The method comprises the following steps of: acquiring a data sample by calling browsing historical data and / or favorite data recorded by a browser of customer premise equipment and collecting keywords searched when a search engine is used by the customer premise equipment; extracting feature words from the data sample and acquiring the frequency of visiting the feature words by the customer premise equipment; obtaining all levels of interest categories according to the feature words from the customer premise equipment, wherein each level of interest category comprises multiple interest classes; and obtaining the interest value of each interest class in each level of interest category as for the customer premise equipment so as to establish the interest model of the customer premise equipment. By the method and device, a great amount of information resources provided by a browser and the search engine are utilized fully, the interests of customers are effectively reflected, and individual service can be recommended for customers accurately according to the interest model.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a method and device for establishing an interest model. Background technique [0002] Traditional browsers and search engines provide a large number of information resources, but because they do not take into account the user's personal interests, different users get the same information using browsers and search engines, this kind of indiscriminate information resources cannot Meet the individual needs of users. Therefore, the personalized recommendation service based on user interests has become a research and development hotspot. [0003] In the personalized recommendation service, the research on user interest model becomes the core and key technology. At present, the modeling methods of the user interest model mainly include: manual custom modeling, that is, the modeling method that is input or selected by the user, which is completely dependent on the user and cannot acc...

At present, the modeling methods of the user interest model mainly include: manual custom modeling, that is, the modeling method that is input or selected by the user, which is completely dependent on the user and cannot accurately reflect the user's interest; example modeling, that is, A modeling method in which users provide interest-related examples and category attributes. This method requires users to mark pages to obtain examples during browsing, which interferes with users' normal browsing; automatic modeling, that is, based on users' browsing content and browsing behavior Construct a user model, the modeling process does not require the user to actively provide information, and will not cause interference to the user, but this method is still in its infancy, and cannot fully utilize the large amount of information resources provided by browsers and search engines, and cannot effectively reflect user interest
