by Matt Teschke, Bernard Yuan

Novetta Machine Learning Center of Excellence effort to develop a deep learning model that predicts customer-relevant metadata tags for unstructured text.   BACKGROUND: ENRICHMENT OF UNSTRUCTURED TEXT DATA The rise of the internet has led to a faster flow of information, where news posted to a relatively obscure blog can be shared on social media and then reach national publications within hours. The volume is such that humans alone cannot filter out noise, identify important new information, and determine how messaging trends are changing over time. To address this challenge, Novetta Mission Analytics (NMA) helps customers analyze open source and...

Cyber Self-Defense: Five Ways to Protect Yourself

Category: Advanced Analytics / Big Data and Entity Analytics / Data Analytics / Novetta Nexus Tag(s):  /  /  /  /

by

  1. Be aware that you ARE a target. We hear it in Cyber Security circles pretty often; “I/we/my company doesn’t have anything Hackers want.” According to Verizon’s Data Breach Investigations Report (DBIR) for 2018, 76% of breaches were financially motivated. Attackers want your Personally Identifiable Information (PII) so they can assume your identity not only to steal your hard earned money from your bank accounts and Paypal account but also to apply for fraudulent credit cards. Cyber Criminals will even go as far as stealing a very young child’s identity to apply for credit and open up fraudulent accounts....

by

PHASE I RECAP We are exploring the problem space of Named Entity Recognition (NER): processing unannotated text and extracting people, locations, and organizations. A previous post described our comparative performance evaluation of several open source and commercial NER libraries. Based upon this evaluation we determined that Amazon Comprehend (an AWS solution) performed robustly against test corpora, while the top open source solutions for the NER task were AllenNLP ELMo, Stanford NER Tagger, and NeuroNER. PURPOSE This blog post picks up where the previous post left off, building on evaluation results to explore a practical application of NER. TOOLS To facilitate this...

Evaluating Solutions for Named Entity Recognition

Category: Advanced Analytics / Big Data and Entity Analytics / Data Analytics / Novetta Nexus Tag(s):  /  /  /  /

by

BACKGROUND Named Entity Recognition (NER) and Entity Extraction are interchangeable terms that refer to the task of classifying “named entities” into pre-defined categories such as the names of persons, organizations, locations, etc.1 Let’s look at an example of how this actually works. Given a sample input: John went to the Bank of America in Washington DC An NER algorithm will read in this sentence and look to tag words it recognized as persons, organizations, locations, etc. The following represents the tagged version of the sentence: [John]PERSON went to the [Bank of America]ORGANIZATION in [Washington DC]LOCATION Such tagging is useful because...

To gain insights into the state of the art of Named Entity Recognition (NER) solutions, Novetta conducted a quick-look study exploring the entity extraction performance of five open source solutions as well as AWS Comprehend.

Data Munging and Exploration

Getting to know your data and forming sound hypotheses This second post in the Predictive Analytics series will cover data munging and exploration. For the steps that come before the data, see the first post – Predictive Analytics for Intelligence. Here I’ll suggest tools and techniques to consider when acquiring and exploring the data relevant to your analytical questions. For the most part I’ll assume that you have access to the data, and that there are features within it that are “interesting” (and I’ll define what I mean by that along the way). Data Forms One of the main failings...

The Cyberwire Event Coverage – Novetta Tech Talk: Blockchain and Bitcoin Bitcoin enthusiasts aside (and there are a lot of them out there, including not just the stereotypical individual techno-libertarians and black marketeers, but some significant financial services companies as well) should people see the underlying blockchain technology as one with significance for their lives? Or is the blockchain nothing more than a flashy hashtag soon to be overtaken by other fads? Peder Müller, Novetta’s Deputy Director of Analytics, thinks the blockchain is significant. He made the case Monday at the Jailbreak Brewing Company in Laurel, Maryland, to Jailbreak’s usual...

Behavioral and Cognitive Biometrics 101

Category: Advanced Analytics / Novetta Nexus Tag(s):  /  /

by

The degree of interest in applications involving “cognitive fingerprints” has taken off in recent years, spearheaded in large part by government-sponsored research initiatives such as the Defense Advanced Research Projects Agency (DARPA) Active Authentication program, which has facilitated the exploration of numerous novel, multimodal behavioral and cognitive biometric authentication systems by both academic and private industry development teams. The practical interest in using these types of new biometrics is also fueled by the boom in wearable and mobile sensor technologies, which offer a growing number of mechanisms and platforms for continuously detecting, collecting and analyzing a rich array of user...

Novetta Entity Analytics Delivers Critical Requirements for Advanced 360 Entity Views. The ability to bring together data from multiple sources and produce complete views of entities for analysis can dramatically transform how organizations perform analytics. Analytics tools and applications with access to advanced 360-degree entity views benefit from richer and more contextual insights than ever before. Although the term “360-degree view” has been in use for years, most often it refers to a view of a subset of data about a person gathered from internal structured sources and presented in master data management (MDM) software or stored in a data...
