added silent argument in initsentiment.ai
using method = “auto” in init_sentiment.ai() now uses py_discover_config
Patch for case when no conda binary is present
updated default python to 3.8.10 for virtualenv and conda compatibility
get_default_embedding had a typo
in the initial launch and was called get_defualt_embedding.
Make sure to update your code if you used this function.INITIAL RELEASE see github page for details
Korn Ferry
Institute’s AITMI team made sentiment.ai for
researchers and tinkerers who want a straight-forward way to use
powerful, open source deep learning models to improve their sentiment
analyses. Our approach is relatively simple and out performs the current
best offerings on CRAN and even Microsoft’s Azure Cognitive Services.
Given that we felt the current norm for sentiment analysis isn’t quite
good enough, we decided to open-source our simplified interface to turn
Universal Sentence Encoder embedding vectors into sentiment scores.
We’ve wrapped a lot of the underlying hassle up to make the process as simple as possible. In addition to just being cool, this approach solves several problems with traditional sentiment analysis, namely:
More robust, can handle spelling mitsakes and mixed case, and can be applied to dieciséis (16) languages!
Doesn’t need a ridged lexicon, rather it matches to an embedding vector (reduces language to a vector of numbers that capture the information, kind of like a PCA). This means you can get scores for words that are not in the lexicon but are similar to existing words!
Choose the context for what negative and
positive mean using the sentiment_match() function. For
example, you could set positive to mean
"high quality" and negative to mean
"low quality" when looking at product reviews.
Power Because it draws from language embedding models trained on billions of texts, news articles, and wikipedia entries, it is able to detect things such as “I learned so much on my trip to Hiroshima museum last year!” is associated with something positive and that “What happeded to the people of Hiroshima in 1945” is associated with something negative.
The power is yours We’ve designed
sentiment.ai such that the community can contribute
sentiment models via github.
This way, it’s easier for the community to work together to make
sentiment analysis more reliable! Currently only xgboost and glms
(trained on the 512-D embeddings generated with tensorflow) are
supported, however in a future update we will add functionality to allow
arbitrary sentiment scoring models.
