Broadcast news navigation using story segmentation

Abstract: In this paper we examine tire developed techniques and lessons learned in an operational multimedia exploitation system, Broadcast News Editor (BNE) and Broadcast News Navigator (BNN). BNE captures, analyzes, annotates, segments, summarizes, and stores broadcast news audio, video and textual data within tlte context of multimedia database system BNN provides web based retrieval tools from the multimedia database system. TJle key innovation of this system is the detection and segmentation of story segments from the multimedia broadcast stream. TJtis paper discusses: . TJte utility of using story segments to discover broadcast news stories of interest . Tlte textual, video, and audio cues used for story segment detection . Teclmiques developed for identifying story segments . Details of tlte operational BNE and BNN system BNE and BNN are currently used every evening at MJTRE’s Multimedia Researclz Lab and to this point have automatically processed over 6011 news stories from over 349 broadcasts of CNN Prime News ‘t?

TCP extensions for space communications

Abstract: The space communication environment and mobile and wireless communication environments show many similarities when observed from the perspective of a transport protocol. Both types of environments exhibit loss caused by data corruption and link outage, in addition to congestion‐related loss. The constraints imposed by the two environments are also similar – power, weight, and physical volume of equipment are scarce resources. Finally, it is not uncommon for communication channel data rates to be severely limited and highly asymmetric. We are working on solutions to these types of problems for space communication environments, and we believe that these solutions may be applicable to the mobile and wireless community. As part of our work, we have defined and implemented the Space Communications Protocol Standards‐Transport Protocol (SCPS‐TP), a set of extensions to TCP that address the problems that we have identified. The results of our performance tests, both in the laboratory and on actual satellites, indicate that the SCPS‐TP extensions yield significant improvements in throughput over unmodified TCP on error‐prone links. Additionally, the SCPS modifications significantly improve performance over links with highly asymmetric data rates.

Stereoscopic display using rapid varifocal mirror oscillations.

Abstract: A dynamic volumetric display technique is described in which a vibrating membrane mirror is used in conjunction with an appropriate two-dimensional pattern generator. The mirror can be driven electrostatically or by a loudspeaker and causes the virtual image of the pattern surface to sweep out a volume of image space. The two-dimensional pattern is a repetitively time-varying one and can be generated by stroboscopic optical projection, by a computer, or other means. The volumetric figures which were generated include a simulated air traffic control situation display and a mathematical surface.

MITRE: description of the Alembic system used for MUC-6

Abstract: As with several other veteran MUC participants, MITRE's Alembic system has undergone a major transformation in the past two years. The genesis of this transformation occurred during a dinner conversation at the last MUC conference, MUC-5. At that time, several of us reluctantly admitted that our major impediment towards improved performance was reliance on then-standard linguistic models of syntax. We knew we would need an alternative to traditional linguistic grammars, even to the somewhat non-traditional categorial pseudo-parser we had in place at the time. The problem was, which alternative?
