ICPC Multilingual Collaboratory: a Web- and Unicode-based system for distributed editing/translating/viewing of the multilingual International Classification of Primary Care.

The International Classification of Primary Care (ICPC) is a clinical classification containing 726 clinical concepts, available in over 20 languages, augmented by links to ICD-10 concepts. It is employed in clinical information systems in several European countries, Israel, Japan, and Australia. In translating ICPC, it has been challenging to manage the flow of multilingual information, maintain its quality, and optimize its portability, particularly in light of the numerous character encodings used to represent its content. The ICPC Multilingual Collaboratory (IMC) is a World Wide Web-based environment, created to allow the viewing, maintenance, and translation of ICPC content by a dispersed international editorial staff. Based upon open-source software, it represents ICPC content using the Unicode standard for character encoding. The system implements three interfaces to ICPC data: 1) a password-protected editorial interface which instantiates a hierarchical authority model and communication channels for review and control of content, including a means of up-loading new candidate translations; 2) an openly accessible read-only interface, with e-mail access to the editors (providing another level of content review); and, 3) a management interface for the system administrator. The completed system powerfully demonstrates the ability of the World Wide Web, open-source software, and Unicode to expedite and simplify international multilingual collaboration, even in a world in which Unicode support is incomplete on existing computing platforms.

Multilingual home environment and specific language impairment: a case-control study in Chinese children.

Specific language impairment (SLI) is a common developmental disorder in young children. To investigate the association between multilingual home environment and SLI, we conducted a case-control study in Hong Kong Chinese children over a 4-year period in the Duchess of Kent Children's Hospital. Consecutive medical records of all new referrals below 5 years of age were reviewed and children diagnosed with SLI (case) were compared with those referred with other developmental and behavioural problems who had been assessed as having normal language and overall development (control) using the Griffiths Mental Developmental Scale. SLI was defined as those with a language quotient more than one standard deviation below the mean and below the general developmental quotient in children with normal general developmental quotient, but without neurological or other organic diseases. We used binary and ordinal logistic regression to assess any association between SLI and multilingual exposure at home, adjusting for age and gender of subjects, parental age, education level and occupational status, number of siblings, family history of language delay and main caregiver at home. Multivariable linear regression was used to examine the effect of covariates on the language comprehension and expression standard scores assessed by the Reynell Developmental Language Scale. A total of 326 cases and 304 controls were included. The mean ages of cases and controls were 2.56 and 2.89 years respectively. Boys predominated in both groups (cases, 75.2%; controls, 60.2%). The children were exposed to between one and four languages at home, the major ones being Cantonese Chinese followed by English. The adjusted odds ratio (OR) of SLI was 2.94; [95% confidence interval (CI) 1.82, 4.74] for multilingual compared with monolingual exposure. A significant linear dose-response relationship was found (OR of SLI = 2.58 [1.72, 3.88] for each additional language to which the child was exposed). Male gender (OR = 1.88 [1.24, 2.87]), positive family history (OR = 2.01 [1.17, 3.47]), lower education levels of parents (P = 0.028 for father, P = 0.038 for mother) and lower occupational status of father (P = 0.005) were also risk factors for SLI. Multilingual exposure also significantly reduced the language quotient (P = 0.012) and language comprehension standard score (P = 0.016) of children with SLI, but not of normal children. We concluded that multilingual home environment is associated with SLI with a dose-response relationship. Exposure to multiple languages might adversely affect subsequent language ability.

Crossed aphasia in multilinguals.

Reports of crossed aphasia in single case studies of bilinguals have led to incidence studies of crossed aphasia among larger groups of stroke patients. Among a few others, studies carried out in India (K. R. Nair & Virmani, 1973 Indian Journal of Medical Research, 61, 9; P. Chary, 1986, In Language processing in bilinguals: Psycholinguistic and neuropsychological perspectives) have lent support to the notion of a higher incidence of crossed aphasia among bi- and multilinguals and form major citations in support of the hypothesis that bilingualism could lead to a greater bilateral cerebral representation of languages. This paper reports on the incidence of crossed aphasia in a large unselected population of stroke patients in monolingual and multilingual speakers of South India, which is in agreement with the previous reports of a higher incidence of crossed aphasia in multilinguals. However, along with this high incidence of crossed aphasia a low incidence of sinistrality was also seen. In order to confirm these findings and their significance two further studies were carried out-an incidence study of crossed aphasia in a population of mono- and multilingual aphasics and an incidence study of hand dominance in a normal population. The results and their significance to the issue of crossed aphasia in multilinguals are presented.

