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, News, Website 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, dataframe etc for further action and analysis.

Current flow

Future concept (Coming Soon! 🙂)

Use cases

Obsei use cases are following, but not limited to -

• Automatic customer issue creation based on sentiment analysis (reduction of MTTD)
• Proper tagging of ticket based for example login issue, signup issue, delivery issue etc (reduction of MTTR)
• Checking effectiveness of social media marketing campaign
• Extraction of deeper insight from feedbacks on various platforms
• Research purpose

Demo

We have a minimal streamlit based UI that you can use to test Obsei.

Watch: Obsei UI Demo

To test remotely, just open: Obsei Demo Link (Note: Due to rate limit sometime Streamlit demo might not work, hence please use docker image locally.)

To test locally, just run

docker run -d --name obesi-ui -p 8501:8501 obsei/obsei-ui-demo

# You can find the UI at http://localhost:8501

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 # initialize classification analyzer config # It can also detect sentiments if "positive" and "negative" labels are added. analyzer_config=ClassificationAnalyzerConfig( labels=["service", "delay", "performance"], ) # initialize classification analyzer # For supported models refer https://huggingface.co/models?filter=zero-shot-classification text_analyzer = ZeroShotClassificationAnalyzer( model_name_or_path="typeform/mobilebert-uncased-mnli", 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 text_analyzer = NERAnalyzer( model_name_or_path="elastic/distilbert-base-cased-finetuned-conll03-english", device = "auto" )

Translator from obsei.analyzer.translation_analyzer import TranslationAnalyzer # Translator does not need analyzer config analyzer_config = None # initialize translator # For supported models refer https://huggingface.co/models?pipeline_tag=translation analyzer = TranslationAnalyzer( 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 (TextPayload) to output (TextPayload) 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()

Pandas DataFrame from pandas import DataFrame from obsei.sink.pandas_sink import PandasSink, PandasSinkConfig # initialize pandas sink config sink_config = PandasSinkConfig( dataframe=DataFrame() ) # initialize pandas sink sink = PandasSink()

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
