Entities (such as people, organizations, or products) are meaningful units for organizing information and can provide direct answers to many search queries. Nordlys is a toolkit for entity-oriented and semantic search.
Nordlys currently supports four entity-oriented tasks, which are core components in semantic search:
- Entity cataloging
- Entity retrieval
- Entity linking in queries
- Target type identification
- General-purpose information retrieval and machine learning components at its core
- Implementations of various methods for the above entity-oriented search tasks (with more on their way)
- Based on the DBpedia knowledge base (extendible to other knowledge bases)
- Can used as a black box through a RESTful API
- Can be reached via a graphical web user interface
- Can be deployed on a local server and used as a Python package or as a command line tool
- Highly modular and well documented code, based on a 3-tier architecture
- Open source project that is actively being developed
Nordlys is not (yet) a mature production-level system, but rather a research prototype (as can be seen from the current version number, which is v0.2). We welcome contributions on all levels (pull requests, suggestions for improvements, feature requests, etc.).
