valid values to compute object membership. The new algorithm of membership degree transformation includes three calculation steps which can be summarized as "effective, comparison and composition", which is denoted as M(1,2,3). The paper applied the new algorithm in the fuzzy evaluation of ERP system implementing risk.

Authors: Etienne de Klerk, Renata Sotirov
Venue: Mathematical Programming: Series A and B (2009)

We consider semidefinite programming relaxations of the quadratic assignment problem, and show how to exploit group symmetry in the problem data. Thus we are able to compute the best known lower bounds for several instances of quadratic assignment problems from the problem library: (Burkard et al. in J Global Optim 10:291&#x2013;403, 1997).

High Performance Support of Lustre over Customized HSNI for HPC
Authors: Yufeng Guo, Xuejun Yang, Li Luo, Qiong Li, Lu Liu
Venue: Proceedings of the 8th International Symposium on Advanced Parallel Processing Technologies (2009)

Parallel I/O needs keep pace with the demand of high performance computing applications. I/O bottleneck still is one of the key problems which restrict the development of high performance computer. Object-based storage combines the advantages of SAN and NAS, adopts an object-based interface, and has been a new orientation of massive storage. The trend as such makes it very promising to build a scalable I/O system for highperformance computing through implementation of object-based storage system based on high-performance interconnects. Lustre is a high performance distributed object parallel file system, is being widely studied and applied. Exploiting performance of Lustre depends on supports of high performance interconnects. In this paper, firstly we designed and implemented a customized high performance interconnect chip, HSNI (High performance Storage Network Interface), and introduced the characteristics of HSNI. Then we analyzed the communication features which support high performance of Lustre. Experimental results show that HSNI can greatly exert the performance of Lustre and has a very good scalability, so its very suitable for building the high performance object-based storage systems for high performance computing.
UNIBA: JIGSAW algorithm for word sense disambiguation
Authors: P. Basile, M. de Gemmis, A. L. Gentile, P. Lops, G. Semeraro
Venue: Proceedings of the 4th International Workshop on Semantic Evaluations (2007)

Word Sense Disambiguation (WSD) is traditionally considered an AI-hard problem. A breakthrough in this field would have a significant impact on many relevant web-based applications, such as information retrieval and information extraction. This paper describes JIGSAW, a knowledge-based WSD system that attemps to disambiguate all words in a text by exploiting WordNet senses. The main assumption is that a specific strategy for each Part-Of-Speech (POS) is better than a single strategy. We evaluated the accuracy of JIGSAW on SemEval-2007 task 1 competition. This task is an application-driven one, where the application is a fixed cross-lingual information retrieval system. Participants disambiguate text by assigning WordNet synsets, then the system has to do the expansion to other languages, index the expanded documents and run the retrieval for all the languages in batch. The retrieval results are taken as a measure for the effectiveness of the disambiguation.
The Script-Writer's Dream: How to Write Great SQL in Your Own Language, and Be Sure It Will Succeed
Authors: Ezra Cooper
Venue: Proceedings of the 12th International Symposium on Database Programming Languages (2009)

We show how to translate expressions in a higher-order programming language into SQL queries. Somewhat surprisingly, we show that any suitable expression translates to a single SQL query, where the suitability is determined by a type-and-effect check. Thus, unlike in Hollywood where a script-writer can never be sure a movie sequel will be popular, we show how to be sure that your SQL--written in your own language--will succeed (in being translated).
Run-Time Semantics of a Language for Programming Social Processes
Authors: Juan M. Serrano, Sergio Saugar
Venue: Computational Logic in Multi-Agent Systems: 9th International Workshop, CLIMA IX, Dresden, Germany, September 29-30, 2008. Revised Selected and Invited Papers (2009)

