RETA/RETA++

RETA (as it suggests the Relation and Tail for a given head entity) is an end-to-end solution tackling instance completion problem over KGs. It consists of two components: a RETA-Filter and RETA-Grader. More precisely, our RETA-Filter first generates candidate relation-tail pairs for a given head by extracting and leveraging the schema of a KG; our RETA-Grader then evaluates and ranks the candidate relation-tail pairs considering the plausibility of both the candidate triplet and its corresponding schema using a newly-designed KG embedding model.

RETA++ is an the extension of RETA. It systematically integrates the two components by training RETA-Grader on the reduced solution space output by RETA-Filter via a customized negative sampling process, so as to fully benefit from the efficiency of RETA-Filter in solution space reduction and the deliberation of RETA-Grader in scoring candidate triplets. ​

Parameter setting:

In main.py, you can set:

--indir: input file directory

--withTypes: True trains RETA, False trains RETA no type

--epochs: number of training epochs

--batchsize: batch size of training set

--num_filters: number of filters used in the CNN

--embsize: embedding size

--load: load a pre-trained RETA model and evaluate

--learningrate: learning rate

--outdir: where to store RETA model

--num_negative_samples: number of negative samples

--gpu_ids: gpu to be used for train and test the model

--atLeast: beta parameter

--topNfilters: alpha parameter

--buildTypeDictionaries: store dictionaries to speed-up the code

--sparsifier: top-k types for each entity

--entitiesEvaluated: both (evaluate facts where both h and t have types), one (evaluate facts where either h or t have types), none (evaluate facts where both h and t don't have types). In our paper we have computed the weighted average between these three settings.
