Abstract

The invention provides a retrieval method, relates to the technical field of retrieval, and can be applied to the financial field or other fields. The retrieval method comprises the following steps: obtaining a retrieval word; similarity matching is carried out on the retrieval word and at least one topic model in a retrieval library to obtain a target topic model, and the topic model comprises a model constructed according to one type of unstructured files after clustering is carried out on the unstructured files through a clustering algorithm; performing vectorization processing on the search word to obtain a first vector; obtaining at least one second vector in the target topic model, wherein the second vector comprises a vector obtained by vectorizing an unstructured file used for constructing the target topic model; performing similarity matching on the obtained second vector and the first vector to obtain a target vector; and obtaining an unstructured file matched with the target vector, and taking the unstructured file as a retrieval result. The invention further provides a retrieval device, electronic equipment, a storage medium and a program product.

Description

technical field [0001] The present disclosure relates to the field of retrieval technology, can be applied to the financial field, and can also be applied to other fields, and specifically relates to a retrieval method, apparatus, electronic device, storage medium and program product. Background technique [0002] With the rapid development of network technology, products are constantly updated and iterated. With the launch of the product, massive amounts of unstructured data corresponding to the product, such as reference documents, are generated. Unstructured data refers to data stored in the form of various types of files. Usually, the content of the file cannot be directly known. It needs to be opened and browsed through corresponding tools. This type of data has no prescribed structure and is not easy to manage. [0003] Unstructured data contains important information associated with products. When business personnel want to refer to historical products to assemble ne...
