Factual or Satisfactory: What Search Results Are Better?
نویسندگان
چکیده
An interesting issue “whether the factual search result is better than the satisfactory one?” is discussed in this paper, and all effort is to illustrate the publicly recognized conception “the supreme satisfactory result is optimal” could lead Information Retrieval astray. By contrast, we propose a new hypothesis “the factually result should be the optimal although sometimes unsatisfactory”. To implement the pilot study on this, we developed a search-engine (Google) based labeling platform and designed a new evaluation method involving user experiences. The results on the platform show the existence of bias on determining the optimal search results (factual or satisfactory). And the very different performances of NDCG and our evaluation metric demonstrate the weakness of current ranking algorithms in mining and recommending the long-term effective information.

متن کاملComprehension of factual, nonfactual, and counterfactual conditionals by Iranian EFL learners
A considerable amount of studies have been established on conditional reasoning supporting mental model theory of propositional reasoning. Mental model theory proposed by Johnson- larid and Byrne is an explanation of someone's thought process about how something occurs in the real world. Conditional reasoning as a kind of reasoning is the way to speak about possibilities or probabilities. The a...
متن کاملA Monte Carlo-Based Search Strategy for Dimensionality Reduction in Performance Tuning Parameters
Redundant and irrelevant features in high dimensional data increase the complexity in underlying mathematical models. It is necessary to conduct pre-processing steps that search for the most relevant features in order to reduce the dimensionality of the data. This study made use of a meta-heuristic search approach which uses lightweight random simulations to balance between the exploitation of ...
