The Fully Automatic Syntactically‐based Indexing of Text (FASIT) system represents the contents of a document without a full parse or semantic analysis of the text. Content‐bearing units are isolated and then grouped into quasi‐synonymous classes whose main term is used to index the document.

A blueprint for automatic indexing
ACM SIGIR Forum, 1981This note summarizes some of the currently available insights in automatic indexing. The emphasis is on aspects that are expected to be useful in practical automatic indexing applications. The discussion is necessarily cursory, but the references will lead interested readers to a deeper treatment of the indexing problem.

Automatic versus manual indexing
Information Processing & Management, 1977Abstract A comparative evaluation has been carried out on the Philips “DIRECT” and the British “INSPEC” retrieval system. DIRECT is based on automatic indexing whereas INSPEC uses manual subject indexing. Two queries were submitted to both systems, using the same data base. The results are expressed in terms of recall and precision.

This article reviews the state of the art in automatic indexing, that is, automatic techniques for analysing and characterising documents, for manipulating their descriptions in searching, and for generating the index language used for these purposes. It concentrates on the literature from 1968 to 1973.

An Automatic Index Validity for Clustering
2010Many 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.

Automatic Video Database Indexing and Retrieval
Multimedia Tools and Applications, 1997The 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.

Automatically indexing documents
Proceedings of the 7th international conference on Intelligent user interfaces - IUI '02, 2002Authors 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 [

Indexing and automatic significance analysis
Journal of the American Society for Information Science, 1974AbstractIntellectual 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
2010Based 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 of full texts
Information Processing & Management, 1984Abstract 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
