Semantic Assets: Latent Structures for Knowledge Management

In standard information retrieval systems, queries can be specified with differ- ent languages (string patterns, logical formulas, and so on). It is well known that it is hard to simultaneously maximize quality measures for query answers, such as, e.g., precision and recall.

Retrieval of documents with high recall, while maintaining at least a decent precision level, is a frequent problem in knowledge management (KM) contexts based on information retrieval (IR) processes, e.g., for information association in business contexts. Similar to making implicit knowledge explicit, deriving explicit symbolic content descriptions is important in KM tasks.

In this thesis we show how explicit symbolic descriptions can be combined with implicit holistic content representations known from information retrieval in order to support knowledge management processes in general, and informa- tion association based on IR query answering in particular. The methodology exhibited in this thesis is verified using representative examples, and validated with feasibility and effectiveness studies.
