The User Preference Model in Emergency Knowledge Representation

Abstract:

By analyzing influence factors of the document that the retrieval system recommends to the user, a user preference model is established. Based on the correlation between the emergency vocabularies, which is adjusted by the user preference model, a vocabulary correlation matrix is put forward to extend the retrieval model. Furthermore, according to new retrieval results and records of user operation, the user preference model is optimized. Finally, the validity and usefulness of the keyword extension-based user preference model in the algorithm is verified.
