Obsei is intended to be an automation tool for text analysis need. Obsei consist of -

  • Observer, observes platform like Twitter, Facebook, App Stores, Google reviews, Amazon reviews etc and feed that information to,
  • Analyzer, which perform text analysis like classification, sentiment, translation, PII etc and feed that information to,
  • Informer, which send it to ticketing system, data store etc for further action and analysis.

Current flow -

A future concept (Coming Soon! 🙂)

Email
from obsei.source.email_source import EmailConfig, EmailCredInfo, EmailSource

# initialize email source config
source_config = EmailConfig(
   # List of IMAP servers for most commonly used email providers
   # https://www.systoolsgroup.com/imap/
   # Also, if you're using a Gmail account then make sure you allow less secure apps on your account -
   # https://myaccount.google.com/lesssecureapps?pli=1
   # Also enable IMAP access -
   # https://mail.google.com/mail/u/0/#settings/fwdandpop
   imap_server="imap.gmail.com", # Enter IMAP server

)

# initialize reddit retriever
source = RedditScrapperSource()
Step 4: Configure Analyzer

Note: To run transformers in an offline mode, check transformers offline mode.

Some analyzer support GPU and to utilize pass device parameter. List of possible values of device parameter (default value auto):

  1. auto: GPU (cuda:0) will be used if available otherwise CPU will be used
  2. cpu: CPU will be used
  3. cuda:{id} - GPU will be used with provided CUDA device id

Text Classification

Text classification, classify text into user provided categories.

from obsei.analyzer.classification_analyzer import ClassificationAnalyzerConfig, ZeroShotClassificationAnalyzer

text_analyzer = ZeroShotClassificationAnalyzer(
   model_name_or_path="joeddav/bart-large-mnli-yahoo-answers",
   device = "auto"
)
Sentiment Analyzer

Sentiment Analyzer, detect the sentiment of the text. Text classification can also perform sentiment analysis but if you don't want to use heavy-duty NLP model then use less resource hungry dictionary based Vader Sentiment detector.

from obsei.analyzer.sentiment_analyzer import VaderSentimentAnalyzer

# Vader does not need any configuration settings
analyzer_config=None

# initialize vader sentiment analyzer
text_analyzer = VaderSentimentAnalyzer()
NER Analyzer

NER (Named-Entity Recognition) Analyzer, extract information and classify named entities mentioned in text into pre-defined categories such as person names, organizations, locations, medical codes, time expressions, quantities, monetary values, percentages, etc

from obsei.analyzer.ner_analyzer import NERAnalyzer

# NER analyzer does not need configuration settings
analyzer_config=None

# initialize ner analyzer
# For supported models refer https://huggingface.co/models?filter=token-classification

   model_name_or_path="Helsinki-NLP/opus-mt-hi-en",
   device = "auto"
)
PII Anonymizer
from obsei.analyzer.pii_analyzer import PresidioEngineConfig, PresidioModelConfig, \ 
   PresidioPIIAnalyzer, PresidioPIIAnalyzerConfig

# initialize pii analyzer's config
analyzer_config = PresidioPIIAnalyzerConfig(
   # Whether to return only pii analysis or anonymize text
   analyze_only=False,
   # Whether to return detail information about anonymization decision
   return_decision_process=True
)

# initialize pii analyzer
analyzer = PresidioPIIAnalyzer(
   engine_config=PresidioEngineConfig(
       # spacy and stanza nlp engines are supported
       # For more info refer 
       # https://microsoft.github.io/presidio/analyzer/developing_recognizers/#utilize-spacy-or-stanza
       nlp_engine_name="spacy",
       # Update desired spacy model and language
       models=[PresidioModelConfig(model_name="en_core_web_lg", lang_code="en")]
   )
)
Dummy Analyzer

Dummy Analyzer, do nothing it simply used for transforming input (AnalyzerRequest) to output (AnalyzerResponse) also adding user supplied dummy data.

from obsei.analyzer.dummy_analyzer import DummyAnalyzer, DummyAnalyzerConfig

# initialize dummy analyzer's configuration settings
analyzer_config = DummyAnalyzerConfig()

# initialize dummy analyzer
analyzer = DummyAnalyzer()
Step 5: Configure Sink/Informer
Slack
from obsei.sink.slack_sink import SlackSink, SlackSinkConfig

# initialize slack sink config
sink_config = SlackSinkConfig(
   # Provide slack bot/app token
   # For more detail refer https://slack.com/intl/en-de/help/articles/215770388-Create-and-regenerate-API-tokens
   slack_token="<Slack_app_token>",
   # To get channel id refer https://stackoverflow.com/questions/40940327/what-is-the-simplest-way-to-find-a-slack-team-id-and-a-channel-id
   channel_id="C01LRS6CT9Q"
)

# initialize slack sink
sink = SlackSink()
Zendesk
from obsei.sink.zendesk_sink import ZendeskSink, ZendeskSinkConfig, ZendeskCredInfo

