Sentiment Analysis In Action
Sentiment analysis is the automated analysis of content like text or speech as positive, neutral or negative. That positive or negative analysis can be considered looking at the polarity of the words and a result of sentiment analysis is often a polarity score. This type of scoring allows organizations to better understand how constituents see them. This might mean analyzing Twitter or Facebook, tagging a sentiment score on blog posts or comments on posts.
Using technology like sentiment analysis we get insight into how clients and employees see products, the company, support cases, or services. This is usually done using natural language processing part of a body of work we tend to generically call machine learning. Sentiment analysis has become key for many industries to figure out what people think and to then improve the experience with products and address any branding concerns or promote positive branding when possible.
While natural language techniques in...

New Perspectives On The Three Horizons Model
For a long time, the McKinsey Three Horizons model has been a systematic approach to look at the strategy of innovation in larger companies. It laid out three horizons, or time lines, that innovation comes in. Many enterprises have used the model to stay competitive in emerging markets. But we do so with a lower impact today than we used to. Even though incumbents in markets continue to grow quickly. Until we stop.
Defining The Three Horizons Model
The model came out in 2000, the same year the dot com bubble burst. Think about this: when Baghai, Coley, and White wrote The Alchemy of Growth, it was a disruptive model. And selling a good or service online was actually considered innovative. Like Pets.com.
The goal was to execute business models while researching and building new capabilities. And many of those took years to develop. Today, we can probably launch a new product in months if not weeks. That might be...

AA20-031A: Detecting Citrix CVE-2019-19781
Original release date: January 31, 2020
Summary
Unknown cyber network exploitation (CNE) actors have successfully compromised numerous organizations that employed vulnerable Citrix devices through a critical vulnerability known as CVE-2019-19781.[1]
Though mitigations were released on the same day Citrix announced CVE-2019-19781, organizations that did not appropriately apply the mitigations were likely to be targeted once exploit code began circulating on the internet a few weeks later.
Compromised systems cannot be remediated by applying software patches that were released to fix the vulnerability. Once CNE actors establish a foothold on an affected device, their presence remains even though the original attack vector has been closed.
The Cybersecurity and Infrastructure Security Agency (CISA) is releasing this Alert to provide tools and...

Generic Machine Learning Recommender Script
Been working more on building really generic and simple machine learning tools. This one is a generic recommendation script built to run as a lambda or gcf. This iteration on my GitHub is built to run locally but it’s straight forward enough to import json, parse, and run it as a microservice.
Requirements
- numpy
- gensim
- nltk==3.4.5
- textblob==0.15.3
Usage
Run locally, the recommender crawls through a column of a csv and matches the recommendations for similar content.
Those are based on the content passed in the –text field. Can use the –recs option to define the number of recs you’d like to recieve in response.
python recommender.py --file='my.csv' --text="Flash update" --column="title" --recs=...
