Portuguese-English Experiments Using Latent Semantic Indexing [chapter]

Viviane Moreira Orengo, Christian Huyck
2003 Lecture Notes in Computer Science  
We have carried out experiments using Portuguese queries to retrieve documents in English.  ...  The approach used was Latent Semantic Indexing, which is an automatic method not requiring dictionaries or thesauri. We describe the methods used along with an analysis of the results obtained.  ...  CLIR using Latent Semantic Indexing Latent Semantic Indexing [1] is a technique developed in 1990 by Dumais, Derweester, Landauer, Furnas and Harshman.  ...

Indian Languages IR using Latent Semantic Indexing

A.P SivaKumar, P Premchand, A Govardhan
2011 International Journal of Computer Science & Information Technology (IJCSIT)  
Retrieving information from different languages may lead to many problems like polysemy and synonymy, which can be resolved by Latent Semantic Indexing (LSI) techniques.  ...  This paper uses the Singular Value Decomposition (SVD) of LSI technique to achieve effective indexing for English and Hindi languages.  ...  By using Latent Semantic Indexing the retrieval rate is 3 times more than the direct Matching. The success rate is 69%. The reference [4] describes Portuguese-English Experiments using LSI.  ...

Validation of the Brazilian Version of the Musculoskeletal Tumor Society Rating Scale for Lower Extremity Bone Sarcoma

Daniel Cesar Seguel Rebolledo, João Ricardo Nickenig Vissoci, Ricardo Pietrobon, Olavo Pires de Camargo, Andre Mathias Baptista
2013 Clinical Orthopaedics and Related Research  
Method The MSTS rating scale for lower limbs was translated from English into Brazilian Portuguese.  ...  Despite its use in several studies in English-speaking countries, its validity for assessing patients in other languages is unknown.  ...  This resulted in a translation of the MSTS rating scale that reflected both semantic and conceptual equivalence to the original English version of the questionnaire.  ...

An automatic linking service of document images reducing the effects of OCR errors with latent semantics

Renato F. Bulcão-Neto, José Camacho-Guerrero, Álvaro Barreiro, Javier Parapar, Alessandra A. Macedo
2010 Proceedings of the 2010 ACM Symposium on Applied Computing - SAC '10  
The LinkDI service extracts and indexes document images content, obtains its latent semantics, and defines relationships among images as hyperlinks.  ...  This paper presents a novel approach to support the automatic generation of relationships among document images by exploiting Latent Semantic Indexing (LSI) and Optical Character Recognition (OCR).  ...  Currently, LinkDI supports documents in English, Spanish and Portuguese.  ...

2012 Joint Seminar on Ontology Research in Brazil / International Workshop on Metamodels, Ontologies and Semantic Technologies  
Particularly, the pair of languages we work in this paper are English and Portuguese. In order to perform query translation we use a statistical machine translation approach.  ...  Our experiments show that the multilingual system is capable of achieving almost the same quality of that obtained by the monolingual system. Resumo.  ...  That is why in order to obtain more efficient vector-space representations, space reduction techniques such as latent semantic indexing and probabilistic latent semantic indexing (Hofmann 1999 ) are applied  ...
