The publication and reuse of intellectual resources using the Web technologies provide no support for us to clip out any portion
of Web pages, to combine them together for their local reuse, nor to publish the newly composed object as a new Web page for
its reuse by other people. This paper shows how the meme-media architecture is applied to the Web to provide such support
for us. This makes the Web work as a shared repository not only for publishing intellectual resources, but also for their
collaborative reediting. We will propose a general framework for clipping arbitrary Web contents as live objects, for defining
IO ports on such a clip, and for the recombination and linkage of such clips based on both the original and some user-defined
relationships among them. In our previous works, we proposed two separate frameworks for these three purposes; one works for
the first two, and the other for the last. Here we will propose a unified framework for these three purposes, as well as its
detailed internal mechanisms. Then we show how it can be easily applied to various legacy Web applications to develop innovative
services. 相似文献

Statistical approaches in speech technology, whether used for statistical language models, trees, hidden Markov models or neural networks, represent the driving forces for the creation of language resources (LR), e.g., text corpora, pronunciation and morphology lexicons, and speech databases. This paper presents a system architecture for the rapid construction of morphologic and phonetic lexicons, two of the most important written language resources for the development of ASR (automatic speech recognition) and TTS (text-to-speech) systems. The presented architecture is modular and is particularly suitable for the development of written language resources for inflectional languages. In this paper an implementation is presented for the Slovenian language. The integrated graphic user interface focuses on the morphological and phonetic aspects of language and allows experts to produce good performances during analysis. In multilingual TTS systems, many extensive external written language resources are used, especially in the text processing part. It is very important, therefore, that representation of these resources is time and space efficient. It is also very important that language resources for new languages can be easily incorporated into the system, without modifying the common algorithms developed for multiple languages. In this regard the use of large external language resources (e.g., morphology and phonetic lexicons) represent an important problem because of the required space and slow look-up time. This paper presents a method and its results for compiling large lexicons, using examples for compiling German phonetic and morphology lexicons (CISLEX), and Slovenian phonetic (SIflex) and morphology (SImlex) lexicons, into corresponding finite-state transducers (FSTs). The German lexicons consisted of about 300,000 words, SIflex consisted of about 60,000 and SImlex of about 600,000 words (where 40,000 words were used for representation using finite-state transducers). Representation of large lexicons using finite-state transducers is mainly motivated by considerations of space and time efficiency. A great reduction in size and optimal access time was achieved for all lexicons. The starting size for the German phonetic lexicon was 12.53 MB and 18.49 MB for the morphology lexicon. The starting size for the Slovenian phonetic lexicon was 1.8 MB and 1.4 MB for the morphology lexicon. The final size of the corresponding FSTs was 2.78 MB for the German phonetic lexicon, 6.33 MB for the German morphology lexicon, 253 KB for SIflex and 662 KB for the SImlex lexicon. The achieved look-up time is optimal, since it only depends on the length of the input word and not on the size of the lexicon. Integration of lexicons for new languages into the multilingual TTS system is easy when using such representations and does not require any changes in the algorithms used for such lexicons. 相似文献

A method for finding the optimal setting for a uniformly-shifting process mean is developed and an algorithm for solution (suitable for microcomputer implementation) is presented. A determination of the number of parts to be made before resetting, and the level to which the process is to be reset is made given costs for improperly sized parts and for process resetting. 相似文献

Athletes engaged in competition, particularly those involved in international competitions such as the Olympics, are increasingly being tested for a greater variety of banned substances; it is not unusual for tests to be conducted for 100 drugs and another 400 as metabolites. Previous studies related to the accuracy of drug testing processes have failed to properly consider the effects of testing for more than one drug. In order to identify appropriate indicators for the multiple-drug case, probability theory and accuracy concepts applicable to testing for multiple drugs are developed and applied to illustrative data. The probability that a drug-free individual will test positive for drug use is shown to be much higher than indicated by previous studies, and it is shown that an increase in the number of drugs tested for yields an approximately proportionate increase in the probability that a positive test result is erroneous. Therefore, while testing for one drug may result in a comfortably low rate of false accusations of drug use, testing for multiple drugs may well result in an unacceptably high rate. Finally, a set of empirical measures is suggested for use in cases of tests for multiple drugs; the measures will provide for comparability among laboratory proficiency studies. 相似文献

In Scandinavia theories and methods for cooperative design tools for the computer supported craftsman have been the topics for intensive research for several years. This paper widens the discussion by taking in the question of CIM and the reshaping of the division of labour, work organisation and manufacturing processes. The paper argues for an evaluation of methods and tools developed for very different aspects of integrated manufacturing. 相似文献

A dynamic workflow framework for mass customization using web service and autonomous agent techniques 总被引:3,自引:1,他引:2

Custom software development and maintenance is one of the key expenses associated with developing automated systems for mass
customization. This paper presents a method for reducing the risk associated with this expense by developing a flexible environment
for determining and executing dynamic workflow paths. Strategies for developing an autonomous agent-based framework and for
identifying and creating web services for specific process tasks are presented. The proposed methods are outlined in two different
case studies to illustrate the approach for both a generic process with complex workflow paths and a more specific sequential
engineering process. 相似文献
