Example Embodiment

[0024] The content of the present invention will be further described below in conjunction with specific embodiments.

[0025] The processing flow of the existing technology is such as figure 1 As shown, in text recommendation, unstructured text information cannot be directly used in the recommendation algorithm, and text preprocessing is required to extract the feature words and corresponding weights that best represent the text information in the text information. Preprocessing text information includes building a vector space model, feature word extraction and stop word removal.

[0026] The vector space model proposed by Salton et al. is a simple and efficient document representation model. The idea of ​​this model is that for any document set, based on its different feature words, form a document feature word vector space, and use the feature vector in the space to represent the document. There are usually two types of vector space models, namely Boolean vector space models a...

Abstract

The invention discloses a text recommendation method. The text recommendation method comprises the following steps of establishing a user model; preprocessing a text document; extracting feature vectors; calculating the optimal matching of synonyms among the feature vectors; determining a recommended text according to the similarity between the feature vectors and the user model. According to the method, a matching factor for semantic similarity among the synonyms is added on the base of the traditional angle cosine algorithm, the influence of the synonyms of the text on the similarity is considered, the levels of similarity between texts and between the text and the user model are more accurately calculated, and through experimental verification, the text recommendation method has the advantage of improving the accuracy rate by 20 percent averagely compared with the angle cosine algorithm and has high practical value.

Description

technical field [0001] The invention belongs to the field of text classification, and in particular relates to a text recommendation method. Background technique [0002] With the advent of the information age, in order to find the required information from the massive texts, a lot of reading is required. The traditional method is to manually classify texts, organize and organize them, and provide people with a relatively effective means of information acquisition. However, there are many disadvantages in this traditional text classification method: first, it consumes a lot of manpower, material resources and energy; second, the text classification method cannot meet the needs of all users. This requires us to explore effective ways to personalize text services and improve text reading efficiency. In this context, an algorithm to further filter documents according to the user interest model - text recommendation algorithm came into being. [0003] General text recommendat...
