Lingmotif

Sentiment Analysis made easy

Background

Lingmotif is the result of Research Project FFI2011-25893, which was carried out during the years 2012-2015, and will be continued over the years 2017-2019 with Project FFI2016-78141-P on Sentiment Analysis, both funded by the Spanish Ministry of Science and Innovation, developed by the Tecnolengua Group at the University of Málaga.

We aim to obtain high-coverage, high-quality lexical resources for Sentiment Analysis.

Description

Lingmotif is a multi-platform desktop application that analyzes input texts from a Sentiment Analysis perspective. Basically, it determines the semantic orientation of a text (whether it is positive or negative, and to what extent), by detecting linguistic expressions of polarity, i.e., positivity or negativity.

Unlike most Sentiment Analysis software, Lingmotif is not “just” a classifier, meaning it doesn’t simply classify an input text as positive or negative, it also offers a rich set of quantitative data, a visualization of the “sentiment profile” of the text(s) (including time series), and a detailed qualitative analysis showing text items that were detected as having some kind of semantic orientation. Lingmotif generates HTML files as output, so they can be viewed and searched using any standard browser.

These features make Lingmotif quite unique, and make it useful for a wide range of applications.

Currently, Lingmotif is able to analyze English and Spanish texts. We are working on French, German, and Italian.

The Windows installer allows you to install Lingmotif as “portable”. In this mode, no system files are modified, and no uninstallation is necessary. This is convenient for computer labs and other setups where regular users are not allowed to install new software. The regular installation will create a “Tecnolengua Lingmotif” entry in the Windows registry.

Linux

Uncompress the tar.gz file. Place the Lingmotif folder on a (writable) location of your choice. Run the “Lingmotif” binary file either by double-clicking on it from your file manager or by typing “./Lingmotif” from a terminal.

Lingmotif has only been tested on Ubuntu 16.04. It may or may not work on other Linux versions.

All Versions

When Lingmotif is started for the first time, a window will pop up asking you to provide an output folder. You need to have write permissions on this folder. If you fail to provide a suitable folder, Lingmotif will not run correctly.

On a regular setup, simply accept the suggested default folder. You can change this location later from the File – Select Output Folder menu.
