We introduce the bilingual dual-coding theory as a model for bilingual mental representation. Based on this model, lexical selection neural networks are implemented for a connectionist transfer project in machine translation. provided evidence for both hypotheses (de Groot and Nas, 1991; Lambert, 1958). Dual-coding theory explains the coexistence of independent and interdependent phenomena with separate but connected structures. The general dual-coding theory hypothesizes that human represents language with dual systems - - the verbal system and the imagery system. . | DUAL-CODING THEORY AND CONNECTIONIST LEXICAL SELECTION Ye-Yi Wang Computational Linguistics Program Carnegie Mellon University Pittsburgh PA 15232 Internet yyw@ Abstract We inưoduce the bilingual dual-coding theory as a model for bilingual mental representation. Based on this model lexical selection neural networks are implemented for a connectionist transfer project in machine translation. Introduction Psycholinguistic knowledge would be greatly helpful as we believe in consưucting an artificial language processing system. As for machine translation we should take advantage of our understandings of 1 how the languages are represented in human mind 2 how the representation is mapped from one language to another 3 how the representation and mapping are acquired by human. The bilingual dual-coding theory Paivio 1986 partially answers the above questions. It depicts the verbal representations for two different languages as two separate but connected logogen systems characterizes the ưanslation process as the activation along the connections between the logogen systems and attributes the acquisition of the representation to some unspecified statistical processes. We have explored an information theoretical neural network Gorin and Levinson 1989 that can acquire the verbal associations in the dual-coding theory. It provides a learnable lexical selection sub-system for a connectionist transfer project in machine translation. Dual-Coding Theory There is a well-known debate in psycholinguistics concerning the bilingual mental representation independence position assumes that bilingual memory is represented by two functionally independent storage and retrieval systems whereas interdependence position hypothesizes that all information of languages exists in a common memory store. Studies on crosslanguage transfer and cross-language priming have This work was partly supported by ARPA and ATR Interpreting Telephony Research Laboratorie. provided evidence for both .
