....rapid access to huge amounts of heterogeneous information in a distributed environment without any relocation, restructuring, or reformatting of data. Many researchers have investigated the use of metadata to support run time access to the original information [1,3,8,9,11, 12,13,19,26] Others [5,11,21,27] have investigated the use of data mining for the automatic extraction of metadata. We refine and synthesize some of the ideas contained in these efforts to provide advanced search and browsing capabilities without Bell Communications Research, 444 Hoes Lane, Piscataway, NJ 08854 LSDIS, ....

....making any assumptions about the location and representation of data. This is achieved by creating metadata and associating it with the original information. Metadata for different media types is often defined as derived properties of the media, which are useful in information access or retrieval [5]. It establishes rela tionships between information units (defined below) and portions of physical information that present logical units of interest for end users. An information unit (IU) is a metadata entity that encapsulates a logical unit of information. It represents the lowest level of ....

....for Kendra Metadata is basically the physical and conceptual details about data. The Web community has recognised the need for better metadata models for some time, while application and hierarchical storage system developers are only beginning to define the components and uses of such metadata [3, 6, 10]. We are defining a metadata reference model which encapsulates data description, location information, system information and current performance statistics. This project s contributions are generally applicable to global processing, yet our demonstration is specific to the entertainment industry ....

.... record that characterise an object [20] While there is a fair amount of extant research exploring uses of metadata, almost all of it concerns increasing searching effectiveness in information retrieval, and typically concentrates on the definition of particular models for a particular domain [10, 12, 24]. Over the past 30 years, metadata has been used to describe library information which is mainly text [10, 12] Today information scientists must extend their current metadata models to describe other data such as video and graphics [14, 18, 22, 26, 27] More recently, metadata model ....

....among the information. A data model is used to represent the extracted information and relationship among the information in a manner that can be used to process user queries and compose video. The concepts objects that characterize the information contained in video data are called metadata [17, 25, 36, 46]. Besides visual, audio transcripts can also be used as a source of metadata because considerable information exists in the audio stream. Based on visual and audio transcript metadata, we propose a novel four step hybrid approach for retrieval and composition of video newscasts. In the first step, ....

....transcripts. The text transcripts contain speaker information, so that the sequence of speakers in the audio is known. Speaker identification is used to identify points in the audio where the speaker changes. However, this does not provide word by word alignment. In the Mixed Media Access system [4], indexing and retrieval are performed across a variety of media. In particular, speaker indexing and keyword indexing are performed on the audio, while text segmentation is 1060 3425 98 10.00 (C) 1998 IEEE performed on associated text. Retrieval is based on queries across the media, however no ....

Speaker recognition gives very good results if samples of word of the different speakers are known (Orphe) [23 25]. The case of non supervised segmentation is still a subject of open research. Vocal dictation from continuous speaking gives good results if the vocabulary is limited and known (currently up to 64000 words) 26,27] as it is the case with scripts of videos. Techniques as word spotting also allow ....
