30 results about "Controlled vocabulary" patented technology

Controlled vocabularies provide a way to organize knowledge for subsequent retrieval. They are used in subject indexing schemes, subject headings, thesauri, taxonomies and other knowledge organization systems. Controlled vocabulary schemes mandate the use of predefined, authorised terms that have been preselected by the designers of the schemes, in contrast to natural language vocabularies, which have no such restriction.

The invention relates to a method for automatically authenticating the value of documentary archives. The method includes the steps that the keywords of the tile and the full text of a documentary archive are extracted respectively; keyword distribution is conducted according to a controlled word list to obtain a keyword set; the keyword distribution result is calculated and discriminated, the archiving class is determined through keyword weight word frequency calculation, the retention period is determined through automatic annotation classification calculation, and then a first conclusion and a second conclusion which include the archiving class and the retention period respectively are obtained; the archiving class and the retention period are comprehensively recommended. A keyword base with the documentary archive retention value as the theme is built, the keywords in the tile and the document are extracted according to a related file, the archiving class of the documentary archive is determined, a means is provided for automatically authenticating the value of a large batch of documentary archives, the concurrent operation of authenticating the retention value of multiple documentary archives can be achieved, and the efficiency of authenticating the value of the documentary archives is improved.

Text subject indexing method and device, electronic device and computer storage medium

The embodiment of the invention relates to the technical field of text processing, and discloses a text subject indexing method and device, an electronic device and a computer storage medium, and thetext subject indexing method comprises the steps: determining a text word list of a to-be-indexed text; determining a text representation vector of the to-be-indexed text based on a predetermined wordvector library according to the text word list; then, based on a mapping table between subject words and common words, which is pre-established according to the controlled word table, determining thesubject words of which the association strength with any text word is greater than a first preset threshold value as the subject words of any text word to obtain the subject words corresponding to the text words respectively; determining a target subject word of the to-be-indexed text according to the text representation vector and the subject word corresponding to each text word, and performingsubject indexing on the to-be-indexed text through the target subject word. Therefore, the operand is greatly reduced, the comparison frequency is effectively reduced, and the text topic indexing efficiency is greatly improved.

Detection model compression method based on semantic segmentation

The invention discloses a detection model compression method based on semantic segmentation, and relates to the fields of artificial intelligence and computer vision. The method comprises the following steps: (1) pruning: 1) inputting a convolution kernel weight; 2) pruning is carried out on the trained network model to obtain a parameter space of sparse weights; (2) semantic segmentation: 1) performing semantic segmentation on the parameter space to obtain a hyper-parameter block and a central vocabulary, and calculating the central position of the hyper-parameter block; and 2) updating the original parameter space by using the central vocabulary. 3) judging whether the change of the current central vocabulary and the previous central vocabulary is smaller than a specified threshold value, if so, continuing to search parameters similar to the central vocabulary, and updating the central vocabulary and returning to the step 2); and ending the updating of the central vocabulary if the current vocabulary is smaller than the threshold. And (3) model storage: storing the hyper-parameter block boundary position, the parameter block center position and the center vocabulary value obtained by training. According to the method, hyper-parameters are used for describing the whole parameter space, overall compression of the parameter space is achieved, and the overall compression ratio ofthe model is increased to the maximum extent.
