A Novel Feature-based Approach to Chinese Entity Relation Extraction
نویسندگان
چکیده
Relation extraction is the task of finding semantic relations between two entities from text. In this paper, we propose a novel feature-based Chinese relation extraction approach that explicitly defines and explores nine positional structures between two entities. We also suggest some correction and inference mechanisms based on relation hierarchy and co-reference information etc. The approach is effective when evaluated on the ACE 2005 Chinese data set.

Improved-Edit-Distance Kernel for Chinese Relation Extraction
In this paper, a novel kernel-based method is presented for the problem of relation extraction between named entities from Chinese texts. The kernel is defined over the original Chinese string representations around particular entities. As a kernel function, the Improved-Edit-Distance (IED) is used to calculate the similarity between two Chinese strings. By employing the Voted Perceptron and Su...
متن کاملExploring Deep Belief Network for Chinese Relation Extraction
Relation extraction is a fundamental task in information extraction that identifies the semantic relationships between two entities in the text. In this paper, a novel model based on Deep Belief Network (DBN) is first presented to detect and classify the relations among Chinese entities. The experiments conducted on the Automatic Content Extraction (ACE) 2004 dataset demonstrate that the propos...
متن کاملA Novel Approach to Conditional Random Field-based Named Entity Recognition using Persian Specific Features
Named Entity Recognition is an information extraction technique that identifies name entities in a text. Three popular methods have been conventionally used namely: rule-based, machine-learning-based and hybrid of them to extract named entities from a text. Machine-learning-based methods have good performance in the Persian language if they are trained with good features. To get good performanc...
متن کاملChinese Entity Relation Extraction Based on Word Co-occurrence
Chinese entity relation extraction is a part of entity relation extraction. According to entity relation extraction technology and the features of Chinese news corpus, this paper proposes a novel method for Chinese entities relation extraction. The method, named WCORE (word co-occurrence relation extraction), first measures the semantic similarity by word co-occurrence and then adopts pattern m...
متن کاملExploiting the Role of Position Feature in Chinese Relation Extraction
Relation extraction is the task of finding pre-defined semantic relations between two entities or entity mentions from text. Many methods, such as feature-based and kernel-based methods, have been proposed in the literature. Among them, feature-based methods draw much attention from researchers. However, to the best of our knowledge, existing feature-based methods did not explicitly incorporate...
