Entity Linking and Retrieval for Semantic Search (WSDM 2014)

This morning, we presented the last edition of our tutorial series on Entity Linking and Retrieval, entitled “Entity Linking and Retrieval for Semantic Search” (with Krisztian Balog and Daan Odijk) at WSDM 2014! This final edition of the series builds upon our earlier tutorials at WWW 2013 and SIGIR 2013. The focus of this edition lies on the practical applications of Entity Linking and Retrieval, in particular for semantic search: more and more search engine users are expecting direct answers to their information needs (rather than just documents). Semantic search and its recent applications are enabling search engines to organize their wealth of information around entities. Entity linking and retrieval is at the basis of these developments, providing the building stones for organizing the web of entities.

This tutorial aims to cover all facets of semantic search from a unified point of view and connect real-world applications with results from scientific publications. We provide a comprehensive overview of entity linking and retrieval in the context of semantic search and thoroughly explore techniques for query understanding, entity-based retrieval and ranking on unstructured text, structured knowledge repositories, and a mixture of these. We point out the connections between published approaches and applications, and provide hands-on examples on real-world use cases and datasets.

As before, all our tutorial materials are available for free online, see http://ejmeij.github.io/entity-linking-and-retrieval-tutorial/.

Online Religious Studies

Data transitions have revolutionized many scientific disciplines, starting with the exact sciences, then the life sciences, and now the social sciences and humanities are in the process of making the transition to becoming data intensive sciences, with descriptions through quantitative measurements. New analysis tools, and publicly accessible utterances, opinions, transactions and interactions resulting from widespread Internet and social media usage facilitate new, data-intensive research methods in disciplines that have so far relied on small-scale literature and/or panel-based studies. To illustrate the new possibilities, we report on a pilot carried out by a cross-disciplinary team consisting of computer scientists and researchers in religious studies. In the latter area, research is often focused on mapping out the convictions, hopes, and beliefs of groups of people, be it within certain religions or within any other group, such as those defined by a political party.

In the pilot, religious scholars examined the core keywords in a left-wing political party in order to determine their hopes and beliefs. Rather than following their standard way-of-working, they were equipped with a search engine with an index of content crawled from discussion forums, the party’s web site plus a range of online publications relating to the party and going back to 1990. In this paper we focus on lessons learned and on methodological innovations for religious scholars as well as for computer scientists building the enabling technology.
