Managing product descriptions with Oracle Enterprise Data Quality Many organisations purchase the same products from multiple suppliers and commonly ask the suppliers to provide data as to the manufacturer, description, part number etc. Unfortunately each supplier usually has their own format for the data they supply and no way to convert the content into a format specified or required by the buyer. Oracle Enterprise Data Quality provides a range of tools and techniques for...

While exploring natural language processing (NLP) and various ways to classify text data, I wanted a way to test multiple classification algorithms and chains of data processing, and perform hyperparameter tuning on them, all at the same time. I ended up using Apache Spark with the CrossValidator and pipeline models. This article will detail the approach. Import statements. Nothing will be detailed here. These are just provided to make running this yourself simple. from...

Introduction This post will compare vectorizing word data using term frequency-inverse document frequency (TF-IDF) in several python implementations. TF-IDF is used in the natural language processing (NLP) area of artificial intelligence to determine the importance of words in a document and collection of documents, A.K.A. corpus. Various implementations of TF-IDF were tested in python to gauge how they would perform against a large set of data. Tested were sklearn, gensim...

Introduction In the course of prepping some data for a machine learning activity using natural language processing (NLP), several methods were used to compare the performance and volume of data that could be efficiently processed. This post will show the performance of cleaning a small set, and a larger set of data. All examples are in python, and compare the use of Pandas dataframes, Dask dataframes, and Apache Spark (pyspark). Test environments The small dataset was...

Last Validation: August 31, 2020 for OAC 105.7 Introduction This post details the steps required to connect Oracle Analytics Cloud (OAC) to a private Essbase 19c Marketplace instance in Oracle Cloud Infrastructure (OCI) using a public load balancer. Both Data Visualization (DV) and RPD connections are described. This method bypasses the need for Remote Data Gateway (RDG) or Remote Data Connector (RDC). Note: This is an exception to the rule that OAC connections to private...