[Multilingualism and speech pathology (author's transl)].

Bilingualism, plurilingualism respectively multilingualism can be associated with pathological deviations. Besides hereditary components, it can be observed that exogenic influences such as cerebral injuries etc, may render more difficult multilingualism or even prevent multilingualism. It is the task of the phoniatry to recognize and to deal with this problem. For example, the following situations were explained in terms of recognition, symptoms, and treatment of the communicational disease via multilingualism from the point of phoniatrical-logopaedical view: delayed speech and language development; stammering and dysgrammatism; stuttering; legastheny, and within the framework of hearing disorders. The study is to be conceived as reference for the specialized otorhinolaryngological physician, the problem of multilingualism to comprehend in view of verbal communication disorders.

Multilingual biomedical dictionary.

We present a unique technique to create a multilingual biomedical dictionary, based on a methodology called Morpho-Semantic indexing. Our approach closes a gap caused by the absence of free available multilingual medical dictionaries and the lack of accuracy of non-medical electronic translation tools. We first explain the underlying technology followed by a description of the dictionary interface, which makes use of a multilingual subword thesaurus and of statistical information from a domain-specific, multilingual corpus.

Multilingualism and dyslexia: challenges for research and practice.

Over the last two decades there has been an expansion of activity and substantial progress in research on dyslexia and research on bilingualism and multilingualism. But the study of dyslexia has generally focused on monolingual learners and the study of bilingualism has tended to focus on speakers who do not have special educational needs. This paper will review the strands of research to date that have a bearing on multilingualism and dyslexia and attempt to identify the major challenges that face researchers and teachers. A satisfactory response cannot be developed without a full understanding of the impact that dyslexia has on language learning and the impact that multilingualism has on literacy learning.

Bilingual and multilingual language processing.

This chapter addresses the interesting question on the neurolinguistics of bilingualism and the representation of language in the brain in bilingual and multilingual subjects. A fundamental issue is whether the cerebral representation of language in bi- and multilinguals differs from that of monolinguals, and if so, in which specific way. This is an interdisciplinary question which needs to identify and differentiate different levels involved in the neural representation of languages, such as neuroanatomical, neurofunctional, biochemical, psychological and linguistic levels. Furthermore, specific factors such as age, manner of acquisition and environmental factors seem to affect the neural representation. We examined the question whether verbal memory processing in two unrelated languages is mediated by a common neural system or by distinct cortical areas. Subjects were Finnish-English adult multilinguals who had acquired the second language after the age of ten. They were PET-scanned whilst either encoding or retrieving word pairs in their mother tongue (Finnish) or in a foreign language (English). Within each language, subjects had to encode and retrieve four sets of 12 visually presented paired word associates which were not semantically related. Two sets consisted of highly imaginable words and the other two sets of abstract words. Presentation of pseudo-words served as a reference condition. An emission scan was recorded after each intravenous administration of O-15 water. Encoding was associated with prefrontal and hippocampal activation. During memory retrieval, precuneus showed a consistent activation in both languages and for both highly imaginable and abstract words. Differential activations were found in Broca's area and in the cerebellum as well as in the angular/supramarginal gyri according to the language used. The findings advance our understanding of the neural representation that underlies multiple language functions. Further studies are needed to elucidate the neuronal mechanisms of bi/multilingual language processing. A promising perspective for future bi/multilingual research is an integrative approach using brain imaging studies with a high spatial resolution such as fMRI, combined with techniques with a high temporal resolution, such as magnetoencephalography (MEG).

Predicting Lexical Relations between Biomedical Terms: towards a Multilingual Morphosemantics-based System.

