Experiments in automatic extracting and indexing
Information Storage and Retrieval, 1970Abstract This article reports on several experiments in automatic extracting and on one experiment in automatic indexing. Nine chapters, each from a different technical book, were used as the text corpus for all the experiments. In the first experiment, an attempt was made to construct a sentence dictionary of syntactic sentence types, for ...

PROBABILISTIC AUTOMATIC INDEXING BY LEARNING FROM HUMAN INDEXERS
Journal of Documentation, 1984A probabilistic model previously used in relevance feedback is adapted for use in automatic indexing of documents (in the sense of imitating human indexers). The model fits with previous work in this area (the ‘adhesion coefficient’ method), in effect merely suggesting a different way of arriving at the adhesion coefficients.

Automatic text recognition for video indexing
Proceedings of the fourth ACM international conference on Multimedia - MULTIMEDIA '96, 1996Efficient indexing and retrieval of digital video is an important aspect of video databases. One powerful index for retrieval is the text appearing in them. It enables content- based browsing. We present our methods for automatic segmentation and recognition of text in digital videos.

A Survey on the Automatic Indexing of Video Data,
Journal of Visual Communication and Image Representation, 1999Today a considerable amount of video data in multimedia databases requires sophisticated indices for its effective use. Manual indexing is the most effective method to do this, but it is also the slowest and the most expensive. Automated methods have then to be developed.

An experiment in automatic indexing
American Documentation, 1965AbstractThis report describes a method of indexing documents which is based on the assumptions, (1) that a subset of the words in a document can be an effective index to that document and, (2) that this subject can be approximated by selecting those words from the document whose frequencies are statistically unexpectedly high.
