Supervised Learning for Document Classification with Scikit-Learn - QuantStart. Document Classification with scikit-learn. Document Classification with scikit-learn. Document classification is a fundamental machine learning task.
It is used for all kinds of applications, like filtering spam, routing support request to the right support rep, language detection, genre classification, sentiment analysis, and many more. To demonstrate text classification with scikit-learn, we're going to build a simple spam filter. While the filters in production for services like Gmail are vastly more sophisticated, the model we'll have by the end of this tutorial is effective, and surprisingly accurate. Spam filtering is kind of like the "Hello world" of document classification.
It's a binary classification problem: either spam, or not spam (a.k.a ham). We're going to use a combination of the Enron-Spam (in raw form) data sets and the SpamAssassin public corpus. Loading raw email data into a workable formatExtracting features from the raw data that an algorithm can learn fromTraining a classifierEvaluating accuracy by cross-validationImproving upon initial accuracy.
Sentiment Analysis with Python and scikit-learn – Marco Bonzanini. Sentiment Analysis is a field of study which analyses people’s opinions towards entities like products, typically expressed in written forms like on-line reviews.
In recent years, it’s been a hot topic in both academia and industry, also thanks to the massive popularity of social media which provide a constant source of textual data full of opinions to analyse. This article discusses one particular application of sentiment analysis: sentiment classification at the document level. In other words, given a document (e.g. a review), the task consists in finding out whether it provides a positive or a negative sentiment towards the product being discussed.
The following paragraphs describe the setup and the main components or our classification example with samples of code in Python using scikit-learn, a popular machine learning library. The complete code is discussed at the end of this post, and available as Gist on Github. Setting up for the experiments.

This lesson compares the SPARQL and SQL query languages, which are designed to query RDF and relational data, respectively.
You may be reading this lesson because you know one and want to learn the other or because you need to make some decisions about which to use for some purpose. First, let's look at their data models; that is, the way we consider their data to be structured. Comparing RDF and SQL data Many people ask what can be done with SPARQL that can't be done with SQL, when in fact they care about what can be done in RDF that can't be done with relational databases.
Both of these languages give the user access to create, combine, and consume structured data. Relational data is made up of rows of data collected into tables (also called a "relations" in formal relational literature).

Recent changes May 25, 2016. Dynos and the Dyno Manager. Last updated 23 August 2016 This article applies to the new dyno types on Heroku. If your application is still using the legacy dyno types, please refer to the Legacy Dynos article instead. The legacy dyno types offer different behavior than what is documented here. Dynos A dyno is a lightweight Linux container that runs a single user-specified command.
For information about dyno pricing, see the Heroku pricing overview. Terminology: Containerization is a virtualization technology that allows multiple isolated operating system containers to be run on a shared host. File Conversion API - Pricing. The Zamzar API was built with security in mind, all personal information and files are secure and protected. What is a conversion credit ? Every successful conversion costs at least 1 credit. Conversions that are more intensive to process can cost more - our formats page has all the details.
Are there any bandwith limits ? Yes - The first 50MB of any input file is included in your conversion cost. Api - How do I download a file or photo that was sent to my Telegram bot? Getting started with Telegram bots - unnikked. On 24 June Telegram released the new Bot platform. You can now create or use existing bots to enhance your Telegram experience. The new Bot platform is shipped with a fancy HTTP API mechanism, so building a custom Bot is a breeze. I was not able to wait more and after having played with my friends with the official bots I started to figure out how to use the APIs provided. Since the interaction is based purely on HTTP requests it was easy to me to get start easily using only my command line and some curl commands. BotFather The bot BotFather as the name suggests is the “father” of all bots (say again bot please), talking to this fancy program will let you create new children alongside an API token.
