Problems solved by technology

However, most recommendation systems do not consider the context of the user at that time, and the recommended music cannot meet the psychological needs of the user at the time, because many users actually rely on the situation, event or physical environment at the time rather than the singer. waiting to choose music

Embodiment Construction

[0022] The purpose and effects of the present invention will become more apparent by describing the present invention in detail below in conjunction with the accompanying drawings.

[0023] Such as figure 1 As shown, the music recommendation method based on the user's current geographic location and physical environment in the present invention specifically includes the following implementation steps:

[0024] Step 1: Crawl photo collections with GPS information from photo sites.

[0025] In the process of crawling data, the API single photo access speed provided by the photo website is too slow (crawl according to the photo ID), and the demand for photos is tens of millions or even hundreds of millions. This invention uses the dichotomy method to detect the most suitable one Crawl the number of photos, and then download photos in batches (download all photos in a certain area in batches), which greatly reduces network IO access. For example, the speed of crawling photos from...

Abstract

The invention discloses a music recommending method based on the current geographical position and physical environment of a user. The invention discloses a reasonable music recommend framework, and designs an expression structure of the current position and physical environment characteristics of the user. This structure supports an effective vector matching algorithm, and meanwhile, as to spatial attributes and text attributes of a large number of picture objects, the invention adopts a variant space index structure which supports efficient insertion, deletion and updating operations. On the basis of the index structure, the semantic property of music lyric and the spatiality and the semantic property of a picture are combined, so that the user can obtain the optimal recommended music according to the current position and the physical environment of the user.

Description

technical field [0001] The invention relates to an indexing mechanism and a query method in the field of spatial databases, and a retrieval and recommendation technology for massive multimedia objects in the field of information retrieval, and in particular to a music recommendation method based on the user's current geographic location and physical environment. Background technique [0002] In the field of spatial databases, in order to quickly and effectively access massive spatial data, experts and scholars have proposed a large number of spatial index methods, common index methods include grid (Grid), quadtree (Quad-Tree), R-index, R *Tree index, K-D-B tree index, Hilbert curve index. On this basis, a variety of unique queries and their solutions are proposed, such as nearest neighbor query, K nearest neighbor query, continuous neighbor query, reverse nearest neighbor query, farthest neighbor query, skyline query. These spatial indexes usually organize spatial objects i...
