Information Graphic Classification, Decomposition and Alternative Representation
Direct linkDirect link
Gao, Jinglun – ProQuest LLC, 2012
This thesis work is mainly focused on two problems related to improving accessibility of information graphics for visually impaired users. The first problem is automated analysis of information graphics for information extraction and the second problem is multi-modal representations for accessibility. Information graphics are graphical…

Performance of Visual, Verbal, and Combined Video Surrogates.
Ding, Wei; Soergel, Dagobert; Marchionini, Gary – Proceedings of the ASIS Annual Meeting, 1999
Investigates the information representation power of different modalities in the video data in order to collect empirical evidence for video surrogate creation and thus better support effective video browsing and information retrieval. Three types of video surrogates were created and compared under two user tasks--verbal comprehension and visual…

Exploiting Multimodal Context in Image Retrieval.
Peer reviewed Peer reviewed
Srihari, Rohini K.; Zhang, Zhongfei – Library Trends, 1999
Finding information on the Web without encountering numerous false positives poses a challenge to multimedia information retrieval systems (MMIR). This research focuses on improving precision and recall in an MMIR system by interactively combining text processing with image processing in both the indexing and retrieval phases. A picture search…

The N-Gram Hypothesis Applied to Matched Sets of Visualized Japanese-English Technical Documents.
Rorvig, Mark; Smith, Michael M.; Uemura, Aya – Proceedings of the ASIS Annual Meeting, 1999
Shape Recovery Analysis (SHERA), a new visual analytical technique, is applied to the N-Gram hypothesis on matched Japanese-English technical documents. Results reveal compaction in the translation of Japanese subject terms to English subject terms. The biagram approach to the Japanese data yields a remarkable similarity to the matching visualized…

The Identification of Index Terms in Natural Language Object Descriptions.
Heidorn, P. Bryan – Proceedings of the ASIS Annual Meeting, 1999
Examines the vocabulary and communication constructs that are used by novices and domain experts to describe objects in an object identification task. Results suggest that indexing and retrieval systems should provide semantic level similarity mechanisms to allow for whole-object as well as part-wise visual analogy. The systems should also provide…

Automatic Caption Localization for Photographs on World Wide Web Pages.
Peer reviewed Peer reviewed
Rowe, Neil C.; Frew, Brian – Information Processing & Management, 1998
Explores the indirect method of locating for indexing the likely explicit and implicit captions of photographs, using multimodal clues including the specific words used, syntax, surrounding layout of the Web page, and general appearance of the associated image. The MARIE-3 system thus avoids full image processing and full natural-language…
