Abstract (en)

[origin: WO2021191392A1] The present invention relates to a computer-implemented method for the analogue retrieval of documents comprising at least one piece of textual information from a set of documents E comprised in a first database and whose textual information most closely corresponds to a search term R, comprising the following steps: a. Generating a second database comprising a list of words produced by lemmatisation of the textual information of the documents of the first database; b. Generating a descriptor vector V of numerical values for each document of the first database, using a vectorisation function F for vectorising the textual information; c. Training a self-organising map C comprising a network P of neurons p by projecting the descriptor vectors V onto the self-organising map C, each neuron p of the self-organising map C corresponding to a weight vector W of numerical values; d. Allocating each document of the first database to the neuron p of the self-organising map C whose corresponding weight vector W is the smallest distance from the descriptor vector V of the document to be allocated; e. Generating, using the vectorisation function F and the second database, a search vector K of numerical values for the search term R; f. Determining the neuron pbest of the self-organising map C whose weight vector W is the smallest distance from the search vector K; and, g. Determining the documents of the first database allocated to the neuron pbest of the self-organising map C.