This paper addresses the issue of how semantic information can be automatically assigned to compound terms, i.e. both a definition and a set of semantic relations. This issue is particularly crucial when elaborating multilingual databases and when developing cross-language information retrieval systems. The paper shows how morpho-semantics can contribute in the constitution of multilingual lexical networks in biomedical corpora. It presents a system capable of labelling terms with morphologically related words, i.e. providing them with a definition, and grouping them according to synonymy, hyponymy and proximity relations. The approach requires the interaction of three techniques: (1) a la morphosemantic parser, (2) a multilingual table defining basic relations between word roots, and (3) a set of language-independant rules to draw up the list of related terms. This approach has been fully implemented for French, on an about 29,000 terms biomedical lexicon, resulting to more than 3,000 lexical families.

Interchanging lexical information for a multilingual dictionary.

OBJECTIVE: To facilitate the interchange of lexical information for multiple languages in the medical domain. To pave the way for the emergence of a generally available truly multilingual electronic dictionary in the medical domain. METHODS: An interchange format has to be neutral relative to the target languages. It has to be consistent with current needs of lexicon authors, present and future. An active interaction between six potential authors aimed to determine a common denominator striking the right balance between richness of content and ease of use for lexicon providers. RESULTS: A simple list of relevant attributes has been established and published. The format has the potential for collecting relevant parts of a future multilingual dictionary. An XML version is available. CONCLUSION: This effort makes feasible the exchange of lexical information between research groups. Interchange files are made available in a public repository. This procedure opens the door to a true multilingual dictionary, in the awareness that the exchange of lexical information is (only) a necessary first step, before structuring the corresponding entries in different languages.

MARVIN, multi-agent softbot to retrieve multilingual medical information on the Web.

The World-Wide Web is an unstructured, multimedia and multilingual information network. While most efforts have addressed the structuring issue, very few attempts have been proposed to provide support for multilingual information retrieval. Yet, medical information is now available all over the world. The MARVIN (Multi-Agent Retrieval Vagabond on Information Network) softbot and its associated medical search engine MedHunt (Medical Hunter) are a solution for helping people, who only understand a few languages, to access multilingual information.

Use of functional MR to map language in multilingual volunteers.

PURPOSE: To use functional MR imaging to compare brain activation during processing of languages in which multilingual volunteers are fluent with brain activation during processing of languages in which they are not fluent. METHODS: Echoplanar images were obtained for five right-handed male multilingual subjects who performed a language task in three languages, one of which was a language in which the subject was not fluent. The functional MR technique included echoplanar images obtained at 1 per second during cycles of rest and performance of the task, from which functional images were processed by means of cross-correlation analysis. The numbers of active pixels in each volunteer and for each language were compared. RESULTS: Activation was noted in the left frontal lobe in all subjects performing language tasks. In each subject, the number of activated pixels was greatest for the language in which the subject was least fluent. CONCLUSION: Functional MR imaging shows differences in the processing of different languages in multilingual volunteer subjects, depending on the level of fluency in the language, and it is an effective functional imaging method for studying the processing of different languages.

Language experience and right hemisphere tasks: the effects of scanning habits and multilingualism.

This study explores the effects of multilingualism and reading scanning habits on right hemisphere (RH) abilities. Native Hebrew speakers and Arabic-Hebrew bilinguals performed three tasks. Experiment 1 employed an odd/even decision paradigm on lateralized displays of bar graphs. Both groups of subjects displayed the expected LVFA within the range previously reported for readers of English. Experiment 2 consisted of a chair identification task designed to tap asymmetry of hemispheric arousal and a chimeric face task designed to tap RH specialization for facial emotion. Neither scanning habits nor language experience affected performance on the chair task. Scanning habits seem to have affected performance on the chimeric faces task: there was no preference for the left smile in these right-to-left readers, as opposed to previous results in the literature using left-to-right readers. Correlations between measures from the three tasks and all the subject's scores on an English proficiency test and on a Hebrew test for the bilinguals reveal tentative relationships between proficiency in a second language and RH abilities. The results do not support the hypothesis that multilingualism can affect the manner in which these nonlanguage tasks are subserved by the RH. They do support the hypothesis that scanning habits particular to specific languages can affect performance asymmetries on some nonlanguage tasks that have been posited to reflect RH specialization.

Automatic processing of multilingual medical terminology: applications to thesaurus enrichment and cross-language information retrieval.

