Aims and Objectives
This class will enable the student to understand the fundamentals of information access and information mining. The class will cover a range of techniques for extracting information from textual and non-textual resources, modelling the information content of resources, detecting patterns within information resources and making use of these patterns.
On completion of the class, a student should be able:
- to demonstrate a knowledge of the issues involved in representing information stored in electronic form, including text, images, video and speech
- to demonstrate a knowledge of the techniques for the access of information based on such representations
- to demonstrate a knowledge of the broad range of techniques for evaluating information access systems
- to demonstrate a knowledge of statistical approaches for detecting patterns within information
- to demonstrate a knowledge of the practical applications of large-scale information mining approaches
- to demonstrate an awareness of the current challenges of constructing large-scale information access systems
- to demonstrate practical competence in the range of issues associated with the class
Introduction, Information Access, the Web and Electronic Archives, including commercial and non-commercial applications.
Textual Information Storage & Retrieval: indexing, querying, ranking and retrieval. Document analysis and representation. Information Retrieval models (e.g. Boolean, Vector Space, Probabilistic, Fuzzy). Relevance feedback and clustering.
Textual Information Filtering: machine learning and information access. Content-based and collaborative-based filtering.
Image Retrieval: retrieval of images by semantic and visual features. Manual image indexing. Indexing by visual features (e.g. colour, texture, shape). Storage and retrieval.
Video Retrieval: video segmentation, representation, storage and retrieval. Document visualisation: presentation of multimedia retrieval results.
Evaluation of Information Access systems: user and system-oriented evaluation. TREC. User and task-oriented evaluation.
Web search engines: indexing and retrieval of multimedia information on the Web. Structured document indexing and retrieval. Analysis of link connectivity.
Information mining: detecting patterns within data. Techniques for information mining including clustering, classification, and association rule learning. Metrics for information mining.
