The performance evaluation of information retrieval systems has achieved a high momentum in the last few years. Basic performance measures of information retrieval systems include precision and recall. While these measures work well in monolingual web retrieval, they are not suitable for CLIR (Cross-lingual Information Retrieval) and MLIR (Multilingual Information Retrieval) where two or more l...

Information Retrieval (IR) is used to store and represent the knowledge and the retrieval of information relevant for a special user query. Multilingual Information Retrieval (MLIR) system helps the users to pose the query in one language and retrieve the documents in more than one language. One of the basic performance measures of IR systems is Precision. While this measure work well in monoli...

Abstract This paper presents HDNN, a proof-of-concept MLIR dialect for cross-platform computing specialized in deep neural networks. As target devices, HDNN supports CPUs, GPUs and TPUs. In this paper, we provide comprehensive description of the dialect, outlining how novel approach aims to solve $$P^3$$ P <mm...

A typical compiler flow relies on a uni-directional sequence of translation/optimization steps that lower the program abstract representation, making it hard to preserve higher-level information across each transformation step. On other hand, modern ISA extensions and hardware accelerators can benefit from compiler’s ability detect raise idioms acceleration instructions or optimized library cal...

In this paper we propose several merging strategies to integrate the result lists of each intermediate run in distributed MLIR. The prediction of retrieval effectiveness was used to adjust the similarity scores of documents in the result lists. We introduced three factors affecting the retrieval effectiveness, i.e., the degree of translation ambiguity, the number of unknown words and the number...

Discrete Fourier Transform (DFT) libraries are one of the most critical software components for scientific computing. Inspired by FFTW, a widely used library DFT HPC calculations, we apply compiler technologies development transform libraries. In this work, introduce FFTc, domain-specific language, based on Multi-Level Intermediate Representation (MLIR), expressing algorithms. We present initia...

We participated in SLIR, BLIR(PLIR) and MLIR subtasks at the NTCIR-4 CLIR task. Our IR system can handle queries and documents in Chinese, English and Japanese. The system utilizes multiple language resources (bilingual dictionaries, parallel corpora and machine translation systems) for query translation. We adopted the pivot language approach for C-J and J-C search using English as a pivot lan...
