PRIME: A System for Multi-lingual Patent Retrieval
Given the growing number of patents filed in multiple countries, users are
interested in retrieving patents across languages. We propose a multi-lingual
patent retrieval system, which translates a user query into the target
language, searches a multilingual database for patents relevant to the query,
and improves the browsing efficiency by way of machine translation and
clustering. Our system also extracts new translations from patent families
consisting of comparable patents, to enhance the translation dictionary
Cross-lingual document retrieval categorisation and navigation based on distributed services
The widespread use of the Internet across countries has increased the need for access to document collections
that are often written in languages different from a user’s native language. In this paper we describe Clarity, a
Cross Language Information Retrieval (CLIR) system for English, Finnish, Swedish, Latvian and Lithuanian.
Clarity is a fully-fledged retrieval system that supports the user during the whole process of query formulation,
text retrieval and document browsing. We address four of the major aspects of Clarity: (i) the user-driven
methodology that formed the basis for the iterative design cycle and framework in the project, (ii) the system
architecture that was developed to support the interaction and coordination of Clarity’s distributed services, (iii)
the data resources and methods for query translation, and (iv) the support for Baltic languages. Clarity is an
example of a distributed CLIR system built with minimal translation resources and, to our knowledge, the only
such system that currently supports Baltic languages
Introduction to the special issue on cross-language algorithms and applications
With the increasingly global nature of our everyday interactions, the need for multilingual technologies to support efficient and efective information access and communication cannot be overemphasized. Computational modeling of language has been the focus of
Natural Language Processing, a subdiscipline of Artificial Intelligence. One of the current challenges for this discipline is to design methodologies and algorithms that are cross-language in order to create multilingual technologies rapidly. The goal of this JAIR special
issue on Cross-Language Algorithms and Applications (CLAA) is to present leading research in this area, with emphasis on developing unifying themes that could lead to the development of the science of multi- and cross-lingualism. In this introduction, we provide the reader with the motivation for this special issue and summarize the contributions of the papers that have been included. The selected papers cover a broad range of cross-lingual technologies including machine translation, domain and language adaptation for sentiment
analysis, cross-language lexical resources, dependency parsing, information retrieval and knowledge representation. We anticipate that this special issue will serve as an invaluable resource for researchers interested in topics of cross-lingual natural language processing.Postprint (published version
