glossterm 0.5

glossterm is a pipeline that extracts, lexes, and parses wiktionary data.

Pipeline

In order to generate files for the web app, you need to grab an English Wiktionary dump, put it in data/ and run the following commands.

You can run the commands by doing e.g. go run cmd/gtdump/main.go or running make to install globally available commands that can be run as e.g. gtdump.

1. gtdump downloads Wiktionary dump to en.xml.bz2.

2. gtsplit splits Wiktionary dump into N files so it can be parsed in parallel. N is set to the current number of cores.

3. gtparse parses split files into words.gob and descendants.gob. Use --no-backup after initial change to index to edit index in place and compare to previously committed index.

4. gtresolve reads words.gob and looks up DescendantTrees references in descendants.gob, and inlines them.

5. gtquads generates quads for each word to power graph lookups, e.g. find all descendants for the Latin roots of a given word.

6. gtbeam fetches cognates in parallel using Apache Beam local runner.

7. gtcognates inlines cognates from gtbeam into words.gob

8. gtcompare compares new index to old index. always use to manually verify parsing changes

9. gtindex incrementally indexes (additions, deletions, updates) words in Firestore

Debugging a single word

1. gtpage <word> extracts a single XML page for a given word. Example: gtpage helado

2. gtlex <word.xml> lexes a single XML page for a given word. Example: gtpage hombre | gtlex

3. gtparseword <word.xml> parses a single XML word. Example: gtpage horno | gtparseword

4. gtparseetymtree <word.xml> parses a single etymtree XML page. Example: gtpage Template:etymtree/la/germanus | gtparseetymtree

5. gtdescend <word> shows the descendants from any words mentioned for a given word.

6. gtread <word> reads word from words.gob. Example: gtpage pt/nariz

7. gtsearch <query> searches the index for a given word.
