Job Vacancies experiment (1)

- Idea about the experiment: Rome Workshop (May,2014)

- Started with identifying web sites which advertise jobs

- and searching for available APIs for websites - UNECE Task Team consisted of representatives

from Austria, Hungary, Italy, Netherlands, Sweden and Slovenia

Job Vacancies experiment (2)

Goals:- Overview of the methodologies of calculation of

JV statistics at NSIs- Identification of possible web scraping tools - Determination of BD methodology of calculation

of JV statistics - Testing the BD quality indicators proposed by

UNECE Quality Task Team

Overview of the methodologies of calculation of JV statistics at NSIs

By EU regulation it is prescribed to publish quarterly statistic on JV data:- Totals of advertised JV on national level- Totals on domains defined by size of units- Totals on domains defined by NACE activity groups

Aim of the Irobot tool• IRobotSoft for Visual Web Scraping • IRobotSoft is a visual Web robot software for Web

scraping and Web automation. With IRobotSoft, you can scrape tons of data from the deep Web with a single click! You don't need to have computer skills to do this! IRobotSoft is for Everyone! Follow our discussions and become a Web geek!

• for novice data collectors • for Web testers • for data experts

Basic Steps

1. Define the name of the Irobot

2. Define the name of the Task

3. Copy and paste the link of desired website into the URL

4. Start Recording Actions

5. Give names to the „scraped“ variables

6. Save the variables

7. Use the option „Repeat Property“

Determination of BD methodology of calculation of JV statistics (1)

- Cleaning of data - Methodology for the replacement of existing statistics (on

the level of NSi)- Methodology for the calculation of new statistics (on the

level of NSi)- Methodology for the calculation of new statistics

(international level)

Interface with the parameters

Document:

Information which could be extracted from the Slovenian Websites and the proposed statistics for the job vacancies.doc

Determination of BD methodology of calculation of JV statistics (3)

One of the step in the statistical processing of JV data is assigning the ID of the Legal Unit from the Business Register.

Linking the ID to the „scraped“ unit enables us to get the information about the activity and size of LeU (according to number of employees)

Testing the BD quality indicators proposed by Quality Team

Quality framework consists of three quality hyperdimensions: input, throughput and output hyperdimension

14

Conclusions (1)BD could be used as a source: • for new types of statistics• for existing statistics • for validation of existing statistics

In case of scraping of JV data:• Change of mode of collection • Validation of data collected by traditional way

(administrative sources, questionnaire• Flash statistics

15

Conclusions (2)Before the JV BD source is employed in regular statistical production the scraping tools, procedures of manipulation of data and statistics must be carefully tested in period of at least one year in order to ensure stability of sources and statistics.
