Enhancing a large scale dictionary with a two-level system

چکیده
We present in this paper a morphological analyzer and generator for French that contains a dictionary of 700,000 inflected words called DELAF 1, and a full twolevel system aimed at the analysis of new derivatives. Hence, this tool recognizes and generates both correct inflected forms of French simple words (DELAF lookup procedure) and new derivatives and their inflected forms (two-level analysis). Moreover, a clear distinction is made between dictionary look-up processes and new words analyses in order to clearly identify the analyses that involve heuristic rules. We tested this tool upon a French corpus of 1 , 3 0 0 , 0 0 0 words with significant results (Clemenceau D. 1992). With regards to efficiency, since this tool is compiled in to a unique transducer, it provides a very fast look-up procedure (1,100 words per second) at a low memory cost (around 1.3 Mb in RAM).

Evaluation of Penetration Level of Large-Scale Photovoltaic System on Voltage Stability of Power System
A power system is a nonlinear one. When turbulence occurs in the power system, the stability of the system depends on the initial operating conditions and the nature of the turbulence. Nowadays renewable energy sources including photovoltaic have a key role to meet high demand of modern societies and to maintain voltage of the buses, while they also provide clean electrical energy. However, inc...
متن کاملA New Dictionary Construction Method in Sparse Representation Techniques for Target Detection in Hyperspectral Imagery
Hyperspectral data in Remote Sensing which have been gathered with efficient spectral resolution (about 10 nanometer) contain a plethora of spectral bands (roughly 200 bands). Since precious information about the spectral features of target materials can be extracted from these data, they have been used exclusively in hyperspectral target detection. One of the problem associated with the detect...
متن کاملAccess control in ultra-large-scale systems using a data-centric middleware
The primary characteristic of an Ultra-Large-Scale (ULS) system is ultra-large size on any related dimension. A ULS system is generally considered as a system-of-systems with heterogeneous nodes and autonomous domains. As the size of a system-of-systems grows, and interoperability demand between sub-systems is increased, achieving more scalable and dynamic access control system becomes an im...
متن کاملAn Investigation into Bilingual Dictionary Use: Do the Frequency of Use and Type of Dictionary Make a Difference in L2 Writing Performance?
Bilingual dictionary use in L2 writing test performance has recently been the subject of debate. Opinions differ according to how the trait is understood and whether the system favors the process-oriented or product-oriented views towards the assessment and writing skill. Given the need for more empirical support, this study is aimed at investigating the availability of bilingual dictionary use...
