STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR OR A JOINT INVENTOR

The following disclosure(s) are submitted under 35 U.S.C. § 102(b)(1)(A): DISCLOSURE(S): [Query Performance Prediction for Multifield Document Retrieval, Haggai Roitman et al., Published Sep. 14, 2020, 4 pages]

BACKGROUND

The present invention relates generally to the field of computing, and more particularly to a system for predicting the performance of a query in retrieving multifield documents.

Information Retrieval (IR) is the process of obtaining information system resources that are relevant to an information need from a large collection of those resources. Such resources may include books, journals, and other documents stored in a database. Query performance prediction (QPP) is a core IR task to estimate retrieval effectiveness in the absence of relevance judgments, i.e., human intervention. In many real-world retrieval settings, retrievable documents may be composed of several different fields on which a query is being evaluated, such as title, authors, related work, and question and answer (Q&A) fields. These fields are useful to evaluate in that they may contain the information which a user is seeking.

SUMMARY

According to one embodiment, a method, computer system, and computer program product for predicting a performance of a query in retrieving multifield documents is provided. The embodiment may include receiving a query from a user. The embodiment may also include retrieving a list of multifield documents from a corpus of documents in response to the query. The retrieved list may be obtained by searching the query over multiple fields in the corpus of documents. The embodiment may further include generating a pseudo-effective (PE) reference-list for each field in the corpus of documents. The embodiment may also include executing one or more existing query performance prediction (QPP) methods on the retrieved list and each generated PE reference-list. The embodiment may further include deriving one or more extended QPP methods based on the generated PE reference-lists and the retrieved list. The embodiment may also include estimating a performance of the query in obtaining the retrieved list of multifield documents based on the one or more extended QPP methods.