# initialize zendesk sink config
sink_config = ZendeskSinkConfig(
   # For custom domain refer http://docs.facetoe.com.au/zenpy.html#custom-domains
   # Mainly you can do this by setting the environment variables:
   # ZENPY_FORCE_NETLOC
   # ZENPY_FORCE_SCHEME (default to https)
   # when set it will force request on:
   # {scheme}://{netloc}/endpoint
   # provide zendesk domain
   domain="zendesk.com",
   # provide subdomain if you have one
   subdomain=None,
   # Enter zendesk user details
   cred_info=ZendeskCredInfo(
       email="<zendesk_user_email>",
       password="<zendesk_password>"
   )
)

# initialize zendesk sink
sink = ZendeskSink()
Jira
from obsei.sink.jira_sink import JiraSink, JiraSinkConfig

# For testing purpose you can start jira server locally
# Refer https://developer.atlassian.com/server/framework/atlassian-sdk/atlas-run-standalone/

# initialize Jira sink config
sink_config = JiraSinkConfig(
   url="http://localhost:2990/jira", # Jira server url
    # Jira username & password for user who have permission to create issue
   username="<username>",
   password="<password>",
   # Which type of issue to be created
   # For more information refer https://support.atlassian.com/jira-cloud-administration/docs/what-are-issue-types/
   issue_type={"name": "Task"},
   # Under which project issue to be created
   # For more information refer https://support.atlassian.com/jira-software-cloud/docs/what-is-a-jira-software-project/
   project={"key": "CUS"},
)

# initialize Jira sink
sink = JiraSink()
ElasticSearch
from obsei.sink.elasticsearch_sink import ElasticSearchSink, ElasticSearchSinkConfig

# For testing purpose you can start Elasticsearch server locally via docker
# `docker run -d --name elasticsearch -p 9200:9200 -e "discovery.type=single-node" elasticsearch:7.9.2`

# initialize Elasticsearch sink config
sink_config = ElasticSearchSinkConfig(
   # Elasticsearch server hostname
   host="localhost",
   # Elasticsearch server port
   port=9200,
   # Index name, it will create if not exist
   index_name="test",
)

# initialize Elasticsearch sink
sink = ElasticSearchSink()
Http
from obsei.sink.http_sink import HttpSink, HttpSinkConfig

# For testing purpose you can create mock http server via postman
# For more details refer https://learning.postman.com/docs/designing-and-developing-your-api/mocking-data/setting-up-mock/

# initialize http sink config (Currently only POST call is supported)
sink_config = HttpSinkConfig(
   # provide http server url
   url="https://localhost:8080/api/path",
   # Here you can add headers you would like to pass with request
   headers={
       "Content-type": "application/json"
   }
)

# To modify or converting the payload, create convertor class
# Refer obsei.sink.dailyget_sink.PayloadConvertor for example

# initialize http sink
sink = HttpSink()
Logger

This is useful for testing and dry run checking of pipeline.

from obsei.sink.logger_sink import LoggerSink, LoggerSinkConfig
import logging
import sys

logger = logging.getLogger("Obsei")
logging.basicConfig(stream=sys.stdout, level=logging.INFO)

# initialize logger sink config
sink_config = LoggerSinkConfig(
   logger=logger,
   level=logging.INFO
)

# initialize logger sink
sink = LoggerSink()
Step 6: Join and create workflow

source will fetch data from selected the source, then feed that to analyzer for processing, whose output we feed into sink to get notified at that sink.

# Uncomment if you want logger
# import logging
# import sys
# logger = logging.getLogger(__name__)
# logging.basicConfig(stream=sys.stdout, level=logging.INFO)

# This will fetch information from configured source ie twitter, app store etc
source_response_list = source.lookup(source_config)

# Uncomment if you want to log source response
# for idx, source_response in enumerate(source_response_list):
#     logger.info(f"source_response#'{idx}'='{source_response.__dict__}'")

# This will execute analyzer (Sentiment, classification etc) on source data with provided analyzer_config
analyzer_response_list = text_analyzer.analyze_input(
    source_response_list=source_response_list,
    analyzer_config=analyzer_config
)

# Uncomment if you want to log analyzer response
# for idx, an_response in enumerate(analyzer_response_list):
#    logger.info(f"analyzer_response#'{idx}'='{an_response.__dict__}'")

# Analyzer output added to segmented_data
# Uncomment inorder to log it
# for idx, an_response in enumerate(analyzer_response_list):
#    logger.info(f"analyzed_data#'{idx}'='{an_response.segmented_data.__dict__}'")

# This will send analyzed output to configure sink ie Slack, Zendesk etc
sink_response_list = sink.send_data(analyzer_response_list, sink_config)

# Uncomment if you want to log sink response
# for sink_response in sink_response_list:
#     if sink_response is not None:
#         logger.info(f"sink_response='{sink_response}'")
Step 7: Execute workflow Copy code snippets from Step 3 to Step 6 into python file for example example.py and execute following command -
python example.py
