In this working session, we will discuss methods which could plausibly be used for combining evidence for assigning semantic tags to words in a text. We will discuss methods that apply at knowledge acquisition time to produce a single static knowledge source to be used by a single, complete, semantic tagger, as well as methods for dynamically combining outputs of a set of independent, possibly ...

A variety of knowledge sources have been employed by error correction mechanisms to improve the usability of speech recognition (SR) technology. However, little is known about the effect of knowledge sources on human error correction. Advancing our understanding of the role of knowledge sources in human error correction could improve the state of automatic error correction. We selected three kn...

We describe how the architecture of the modularized linlin dialogue manager can be augmented to handle the cases where the user's initial information request is underspeci ed, and where therefore the system needs to ask the user about the missing pieces of information. In many existing spoken dialogue systems this has been handled by a so-called task model, which has been embedded in the dialog...

The ubiquitous non-semantic web includes a vast array of unstructured information such as HTML documents. The semantic web provides more structured knowledge such as hand-built ontologies and semantically aware databases. To leverage the full power of both the semantic and non-semantic portions of the web, software systems need to be able to reason over both kinds of information. Systems that u...

Biomedical data integration currently exists as a “loose federation of bio-nations.” (Goble 2008) While work is being done to integrate data sources it often involves “‘semantic creep’ – timid, piecemeal and ad hoc adoption of parts of standards.” (Good 2006) Linking data across resources is necessary for building integrated systems (e.g. Belleau 2008, Ruttenberg 2009); however, linking the dat...

As scientists work to understand the complex interactions in the Earth's atmosphere, oceans, biosphere, surface, and interior, they increasingly find themselves working with a more diverse set of data, complex science algorithms, and models. However, each new dataset, algorithm, or model requires its own knowledge base to obtain reliable and useful results. Acquiring this knowledge base can be ...

In this paper we investigate the application of Galois (or concept) lattices on different information or data sources (e.g. web documents or bibliographical items) in order to organise knowledge that can be extracted from the data. This knowledge organisation can then be used for a number of purposes, e.g. knowledge management in an organisation, document retrieval on the Web, etc. Galois latti...

Domain-specific repositories of manually created semantic descriptors usually contain detailed knowledge with “heavy-weight” semantics about particular aspects of the domain, but they often lack common knowledge about the concepts and entities that are described. Integrating some of this common knowledge into the repository can enhance the capabilities of semantic search in the repository. We u...
