The Reason That Search Engines Are Fast But Not Very Accurate

Search Engine Efficiency has been an active field of Information Retrieval research for many years and the literature is vast. When implementing a search engine it is necessary to wade through this literature and to make engineering decisions on what to implement and what to not. Andrew has recently implemented an new efficient search engine and in this presentation will outline its design. This search engine is fast and accurate, but as he will show; academically accurate. Unfortunately, it's not quite so obvious what academic accuracy means for a user.

Multimedia and Information Systems
Our research is centred around the theme of Multimedia Information Retrieval, ie, Video Search Engines, Image Databases, Spoken Document Retrieval, Music Retrieval, Query Languages and Query Mediation.

We focus on content-based information retrieval over a wide range of data spanning form unstructured text and unlabelled images over spoken documents and music to videos. This encompasses the modelling of human perception of relevance and similarity, the learning from user actions and the up-to-date presentation of information. Currently we are building a research version of an integrated multimedia information retrieval system MIR to be used as a research prototype. We aim for a system that understands the user's information need and successfully links it to the appropriate information sources, be it a report or a TV news clip. This work is guided by the vision that an automated knowledge extraction system ultimately empowers people making efficient use of information sources without the burden of filing data into specialised databases.
