fastText
Library for fast text classification and representation
FastText is an open-source, free, lightweight library that allows users to learn text representations and text classifiers. It works on standard, generic hardware. Models can later be reduced in size to even fit on mobile devices. ext classification is a core problem to many applications, like spam detection, sentiment analysis or smart replies. In this tutorial, we describe how to build a text classifier with the fastText tool. The goal of text classification is to assign documents (such as emails, posts, text messages, product reviews, etc...) to one or multiple categories. Such categories can be review scores, spam v.s. non-spam, or the language in which the document was typed. Nowadays, the dominant approach to build such classifiers is machine learning, that is learning classification rules from examples. In order to build such classifiers, we need labeled data, which consists of documents and their corresponding categories (or tags, or labels). -

Guide to Open Source Sentiment Analysis Software
Open-source sentiment analysis software is a type ofprogram that is designed to examine and interpret the meaning of natural language (human) text. This type of software is used to analyze public opinion about specific topics or products, by identifying patterns in text and extracting meaningful insights. By analyzing text data from social media platforms such as Twitter, blogs, and news articles, sentiment analysis software can gauge how people feel about particular topics.
Sentiment analysis software uses Natural Language Processing (NLP) techniques to read and analyze text data. First, it breaks down the text into its component parts - such as words and phrases - then it identifies parts-of-speech and calculates the sentiment score for each word or phrase. The sentiment score measures how positive or negative a given piece of text is on a scale from -1 (very negative) to +1 (very positive). Once all the scores are calculated, they are combined together and interpreted by humans in order to identify overall trends in opinion about given topics or products.
There are several different open source sentiment analysis programs available today which allow users to create their own analytics tools without licensing fees or proprietary restrictions imposed by commercial solutions. These programs have many advantages compared with commercial programs, including cost savings due to lower licensing fees, greater flexibility in customization for specific applications, ability to access the source code for troubleshooting purposes and ample support from fellow users through online forums provided by developer communities like Github. Also since these tools are open source they can be constantly updated with new features without having to purchase additional licenses or incur upgrade fees associated with commercial packages. Open source sentiment analysis programs also provide opportunities for developers who wish to contribute their own extensions back into the community after they have tested them on their own datasets successfully.
In summary, open source sentiment analysis software provides an excellent opportunity for people interested building advanced analytics systems at low cost while gaining access a supportive development community willing help along every step of way make sure things run smoothly free proprietary restrictions and excessive licensing costs associated with competitors’ solutions.
