| Research Abstract |
To construct example-based Japanese to Sign text translation systems, there is a serious problem that it is difficult to handle ill-formed sentences such that several postpositions are omitted from a Japanes sentence. This project presents a reasoning method for recovering the lost postpositions from ill-formed sentences using a conjunctive table which stored frequencies of the co-occurrence relations of collocations for postpositions and adjacent characters. The frequencies can be computed by training examples. The most appropriate candidate for the recovery is decided by the decision rules derived from the frequencies and conjunctive conditions. This project also describes a synthesis method for sign animations based on verbal descriptions, which is closely related with the organization of an electronic sign dictionary and which has the powerful capabilities for a flexible inverted retrieval and a customization of the sign entries represented as animations. This project shows a prototype system based on this observation, which has a conventional customizing functions and which is available through the internet.