There is a broad range of application domains which can be described under the heading of social process domains: business processes, social networks, game servers, etc. This paper puts forward a programming language approach to the formal specification of social processes, building upon the C+ action description language. Particularly, the paper focuses on the run-time semantics of the language, which is delivered as a core layer of application-independent sorts which make up the abstract machine of the language. The advantages of the presented approach with respect to other state-of-the-art proposals lie in its strong support for modularity and reusability, and hence for the development of large-scale, elaboration tolerant, specifications of social processes.
HIT-WSD: using search engine for multilingual Chinese-English lexical sample task
Authors: PengYuan Liu, TieJun Zhao, MuYun Yang
Venue: Proceedings of the 4th International Workshop on Semantic Evaluations (2007)

We have participated in the Multilingual Chinese-English Lexical Sample Task of SemEval-2007. Our system disambiguates senses of Chinese words and finds the correct translation in English by using the web as WSD knowledge source. Since all the statistic data is obtained from search engine, the method is considered to be unsupervised and does not require any sense-tagged corpus.
Recognition of Protruding Objects in Highly Structured Surroundings by Structural Inference
Authors: Vincent F. Ravesteijn, Frans M. Vos, Lucas J. Vliet
Venue: Proceedings of the 16th Scandinavian Conference on Image Analysis (2009)

Recognition of objects in highly structured surroundings is a challenging task, because the appearance of target objects changes due to fluctuations in their surroundings. This makes the problem highly context dependent. Due to the lack of knowledge about the target class, we also encounter a difficulty delimiting the non-target class. Hence, objects can neither be recognized by their similarity to prototypes of the target class, nor by their similarity to the non-target class. We solve this problem by introducing a transformation that will eliminate the objects from the structured surroundings. Now, the dissimilarity between an object and its surrounding (non-target class) is inferred from the difference between the local image before and after transformation. This forms the basis of the detection and classification of polyps in computed tomography colonography. 95% of the polyps are detected at the expense of four false positives per scan.
Accurate Computation of Zernike Moments Using Non-symmetry Anti-packing Image Representation
Authors: Wei Huang, Fan Xiong, Chuanbo Chen, Mudar Sarem
Venue: Proceedings of the 2009 Asia-Pacific Conference on Information Processing - Volume 02 (2009)

Zernike Moments (ZMs) have been widely used in pattern recognition and image analysis due to their merits of near-zero information redundancy and rotation invariance. However, the discrete sampling error introduced by state-of-the-art algorithms degrades their rotation invariance. In this paper, a novel algorithm for computing the accurate ZMs of binary images is presented. The new algorithm is based on Non-Symmetry Anti-Packing Image Representation (NAIR) and it computes the accurate ZMs of the whole image by summing up the ZMs of all rectangular regions without introducing the discrete sampling error. The experimental results in this paper show that the NAIR-based algorithm for accurate ZMs is faster than the state-of-the-art accurate algorithms.
Laplace-Beltrami eigenvalues and topological features of eigenfunctions for statistical shape analysis
Authors: Martin Reuter, Franz-Erich Wolter, Martha Shenton, Marc Niethammer
Venue: Computer-Aided Design (2009)

This paper proposes the use of the surface-based Laplace-Beltrami and the volumetric Laplace eigenvalues and eigenfunctions as shape descriptors for the comparison and analysis of shapes. These spectral measures are isometry invariant and therefore allow for shape comparisons with minimal shape pre-processing. In particular, no registration, mapping, or remeshing is necessary. The discriminatory power of the 2D surface and 3D solid methods is demonstrated on a population of female caudate nuclei (a subcortical gray matter structure of the brain, involved in memory function, emotion processing, and learning) of normal control subjects and of subjects with schizotypal personality disorder. The behavior and properties of the Laplace-Beltrami eigenvalues and eigenfunctions are discussed extensively for both the Dirichlet and Neumann boundary condition showing advantages of the Neumann vs. the Dirichlet spectra in 3D. Furthermore, topological analyses employing the Morse-Smale complex (on the surfaces) and the Reeb graph (in the solids) are performed on selected eigenfunctions, yielding shape descriptors, that are capable of localizing geometric properties and detecting shape differences by indirectly registering topological features such as critical points, level sets and integral lines of the gradient field across subjects. The use of these topological features of the Laplace-Beltrami eigenfunctions in 2D and 3D for statistical shape analysis is novel.
