Using Grammar Rule Clusters for Semantic Relation Classification
نویسنده
چکیده
Automatically-derived grammars, such as the split-and-merge model, have proven helpful in parsing (Petrov et al., 2006). As such grammars are refined, latent information is recovered which may be usable for linguistic tasks besides parsing. In this paper, we present and examine a new method of semantic relation classification: using automaticallyderived grammar rule clusters as a robust knowledge source for semantic relation classification. We examine performance of this feature group on the SemEval 2010 Relation Classification corpus, and find that it improves performance over both more coarse-grained and more fine-grained syntactic and collocational features in semantic relation classification.

Optimum Ensemble Classification for Fully Polarimetric SAR Data Using Global-Local Classification Approach
In this paper, a proposed ensemble classification for fully polarimetric synthetic aperture radar (PolSAR) data using a global-local classification approach is presented. In the first step, to perform the global classification, the training feature space is divided into a specified number of clusters. In the next step to carry out the local classification over each of these clusters, which cont...
متن کاملOil Reservoirs Classification Using Fuzzy Clustering (RESEARCH NOTE)
Enhanced Oil Recovery (EOR) is a well-known method to increase oil production from oil reservoirs. Applying EOR to a new reservoir is a costly and time consuming process. Incorporating available knowledge of oil reservoirs in the EOR process eliminates these costs and saves operational time and work. This work presents a universal method to apply EOR to reservoirs based on the available data by...
متن کاملAn Executive Approach Based On the Production of Fuzzy Ontology Using the Semantic Web Rule Language Method (SWRL)
Today, the need to deal with ambiguous information in semantic web languages is increasing. Ontology is an important part of the W3C standards for the semantic web, used to define a conceptual standard vocabulary for the exchange of data between systems, the provision of reusable databases, and the facilitation of collaboration across multiple systems. However, classical ontology is not enough ...
متن کاملA Weakly-Supervised Rule-Based Approach for Relation Extraction
Resumen Rule-based approaches for information extraction usually achieve good precision values, even if they often need a lot of manual effort to be implemented. In this paper, we present a novel rule-based strategy for semantic relation extraction that takes advantage of partial syntactic parsing in order to simplify the linguistic structures containing instances of semantic relations. We also...
متن کاملA Context-Free Grammar Of French
Summarx. I present here a method that allows one to construct a CF grammar of a natural language that correctly accounts for verbal selection rules. This goes contrary to the prevailing opinion, following Chomsky 5, that such a construction is impossible. My method consists essentially in separating the semantic function of a selection rule, namely, the exclusion of certain noun sub-classes, fr...
