Since the Japanese language does not have explicit word boundaries, dictionary lookup should be done, in principle, for all possible substrings

In this paper, we describe a working system for interactive Japanese syntactic anMysis. A human 'user can intervene during parsing to help the sys- ,em to produce. a correct parse tree. Human inl, eractions are limited to the very simple task of h...

We present a new grammatical formalism called Constraint Dependency Grammar (CDG) in which every grammatical rule is given as a constraint on wordto -word modifications. CDG parsing is formalized as a constraint satisfaction problem over a finite ...

We address the problem of automatic recognition of unconstrained handwritten text. Statistical methods, such as hidden Markov models (HMMs) have been used successfully for speech recognition and they have recently been applied to the problem of ha...

Large corpora with part-of-speech tagging play a very important role in recent statisticsbased and example-based natural language processing systems. However, no such corpora have become widely available for Japanese so far. Because the Japanese l...

Abstract Syntax Notation One (ASN.1) is a framework for representing tree structured data. It is widely used in communication protocols (e.g., LDAP), security protocols (e.g., X.509), and so on. ASN.1 is designed for e ciency and the data is packe...
