Survey on Kernel-Based Relation Extraction
نویسندگان
چکیده
Relation extraction refers to the method of efficient detection and identification of prede‐ fined semantic relationships within a set of entities in text documents (Zelenco, Aone, & Ri‐ chardella, 2003; Zhang, Zhou, and Aiti, 2008). The importance of this method was recognized first at the Message Understanding Conference (MUC, 2001) that had been held from 1987 to 1997 under the supervision of DARPA1. After that, the Automatic Content Ex‐ traction (ACE, 2009) Workshop facilitated numerous researches that from 1999 to 2008 had been promoted by NIST2 as a new project. Currently, the workshop is held every year being the greatest world forum for comparison and evaluation of new technology in the field of information extraction such as named entity recognition, relation extraction, event extrac‐ tion, and temporal information extraction. This workshop is conducted as a sub-field of Text Analytics Conference (TAC, 2012) which is currently under the supervision of NIST.

A survey of kernel methods for relation extraction
In this paper we present the main kernel approaches to the problem of relation extraction from unstructured texts. After a brief introduction to the problem and its characterization as a classification task, we present a survey of the methods and techniques used, and the results obtained. We finally suggest some future lines of work, such as the use of information retrieval techniques and the d...
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 کاملAspect-Based Sentiment Analysis Using Tree Kernel Based Relation Extraction
We present an application of kernel methods for extracting relation between an aspect of an entity and an opinion word from text. Two tree kernels based on the constituent tree and dependency tree were applied for aspect-opinion relation extraction. In addition, we developed a new kernel by combining these two tree kernels. We also proposed a new model for sentiment analysis on aspects. Our mod...
متن کاملTree Kernel-Based Relation Extraction with Context-Sensitive Structured Parse Tree Information
This paper proposes a tree kernel with contextsensitive structured parse tree information for relation extraction. It resolves two critical problems in previous tree kernels for relation extraction in two ways. First, it automatically determines a dynamic context-sensitive tree span for relation extraction by extending the widely-used Shortest Path-enclosed Tree (SPT) to include necessary conte...
متن کاملASM Kernel: Graph Kernel using Approximate Subgraph Matching for Relation Extraction
Kernel methods have been widely studied in several natural language processing tasks such as relation extraction and sentence classification. In this work, we present a new graph kernel that is derived from a distance measure described in prior work as Approximate Subgraph Matching (ASM). The classical ASM distance, shown to be effective for event extraction, is not a valid kernel and was prima...
متن کاملStudy of Kernel-Based Methods for Chinese Relation Extraction
In this paper, we mainly explore the effectiveness of two kernelbased methods, the convolution tree kernel and the shortest path dependency kernel, for Chinese relation extraction based on ACE 2007 corpus. For the convolution kernel, the performances of different parse tree spans involved in it for relation extraction are studied. Then, experiments with composite kernels, which are a combinatio...
