Real Query Log from the Similarity Search Engine MUFIN
This query log was published in the publication . The authors are the Head of the DISA Laboratory, and also one of the members of the Drago-HPC Research Group and his advisors in his PhD.
This is a query log obtained from an in-production Similarity Search Engine called MUFIN .
Regarding the format of the file of this query log, each line represents a query, which is an image. Each image (or query) contains 6 elements. The first element is just an ID. The following five elements are the MPEG descriptors: (1) Colour Layout (dimension=12), (2) Colour Structure (dimension=64), (3) Edge Histogram (dimension=80), (4) Scalable Colour (dimension=64), and (5) Region Shape (dimension=36).
All the 6 elements (ID and MPEG descriptors) are separated with a tabulator ('\t').
There are 68,919 queries in this file. The first line is not a query, it is just a description of the previous 6 elements.

Crawling the Chilean Web
Thesis of the program Computer Science Engineering at Catholic University of Maule
The main objective of this thesis is to analyze the features and behavior of the Chilean Web. For this we need to visit and retrieve the Web sites with .cl domain. We will compare our results to previous state-of-the-art studies about the Chilean Web.
