metadata-flatten-extractor
==========================
A method to flatten generated JSON data into timed CSV events in support
of analytic workflows within the `ContentAI
Platform <https://www.contentai.io>`__, published as the extractor
``dsai_metadata_flatten``. There is also a
`pypi package <https://pypi.org/project/contentai-metadata-flatten/>`__
of this package published for easy incorporation in other projects.
1. `Getting Started <#getting-started>`__
2. `Execution <#execution-and-deployment>`__
3. `Testing <#testing>`__
4. `Future Development <#future-development>`__
5. `Changes <#changes>`__
Getting Started
===============
| This library is used as a `single-run executable <#contentai-standalone>`__.
| Runtime parameters can be passed for processing that configure the
returned results and can be examined in more detail in the
`main <main.py>`__ script.
**NOTE: Not all flattening functions will respect/obey properties
defined here.**
- ``force_overwrite`` - *(bool)* - force existing files to be
overwritten (*default=False*)
- ``compressed`` - *(bool)* - compress output CSVs instead of raw write
(*default=True*, e.g. append ‘.gz’)
- ``all_frames`` - *(bool)* - for video-based events, log all instances
in box or just the center (*default=False*)
- ``time_offset`` - *(int)* - when merging events for an asset split into
multiple parts, time in seconds (*default=0*); negative numbers will
cause a truncation (skip) of events happening before the zero time
mark *(added v0.7.1)*
- ``time_offset_source`` - *(str)* - check for this one-line file path with
number of seconds offset according to `time_offset` rules; *(added v1.4.0)*
- ``verbose`` - *(bool)* - verbose input/output configuration printing
(*default=False*)
- ``extractor`` - *(string)* - specify one extractor to flatten,
skipping nested module import (*default=all*, e.g. ``dsai_metadata``)
- ``generator`` - *(string)* - cify one generator for output,
skipping nested module import (``*``=all, empty=none), e.g. ``flattened_csv``)
Generators
==========
CSV Schema (CSV)
----------------
One output of this flattening will be a set of CSV files if the ``flattened_csv``
is enabled as a generator. One file is created for each discovered/input parser/extractor.
The standard schema for these CSV files has the following fields.
- ``time_begin`` = time in seconds of event start
- ``time_end`` = time in seconds of end (may be equal to time_start if
instantaneous)
- ``time_event`` = exact time in seconds (may be equal to time_start if
instantaneous)
- ``source_event`` = source media for event to add granularity for
event inpact (e.g. face, video, audio, speech, image, ocr, script)
- ``tag`` = simple text word or phrase
- ``tag_type`` = descriptor for type of tag; e.g. tag=concept/label/emotion, keyword=special word,
shot=segment, transcript=text, moderation=moderation, word=text/speech word, person=face or skeleton,
phrase=long utterance, face=face emotion/properties, identity=face or speaker recognition,
scene=semantic scenes/commercials/commercial_lead, brand=product or logo mention, emotion=visual or audio sentiment/emotion
- ``score`` = confidence/probability
- ``details`` = possible bounding box or other long-form (JSON-encoded)
details
- ``extractor`` = name of extractor for insight
Example Programmatic Use
------------------------
While this library is primarily used as an extractor in ContentAI, it can
be programmatically called within another extractor to simplify incoming
data into a simple list for analysis. Several of these examples are available
as code examples in the testing scripts.
1. This dictionary-based call example will parse output of the `azure_videoindexer`
and return it as a dictionary only (do not generate CSV or JSON output).
.. code:: python
from contentai_metadata_flatten.main import flatten
dict_result = flatten({"path_content": "content/jobs", "extractor": "azure_videoindexer",
"generator": "", "verbose": True, "path_result": ".", args=[])
2. This argument call example will parse all extractor outputs and generate a CSV.
.. code:: python
from contentai_metadata_flatten.main import flatten
dict_result = flatten(args=["--path_content", "content/jobs/example.mp4",
"--generator", "flattened_csv", "--path_result": "content/flattened")
3. This low-level access to a parser allows more control over which file or directory
is parsed by the library and no generators are called. This call example is the same as
the first example except that it returns a `DataFrame` instead of a dictionary and may
be slightly faster.
.. code:: python
from contentai_metadata_flatten import parsers
import logging
logger = logging.getLogger()
logger.setLevel(logging.INFO)
list_parser = parsers.get_by_name("azure_videoindexer")
parser_instance = list_parser[0]['obj']("content/jobs", logger=logger)
config_default = parser_instance.default_config()
result_df = parser_instance.parse(config_default)
4. Another low-level access to parsers for only certain tag types. This call example allows
the parsing of only certain tag types (below only those of type `identity` and `face`).
