A new index model based on inverted index

2012 IEEE International Conference on Computer Science and Automation Engineering, 2012
Indexes are the kernels of search engines. This paper presents a Combination Inverted Index(CII), which is a new inverted index. CII contains three components: prime inverted index, appendix inverted index and deleted file list. The addition of appendix inverted index and deleted file list construct a new methodology of creating and updating the index.

INVERTED DISTANCE AND INVERTED WIENER INDEX

Advances and Applications in Discrete Mathematics, 2016
The Wiener index is the sum of distances between all pairs of vertices of a (connected) graph. In this paper, we define two novel graph invariants: the inverted distance and the inverted Wiener index. The inverted distance between any two different vertices u and v of a simple connected graph G is defined as: i(u, v) = D - d(u, v) + 1, where D denotes ...

The Inverted Multi-Index

IEEE Transactions on Pattern Analysis and Machine Intelligence, 2012
A new data structure for efficient similarity search in very large datasets of high-dimensional vectors is introduced. This structure called the inverted multi-index generalizes the inverted index idea by replacing the standard quantization within inverted indices with product quantization. For very similar retrieval complexity and pre-processing time,
