Knowledge Technologies for Information Acquisition and Retrieval

Compendium of the project:

The project is focused on using knowledge modelling methods for solving information acquisition and information retrieval tasks. It is based on creating domain models in the form of conceptual models of different application areas. Elements of these models enable to represent a context of textual and non-textual documents explicitly. Within this framework the focus of the project activities is on:
  • Building of domain models
  • Manual and automatic annotation of documents based on a particular domain model
  • Indexing of knowledge stored in databases
  • Retrieval of relevant documents and/or relevant parts of these documents
  • Categorisation and clustering of textual documents
  • Automatic generation of document abstracts

Key words:

Knowledge modelling, ontology, information search and retrieval, document annotation, classification and clustering of documents

Annotation of project resuls:

A way how to use ontological domain models to organise documents in text collections was proposed. The method is based on enriching documents by links to relevant parts of a model. A functional architecture of a communication forum employing an ontological model was designed.

Text mining methods were used for the creation of ontological models. A preliminary version of an ontological model is formed by clustering of available documents. Annotation of a document against an ontology is supported by classification of the processed document.

In the field of document retrieval, approaches based on ontological models, Latent Semantic Indexing, and using the WordNet semantic database were investigated. A method for 'soft' retrieval employing the structure of an ontological model was proposed.

A way how to decrease the cognitive load of a user while searching the WWW space was proposed. The method suggests WWW pages relevant from the point of users' interests. It is based on the automatic creation of user model from logs of WWW servers.
