In addition, we also combine the traditional pseudo-relevance feedback query expansion method with the proposed query expansion method. ...
In this sense, we represent keywords in user queries as vectors, sum all the keyword vectors, and use the obtained query vectors to select the expansion words. ...

Temporal feedback improves over standard lexical feedback (with and without human judgments), illustrating that temporal relevance signals exist independently of document content. ...
We explore this question in the context of tweet search and temporal feedback: starting with an initial set of results from a baseline retrieval model, we estimate the temporal density of relevant documents ...
From the top k reranked documents, estimate feedback models: in the pseudo-relevance feedback case, this involves selecting the top k documents and assuming that they are relevant. 3 Training γ led to ...

Existing pseudo-relevance feedback methods typically perform averaging over the top-retrieved documents, but ignore an important statistical dimension: the risk or variance associated with either the individual ...
We find that resampling documents helps increase individual feedback model precision by removing noise terms, while sampling from the query improves robustness (worst-case performance) by emphasizing terms ...
[17] proposed an approach to improving the robustness of pseudo-relevance feedback using a method they call selective sampling. ...

Furthermore, we present a novel Selective Fixation and Non-Fixation Error (sFNE) loss to make proposed feedback model better learn distinguishable eye-fixation-based features. ...
We first use the proposed feedback model to learn saliency distribution from pseudo-ground-truth. Afterwards, we fine-tune the feedback model on existing eye-fixation datasets. ...
In this experiment, we use a mixture training set with Pseudo-Saliency (900 samples) and MIT1003 (900 samples) for fine-tuning. ...
