Frontend
You can visit following pages for this app.
Tagging
http://[ip]:[port]/
is for our hard working taggers to visit.
Admin
http://[ip]:[port]/admin
is a page where you can:
- See the progress of each user.
- Force save the progress, (or it will only save according to
save_frequency
, default 42 entries) - Download the tagged entries
Advanced settings
Validation
You can set minimun verification number: cross_verify_num
, aka, how each entry will be validated, default is 1
If you set cross_verify_num
to 2, and you have 5 taggers, each entry will be seen by 2 taggers
app = ClassifyTask.from_df(
df, text_col="comment",
options=["positive", "negative", "unbiased", "not sure"],
cross_verify_num=2,)
Load History
If your service stopped, you can recover the progress from cache.
Previous cache will be at $HOME/.cache/langhuan/{task_name}
You can change the save_frequency to suit your task, default is 42 entries.
app = NERTask.from_df(
df, text_col="description",
options=["institution", "company", "name"],
save_frequency=128,
load_history=True,
task_name="task_NER_210123_110327"
)
Admin Control
This application assumes internal use within organization, hence the mininum security. If you set admin_control, all the admin related page will require
adminkey
, the key will appear in the console prompt
app = NERTask.from_df(
df, text_col="description",
options=["institution", "company", "name"],
admin_control=True,
)
