GATE
LGPL licence.
GATE is used to perform tasks where meaningful text content needs to be detected and encoded in a structured form by adding annotations to text segments. GATE is used along with NLTK, R and RapidMiner.
The system is used for information extraction, manual and automatic semantic annotation, coreferentiality analysis, operations with ontologies (e.g. WordNet), machine learning (Weka, RASP, MAXENT, SVM Light), blog post flow analysis.
Clients: Twitter.

Use cases
Some recent projects we worked on:
- COMRADES:
Collective Platform for Community Resilience and Social Innovation during Crises.
- KNOWMAK:

Benefits
The GATE architecture consists of interconnected components: “pieces” of software with clearly defined interfaces that can be deployed in different contexts.
GATE implements out-of-the-box solutions for tokenization, tagging, text-to-speech splitting (splitter), named entity extraction, and machine learning.
The components are divided into three categories by their functions:
Language Resources (LR), Processing Resources (PR) – document processing programs (resources), Visual Resources (VR).
