  • A multi-dimensional semantic pseudo-relevance feedback . . . - Nature
    The results demonstrate the effectiveness of utilizing multi-dimensional semantic information from pseudo-relevant documents to optimize query expansion
  • Rocchio algorithm - Wikipedia
    The Rocchio algorithm is based on a method of relevance feedback found in information retrieval systems which stemmed from the SMART Information Retrieval System developed between 1960 and 1964
  • Simple Yet Effective Pseudo Relevance Feedback with Rocchio’s Technique . . .
    In this thesis, we will discuss two implementations of pseudo relevance feedback: decades-old Rocchio’s Technique and more recent text classification As the reader might notice, both techniques are not “novel” anymore, e g , the emergence of Rocchio can even be dated back to the 1960s They are both proposed and studied before the neural age, where texts are still mostly stored as bag
  • A semantic framework for enhancing pseudo-relevance feedback with soft . . .
    Abstract In the field of information Retrieval (IR), Pseudo-relevance feedback (PRF) and Query Expansion (QE) techniques have garnered significant attention for their efficacy in enhancing retrieval effectiveness
  • Lecture 7: Relevance Feedback and Query Expansion
    The query-likelihood language model (earlier lecture) had no concept of relevance (if you remember) Relevance-Based language models take a probabilistic language modelling approach to modelling relevance The main assumption is that a document is generated from either one of two classes (i e relevant or non-relevant) Documents are then ranked

  • Relevance feedback and query expansion
    Relevance feedback on the web Evaluation of relevance feedback strategies Pseudo relevance feedback Indirect relevance feedback Summary The Rocchio algorithm for relevance feedback
  • Lecture 10: Relevance Feedback Query Expansion
    How can we improve recall in search? Main topic today: two ways of improving recall: relevance feedback and query expansion As an example consider query q : [ aircraft] “plane”, but not containing “aircraf A simple IR system will not return d for q Even if d is the most relevant document for q!
  • Proximity-based rocchios model for pseudo relevance
    ABSTRACT Rocchio’s relevance feedback model is a classic query expan-sion method and it has been shown to be effective in boosting information retrieval performance The selection of expan-sion terms in this method, however, does not take into ac-count the relationship between the candidate terms and the query terms (e g , term proximity) Intuitively, the proxim-ity between candidate
  • Pseudo-relevance Feedback Query Models
    Rocchio’s relevance feedback model is a classic query expansion method and it has been shown to be effective in boosting information retrieval performance Starting from the original query റ , the new query moves you some distance toward the centroid of the relevant documents and some distance away from the centroid of the non-relevant documents