.. code:: python
from contentai_metadata_flatten import parsers
import logging
logger = logging.getLogger()
logger.setLevel(logging.INFO)
list_parser = parsers.get_by_type(["face", "identity"])
for parser_obj in list_parser:
parser_instance = parser_obj['obj']("content/jobs", logger=logger)
config_default = parser_instance.default_config()
result_df = parser_instance.parse(config_default)
Return Value
------------
The main function `main.py::flatten` now returns a richer dictionary (*v1.3.0*).
For programatic callers of the function the dictionary object contains a
`data` property (all of the flattened data as a list) and a `generated` property
which contains a list of nested dictionaries indicating generated outptu (if enabled).
An example output below demonstrates the flattened results as well as two enabled generators.
.. code:: shell
{'data': [
{'tag': 'Clock', 'time_begin': 0, 'time_end': 1, 'time_event': 0, 'score': 0.08157, 'details': '{"model": "/m/01x3z"}', 'source_event': 'audio', 'tag_type': 'tag', 'extractor': 'example_extractor'},
{'tag': 'Sine wave', 'time_begin': 0, 'time_end': 1, 'time_event': 0, 'score': 0.07586, 'details': '{"model": "/m/01v_m0"}', 'source_event': 'audio', 'tag_type': 'tag', 'extractor': 'example_extractor'},
{'tag': 'Tick-tock', 'time_begin': 0, 'time_end': 1, 'time_event': 0, 'score': 0.07297, 'details': '{"model": "/m/07qjznl"}', 'source_event': 'audio', 'tag_type': 'tag', 'extractor': 'example_extractor'},
... ]
'generated': [
{'generator': 'flattened_csv', 'path': 'testme/example_extractor.csv.gz'},
{'generator': 'wbTimeTaggedMetadata', 'path': 'testme/wbTimeTaggedMetadata.json.gz'}]
}
Execution and Deployment
========================
This package is meant to be run as a one-off processing tool that
aggregates the insights of other extractors.
command-line standalone
-----------------------
Run the code as if it is an extractor. In this mode, configure a few
environment variables to let the code know where to look for content.
One can also run the command-line with a single argument as input and
optionally ad runtime configuration (see `runtime
variables <#getting-started>`__) as part of the ``EXTRACTOR_METADATA``
variable as JSON.
.. code:: shell
EXTRACTOR_METADATA='{"compressed":true}'
Locally Run on Results
~~~~~~~~~~~~~~~~~~~~~~
For utility, the above line has been wrapped in the bash script
``run_local.sh``.
.. code:: shell
EXTRACTOR_METADATA='$3' EXTRACTOR_NAME=metadata-flatten EXTRACTOR_JOB_ID=1 \
EXTRACTOR_CONTENT_PATH=$1 EXTRACTOR_CONTENT_URL=file://$1 EXTRACTOR_RESULT_PATH=`pwd`/results/$2 \
python -u main.py
This allows a simplified command-line specification of a run
configuration, which also allows the passage of metadata into a
configuration.
*Normal result generation into compressed CSVs (with overwrite).*
.. code:: shell
./run_local.sh data/wHaT3ver1t1s results/
*Result generation with environment variables and integration of results
from a file that was split at an offset of three hours.*
.. code:: shell
./run_local.sh results/1XMDAz9w8T1JFEKHRuNunQhRWL1/ results/ '{"force_overwrite":false,"time_offset":10800}'
*Result generation from a single extractor, with its nested directory
explicitly specified. (added v0.6.1)*
.. code:: shell
./run_local.sh results/dsai_metadata results/ '{"extractor":"dsai_metadata"}'
Local Runs with Timing Offsets
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The script ``run_local.sh`` also searches for a text file called
``timing.txt`` in each source directory. If found, it will offset all
results by the specified number of seconds before saving them to disk.
Also, negative numbers will cause a truncation (skip) of events
happening before the zero time mark. *(added v0.7.1)*
This capability may be useful if you have to manually split a file into
multiple smaller files at a pre-determined time offset (e.g. three hours
-> 10800 in ``timing.txt``). *(added v0.5.2)*
.. code:: shell
echo "10800" > 1XMDAz9w8T1JFEKHRuNunQhRWL1/timing.txt
./run_local.sh results/1XMDAz9w8T1JFEKHRuNunQhRWL1/ results/
Afterwards, new results can be added arbitrarily and the script can be
rerun in the same directory to accomodate different timing offsets.
*Example demonstrating integration of multiple output directories.*
.. code:: shell
find results -type d -d 1 | xargs -I {} ./run_local.sh {} results/

Alternatively, you can pass an image name to reduce rebuilding a docker
instance.
.. code:: shell
docker build -t metadata-deploy
contentai deploy metadata-flatten --cpu 256 --memory 512 -i metadata-deploy
Locally Downloading Results
~~~~~~~~~~~~~~~~~~~~~~~~~~~
You can locally download data from a specific job for this extractor to
directly analyze.
.. code:: shell
contentai data wHaT3ver1t1s --dir data
