The centrality of user modeling to high recall with high precision search

Dan Brassil, Christopher Hogan, Simon Attfield
2009 2009 IEEE International Conference on Systems, Man and Cybernetics  
In this paper, we report on systematic User Modeling (UM) and the use of a system-internal agent (proxy) to produce a hybrid human-computer system that achieves extraordinarily high performance on mediated  ...  We illustrate how these components provide a framework with which a user and a proxy co-construct a shared representation of information needs and mutual knowledge.  ...  During UM, a combination of issue-focusing and data-focusing techniques are used such as employing questionnaires, exemplar documents drawn from the target corpus, and user interviews to draw the user's  ...

Generating Biomedical Question Answering Corpora from Q&A Forums

Andre Lamurias, Diana Sousa, Francisco M. Couto
2020 IEEE Access  
We present a method to automatically extract question-article pairs from Q&A web forums, which can be used for document retrieval, a crucial step of most QA systems.  ...  Also, we demonstrated that the articles given as answers are significantly similar to the questions and trained a state-of-the-art deep learning model that obtained similar performance to using a dataset  ...  It is more intuitive for users to retrieve information using natural language than through keyword-based search.  ...

Summaries on the Fly: Query-Based Extraction of Structured Knowledge from Web Documents [chapter]

Besnik Fetahu, Bernardo Pereira Nunes, Stefan Dietze
2013 Lecture Notes in Computer Science  
A large part of Web resources consists of unstructured textual content. Processing and retrieving relevant content for a particular information need is challenging for both machines and humans.  ...  While information retrieval techniques provide methods for detecting suitable resources for a particular query, information extraction techniques enable the extraction of structured data and text summarization  ...  The manually created summaries extracted from the NYT corpus were used as reference summaries.  ...

Cross Language Information Retrieval (CLIR): A Survey of Approaches for Exploring Web Across Languages

Most of the present monolingual information retrieval systems can retrieve documents in the language of query only, missing the information in other languages that may be more relevant to the user.  ...  Starting with the most fundamental approaches of translation, it is attempted to study and present a review of more advanced approaches for enhancing the retrieval results in CLIR proposed by various researchers  ...  The user may also expect the information to be retrieved in a language in which the user is more comfortable.  ...

Expedition possesses a suite of ad-hoc and diversity based retrieval models to address complex information needs; a newspaper-style user interface to allow for larger textual previews and comparisons;  ...  However these systems have been designed for more general users rather than scholars. Scholars have more complex information needs in comparison to general users.  ...  For instance, initially the user may want an overview and subsequently more focused results.  ...

Literature Explorer: effective retrieval of scientific documents through nonparametric thematic topic detection

Shaopeng Wu, Youbing Zhao, Farzad Parvinzamir, Nikolaos Th. Ersotelos, Hui Wei, Feng Dong
2019 The Visual Computer  
While these publications offer rich and valuable information, the scale of the datasets makes it difficult for the researchers to manage and search for desired information efficiently.  ...  We propose a novel topic mining method that is able to uncover "thematic topics" from a scientific corpus.  ...  The topics are orthogonal to each other to capture most information in the text, which makes its results useful as a representation of documents for classifications.  ...
