Embodiment 1
[0065] In practical applications, the semantic information of video objects has a strong structure, usually including video name, introduction, year, director, starring role, screenwriter, etc. Due to the characteristics of the attributes, there are complex correlations between videos, just like a director's program , programs of the same year and so on. Therefore, establishing a relationship between videos, that is, program relationship search, can enrich search results, and at the same time, program relationship search is a new search method.
[0066] A video program search method based on program relationship provided by the embodiment of the present invention is a new search method. The schematic diagram of the realization principle of the method is as follows figure 2 As shown, first establish the relationship between programs, establish an attribute relationship model and a relationship calculation model, and establish a relationship network between multiple video progr...
Embodiment 2
[0100] This embodiment provides a search device for video programs based on program relationship, and its specific implementation structure is as follows Figure 6 As shown, it can specifically include the following modules:
[0101]Relational network establishment module 61, is used for calculating the relation between two video programs, establishes the relational network between a plurality of video programs;
[0102] The search vector processing module 62 is used to perform structural processing on the search keywords input by the user to obtain a search vector, extract the relevant information of the video program from the search vector, and use the relevant information to calculate the formula through the set relationship value Calculate the relationship value between the search vector and each video program respectively;
[0103] The initial search processing module 63 is used to use each video program whose relationship value with the search vector is greater than the...

Abstract
The invention provides a searching method and a searching device for video programs based on a program relationship. The searching method mainly comprises the following steps: establishing a relationship network among the video programs, and performing structural processing on a searching keyword input by a user to obtain a searching vector; extracting relevant information of video programs from the searching vector, and respectively calculating a relationship value between the searching vector and each video program according to a set relationship value calculating formula by utilizing the relevant information; taking each video pogrom with the relationship value between the searching vector and each video program greater than a set relationship judging threshold value as an initial video searching result corresponding to a searching keyword, expanding the initial video searching result by utilizing the relationship network, thereby obtaining the final video searching result. The searching method realizes expanding the searching vector corresponding to the searching keyword and the initial video searching result through the program relationship network, so that the searching results are enriched, and one-dimensional searching results are extruded to form multi-dimensional video searching results.
Description
technical field [0001] The invention relates to the technical field of video search, in particular to a method and device for searching video programs based on program relationship. Background technique [0002] The current video or video management website has a one-dimensional search function for video programs. The schematic diagram of the realization principle of the one-dimensional search function is as follows figure 1 As shown, it is generally realized by matching the semantic information such as the name and introduction of the video by keywords. The relationship between a single data object in the search result set of the above-mentioned one-dimensional search and the search condition presents a direct correlation, and the search results form a program sequence according to their time order or title dictionary order. [0003] The disadvantage of the above-mentioned one-dimensional search is that all the individual data in the search results obtained by the one-dime...
