# fuzzycat (wip)
Fuzzy matching publications for [fatcat](https://fatcat.wiki).
* [fuzzycat](https://pypi.org/project/fuzzycat/)
Note: This is currently work-in-progress.
# Use cases
* [ ] take a release entity database dump as JSON lines and cluster releases
(according to various algorithms)
* [ ] take cluster information and run a verification step (misc algorithms)
* [ ] create a dataset that contains grouping of releases under works
* [ ] command line tools to generate cache keys, e.g. to match reference
strings to release titles (this needs some transparent setup, e.g. filling of
a cache before ops)
# Usage
Release clusters start with release entities json lines.
```shell
$ cat data/sample.json | python -m fuzzycat.main cluster -t title > out.json
```
Clustering 1M records (single core) takes about 64s (15K docs/s).
```shell
$ head -1 out.json
{
"c": "release_key_title",
"v": [
"7ufkzsjywzejvjzsyegugradoa",
"harjqexl5vagxc54zjfen5zlve",
"i5jrdoxqmjfs3fk2dcpnqxqb2e",
"i62bo63qqzggjjk7pf77z26djm",
"omo3z5y7qvh6hbl7wjacinsfiq",
"prkik3s5vzejnfe4u26g2vt2wu",
"pyqss6ifnvgqjeqohlampswvkm",
"spr2b23fk5asph7v6shrd6okt4",
"togokylwfvcvzilhnx4jir2hfm",
"us4artv2hbc5bljuwaopquicfu",
"ycargjj4lzddnmyzbh2e22wsii"
],
"k": "裏表紙"
}
```
Using GNU parallel to make it faster.
```
$ cat data/sample.json | parallel -j 8 --pipe --roundrobin python -m fuzzycat.main cluster -t title
```
Interestingly, the parallel variants detects fewer clusters (because data is
split and clusters are searched within each batch).
## Cluster
```shell
usage: fuzzycat command [options] cluster [-h] [--prefix PREFIX]
[--tmpdir TMPDIR] [-P] [-f FILES]
[-t TYPE]
{cluster,verify} ...
positional arguments:
{cluster,verify}
cluster group entities
verify verify groups
optional arguments:
-h, --help show this help message and exit
--prefix PREFIX temp file prefix
--tmpdir TMPDIR temporary directory
-P, --profile profile program
-f FILES, --files FILES
output files
-t TYPE, --type TYPE cluster algorithm: title, tnorm, tnysi
```
