Distributed video search

When you have a collection of data that is not distributed, that is all in one place, then it is fairly straightforward to query across the dataset. However when it is distributed you cannot possibly have an overview of the entire system. This is the problem of Web based information retrieval.

Multimedia resources compound the problem because they are continuous, and each resource may require special or custom processing in order to extract useful information. It is simply not possible to build a single query system that spans all types of video items; instead, you first need to build a layer which enables correlation of queries amongst different collections.

Annodex is such a layer.
