Slide1

Overview of Task T3 of the LiveMusic project

Mathieu VEYRANDunder the supervision ofHassan Aït-Kaci

Slide2

This

presentation overviews the contents of Task T3 of the

LivEMUSIC Project: "Use of Ontological

Knowledge for Monitoring Applications"

This constitutes

essentially

the

work

of Mathieu VEYRAND

following

the

specifications

of Professor Hassan Aït-Kaci (

june

2015 -

october

2015)

The

LivEMUSIC

project

was

funded

as a PALSE (Programme Avenir Lyon Saint-Etienne)

Slide3

Input files

Data from Grand Lyon, extracted by Tanguy Raynaud (Task

T1)Velo'v stations is

chosen as the first

dataset348

objects

- 18

attributes

Raw

data in JSON - for ex:

Slide4

RDF Schema

The raw data is converted into a RDF

Schema, which is

latter used to make SPARQL queries

Slide5

Semantic Zoom

Master Degree's internship of Sofiene CHAMAKHI (Task T2)

"Semantic Zoom": specify approximation on data and use to query

Slide6

Supported Zooms

Numerical DataInterval ([0-10[ [10-20[ …)Difference (V +- d)Threshold (>,<,= T)

Slide7

.lmvt file

Format used by Lattice MinerRepresents a multi-

valued concept lattice

Slide8

Lattice Miner

Open source software for visualization and manipulation of concept latticesUsed to convert

the multi-valued lattice into

a binary lattice

Modification of the source code to convert the lattice

into

a format

supported

by CEDARA Concept-Station correspondance file is also generated

Slide9

.osf file

Representation of the concept lattice supported by CEDAR

Slide10

Concept - Station correspondance

Plain text file used to retrieve each station

associated with one concept

Slide11

CEDAR Reasoner

Software developed by Hassan Aït-Kaci and Samir AmirUsed

to find

the concept matching

our

criteria

Then

the correspondance file

is

used

to

retrieve

the stations

Slide12

Slide13

SPARQL Queries

GUI to make SPARQL queriesEasy filter on IDs

Slide14
