Combining Concept-with Content-Based Multimedia Retrieval

Item Modeling Concept Based on Multimedia Authoring

In this paper a modern item design framework for computer based assessment based on Flash authoring environment will be introduced. Question design will be discussed as well as the multimedia authoring environment used for item modeling emphasized. Item type templates are a structured means of collecting and storing item information that can be used to improve the efficiency and security of the...

Combining Term-based and Concept-based Representation for Clinical Retrieval

Biomedical domain retrieval has been a trending topic that attracts many IR researchers. Different document representation methods, i.e., term based representation and concept based representation, have been proposed to solve this question. However, previous studies have focused the verbose queries. In this year’s Precision Medicine track, we evaluated the performance of these two basic documen...

Representation Issues in Multimedia Case Retrieval

Video stories are an effective way to teach complex subjects, but video is opaque to a computer program. To what extent must the content of such stories be represented? We present three issues in story indexing that affect the distinctions that must be drawn in story representation and illustrate these issues with examples from ORCA, a pedagogical case-retrieval system in the domain of organiza...

Support concept-based multimedia information retrieval: a knowledge management approach

Identified as an important management concept five years ago (Gamer 1999), knowledge management (KM) aims to enable organizations to capture, organize, and access their intellectual assets. This paper proposes a prototype system that applies a knowledge management approach to support concept-based multimedia information retrieval by integrating various information analysis and image processing ...