OBJECTIVES: We present in this article experiments on multi-language information extraction and access in the medical domain. For such applications, multilingual terminology plays a crucial role when working on specialized languages and specific domains. MATERIAL AND METHODS: We propose firstly a method for enriching multilingual thesauri which extracts new terms from parallel corpora, and secondly, a new approach for bilingual lexicon extraction from comparable corpora, which uses a bilingual thesaurus as a pivot. We illustrate their use in multi-language information retrieval (English/German) in the medical domains. RESULTS: Our experiments show that these automatically extracted bilingual lexicons are accurate enough (85% precision for term extraction) for semi-automatically enriching mono- or bi-lingual thesauri such as the universal medical language system, and that their use in cross-language information retrieval significantly improves the retrieval performance (from 22 to 40% average precision) and clearly outperforms existing bilingual lexicon resources (both general lexicons and specialized ones). CONCLUSION: We show in this paper first that bilingual lexicon extraction from parallel corpora in the medical domain could lead to accurate, specialized lexicons, which can be used to help enrich existing thesauri and second that bilingual lexicons extracted from comparable corpora outperform general bilingual resources for cross-language information retrieval.

Automatic lexeme acquisition for a multilingual medical subword thesaurus.

PURPOSE: We present a method for the automated acquisition of a multilingual medical lexicon (for Spanish, French and Swedish) to be used within the framework of a medical cross-language text retrieval system. METHODS: For the lexical acquisition process, we incorporate seed lexicons and lists of trusted term translations derived from the UMLS Metathesaurus. The seed lexicons for Spanish, French and Swedish are automatically generated from (previously manually constructed) Portuguese, German and English sources by simple string transformations. Lexical and semantic hypotheses are then validated by processing pairs of term translations. In a last step, we use the cleaned list of "approved" translations in order to augment, step by step, the target dictionaries by processing the parallel corpora in terms of co-occurrence patterns of hypothesized translation equivalents which cannot be derived by simple character substitutions. RESULTS: An existing multilingual lexicon for the medical domain with about 60,000 entries for English, German, and Portuguese was automatically augmented by more then 17,000 new lexemes for Spanish, French, and Swedish. CONCLUSIONS: Our approach constitutes a promising method for the automated creation of new lexicon entries and their linkage to semantic identifiers.

Dentist-patient communication in the multilingual dental setting.

BACKGROUND: Communication between dentists and patients can be exceptionally challenging when the patient and the dentist do not speak the same language, as is frequently the case in multicultural Australia. The aim of this study was to describe the issues involved in dealing with limited-English speaking patients in order to formulate recommendations on how to improve dental communication. METHODS: A cross sectional study was performed using a postal survey to Australian Dental Association member dental practitioners in Western Australia. Responses were collated and data analysis was performed using SPSS 11.5 for Windows. RESULTS: Most respondents encounter language-related communication barriers weekly or monthly, and the most satisfactory method of communication is informal interpreters. Despite reporting satisfaction working with professional chairside interpreters or dental staff interpreters, most respondents did not use them. The most common alternative communication methods were diagrams and models. Endodontics and periodontics provided the greatest challenge in communication. Informed consent was reportedly compromised due to language barriers by 29 per cent of respondents. Recommendations to improve communication included access to interpretation services, dentist technique/attitude to communication and patient preparedness for English-speaking encounters. CONCLUSIONS: Many respondents do not utilize the preferential communication methods, creating a potential compromise to both informed consent and the patients' best interests. The use of professional interpreters is recommended, and discussion should be supplemented with means of non-verbal communication. Dentists require access to lists of multilingual dentists and greater awareness of interpretation services to improve multilingual dentist-patient communication.

Intraoperative language localization in multilingual patients with gliomas.

