Unsupervised Open Relation Extraction
We explore methods to extract relations between named entities from free text in an unsupervised setting. In addition to standard feature extraction, we develop a novel method to re-weight word embeddings. We alleviate the problem of features sparsity using an individual feature reduction. Our approach exhibits a significant improvement by 5.8% over the state-of-the-art relation clustering scor...
متن کاملChinese Open Relation Extraction for Knowledge Acquisition
This study presents the Chinese Open Relation Extraction (CORE) system that is able to extract entity-relation triples from Chinese free texts based on a series of NLP techniques, i.e., word segmentation, POS tagging, syntactic parsing, and extraction rules. We employ the proposed CORE techniques to extract more than 13 million entity-relations for an open domain question answering application....
متن کاملOpen Relation Extraction for Polish: Preliminary Experiments
This paper presents preliminary experiments on Open Relation Extraction for Polish. In particular, a variant of a priorart algorithm for open relation extraction for English has been adapted and tested on a set of articles from Polish on-line news. The paper provides initial evaluation results, which constitute the point of departure for in-depth research in this area.
متن کاملOpen Relation Extraction and Grounding
Previous open Relation Extraction (open RE) approaches mainly rely on linguistic patterns and constraints to extract important relational triples from large-scale corpora. However, they lack of abilities to cover diverse relation expressions or measure the relative importance of candidate triples within a sentence. It is also challenging to name the relation type of a relational triple merely b...
متن کاملZORE: A Syntax-based System for Chinese Open Relation Extraction
Open Relation Extraction (ORE) overcomes the limitations of traditional IE techniques, which train individual extractors for every single relation type. Systems such as ReVerb, PATTY, OLLIE, and Exemplar have attracted much attention on English ORE. However, few studies have been reported on ORE for languages beyond English. This paper presents a syntax-based Chinese (Zh) ORE system, ZORE, for ...
