Forest Driven Dependency Analysis Enhanced by Japanese Clause Structure Estimation

چکیده
For applications of the natural language processing, such as spoken translation, it is the most important characteristic to accept various inputs. We analyze a speech input as a sequence of speech fragment and achieve high acceptability. But it is difficult to determine whether each fragment/unit should be interpreted separately or not. This sort of problem is shared by several applications. We regard a clause and dependency structures as one of the clue to solve this type of problem. Because, even in a spoken language domain, a clause represents a syntactic unit and a dependency represents a semantic unit. In this paper, we describe the dependency analysis method on the syntax forest structure enhanced by Japanese clause structure estimation. It also contributes to improve on translation in manual evaluation from 77.8% up to 78.8%.

Capturing Consistency between Intra-clause and Inter-clause Relations in Knowledge-rich Dependency and Case Structure Analysis
We present a method for dependency and case structure analysis that captures the consistency between intra-clause relations (i.e., case structures or predicate-argument structures) and inter-clause relations. We assess intra-clause relations on the basis of case frames and inter-clause relations on the basis of transition knowledge between case frames. Both knowledge bases are automatically acq...
متن کاملIncremental dependency parsing of Japanese spoken monologue based on clause boundaries
In applications of spoken monologue processing such as simultaneous machine interpretation and real-time captions generation, incremental language parsing is strongly required. This paper proposes a technique for incremental dependency parsing of Japanese spoken monologue on a clause-by-clause basis. The technique identifies the clauses based on clause boundaries analysis, analyzes the dependen...
متن کاملExtraction of Drug-Drug Interaction from Literature through Detecting Linguistic-based Negation and Clause Dependency
Extracting biomedical relations such as drug-drug interaction (DDI) from text is an important task in biomedical NLP. Due to the large number of complex sentences in biomedical literature, researchers have employed some sentence simplification techniques to improve the performance of the relation extraction methods. However, due to difficulty of the task, there is no noteworthy improvement in t...
متن کاملDependency Parsing of Japanese Spoken Monologue Based on Clause Boundaries
Spoken monologues feature greater sentence length and structural complexity than do spoken dialogues. To achieve high parsing performance for spoken monologues, it could prove effective to simplify the structure by dividing a sentence into suitable language units. This paper proposes a method for dependency parsing of Japanese monologues based on sentence segmentation. In this method, the depen...
متن کاملDependency parsing of Japanese spoken monologue based on clause-starts detection
A dependency parsing method based on sentence segmentation into clauses has been proposed and confirmed to be effective. In this method, dependency parsing is executed in two stages: at the clause level and the sentence level. However, since a sentence can not be segmented into complete clauses, in the past research, a unit sandwiched between two clause-end boundaries (clause boundary unit) was...
