Automatic indexing of full texts

Information Processing & Management, 1984
Abstract The article deals with the preparation of query description using a semantic analyser method based on the analysis of semantic structure of documents. The aim of the paper is to demonstrate the efficiency of this method in the field of automatic indexing. The results obtained by means of this method are compared with the results of automatic

Automatically indexing documents

Proceedings of the 7th international conference on Intelligent user interfaces - IUI '02, 2002
Authors cite other work in many types of documents. Notable among these are research papers and web pages. Recently, several researchers have proposed using the text surrounding citations (references) as a means of automatically indexing documents for search engines, claiming that this technique is superior to indexing documents based on their content [

Automatic Video Database Indexing and Retrieval

Multimedia Tools and Applications, 1997
The increasing development of advanced multimedia applications requires new technologies for organizing and retrieving by content databases of still digital images or digital video sequences. To this aim image and image sequence contents must be described and adequately coded.

Experiments in automatic extracting and indexing

Information Storage and Retrieval, 1970
Abstract 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 ...

An Automatic Index Validity for Clustering

2010
Many validity index algorithms have been proposed to determine the number of clusters. These methods usually employ the Euclidean distance as the measurement. However, it is difficult for the Euclidean distance metric to evaluate the compactness of data when non-linear relationship exists between different components of data.

Indexing and automatic significance analysis

Journal of the American Society for Information Science, 1974
AbstractIntellectual indexing proceeds on three levels: The selection of phrases occurring in the document text (sequential indexing), the posting of specific phrases from the text to generic descriptors (generic indexing), and the choice of descriptors which are implicit to the document text (symbolic indexing).

Research and Application to Automatic Indexing

2010
Based on the study of TF-IDF, information gain and information entropy, the paper proposes an improved method of weight calculation, which combines the TF-IDF Normalization with information gain, to extract key words Moreover, to abstract indexing words with counting semantic similarity of the key words in order to finish a process of automatic ...

Automatic Indexing in a Drug Information Portal

2009
Objective: The objective of this work is to create a bilingual (French/English) Drug Information Portal (DIP), in a multi-terminological context and to emphasize its exploitation by an ATC automatic indexing allowing having more pertinent information about substances, organs or systems on which drugs act and their therapeutic and chemical ...

PROBABILISTIC AUTOMATIC INDEXING BY LEARNING FROM HUMAN INDEXERS

Journal of Documentation, 1984
A 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, 1996
Efficient 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.
