There is a trend towards construction of multimedia digital information resources which may hold diverse data types in the form of image, graphics, audio, video, and text based retrieval artifacts or objects. WWW is a huge multimedia information resource. Existing search mechanisms available on WWW are mostly mono-modal. Multimedia information needs are partially satisfied by using mono-modal search...
Information retrieval systems that search within multimedia artifacts face inter-modality fusion problem. Fuzzy logic, sequential and linear combinational techniques are used for inter-modality fusion. We explore asymptotically that Fuzzy logic and sequential techniques have limitations. One major limitation is that they only address fusion of documents coming from different modalities, not document...
Task Analysis techniques models the human activity for the computer based systems. The role of task analysis is vital in the interface design. In recent years, various task analysis techniques have been explored by the researchers, which include Hierarchical Task Analysis (HTA), Cognitive Task Analysis (CTA), Link Analysis (LA), and Timeline Analysis (TA). We have explored that task analysis techniques...
