This source code is implementation of PIDGIN system from the paper PIDGIN: Ontology Alignment using WebText as Interlingua[http://dl.acm.org/citation.cfm?id=2505559].

The directory structure is given below. Each directory contains source code relating to running code in that directory.

PIDGIN:

- freebase
    Contains source related to running freebase server and creating graph portion corresponding to Freebase entities, relations and noun phrases.

- nell
    Contains source related to running nell server and creating nell portion of graph.

- yago
    Contains source related to running yago server and creating nell portion graph.

- kb_mapping
    Gold mapping for Yago to Nell, Freebase to Nell and KBP to Nell mapping

- learn
    Contains configuration file for junto library which provides implementation of MAD algorithm (https://github.com/parthatalukdar/junto)

- util
    Util functions/source. Currently contains a python script to create seeds for learning

- interlingua
    Config to run SVO solr server and source to index the SVO data. SVO data is provided by Hazy group, CMU[ http://rtw.ml.cmu.edu/resources/svo/nell_hazy_svo_604m.gz]

- graph
    Some rewrite of graph creation process to optimize and avoid code duplication. Still in progress.

Currently all datasets are present on dsr server under /data/d01.
