The purpose of this paper is to overview research efforts at the NTCIR-5 CLIR task, which is a project of large-scale retrieval experiments on cross-lingual information retrieval (CLIR) of Chinese, Japanese, Korean, and English. The project has three sub-tasks, multi-lingual IR (MLIR), bilingual IR (BLIR), and single language IR (SLIR), in which many research groups from over ten countries are ...

The purpose of this paper is to overview research efforts at the NTCIR-6 CLIR task, which is a project of large-scale retrieval experiments on cross-lingual information retrieval (CLIR) of Chinese, Japanese, Korean, and English. The project has three sub-tasks, multi-lingual IR (MLIR), bilingual IR (BLIR), and single language IR (SLIR), in which many research groups from ten countries or region...

Cross-language information retrieval (CLIR) and multilingual information retrieval (MLIR) techniques have been widely studied, but they are not often applied to and evaluated for Web applications. In this paper, we present our research in developing and evaluating a multilingual English-Chinese Web portal in the business domain. A dictionary-based approach has been adopted that combines phrasal...

Multilingual information is overflowing on internet these days. This increasing diversity of web pages in almost every popular language in the world should enable the user to access information in any language of his choice. But sometimes it is difficult for a user to write her request in a language which she could easily read and understand. This makes cross-language information retrieval (CLI...

در این مقاله، به بررسی اثر پارامترهای گوناگون بر شکل تپ‌های گسیلی لیزر 2CO تپی پرداخته شده است. راستا، عوامل مختلفی مانند: فشار گاز و هم‌­چنین طول تشدیدگر تغییر داده شدند هر حالت به‌همراه اندازه انرژی آن‌ها ثبت گردیدند. نتایج نشان می‌­دهد که با افزایش گاز، به‌شدت می‌یابد، به‌گونه‌ای 2 برابر 3 شدن فشار، 5 برابر، پهنای زمانی تپ‌ها نیم یک‌سوم زمان برساخت آن‌­ها نیز 9/0 7/0 اندازه‌های اولیه‌ی خود م...

In this work, a new method based on the modified Enskog theory (MET) is presented for calculation of transport properties at high densities ρ > ρc). The main limitation of using the MET is lack of experimental data for co-volume, b0. We have substituted b0 from hard sphere (HS) theory nd zero density transport properties from the kinetic theory of gases for HS in the MET expression, because of ...
