Character-based Collocation for Mandarin Chinese
This paper describes a characters-based Chinese collocation system and discusses the advantages of it over a traditiolml word-based systcm. Since wordbreaks are not conventionally marked in Chinese text corpora, a character-based collocation system has the dual advantages of avoiding pre-proccssing distortion and directly accessing sub-lexical information. Furthermore, word-based collocational properties can be obtained through an auxiliary modttle of automatic segmentation. corpora as they are, we ",viii be able to access sub-lexical information without additional cost. To take the full advantage of the nature of texts, reliable tools can also be devised to obtain [exical collocation. In this paper, we ,,viii describe the design and implementation e r a Chinese collocational system that does not require the preprocessing of automatic segmentation but is awe to allow both lexical and sub-lexical information be automatically extracted.

A Chinese Corpus for Linguistic Research
This is a project note on the first stage of the construction of a comprehensive corpus of both Modern and Classical Chinese. The corpus is built with the dual aim of serving as the central database for Chinese language processing and for supporting in-depth linguistic research in Mandarin Chinese.

The Open Language Archives Community and Asian Language Resources
The Open Language Archives Community (OLAC) is a new project to build a worldwide system of federated language archives based on the Open Archives Initiative and the Dublin Core Metadata Initiative. This paper aims to disseminate the OLAC vision to the language resources community in Asia, and to show language technologists and linguists how they can document their tools and data in such a way that others can easily discover them. We describe OLAC and the OLAC Metadata Set, then discuss two key issues in the Asian context: language classification and multilingual resource classification.

Segmentation Standard for Chinese Natural Language Processing
This paper proposes a segmentation standard for Chinese natural language processing. The standard is proposed to achieve linguistic felicity, computational feasibility, and data uniformity. Linguistic felicity is maintained by defining a segmentation unit to be equivalent to the theoretical definition of word, and by providing a set of segmentation principles that are equivalent to a functional definition of a word. Computational feasibility is ensured by the fact that the above functional definitions are procedural in nature and can be converted to segmentation algorithms, as well as by the implementable heuristic guidelines which deal with specific linguistic categories. Data uniformity is achieved by stratification of the standard itself and by defining a standard lexicon as part of the segmentation standard.

On test and diagnostics of flash memories
Embedded flash memory has been widely used in applications that require non-volatile on-chip storage elements. However, test and diagnostics of flash memories needs further investigation so that the overall cost of the products can be reduced. This paper presents the challenges and issues for test and diagnostics of flash memories, based on our recent experiences. We also suggest improvement of the test and diagnosis flow, including design-for-testability (DFT) using built-in self-test (BIST), built-in self-repair (BISR), and failure analysis. In addition, we present a configurable flash memory tester using FPGA for low-cost testing and diagnostics. Experimental results on industrial flash chips justify the effectiveness of our test and diagnostics system.

Performance evaluation of adaptive MPI
Processor virtualization via migratable objects is a powerful technique that enables the runtime system to carry out intelligent adaptive optimizations like dynamic resource management. Charm++ is an early language/system that supports migratable objects. This paper describes Adaptive MPI (or AMPI), an MPI implementation and extension, that supports processor virtualization. AMPI implements virtual MPI processes (VPs), several of which may be mapped to a single physical processor. AMPI includes a powerful runtime support system that takes advantage of the degree of freedom afforded by allowing it to assign VPs onto processors. With this runtime system, AMPI supports such features as automatic adaptive overlapping of communication and computation, automatic load balancing, flexibility of running on arbitrary number of processors, and checkpoint/restart support. It also inherits communication optimization from Charm++ framework. This paper describes AMPI, illustrates its performance benefits through a series of benchmarks, and shows that AMPI is a portable and mature MPI implementation that offers various performance benefits to dynamic applications.

Measures of wireless data performance
There is considerable interest within the industry in specifying the performance of wireless data. In this letter, we review and contrast various performance metrics such as peak rates, average throughput, and user experience. We discuss the relevance of these measures to varying applications such as marketing, planning, and technology comparisons.

On personal data license design and negotiation
Web applications often require users to provide personal information for customization, identification, or completing a transaction. However, the way we disclose our information in current cyberspace does not allow us to control the usage, release and circulation of the information, violating the basic principle of personal information privacy. Online personal data licensing (OPDL) is a framework to bring the control of personal information back to individuals by requiring application and service providers to obtain a license from a person before collecting, processing, and using his personal information. In this paper we present the license design and automation of the license negotiation process.
