PPDB: The Paraphrase Database
We present the 1.0 release of our paraphrase database, PPDB. Its English portion, PPDB:Eng, contains over 220 million paraphrase pairs, consisting of 73 million phrasal and 8 million lexical paraphrases, as well as 140 million paraphrase patterns, which capture many meaning-preserving syntactic transformations. The paraphrases are extracted from bilingual parallel corpora totaling over 100 mill...
متن کاملppdb: a plant promoter database
ppdb (http://www.ppdb.gene.nagoya-u.ac.jp) is a plant promoter database that provides promoter annotation of Arabidopsis and rice. The database contains information on promoter structures, transcription start sites (TSSs) that have been identified from full-length cDNA clones and also a vast amount of TSS tag data. In ppdb, the promoter structures are determined by sets of promoter elements ide...
متن کاملAugmenting FrameNet Via PPDB
FrameNet is a lexico-semantic dataset that embodies the theory of frame semantics. Like other semantic databases, FrameNet is incomplete. We augment it via the paraphrase database, PPDB, and gain a threefold increase in coverage at 65% precision.
متن کاملppdb: plant promoter database version 3.0
ppdb (http://ppdb.agr.gifu-u.ac.jp) is a plant promoter database that provides information on transcription start sites (TSSs), core promoter structure (TATA boxes, Initiators, Y Patches, GA and CA elements) and regulatory element groups (REGs) as putative and comprehensive transcriptional regulatory elements. Since the last report in this journal, the database has been updated in three areas t...
متن کاملClassification of Entailment Relations in PPDB
This document outlines our protocol for labeling noun pairs according to the entailment relations proposed by Bill MacCartney in his 2009 thesis on Natural Language Inference. Our purpose of doing this is to build a labelled data set with which to train a classifier for differentiating between these relations. The classifier can be used to assign probabilities of each relation to the paraphrase...
