Talking to the Semantic Web
Talking to the Semantic Web: Query Interfaces to Ontologies for the Rest of Us
The Semantic Web presents the vision of a distributed, dynamically growing knowledge base founded on formal logic. Common users, however, seem to have problems even with logic and formal query languages. So how can we help users to query a web of logic that they do not seem to understand?
An often proposed solution to address this problem is the use of natural language for knowledge specification and querying. The development of Natural Language Processing (NLP) tools, however, requires computationally intensive algorithms relying on large amounts of background knowledge making the tools highly domain-dependent and virtually inapplicable to new domains or applications.
To that end we have implemented five natural language interfaces:
- Querix (Please read an important note about the name here)
- Semantic Crystal
Ginseng and SWAT allow users to formulate queries in a restricted, controlled query language akin to full English. We have shown that these kinds of interfaces are simple to use and provide superior retrieval performance to traditional logic-based approaches when used by a casual user.
We also developed two domain-independent full natural language interfaces: Querix and NLP-Reduce. Both approaches are simple and do not use any complex semantic-based technologies. They are, therefore, completely portable and domain-independent.
Additionally, we designed Semantic Crystal - an interface that features a graphically displayed, clickable formal query language. The main advantages for users are that they can view the graphically displayed knowledge base they are querying and assemble queries by clicking on the elements in the graph.
