Multilingual Task

50 equivalent topics for each of the 13 sub-collection languages will be provided. The multilingual ad-hoc task uses all 50 topics (CHIC-051 - CHIC-100), the semantic enrichment task uses only topics CHIC-051 - CHIC-075.

The topic set for the 2013 edition consists of 50 topics sampled both from Europeana logs and intellectually developed. The topics from Europeana query logs comprise queries for people, places, work titles (e.g. Mona Lisa), events or subjects. The intellectually derived topics mostly comprise topical queries. We down-sampled the proportion of named-entity topics in this year's topic set (from 60% in 2012 to about 20% this year) to put more emphasis on the more difficult topical queries. For comparison purposes, we also included topics from CHiC 2012. Topics have the following format:

<topic lang="eng">
<identifier>CHIC-051</identifier>
<title>chardonne</title>
<description>Jacques Chardonne, Writer (FR) OR place in Switzerland</description>
</topic>

Where:

<topic lang="eng"> marks the begin and language of a topic.
<identifier> is the query identifier
<title> is the actual query
<description> is a description of the content that will be used for relevance assessment.

THE DESCRIPTION FIELD MAY NOT BE USED FOR RETRIEVAL EXPERIMENTS.

Update (11 March 2013): The topics for both multilingual ad-hoc and semantic enrichment are now ready to be released. Please send email to vivien.petras@ibi.hu-berlin.de to receive access to the topics.