OBJECTIVE: Intraoperative localization of speech is problematic in patients who are fluent in different languages. Previous studies have generated various results depending on the series of patients studied, the type of language, and the sensitivity of the tasks applied. It is not clear whether languages are mediated by multiple and separate cortical areas or shared by common areas. Globally considered, previous studies recommended performing a multiple intraoperative mapping for all the languages in which the patient is fluent. The aim of this work was to study the feasibility of performing an intraoperative multiple language mapping in a group of multilingual patients with a glioma undergoing awake craniotomy for tumor removal and to describe the intraoperative cortical and subcortical findings in the area of craniotomy, with the final goal to maximally preserve patients' functional language. METHODS: Seven late, highly proficient multilingual patients with a left frontal glioma were submitted preoperatively to a battery of tests to evaluate oral language production, comprehension, and repetition. Each language was tested serially starting from the first acquired language. Items that were correctly named during these tests were used to build personalized blocks to be used intraoperatively. Language mapping was undertaken during awake craniotomies by the use of an Ojemann cortical stimulator during counting and oral naming tasks. Subcortical stimulation by using the same current threshold was applied during tumor resection, in a back and forth fashion, and the same tests. RESULTS: Cortical sites essential for oral naming were found in 87.5% of patients, those for the first acquired language in one to four sites, those for the other languages in one to three sites. Sites for each language were distinct and separate. Number and location of sites were not predictable, being randomly and widely distributed in the cortex around or less frequently over the tumor area. Subcortical stimulations found tracts for the first acquired language in four patients and for the other languages in three patients. Three of these patients decreased their fluency immediately after surgery, affecting the first acquired language, which fully recovered in two patients and partially in one. The procedure was agile and well tolerated by the patients. CONCLUSION: These findings show that multiple cortical and subcortical language mapping during awake craniotomy for tumor removal is a feasible procedure. They support the concept that intraoperative mapping should be performed for all the languages in which the patient is fluent in to preserve functional integrity.

An English-language clinic-based literacy program is effective for a multilingual population.

OBJECTIVE: To assess the effectiveness of a clinic-based pediatric literacy intervention on a multilingual population. BACKGROUND: Clinic-based literacy interventions are effective among English- and Spanish-speaking children. No data exist for multilingual populations. SETTING: Pediatric clinic in an urban county hospital. Design/Methods. Reading practices of 2 cross-sectional groups were assessed by standardized interview before and after the intervention. The intervention consisted of waiting-room volunteers reading to children, literacy counseling, and gift of a children's book at each well-child visit from 6 months to 5 years. Outcomes were assessed separately for primary English-speaking and primary non-English-speaking families. RESULTS: The baseline (N=85) and postintervention (N=95) groups were similar with respect to child age and sex, parental education, and length of time in the United States. Fourteen languages were represented in total, the most common being English (41%), Somali (28%), Spanish (9%), Vietnamese (7%), Oromo (3%), and Tigrinyan (3%). Compared with baseline, postintervention respondents were more likely to report reading as a favorite activity for the child (10% vs 25%) and parent (18% vs 40%), to read to their child before bed at least weekly (45% vs 71%), and to possess over 10 children's books at home (49% vs 63%). Among English-speaking families (N=30 baseline, N=40 postintervention), weekly bedtime reading increased (63% to 93%), reading as child's favorite activity increased (7% vs 30%), and reading as the parent's favorite activity to do with child increased (33% vs 58%). The proportion of English-speaking families possessing over 10 books at home and those reading with their children at least weekly showed no difference between the baseline and postintervention groups. Among non-English-speaking families (N=55 baseline, N=55 postintervention), weekly bedtime reading increased (36% vs 56%), reading as the parent's favorite activity increased (11% vs 27%), and the number of families to possess >10 children's books in the home increased (31% vs 49%). Reading as child's favorite activity (13% vs 24%) and weekly book sharing (60% vs 76%) showed nonsignificant trends between the non-English-speaking baseline and postintervention groups. CONCLUSIONS: This clinic-based literacy intervention influences home literacy behavior in this multiethnic setting, in both English-speaking and non-English-speaking families. Although efforts should be made to make such programs more appropriate for linguistic minorities, non-English-speaking families do stand to benefit from English-language-oriented programs. literacy, Reach Out and Read, pediatrics, reading, child development.

A data dictionary approach to multilingual documentation and decision support for the diagnosis of acute abdominal pain. (COPERNICUS 555, an European concerted action).

This paper describes the design and development of a multilingual documentation and decision support system for the diagnosis of acute abdominal pain. The work was performed within a multi-national COPERNICUS European concerted action dealing with information technology for quality assurance in acute abdominal pain in Europe (EURO-AAP, 555). The software engineering was based on object-oriented analysis design and programming. The program cover three modules: a data dictionary, a documentation program and a knowledge based system. National versions of the software were provided and introduced into 16 centers from Central and Eastern Europe. A prospective data collection was performed in which 4020 patients were recruited. The software design has been proven to be very efficient and useful for the development of multilingual software.
