Problems solved by technology

Existing geolocation-based topic models are able to mine themes of multiple aspects of the location. These methods target either the global themes of landmarks, such as the attributes that all landmarks have, or the location themes of landmarks, such as the unique appearance of landmarks, but Ignores mining of landmarks in terms of time

Embodiment Construction

[0015] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0016] figure 1 It is a flow chart of the landmark information retrieval method based on multimedia data mining in the present invention. The method realizes landmark information retrieval and summary in travel recommendation by mining three types of topics of landmarks, ie global topic, location topic and time topic. Such as figure 1 As shown, the method includes three parts: 1) landmark database construction, 2) spatio-temporal topic modeling, and 3) topic visualization. Specifically, the method includes the following steps:

[0017] Step S1, constructing a landmark database, the landmark database includes a list of landmarks, a collection of landmark pictures, and metadata information corresponding to each landmark pi...

Abstract

The invention discloses a search method of landmark information mined based on multimedia data. The search method includes establishing landmark data base comprising a landmark list, a landmark picture collection and metadata information corresponding to each of landmark pictures, establishing space-time theme model used for mining overall theme collection, location theme collection and time theme collection from the landmark database, and utilizing the space-time theme model to mine themes and display landmark search results as themes for inputted search targets. Each theme in theme collections is displayed by words of text dictionaries and visual words of visual dictionaries. With the search method, landmark information search and summarizing problems in tourism recommendation and all kinds of landmark themes, especially time theme mining problem are solved, and defects brought by single text mode in landmark information summary are offset.

Description

technical field [0001] The invention relates to the field of multimedia data mining, in particular to a landmark information retrieval method based on multimedia data mining. Background technique [0002] The rapid development of tourism makes tourism gradually become a part of people's daily life. Landmarks are must-visit places for people to visit due to their unique physical, historical and cultural characteristics. The rapid development of picture-sharing websites has resulted in explosive growth of landmark picture resources. While enjoying these rich landmark resources, users are also faced with the problem of information overload. How to effectively organize and structure these landmark resources and help users quickly understand all aspects of landmarks, so as to make appropriate travel plans, has been solved. It has become a topic of common concern in academia and industry. The more common method is to use various modal information such as geographic tags, text a...
