Web - template and web app for creating and running Mechanical Turk HITs as External Questions Backend - command line tools for interacting with MTurk API and creating HITs in MTurk RUN ONCE: load_data_to_db.py populates langugages table in database loads data from wikilanguages-pipeline into database to vocabulary and dictionary tables respectively prepare_images_files.py generates images descriptor files for all vocabulary and dictionary items java -Djava.awt.headless=true generateimages sentences.txt segments.txt images #java -Djava.awt.headless=true generateimages test_sentences.txt test_segments.txt ../test_images #java -Djava.awt.headless=true generateimages pilot_sentences.txt pilot_segments.txt ../pilot_images renders PNG files 10MB of images per 1000 words+sentences obama4australia.py generates images for Barack Obama and Australia in all languages #java -Djava.awt.headless=true Str2ImgObama support_sentences.txt support_sequence.txt ../pilot_images/support generate_voc_hits.py creates hittypes in MTurk and populates hittypes table in database generates batches of vocabulary HITs in database based on vocabulary data populates hits table and voc_hits_data tables in database add_voc_hits_to_mturk.py generates HITs in MTurk and reference them to batches of words in database creates HITs in MTurk for every HIT in datbase with empty mturk_hit_id column updates hits table with non-empty mturk_hit_id value generate_synonyms_table.py generates list of synonyms to be used in Synonyms HIT as controls generate_non_synonyms_table.py generates list of non-synonyms to be used in Synonyms HIT as controls RUN CONTINUOUSLY: get_assignments.py tasks retreives all completed assignments from all HITs and loads results into proper hits_results tables (works both for vocabulary and synonyms HITs) generate_syn_hits.py takes processed results from Voc HIT (from vochitsresults table) and populates syn hits and syn hits data table task can be run multiple times without creating duplicates add_syn_hits_to_mturk.py generates HITs in MTurk and reference them to batches in database creates HITs in MTurk for every HIT in datbase with empty mturk_hit_id column updates hits table with non-empty mturk_hit_id value get_assignments.py -- run again to get results of new syn hits revew_step2.py reviews results of step2 (synonyms HITs) grade syn hits results (based on controls) select all assignments pending update in MTurk for each pending assignments grade assignments one-by-one update status in Mturk and create extra assignment for related hit if assignments data was bad (data_quality<=50%) close assignment in database review_step1.py select all syn hits that have 3 assignments completed with data_status>50% each CREATE OR REPLACE VIEW syn_hits_completed AS -- select all syn HITs that have 3 assignments with good quality of data.
