Alexandria at JCDL 2018

The 2018 ACM/IEEE Joint Conference on Digital Libraries (JCDL 2018) was held in Fort Worth (Texas, USA) on 3-6 June. The Alexandria project was again present in this annual venue with one full research paper. The paper, entitled  “Ranking Archived Documents for Structured Queries on Semantic Layers”, was presented by Dr. Pavlos Fafalios and is co-authored by Prof. Wolfgang Nejdl.

The paper introduces the problem of ranking archived documents for structured queries on semantic layers and proposes two ranking models (a probabilistic one and a Random Walk-based one) which jointly consider: i) the relativeness of a document to the query entities, ii) the timeliness of a document’s publication date, iii) the temporal relatedness of the query entities to other entities mentioned in the documents.

A preprint of the article is available at: http://l3s.de/~fafalios/files/pubs/fafalios2018jcdl.pdf
