The voting model for people search

Craig Macdonald
2009 SIGIR Forum  
The assistance of Rodrygo Santos, David Hannah and Alan Furness with some of the experiments in this thesis are also appreciated.  ...  The thesis investigates how persons in an enterprise organisation can be ranked in response to a query, so that those persons with relevant expertise to the query topic are ranked first.  ...  for pseudo-relevance feedback.  ...

Pretrained Transformers for Text Ranking: BERT and Beyond [article]

Jimmy Lin, Rodrigo Nogueira, Andrew Yates
2021 arXiv   pre-print
This survey provides an overview of text ranking with neural network architectures known as transformers, of which BERT is the best-known example.  ...  (i.e., result quality) and efficiency (e.g., query latency, model and index size).  ...  Special thanks goes out to two anonymous reviewers for their insightful comments and helpful feedback.  ...

TREC CAsT 2019: The Conversational Assistance Track Overview [article]

Jeffrey Dalton, Chenyan Xiong, Jamie Callan
2020 arXiv   pre-print
Relevance assessments are provided for 30 training topics and 20 test topics.  ...  The results show a gap between automatic systems and those using the manually resolved utterances, with a 35% relative improvement of manual rewrites over the best automatic system.  ...  Passage retrieval and ranking used standard BM25 ranking with pseudo-relevance feedback. Re-ranking was treated as a classification task with class probabilities used for re-ranking.  ...

Semantic Mapping in Video Retrieval

Maaike H.T. de Boer
2018 SIGIR Forum  
In our experiments, we focus on the first run of the video event retrieval system and, therefore, do not include pseudo-relevance feedback.  ...  Another interesting option is to examine the use of (pseudo-)relevance feedback. This feedback can also be combined with, for example, common knowledge sources.  ...

Comparing citation contexts for information retrieval

Anna Ritchie, Stephen Robertson, Simone Teufel
2008 Proceeding of the 17th ACM conference on Information and knowledge mining - CIKM '08  
Using the Lemur toolkit constrained the method that we used to weight citation terms; we would like to experiment with a more realistic implementation of term weighting.  ...  In previous work, words from citing documents have been used as an alternative representation of the cited document but no previous experiment has combined them with a full-text document representation  ...  Using the same judgements for feedback and evaluation is an unrealistic experiment.  ...

Pretrained Transformers for Text Ranking: BERT and Beyond

Andrew Yates, Rodrigo Nogueira, Jimmy Lin
2021 Proceedings of the 14th ACM International Conference on Web Search and Data Mining  
This survey provides an overview of text ranking with neural network architectures known as transformers, of which BERT is the best-known example.  ...  The combination of transformers and self-supervised pretraining has, without exaggeration, revolutionized the fields of natural language processing (NLP), information retrieval (IR), and beyond.  ...  Although transformer architectures and pretraining techniques are recent innovations, many aspects of how they are applied to text ranking are relatively well understood and represent mature techniques  ...
