Natural Language Processing is the task we give computers to read and understand (process) written text (natural language). By far, the most popular toolkit or API to do natural language processing is the Natural Language Toolkit for the Python programming language. The NLTK module comes packed full of everything from trained algorithms to identify parts of speech to unsupervised machine learning algorithms to help you train your own machine to understand a specific bit of text. NLTK also comes with a large corpora of data sets containing things like chat logs, movie reviews, journals, and much more! Bottom line, if you're going to be doing natural language processing, you should definitely look into NLTK!

You take a look at the data and quickly realize it's an absolute mess. According to IBM Data Analytics you can expect to spend up to 80% of your time on a project cleaning data. There's all different types of messy data, but today we're going to focus on one of the most common, missing values. We'll take a look at standard types that Pandas recognizes out of the box. Next we'll take a look at some non-standard types. These are inputs that Pandas won't automatically recognize as missing values. After that we'll take a look at unexpected types. Let's say you have a column of names that contains a 12, technically that's a missing value. After we've finished detecting missing values we'll learn how to summarize and do simple replacements.

Welcome to a Python for Finance tutorial series. In this series, we're going to run through the basics of importing financial (stock) data into Python using the Pandas framework. From here, we'll manipulate the data and attempt to come up with some sort of system for investing in companies, apply some machine learning, even some deep learning, and then learn how to back-test a strategy. I assume you know the fundamentals of Python. If you're not sure if that's you, click the fundamentals link, look at some of the topics in the series, and make a judgement call. If at any point you are stuck in this series or confused on a topic or concept, feel free to ask for help and I will do my best to help. https://pythonprogramming.net https://twitter.com/sentdex https://www.facebook.com/pythonprogramming.net/ https://plus.google.com/+sentdex

Pandas is a Python module, and Python is the programming language that we're going to use. The Pandas module is a high performance, highly efficient, and high level data analysis library. At its core, it is very much like operating a headless version of a spreadsheet, like Excel. Most of the datasets you work with will be what are called dataframes. You may be familiar with this term already, it is used across other languages, but, if not, a dataframe is most often just like a spreadsheet. Columns and rows, that's all there is to it! From here, we can utilize Pandas to perform operations on our data sets at lightning speeds. Sample code: http://pythonprogramming.net/data-analysis-python-pandas-tutorial-introduction/ Pip install tutorial: http://pythonprogramming.net/using-pip-install-for-python-modules/ Matplotlib series starts here: http://pythonprogramming.net/matplotlib-intro-tutorial/

One of the most common challenges in business today is extracting data from formatted reports so that the underlying data can be analyzed in a flexible way. The default solution to this problem is re-keying printed reports into spreadsheets. That is a very time-consuming and error-prone method, especially if it has to be repeated on a monthly, weekly or even daily basis. Let’s take a look at a better way… Datawatch makes the data acquisition process simple and easy through a drag-and-drop interface that intelligently parses PDF reports and other desktop files, and extracts the data it finds into a flat table of rows and columns. Occasionally the automatic parser needs some human guidance to ensure it is interpreting the report data correctly. These fine-tuning operations are also presented in an intuitive way. This table can then be sent to downstream applications and business processes, or further prepared and joined with other data to get a complete view of the information. But it doesn’t end here. With Datawatch, to ACQUIRE data means reaching and loading data where ever it is, in whatever format it is. In addition to loading semi-structured and multi-structured data, Datawatch offers out-of-the-box connectivity to a large number of structured data sources. Your data can be stored locally or online, in a file or in a database, it can be historic data-at-rest or streaming data generated in the moment – Datawatch lets you use it all.

In this video, we'll learn about K-fold cross-validation and how it can be used for selecting optimal tuning parameters, choosing between models, and selecting features. We'll compare cross-validation with the train/test split procedure, and we'll also discuss some variations of cross-validation that can result in more accurate estimates of model performance.

Evaluating Text Extraction: Apache Tika's™ New Tika-Eval Module - Tim Allison, The MITRE Corporation Text extraction tools are essential for obtaining the textual content and metadata of computer files for use in a wide variety of applications, including search and natural language processing tools. Techniques and tools for evaluating text extraction tools are missing from academia and industry. Apache Tika™ detects file types and extracts metadata and text from many file types. Tika is a crucial component in a wide variety of tools, including Solr™, Nutch™, Alfresco, Elasticsearch and Sleuth Kit®/Autopsy®. In this talk, we will give an overview of the new tika-eval module that allows developers to evaluate Tika and other content extraction systems. This talk will end with a brief discussion of the results of taking this evaluation methodology public and evaluating Tika on large batches of public domain documents on a public vm over the last two years. About Tim Allison Tim has been working in natural language processing since 2002. In recent years, his focus has shifted to advanced search and content/metadata extraction. Tim is committer and PMC member on Apache PDFBox (since September 2016), and on Apache POI and Apache Tika since (July, 2013). Tim holds a Ph.D. in Classical Studies from the University of Michigan, and in a former life, he was a professor of Latin and Greek.
